When I run from_file on data/test_audio.wav I get the error:

IndexError: too many indices for tensor of dimension 1

Since the signal that gets loaded only has one dimension. Is this a data issue or is the code handling the situation incorrectly?

i thought i checked two types of files. but this is where tensor shapes on different channel data can be different. if you simply load it what does the shape look like?

i would change that to:

if len(signal.shape) > 1 and ...
    ...
else:
    signal = signal[:, None]

That audio looks like this:

It was a mono 44khz audio I recorded in audacity.

I can make the change
