I added a feature to support resampling of audio arrays to a 16 kHz sample rate

Mm could we instead use torchaudio for the resampling since this will use available backend (soundfile or sox flexibly etc.)

Yes, I just tested torchaudio, and it works correctly. I am addressing some bugs I found while adding support for 1D and 2D audio and different dtypes.

Resample audio arrays using torchaudio, taking advantage of its availability on the backend.

This function has been tested with arrays from the following libraries: torchaudio, librosa, scipy, and soundfile.

It has been tested with the following files:
- 'mono_int16_44kHz.wav'
- 'mono_int32_44kHz.wav'
- 'mono_float32_44kHz.wav'
- 'mono_float64_44kHz.wav'
- 'stereo_int16_44kHz.wav'
- 'stereo_int32_44kHz.wav'
- 'stereo_float32_44kHz.wav'
- 'stereo_float64_44kHz.wav'
- 'stereo_int16_8kHz.wav'
- 'stereo_int32_8kHz.wav'
- 'stereo_float32_8kHz.wav'
- 'stereo_float64_8kHz.wav'
- 'mono_int16_8kHz.wav'
- 'mono_int32_8kHz.wav'
- 'mono_float32_8kHz.wav'
- 'mono_float64_8kHz.wav'

@m-bain now works with torchaudio. Has been tested with arrays from torchaudio, librosa, scipy, soundfile and with the files:

  • 'mono_int16_44kHz.wav'
  • 'mono_int32_44kHz.wav'
  • 'mono_float32_44kHz.wav'
  • 'mono_float64_44kHz.wav'
  • 'stereo_int16_44kHz.wav'
  • 'stereo_int32_44kHz.wav'
  • 'stereo_float32_44kHz.wav'
  • 'stereo_float64_44kHz.wav'
  • 'stereo_int16_8kHz.wav'
  • 'stereo_int32_8kHz.wav'
  • 'stereo_float32_8kHz.wav'
  • 'stereo_float64_8kHz.wav'
  • 'mono_int16_8kHz.wav'
  • 'mono_int32_8kHz.wav'
  • 'mono_float32_8kHz.wav'
  • 'mono_float64_8kHz.wav'
