PEAQ is not always perfectly predictive of human listening tests.
The difference between low and full complexity is primarily the long
term predictor. PEAQ gives lower marks to the LTP than human listeners

Speech and other highly tonal signals.

Improved speech quality at low-bitrates.

No. It performs worse with loss.
