audio = pyglet.media.load("audio.wav")
audio.play()

Working with WAV files

winsound

• Windows environment

  import winsound winsound.PlaySound(“path_to_wav_file.wav”, winsound.SND_FILENAME)

wave

• Support mono/stereo

• Doesn’t support compression/decompression

  import wave with wave.open(“path_to_wav_file.wav”, “rb”) as wav_file: # Open WAV file in read-only mode. # Get basic information. n_channels = wav_file.getnchannels() # Number of channels. (1=Mono, 2=Stereo). sample_width = wav_file.getsampwidth() # Sample width in bytes. framerate = wav_file.getframerate() # Frame rate. n_frames = wav_file.getnframes() # Number of frames. comp_type = wav_file.getcomptype() # Compression type (only supports “NONE”). comp_name = wav_file.getcompname() # Compression name.

    # Read audio data.
    frames = wav_file.readframes(n_frames)    # Read n_frames new frames.
    assert len(frames) == sample_width * n_frames

  Duplicate to a new WAV file.

  with wave.open(“path_to_new_wav_file.wav”, “wb”) as wav_file: # Open WAV file in write-only mode. # Write audio data. params = (n_channels, sample_width, framerate, n_frames, comp_type, comp_name) wav_file.setparams(params) wav_file.writeframes(frames)

Convert any soundfile with python and ffmpeg

from subprocess import check_call

ok = check_call(['ffmpeg','-i','input.mp3','output.wav'])
if ok:
    with open('output.wav', 'rb') as f:
        wav_file = f.read()

Playing Windows’ beeps

Windows provides an explicit interface through which the winsound module allows you to play raw beeps at a given frequency and duration.

import winsound
freq = 2500 # Set frequency To 2500 Hertz
dur = 1000 # Set duration To 1000 ms == 1 second
winsound.Beep(freq, dur)
