Can I load a wav file without JAMS? #63

Hi:

I would like to do data-augmentation for my bunch of wav files. Can I use MUDA without JAMS file? Thanks!

MUDA uses jams for the underlying data structure to store parameters, so no. But, you can always make an empty jams object at load time, run it through MUDA, and discard the jams at the end.

You probably should keep the output jams though, as it contains all the history of how the augmentation was performed.

Note to self: we should add an example of this to the documentation.

Glad to hear that an empty JAMS is a solution. Expecting to see the example code since I still have no ideal how to do it. Thanks for the reply!

It turns out this is so simple. (Sorry I'm a rookie in this)

import muda
import jams

j_orig = muda.load_jam_audio(jams.JAMS(), 'some.wav')
