Adding magphase to Merlin configuration.py, output dims?

[dreamk73]

In the script that extracts features for magphase, it says typically it extracts 60 mag, 45 real, and 45 imag features. I am using 48kHz audio, just like in the script. So are those numbers correct then? I wonder if there are delta or delta-delta features extracted as well? What should I put in configuration.py as the output dimension for these features?

Hi,
You need to add the deltas and delta deltas for each feature. So:

lf0: 1
dlf0: 3
mag: 60
dmag: 180
real: 45
dreal: 135
imag: 45
dimag: 135

By the way, the complete MagPhase-Merlin integration is coming soon. For now, you can follow the instructions in the MagPhase repo, and that should work.

Thanks. I appreciate you integrating it with Merlin. But I would like to work on trying it out now, if possible. I have worked on integrating other vocoders before, and it is doable.

Thanks to your info, I am now able to train acoustic models. But when I try to generate the waveforms with the script provided in demos/demo_run_for_merlin, I get this error:

ValueError: Dimension provided not compatible with file size.

I use 48000 Hz data and the dimensions to all the features are set as you said. Could it be the framelength feature? Or something else?

Hi, which script and line is throwing the error?

It seems that the files that you generated (.mag, .real, or .imag) have a wrong dimension. If you do not know how to check that, you can send some samples to me, so I can check it.

hi, when I run the code with my own data（child voice data），it always get the bug"magphase.py:352: RuntimeWarning: invalid value encountered in divide", is there anything I did wrong?

Hi @hyuezhi ,

Just to let you know, if you want to post any new issue or question in GitHub, you need to do it by creating a "New Issue" (button in the top right of the page), not by commenting an issue that is not related with yours :)
I created the "new issue" for you.
