Loading sph audio files

Can audio.load load NIST sphere format (SPH) files?

Hi!

So I have tried to load sph files from tedlium dataset with simply:

torchaudio.load("pathtofile")

The load was successful but when saving it to a .wav file to check if the torchaudio read correctly the audio then I realized it was not working.

My question then is if this type of audio files is currently supported by torchaudio and if so, could you provide some link/code that refers how to? I haven’t been able to find anything about torchaudio and sph files (but I know sox supports sph and allows to conversion into wav)

In case someone needs sph files here there are some sample ones https://filesamples.com/formats/sph. I got mines from the TEDLIUM dataset.

Thanks

@jiwidi Thanks, and you are working on torchaudio master branch, right?

I added support for sph format in "sox_io" backend. Can you try my branch mthrok/sph or cherry pick this commit https://github.com/mthrok/audio/commit/f78ebf9556cf237de9e2fb8b3b156dca90769435 and try "sox_io" backend?

import torchaudio
torchaudio.set_audio_backend("sox_io")
wave, sample = torchaudio.load("sample1.sph")
torchaudio.save("sample1.wav", wave, sample)

I believe this works, and if you can confirm I will merge it to master branch.

@jiwidi Thanks for confirming. I merged the commit to master.
