It is not invertible at the moment same as the Mel-spectrogram.

@tasercake attempted to implement the invertible Mel-spectrogram previously, but it took longer than libraosa to converge. https://github.com/KinWaiCheuk/nnAudio/issues/57

Knowing how to do invertible Mel-spectrogram should make it trivial to implement the same on the gammatone, since the only differences between them is the filter banks.

@tasercake, are you still interested in implementing the invertible Mel-spectrogram?

I'd be interested in taking another crack at it, but thus far I haven't come across any new information that would help me build a better inversion algorithm.
