Multitrack support #122

Closed bmcfee closed 9 years ago

bmcfee commented 9 years ago

The current loader has an option to convert stereo to mono, assuming interleaving of two channels. This could be generalized to support general mixing of multi-tracks by using the frame function.

I don't think there are many multitracks that appear as n-channel wav files. The ones I've seen are collections of individual sound files, as well as MOGGs, which I believe is just a container around multiple independent OGGs.

But I haven't looked at the new data from NYU.

DAn.

Yeah, you're right. Disregard this issue.

@bmcfee I could extract a stereo track in multitrack using librosa, but I would like the multitrack to be unfiltered.

lostanlen commented 1 year ago

@romino666 if by unfiltered you mean non-resampled, consider passing sr=None
