Travailler avec des fichiers WAV
winsound
- Environnement Windows
import winsound
winsound.PlaySound("path_to_wav_file.wav", winsound.SND_FILENAME)
vague
- Support mono / stéréo
- Ne supporte pas la compression / décompression
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)
Convertir n'importe quel fichier son avec python et 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()

Jouer les bips de Windows
Windows fournit une interface explicite grâce à laquelle le module winsound
vous permet de jouer des signaux sonores bruts à une fréquence et une durée données.
import winsound
freq = 2500 # Set frequency To 2500 Hertz
dur = 1000 # Set duration To 1000 ms == 1 second
winsound.Beep(freq, dur)
