Written by: Iban Cereijo Jairo Chapela Copyright (C) 2004-2018 Iban Cereijo Copyright (C) 2004-2018 Jairo Chapela Description =========== Lingot is a musical instrument tuner. It's accurate, easy to use, and highly configurable. Originally conceived to tune electric guitars, it can now be used to tune other instruments. It looks like an analog tuner, with a gauge indicating the relative shift to a certain note found automatically as the closest note to the estimated frequency. Requirements ============ * Sound card. * Linux kernel with audio support (OSS, ALSA, JACK or PulseAudio). * GTK+ library, version 3.10. Installation ============ If you are building a release, just type: > ./configure > make install If you are building a development version obtained from our VCS you will need to create the configure script first by calling: > ./bootstrap Lingot supports the following audio systems/servers: OSS ALSA JACK PulseAudio You can enable/disable each of them with the following options passed to the configure script, all of them enabled by default: --enable-oss= --enable-alsa= --enable-jack= --enable-pulseaudio= Also, the depedency to libfftw can be enabled/disabled with --enable-libfftw= Please, see the INSTALL file. Synopsis ======== lingot [-c config] The -c option causes the search of a file named {config}.conf in the ~/.lingot folder. For example: lingot -c bass will take the configuration file ~/.lingot/bass.conf. This is useful for maintaining different configurations for different instruments. It's also possible to load and save configuration files from the GUI. The default configuration file is ~/.lingot/lingot.conf. Configuration file ================== When lingot is launched for the first time, the default configuration file ~/.lingot/lingot.conf will be created. The default values are optimized for tuning electric guitars, other musical instruments might require these values to be slightly changed (a good practice would be to have a configuration file for each instrument). The options can be changed via GUI. There is a wide range of options, with the purpose of keeping the maximum configurability. Some background in signal processing is needed for a good understanding of all of their effects. We detail the main options that constitute this file, and we recommend to make changes depending on the desired tuning precision and demanded CPU time. If you don't understand the effects of some options, then just try different values or, even better, don't change them. AUDIO_SYSTEM Audio system switch. Possible values: OSS ALSA [default value] JACK PulseAudio AUDIO_DEV (OSS sound device) Selected sound device for the OSS audio system. The default value is '/dev/dsp'. AUDIO_DEV_ALSA (ALSA sound device) Selected sound device for ALSA, the default value is 'default'. AUDIO_DEV_JACK (JACK port) Selected sound port for JACK, the default value is 'default'. AUDIO_DEV_PULSEAUDIO (PulseAudio sound device) Selected sound device for PulseAudio, the default value is 'default'. ROOT_FREQUENCY_ERROR ("A" reference note shift) This option is used when we want to tune with a certain amount of shift in frequency. This can be useful when tuning an instrument against a recording with a shifted tuning. For example, if we hear an "A" note in a recording that it's a quarter of a tone over the real frequency (440 Hz), we can put 50 cents of shift here. It must be a real number, expressed in cents. The default value is 0. FFT_SIZE (Size of the FTT) A high value gets more accuracy, especially more precision locking the desired frequency, but it demands more CPU time. We must consider the time interval involved on the calculus before unnecessarily raising this value: having a buffer of 4096 samples for the FFT, and a sampling rate of 8 KHz, each transform needs the last 512 ms temporary values, so there is no point in putting a shorter temporal window. It must be an integer power of 2. The default value is 512 samples. TEMPORAL_WINDOW The length in time of the signal used to compute the final frequency. With higher values, we'll obtain a more accurate result, but also a slower response polluted by earlier notes. As a practical rule, we say that if we have a temporal window of 1 second, we must wait 1 second between two consecutive notes to obtain a correct tuning. Therefore, this parameter affects directly to the responsiveness of the tuner. The temporal window size in samples (obtained as the multiplication of its duration in seconds and the effective sampling rate) must be greater than the FFT buffer size. It must be a real number in seconds. The default value is 0.32 seconds. MIN_SNR To avoid tuning noise, this is the lower signal-to-noise ratio we require to start the tuning process. It's a real number whose units are dB. The default value is 20 dB. CALCULATION_RATE With higher calculations per second, the tuner gives us a better dynamic sensation, but it'll need more CPU time. It's a real number, in hertz, and the default value is 20 Hz. VISUALIZATION_RATE It has impact in the dynamism sensation achieved, but less in the computation time. There is no point having a calculation rate greater than the visualization rate. It's a real number, in hertz. The default value is 30 Hz. MINIMUM_FREQUENCY and MAXIMUM_FREQUENCY The minimum and maximum notes the instrument can tipically generate. These are not hard boundaries, but a guideline to help Lingot set its internal parameters. They are eal numbers, in hertz. The default values are 82.41 Hz (E2) and 329.63 Hz (E4) SCALE Definition of the scale used for the tuning. By default a 12 semitones equal-tempered scale is used. It contains several parameters: NAME: Scale name, only for your information. BASE_FREQUENCY: The absolute frequency - in hertz - of the first note. NOTE_COUNT: number of notes in the scale. NOTES: list of notes, being them pairs of name and frequency shift. The frequency shift can be expressed as a real number in cents or a division of integer values, encoding a frequency ratio, like '3/2' or '5/4'. Be careful with leaving wide gaps in frequency between each pair of adjacent notes, as the gauge range will adapt to the maximum of those distances. Try to use scales with at least 12 tones. lingot-1.0.1/NEWS0000644000175000017500000000751613320113677010441 00000000000000 Lingot 1.0.0 (2018-07-06) ------------------------- * Added PulseAudio support. * Migration to GTK+ 3.10 * Migration to graphic vectors with libcairo.

This reverts commit 7ebeb306cb9950c71e72214d23d69787f8b6a661. Revert "Separate chebychev filter stuff from memory allocation (new and destroy)." This reverts commit f322ed7c7f04c096bd81e8ecb5ce1262ae324d9b. 2018-06-13 Iban Cereijo Generate ChangeLog from git history. 2018-06-12 Iban Cereijo Corrections after the merge Merge branch 'master' into patches-nicolas-03 2018-06-12 Nicolas Boulenguez Fix various warnings. * Fix two missing #include "lingot-io-config.h". * Remove unused variables. * Make unused but required parameters explicit. * Mark some variables as unsigned, disambiguing some comparisons. Many more should be unsigned, avoiding such risks and implicit conversions. * Style: const static -> static const. * Add some const qualifiers. Fix position of some const qualifiers. const foo * bla: the referenced aera is read-only. foo * const bla: bla always referenc the same writable aera. Really compile with -Wall, add -Wextra. CXXFLAGS affects C++, not C. Remove unneeded LIBFFTW use outside lingot-fft.[ch]. Improve comments for scale allocation. Separate chebychev filter stuff from memory allocation (new and destroy). 2018-06-12 Nicolas Boulenguez Insert lingot_core_[start|stop] into lingot_core_[new|destroy]. These procedures were always called together. This simplifies the interface without changing the behaviour. Remove this block from _stop as it has no use right before _destroy. int spd_size = core->conf.fft_size / 2; memset(core->SPL, 0, spd_size * sizeof(FLT)); core->freq = 0.0; 2018-06-12 Iban Cereijo Updated i18n and added script for generating Changelog * ES and GL translations updated. * Removed other fuzzy translations. * Small corrections.

No need to check not null before free() Avoiding some hard-coded values Fixes SIGSEGV 2018-06-10 Iban Cereijo Revert "Applied patches from Nocilas Boulenguez (after converting them to unix format)." This reverts commit f14452c1ffcbfff0a48f62a79aabb22a85d311e0. Fixing unit tests. 2018-06-10 Nicolas Boulenguez Install less documentation, clean more files. INSTALL is of not useful outside the source tree. intltool-*.in were probably installed by error. (is src/lingot-logo.xpm useful?) intltool-*.in and po/Makefile.in.in may be removed by distclean. DISTCLEANFILES only considers files, not directories. In README, tell the user to create m4/, else intltoolize fails. 2018-06-10 Nicolas Boulenguez Declare some parameters const. Avoid dynamic allocation for type LingotConfig. Avoid dynamic allocation for type LingotFFTPlan. 2018-06-10 Nicolas Boulenguez Avoid dynamic allocation for type LingotScale. The pointer type was freed outside lingot-config-scale.c, so the patch should probably be checked. A NULL test is replaced with a readable enumeration. 2018-06-10 Nicolas Boulenguez Avoid dynamic allocation for type LingotCore. Avoid dynamic allocation for type LingotGauge. Avoid dynamic allocation for type LingotFilter. Remove unused _ names for audio handler and audio system properties structs.

Ensure unselected components are never called by not compiling them. Stop the program with an assertion if the audio_system is invalid or unset when calling a lingot_audio_ routine other than _new. Check overflow in audio system list. Avoid dynamic allocation for sample rates. Allocate read buffer on the stack instead of the heap. In pulseaudio, remove a duplicate computation of size_in_bytes. Avoid dynamic allocation for LingotAudioHandler. Use audio->audio_system==-1 instead of audio==NULL. Update autotool stuff. Autoconf documentation recommends the m4 subdirectory. Intltool documentation recommends DISTCLEANFILES. Avoid dynamic allocation for LingotAudioSystemProperties. This patch simplifies the code and fixes a memory leak (the structs themselves were never deallocated). Description: add GenericName to desktop file Also add keywords.

LINGOT is a musical instrument tuner. It's accurate, easy to use, and highly configurable. Originally conceived to tune electric guitars, it can now be used to tune other instruments.

It looks like an analogue tuner, with a gauge indicating the relative shift to a certain note, determined automatically as the closest note to the estimated frequency.

  • It's free software. LINGOT is distributed under the GPL license.
  • It's really quick and accurate, perfect for real-time microtonal tuning.
  • Easy to use. Just plug in your instrument and run it.
  • LINGOT is a universal tuner. It can tune many musical instruments, you only need to provide the temperaments.
  • Highly configurable via GUI. It’s possible to change any parameter while the program is running, without editing any file.

Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library.
