Thanks for working on this!

However, no tests are running at current.

Have you tried running them at all? Of course, a few depend on sox and will fail.

You recommend making soundfile the default in windows? If that is the case, I'm thinking we may want to make soundfile the default everywhere. Since we are doing the 0.4.0 release now, it may be a good idea to bring this in now so that we have window supported.

Thoughts?

I made the change because I was not able to compile the sox backend on Windows. So actually, soundfile is the only available choice for Windows.

If that is the case, I'm thinking we may want to make soundfile the default everywhere.

The major limitation of soundfile is that it cannot read the file with the MP3 format, which is possible in sox.

Another difficulty I met is that there are no available pysoundfile packages hosted on Anaconda Cloud for Windows. Although the current one is marked as noarch, it is depending on a gcc package which is not available on Windows. So for conda users, the installation script will look a bit weird like this.

conda install -c pytorch torchaudio
pip install soundfile

Thanks for doing this! Since sox is not an option on windows, we'll fall back to soundfile as you suggest.
