A utility that handle audio for Python.


Simple Example

import rwave
# Load audio file
wave, fs = rwave.read_wave('wave file path')

# Write audio file
# (wave file path, wave data, fs)
rwave.write_wave('wave file path', wave, 16000)

# Nomalize wave data
# => audio data normalized to 0~1

# Convert sampling rate (16000->8000)
wave, fs = rwave.convert_fs(wave, 16000, 8000)

# Convert audio length (->5.0s)
wave, fs = rwave.convert_fs(wave, 16000, 5.0)

# Convert to MFCC
mfcc = rwave.to_mfcc('wave file path', 16000)


$ pip install rwave
