It is currently fairly complete for PCM devices, and has some support for mixers. If you find bugs in the wrappers please open an issue in the issue tracker. Please don't send bug reports regarding ALSA specifically. There are several bugs in the ALSA API, and those should be reported to the ALSA team - not me. This software is licensed under the PSF license - the same one used by the majority of the python distribution. Basically you can use it for anything you wish (even commercial purposes). There is no warranty whatsoever. # Installation ## PyPI To install pyalsaaudio via `pip` (or `easy_install`): ``` $ pip install pyalsaaudio ``` ## Manual installation *Note:* the wrappers need a kernel with ALSA support, and the ALSA library and headers. The installation of these varies from distribution to distribution. On Debian or Ubuntu, make sure to install `libasound2-dev`. On Arch, install `alsa-lib`. When in doubt, search your distribution for a package that contains `libasound.so` and `asoundlib.h`. First, get the sources and change to the source directory: ``` $ git clone https://github.com/larsimmisch/pyalsaaudio.git $ cd pyalsaaudio ``` Then, build: ``` $ python setup.py build ``` And install: ``` $ sudo python setup.py install ``` # Using the API The API documentation is included in the doc subdirectory of the source distribution; it is also online on [http://larsimmisch.github.io/pyalsaaudio/](http://larsimmisch.github.io/pyalsaaudio/). There are some example programs included with the source: * [playwav.py](https://github.com/larsimmisch/pyalsaaudio/blob/master/playwav.py) plays back a wav file * [playbacktest.py](https://github.com/larsimmisch/pyalsaaudio/blob/master/playbacktest.py) plays back raw sound data read from stdin * [recordtest.py](https://github.com/larsimmisch/pyalsaaudio/blob/master/recordtest.py) captures sound from the microphone and writes it raw to stdout. * [mixertest.py](https://github.com/larsimmisch/pyalsaaudio/blob/master/mixertest.py) can be used to manipulate the mixers. ././@PaxHeader0000000000000000000000000000002600000000000010213 xustar0022 mtime=1588279794.0 pyalsaaudio-0.10.0/TODO0000644000076500000240000000015013652634762013471 0ustar00larsstaff- Better example code (aplay,arecord,amixer workalike for example) - Implement MIDI/sequencer support. ././@PaxHeader0000000000000000000000000000002600000000000010213 xustar0022 mtime=1681594652.0 pyalsaaudio-0.10.0/alsaaudio.c0000644000076500000240000022512414416614434015112 0ustar00larsstaff/* -*- Mode: C;

alsaaudio¶

The alsaaudio module defines functions and classes for using ALSA.

alsaaudio.pcms([type=PCM_PLAYBACK])¶

List available PCM devices by name.

Arguments are:

  • type - can be either PCM_CAPTURE or PCM_PLAYBACK (default).

Note:

For PCM_PLAYBACK, the list of device names should be equivalent to the list of device names that aplay -L displays on the commandline:

$ aplay -L

For PCM_CAPTURE, the list of device names should be equivalent to the list of device names that arecord -L displays on the commandline:

$ arecord -L

New in 0.8

alsaaudio.cards()¶

List the available ALSA cards by name. This function is only moderately useful. If you want to see a list of available PCM devices, use pcms() instead.

alsaaudio.mixers(cardindex=- 1, device='default')¶

List the available mixers. The arguments are:

  • cardindex - the card index. If this argument is given, the device name is constructed as: ‘hw:cardindex’ and the device keyword argument is ignored. 0 is the first hardware sound card.

  • device - the name of the device on which the mixer resides. The default is 'default'.

Note: For a list of available controls, you can also use amixer on the commandline:

$ amixer

To elaborate the example, calling mixers() with the argument cardindex=0 should give the same list of Mixer controls as:

$ amixer -c 0

And calling mixers() with the argument device='foo' should give the same list of Mixer controls as:

$ amixer -D foo

Changed in 0.8:

  • The keyword argument device is new and can be used to select virtual devices. As a result, the default behaviour has subtly changed. Since 0.8, this functions returns the mixers for the default device, not the mixers for the first card.

PCM Objects¶

PCM objects in alsaaudio can play or capture (record) PCM sound through speakers or a microphone. The PCM constructor takes the following arguments:

class alsaaudio.PCM(type=PCM_PLAYBACK, mode=PCM_NORMAL, rate=44100, channels=2, format=PCM_FORMAT_S16_LE, periodsize=32, device='default', cardindex=- 1)¶

This class is used to represent a PCM device (either for playback and recording). The arguments are:

  • type - can be either PCM_CAPTURE or PCM_PLAYBACK (default).

  • mode - can be either PCM_NONBLOCK, or PCM_NORMAL (default).

  • rate - the sampling rate in Hz. Typical values are 8000 (mainly used for telephony), 16000, 44100 (default), 48000 and 96000.

  • channels - the number of channels. The default value is 2 (stereo).

  • format - the data format. This controls how the PCM device interprets data for playback, and how data is encoded in captures. The default value is PCM_FORMAT_S16_LE.

  • periodsize - the period size in frames. Each write should consist of periodsize frames. The default value is 32.

  • device - the name of the PCM device that should be used (for example a value from the output of pcms()). The default value is 'default'.

  • cardindex - the card index. If this argument is given, the device name is constructed as ‘hw:cardindex’ and the device keyword argument is ignored. 0 is the first hardware sound card.

This will construct a PCM object with the given settings.

Changed in 0.9:

  • Added the optional named parameters rate, channels, format and periodsize.

Changed in 0.8:

  • The card keyword argument is still supported, but deprecated. Please use device instead.

  • The keyword argument cardindex was added.

The card keyword is deprecated because it guesses the real ALSA name of the card. This was always fragile and broke some legitimate usecases.

PCM objects have the following methods:

PCM.pcmtype()¶

Returns the type of PCM object. Either PCM_CAPTURE or PCM_PLAYBACK.

PCM.pcmmode()¶

Return the mode of the PCM object. One of PCM_NONBLOCK, PCM_ASYNC, or PCM_NORMAL

PCM.cardname()¶

Return the name of the sound card used by this PCM object.

PCM.setchannels(nchannels)¶

Deprecated since version 0.9: Use the channels named argument to PCM().

PCM.setrate(rate)¶

Deprecated since version 0.9: Use the rate named argument to PCM().

PCM.setformat(format)¶

Deprecated since version 0.9: Use the format named argument to PCM().

PCM.setperiodsize(period)¶

Deprecated since version 0.9: Use the periodsize named argument to PCM().

PCM.read()¶

In PCM_NORMAL mode, this function blocks until a full period is available, and then returns a tuple (length,data) where length is the number of frames of captured data, and data is the captured sound frames as a string. The length of the returned data will be periodsize*framesize bytes.

In PCM_NONBLOCK mode, the call will not block, but will return (0,'') if no new period has become available since the last call to read.

In case of an overrun, this function will return a negative size: -EPIPE. This indicates that data was lost, even if the operation itself succeeded. Try using a larger periodsize.

PCM.write(data)¶

Writes (plays) the sound in data. The length of data must be a multiple of the frame size, and should be exactly the size of a period. If less than ‘period size’ frames are provided, the actual playout will not happen until more data is written.

If the device is not in PCM_NONBLOCK mode, this call will block if the kernel buffer is full, and until enough sound has been played to allow the sound data to be buffered. The call always returns the size of the data provided.

In PCM_NONBLOCK mode, the call will return immediately, with a return value of zero, if the buffer is full. In this case, the data should be written at a later time.

PCM.pause([enable=True])¶

If enable is True, playback or capture is paused. Otherwise, playback/capture is resumed.

PCM.polldescriptors()¶

Returns a tuple of (file descriptor, eventmask) that can be used to wait for changes on the mixer with select.poll.

The eventmask value is compatible with poll.register in the Python select module.

A few hints on using PCM devices for playback

The most common reason for problems with playback of PCM audio is that writes to PCM devices must exactly match the data rate of the device.

If too little data is written to the device, it will underrun, and ugly clicking sounds will occur. Conversely, of too much data is written to the device, the write function will either block (PCM_NORMAL mode) or return zero (PCM_NONBLOCK mode).

If your program does nothing but play sound, the best strategy is to put the device in PCM_NORMAL mode, and just write as much data to the device as possible. This strategy can also be achieved by using a separate thread with the sole task of playing out sound.

In GUI programs, however, it may be a better strategy to setup the device, preload the buffer with a few periods by calling write a couple of times, and then use some timer method to write one period size of data to the device every period. The purpose of the preloading is to avoid underrun clicks if the used timer doesn’t expire exactly on time.

Also note, that most timer APIs that you can find for Python will accummulate time delays: If you set the timer to expire after 1/10’th of a second, the actual timeout will happen slightly later, which will accumulate to quite a lot after a few seconds. Hint: use time.time() to check how much time has really passed, and add extra writes as nessecary.

Mixer Objects¶

Mixer objects provides access to the ALSA mixer API.

class alsaaudio.Mixer(control='Master', id=0, cardindex=- 1, device='default')¶

Arguments are:

  • control - specifies which control to manipulate using this mixer object. The list of available controls can be found with the alsaaudio.mixers() function. The default value is 'Master' - other common controls may be 'Master Mono', 'PCM', 'Line', etc.

  • id - the id of the mixer control. Default is 0.

  • cardindex - specifies which card should be used. If this argument is given, the device name is constructed like this: ‘hw:cardindex’ and the device keyword argument is ignored. 0 is the first sound card.

  • device - the name of the device on which the mixer resides. The default value is 'default'.

Changed in 0.8:

  • The keyword argument device is new and can be used to select virtual devices.

Mixer objects have the following methods:

Mixer.cardname()¶

Return the name of the sound card used by this Mixer object

Mixer.mixer()¶

Return the name of the specific mixer controlled by this object, For example 'Master' or 'PCM'

Mixer.mixerid()¶

Return the ID of the ALSA mixer controlled by this object.

Mixer.switchcap()¶

Returns a list of the switches which are defined by this specific mixer. Possible values in this list are:

Switch

Description

‘Mute’

This mixer can mute

‘Joined Mute’

This mixer can mute all channels at the same time

‘Playback Mute’

This mixer can mute the playback output

‘Joined Playback Mute’

Mute playback for all channels at the same time}

‘Capture Mute’

Mute sound capture

‘Joined Capture Mute’

Mute sound capture for all channels at a time}

‘Capture Exclusive’

Not quite sure what this is

To manipulate these switches use the setrec() or setmute() methods

Mixer.volumecap()¶

Returns a list of the volume control capabilities of this mixer. Possible values in the list are:

Capability

Description

‘Volume’

This mixer can control volume

‘Joined Volume’

This mixer can control volume for all channels at the same time

‘Playback Volume’

This mixer can manipulate the playback output

‘Joined Playback Volume’

Manipulate playback volumne for all channels at the same time

‘Capture Volume’

Manipulate sound capture volume

‘Joined Capture Volume’

Manipulate sound capture volume for all channels at a time
Mixer.getenum()¶

For enumerated controls, return the currently selected item and the list of items available.

Returns a tuple (string, list of strings).

For example, my soundcard has a Mixer called Mono Output Select. Using amixer, I get:

$ amixer get "Mono Output Select"
Simple mixer control 'Mono Output Select',0
  Capabilities: enum
  Items: 'Mix' 'Mic'
  Item0: 'Mix'

Using alsaaudio, one could do:

>>> import alsaaudio
>>> m = alsaaudio.Mixer('Mono Output Select')
>>> m.getenum()
('Mix', ['Mix', 'Mic'])

This method will return an empty tuple if the mixer is not an enumerated control.

Mixer.getmute()¶

Return a list indicating the current mute setting for each channel. 0 means not muted, 1 means muted.

This method will fail if the mixer has no playback switch capabilities.

Mixer.getrange([direction])¶

Return the volume range of the ALSA mixer controlled by this object.

The optional direction argument can be either PCM_PLAYBACK or PCM_CAPTURE, which is relevant if the mixer can control both playback and capture volume. The default value is PCM_PLAYBACK if the mixer has playback channels, otherwise it is PCM_CAPTURE.

Mixer.getrec()¶

Return a list indicating the current record mute setting for each channel. 0 means not recording, 1 means recording.

This method will fail if the mixer has no capture switch capabilities.

Mixer.getvolume([direction])¶

Returns a list with the current volume settings for each channel. The list elements are integer percentages.

The optional direction argument can be either PCM_PLAYBACK or PCM_CAPTURE, which is relevant if the mixer can control both playback and capture volume. The default value is PCM_PLAYBACK if the mixer has playback channels, otherwise it is PCM_CAPTURE.

Mixer.setvolume(volume[, channel][, direction])¶

Change the current volume settings for this mixer. The volume argument controls the new volume setting as an integer percentage.

If the optional argument channel is present, the volume is set only for this channel. This assumes that the mixer can control the volume for the channels independently.

The optional direction argument can be either PCM_PLAYBACK or PCM_CAPTURE, which is relevant if the mixer can control both playback and capture volume. The default value is PCM_PLAYBACK if the mixer has playback channels, otherwise it is PCM_CAPTURE.

Mixer.setmute(mute[, channel])¶

Sets the mute flag to a new value. The mute argument is either 0 for not muted, or 1 for muted.

The optional channel argument controls which channel is muted. The default is to set the mute flag for all channels.

This method will fail if the mixer has no playback mute capabilities

Mixer.setrec(capture[, channel])¶

Sets the capture mute flag to a new value. The capture argument is either 0 for no capture, or 1 for capture.

The optional channel argument controls which channel is changed. The default is to set the capture flag for all channels.

This method will fail if the mixer has no capture switch capabilities.

Mixer.polldescriptors()¶

Returns a tuple of (file descriptor, eventmask) that can be used to wait for changes on the mixer with select.poll.

The eventmask value is compatible with poll.register in the Python select module.

Mixer.handleevents()¶

Acknowledge events on the polldescriptors file descriptors to prevent subsequent polls from returning the same events again. Returns the number of events that were acknowledged.

A rant on the ALSA Mixer API

The ALSA mixer API is extremely complicated - and hardly documented at all. alsaaudio implements a much simplified way to access this API. In designing the API I’ve had to make some choices which may limit what can and cannot be controlled through the API. However, if I had chosen to implement the full API, I would have reexposed the horrible complexity/documentation ratio of the underlying API. At least the alsaaudio API is easy to understand and use.

If my design choises prevents you from doing something that the underlying API would have allowed, please let me know, so I can incorporate these needs into future versions.

If the current state of affairs annoys you, the best you can do is to write a HOWTO on the API and make this available on the net. Until somebody does this, the availability of ALSA mixer capable devices will stay quite limited.

Unfortunately, I’m not able to create such a HOWTO myself, since I only understand half of the API, and that which I do understand has come from a painful trial and error process.

Examples¶

The following example are provided:

  • playwav.py

  • recordtest.py

  • playbacktest.py

  • mixertest.py

All examples (except mixertest.py) accept the commandline option -c <cardname>.

To determine a valid card name, use the commandline ALSA player:

$ aplay -L

or:

$ python

>>> import alsaaudio
>>> alsaaudio.pcms()

mixertest.py accepts the commandline options -d <device> and -c <cardindex>.

playwav.py¶

playwav.py plays a wav file.

To test PCM playback (on your default soundcard), run:

$ python playwav.py <wav file>

recordtest.py and playbacktest.py¶

recordtest.py and playbacktest.py will record and play a raw sound file in CD quality.

To test PCM recordings (on your default soundcard), run:

$ python recordtest.py <filename>

Speak into the microphone, and interrupt the recording at any time with Ctl-C.

Play back the recording with:

$ python playbacktest.py <filename>

mixertest.py¶

Without arguments, mixertest.py will list all available controls on the default soundcard.

The output might look like this:

$ ./mixertest.py
Available mixer controls:
   'Master'
   'Master Mono'
   'Headphone'
   'PCM'
   'Line'
   'Line In->Rear Out'
   'CD'
   'Mic'
   'PC Speaker'
   'Aux'
   'Mono Output Select'
   'Capture'
   'Mix'
   'Mix Mono'

With a single argument - the control, it will display the settings of that control; for example:

$ ./mixertest.py Master
Mixer name: 'Master'
Capabilities: Playback Volume Playback Mute
Channel 0 volume: 61%
Channel 1 volume: 61%

With two arguments, the control and a parameter, it will set the parameter on the mixer:

$ ./mixertest.py Master mute

This will mute the Master mixer.

Or:

$ ./mixertest.py Master 40

This sets the volume to 40% on all channels.

To select a different soundcard, use either the device or cardindex argument:

$ ./mixertest.py -c 0 Master
Mixer name: 'Master'
Capabilities: Playback Volume Playback Mute
Channel 0 volume: 61%
Channel 1 volume: 61%

Introduction¶

Author

Casper Wilstrup <cwi@aves.dk>

Author

Lars Immisch <lars@ibp.de>

This software is licensed under the PSF license - the same one used by the majority of the python distribution. Basically you can use it for anything you wish (even commercial purposes). There is no warranty whatsoever.

Abstract

This package contains wrappers for accessing the ALSA API from Python. It is currently fairly complete for PCM devices and Mixer access. MIDI sequencer support is low on our priority list, but volunteers are welcome.

If you find bugs in the wrappers please use thegithub issue tracker. Please don’t send bug reports regarding ALSA specifically. There are several bugs in this API, and those should be reported to the ALSA team - not me.

What is ALSA¶

The Advanced Linux Sound Architecture (ALSA) provides audio and MIDI functionality to the Linux operating system.

Logically ALSA consists of these components:

  • A set of kernel drivers. — These drivers are responsible for handling the physical sound hardware from within the Linux kernel, and have been the standard sound implementation in Linux since kernel version 2.5

  • A kernel level API for manipulating the ALSA devices.

  • A user-space C library for simplified access to the sound hardware from userspace applications. This library is called libasound and is required by all ALSA capable applications.

More information about ALSA may be found on the project homepage http://www.alsa-project.org

ALSA and Python¶

The older Linux sound API (OSS) which is now deprecated is well supported from the standard Python library, through the ossaudiodev module. No native ALSA support exists in the standard library.

There are a few other “ALSA for Python†projects available, including at least two different projects called pyAlsa. Neither of these seem to be under active development at the time - and neither are very feature complete.

I wrote PyAlsaAudio to fill this gap. My long term goal is to have the module included in the standard Python library, but that looks currently unlikely.

PyAlsaAudio has full support for sound capture, playback of sound, as well as the ALSA Mixer API.

MIDI support is not available, and since I don’t own any MIDI hardware, it’s difficult for me to implement it. Volunteers to work on this would be greatly appreciated.

Installation¶

Note: the wrappers link with the alsasound library (from the alsa-lib package) and need the ALSA headers for compilation. Verify that you have /usr/lib/libasound.so and /usr/include/alsa (or similar paths) before building.

On Debian (and probably Ubuntu), install libasound2-dev.

Naturally you also need to use a kernel with proper ALSA support. This is the default in Linux kernel 2.6 and later. If you are using kernel version 2.4 you may need to install the ALSA patches yourself - although most distributions ship with ALSA kernels.

To install, execute the following: —

$ python setup.py build

And then as root: —

# python setup.py install

Testing¶

Make sure that aplay plays a file through the soundcard you want, then try:

$ python playwav.py <filename.wav>

If aplay needs a device argument, like aplay -D hw:CARD=sndrpihifiberry,DEV=0, use:

$ python playwav.py -d hw:CARD=sndrpihifiberry,DEV=0 <filename.wav>

To test PCM recordings (on your default soundcard), verify your microphone works, then do:

$ python recordtest.py -d <device> <filename>

Speak into the microphone, and interrupt the recording at any time with Ctl-C.

Play back the recording with:

$ python playbacktest.py-d <device>  <filename>

There is a minimal test suite in test.py, but it is a bit dependent on the ALSA configuration and may fail without indicating a real problem.

If you find bugs/problems, please file a bug report.

PCM Terminology and Concepts¶

In order to use PCM devices it is useful to be familiar with some concepts and terminology.

Sample

PCM audio, whether it is input or output, consists of samples. A single sample represents the amplitude of one channel of sound at a certain point in time. A lot of individual samples are necessary to represent actual sound; for CD audio, 44100 samples are taken every second.

Samples can be of many different sizes, ranging from 8 bit to 64 bit precision. The specific format of each sample can also vary - they can be big endian byte integers, little endian byte integers, or floating point numbers.

Musically, the sample size determines the dynamic range. The dynamic range is the difference between the quietest and the loudest signal that can be resproduced.

Frame

A frame consists of exactly one sample per channel. If there is only one channel (Mono sound) a frame is simply a single sample. If the sound is stereo, each frame consists of two samples, etc.

Frame size
This is the size in bytes of each frame. This can vary a lot: if each sample
is 8 bits, and we’re handling mono sound, the frame size is one byte.

Similarly in 6 channel audio with 64 bit floating point samples, the frame size is 48 bytes

Rate

PCM sound consists of a flow of sound frames. The sound rate controls how often the current frame is replaced. For example, a rate of 8000 Hz means that a new frame is played or captured 8000 times per second.

Data rate

This is the number of bytes, which must be recorded or provided per second at a certain frame size and rate.

8000 Hz mono sound with 8 bit (1 byte) samples has a data rate of 8000 * 1 * 1 = 8 kb/s or 64kbit/s. This is typically used for telephony.

At the other end of the scale, 96000 Hz, 6 channel sound with 64 bit (8 bytes) samples has a data rate of 96000 * 6 * 8 = 4608 kb/s (almost 5 MB sound data per second)

Period

When the hardware processes data this is done in chunks of frames. The time interval between each processing (A/D or D/A conversion) is known as the period. The size of the period has direct implication on the latency of the sound input or output. For low-latency the period size should be very small, while low CPU resource usage would usually demand larger period sizes. With ALSA, the CPU utilization is not impacted much by the period size, since the kernel layer buffers multiple periods internally, so each period generates an interrupt and a memory copy, but userspace can be slower and read or write multiple periods at the same time.

Period size

This is the size of each period in Hz. Not bytes, but Hz!. In alsaaudio the period size is set directly, and it is therefore important to understand the significance of this number. If the period size is configured to for example 32, each write should contain exactly 32 frames of sound data, and each read will return either 32 frames of data or nothing at all.

Once you understand these concepts, you will be ready to use the PCM API. Read on.
