Another Spectrogram

I could use some help with my Spectrogram plugin.

Everything builds fine, but it seems like the processor buffer has 0 samples after using it in audacity.

Any ideas?

If the buffer in the plugins processBlock is always size 0, then something isn’t setup correctly with the host/system.
If your spectrogram processor has a buffer of size 0, then there’s a bug somewhere in your code. I’d start with making sure the buffer from the processBlock is being passed to any additional processors correctly.
Without any additional information, that’s the best I can give you. It’s very hard to debug with so little to work with. It’s kind of like saying “I need help finding a house, its somewhere in England, any ideas?”
