Play audio with Python

Question

How can I play audio  it would be like a 1 second sound  from a Python script   It would be best if it was platform independent  but firstly it needs to work on a Mac   I know I could just execute the afplay file mp3 command from within Python  but is it possible to do it in raw Python  I would also be better if it didn t rely on external libraries

In pydub we ve recently opted to use ffplay  via subprocess  from the ffmpeg suite of tools  which internally uses SDL   It works for our purposes     mainly just making it easier to test the results of pydub code in interactive mode     but it has it s downsides  like causing a new program to appear in the dock on mac   I ve linked the implementation above  but a simplified version follows   import subprocess  def play audio file path       subprocess call   ffplay    -nodisp    -autoexit   audio file path     The -nodisp flag stops ffplay from showing a new window  and the -autoexit flag causes ffplay to exit and return a status code when the audio file is done playing   edit  pydub now uses pyaudio for playback when it s installed and falls back to ffplay to avoid the downsides I mentioned  The link above shows that implementation as well

Try PySoundCard which uses PortAudio for playback which is available on many platforms  In addition  it recognizes  professional  sound devices with lots of channels   Here a small example from the Readme   from pysoundcard import Stream     Loop back five seconds of audio data      fs   44100 blocksize   16 s   Stream samplerate fs  blocksize blocksize  s start   for n in range int fs 5 blocksize        s write s read blocksize   s stop

Sorry for the late reply  but I think this is a good place to advertise my library      AFAIK  the standard library has only one module for playing audio  ossaudiodev  Sadly  this only works on Linux and FreeBSD   UPDATE  There is also winsound  but obviously this is also platform-specific   For something more platform-independent  you ll need to use an external library   My recommendation is the sounddevice module  but beware  I m the author    The package includes the pre-compiled PortAudio library for Mac OS X and Windows  and can be easily installed with   pip install sounddevice --user   It can play back sound from NumPy arrays  but it can also use plain Python buffers  if NumPy is not available    To play back a NumPy array  that s all you need  assuming that the audio data has a sampling frequency of 44100 Hz    import sounddevice as sd sd play myarray  44100    For more details  have a look at the documentation   It cannot read write sound files  you ll need a separate library for that
