RuntimeError: torchaudio.sox_effects.sox_effects.apply_effects_tensor requires sox extension, but TorchAudio is not compiled with it. Please build TorchAudio with libsox support.

It seems to work correctly after patching the apply_effects_tensor method since reverse is the only effect used but probably not the most elegant solution.

torchaudio.sox_effects.apply_effects_tensor = lambda waveform, sample_rate, _: (
    torch.flip(waveform, (-1,)),
    sample_rate,
)

I have pushed a fix which implements roughly this. The sox apply_effects_tensor is no longer used and so it might work better on windows now. However certain training functions will likely still not work on windows.
