I'm getting the same issue with the sound: speech is intelligible but with a strong warble that makes it sound like talking through a fan.  I had a quick look at the waveform and spectrum of the output but didn't spot any obvious problems there.  Not knowing IMBE, I couldn't get far with the code.  Any ideas?
