Is there a way to increase the pitch of the audio output in realtime?

I'm using realtimetts with kokoro and the voices sound nice but, I'm hoping to make some small adjustments by increasing/decreasing the pitch. Anyone have any ideas on how to make that work?

One idea would be to implement rubberband in KokoroEngine, right before the final wave gets putted into the (output) queue.

I used pyrubberband to shift the pitch before the audio wave was converted into an int16 format and fed into the queue in KokoroEngine.py and it worked. Thank you so much for the insight!

Great to hear it worked.
