ALAC support on Windows

[axeldelafosse]

Hey,

Hope you are doing well.

I built a script to create Traktor stems called Stemgen. It is based on ni-stem and it creates MP4 audio files using ALAC or AAC. But Traktor can't read ALAC stems on Windows. And it really is a shame to be forced to encode lossy audio files to be able to use stems on Windows.

I haven't been able to test this hypothesis yet but I think that this issue is coming from this library.

More context in the forum and on GitHub.

Can you confirm this hypothesis? Happy to help and send a PR if that's the case :)
