Gammatone

✓ from gammatone import Gammatone

✗ from gammatone.gammatone_impl import Gammatone

Create a gammatone-based cochleagram from an audio signal.

import numpy as np from gammatone.gtgram import gtgram # Generate a cochleagram from a sample audio signal fs = 16000 duration = 0.1 t = np.linspace(0, duration, int(fs*duration), endpoint=False) signal = np.sin(2*np.pi*1000*t) # 1 kHz tone # Compute gammatone spectrogram (cochleagram) coch = gtgram(signal, fs, window_time=0.02, hop_time=0.01, channels=64, f_min=50, f_max=8000) print(coch.shape)

Debug

Known issues

gotchaThe default f_max in gtgram is 4000 Hz. If you need higher frequencies (e.g., for 22050 Hz audio), pass f_max explicitly. Added in v1.0.3.

fix

Call gtgram(... , f_max=8000) to extend coverage.

affects: <1.0.3

gotchaInput signal must be 1-D array. If you pass a 2-D array (e.g., stereo audio), it will fail silently or produce incorrect shape.

fix

Mono mix: signal = np.mean(signal, axis=1) for stereo.

affects: all

deprecatedDirect import from gammatone.gammatone (without _impl suffix) may be deprecated in future releases. Use gammatone.gammatone_impl for core filter classes.

fix

Use from gammatone.gammatone_impl import Gammatone

affects: >=1.0.0
