Where is the Complex Modulus function in the MFCC implementation?

[Good Robot]

Hello,

As I am trying to verify my calculations with the librosa model. I am missing the point where the complex modulus is applied?  According to the block diagram:

where in the librosa code does that Modulus block come into play?  I looked at your source code but could not figure out at which point you apply the modulus function.  Can you point me as to where in your code this occurs?

Thanks for your time and help!

This is done inside the _spectrogram() helper function called from melspectrogram.

Hello,

Is it this that is considered the Complex Modulus?

Thanks!
