16k sample rate audio error

[zhang-jian]

Sorry if this question is too naive.

Can I use this tool on 16k sample rate audios? I am trying to run the demo code on a 16k sample rate audio and got error

Yes, MagPhase can work with 16kHz audios. If you look at src/magphase.py, you will find it supports 16000, 22050, 44100, 48000 sample frequency. Parameters need to be tuned if synthesized quality sounds dramatically poor.
