Hello! I'm trying to implement AAC decoder on Atmel AVR32 UC3A. I've got problem with very long decoding time of one frame:( Trying with two types of decoders Helix AAC and libfaad. Here are the speed results: Helix 22050hz ~5ms Helix 44100hz(with SBR) ~270ms FAAD 22050hz ~20ms FAAD 44100hz(with SBR) ~150ms Someone know how to boost up these decoder??
