Python Wave Module
The wave module provides a convenient interface to the WAV sound format. It does not support compression/decompression, but it does support mono/stereo.
Importing the Module
import waveReading WAV Files
To read a WAV file, use wave.open() with mode 'rb'.
import wave
try:
with wave.open('sample.wav', 'rb') as f:
print("Channels:", f.getnchannels())
print("Sample width:", f.getsampwidth())
print("Frame rate:", f.getframerate())
print("Number of frames:", f.getnframes())
print("Parameters:", f.getparams())
except FileNotFoundError:
print("File not found.")
except wave.Error as e:
print(f"An error occurred: {e}")Writing WAV Files
To write a WAV file, use wave.open() with mode 'wb'.
import wave
# Parameters: (nchannels, sampwidth, framerate, nframes, comptype, compname)
nchannels = 1
sampwidth = 2
framerate = 44100
with wave.open('output.wav', 'wb') as f:
f.setnchannels(nchannels)
f.setsampwidth(sampwidth)
f.setframerate(framerate)
# Write dummy frames (silence)
# 2 bytes per sample * 1 channel * 100 frames
data = b'\x00\x00' * 100
f.writeframes(data)
