AAC uses only a modified discrete cosine transform (MDCT) algorithm, giving it higher compression efficiency than MP3, which uses a hybrid coding algorithm that is part MDCT and part FFT. Tests of MPEG-4 audio have shown that AAC meets the requirements referred to as 'transparent' for the ITU at 128В kbit/s for stereo, and 320В kbit/s for 5.1 audio. The quality for stereo is satisfactory to modest requirements at 96В kbit/s in joint stereo mode however, hi-fi transparency demands data rates of at least 128В kbit/s ( VBR). Part of AAC, HE-AAC ('AAC+'), is part of MPEG-4 Audio and is adopted into digital radio standards DAB+ and Digital Radio Mondiale, and mobile television standards DVB-H and ATSC-M/H.ДЄAC supports inclusion of 48 full- bandwidth (up to 96В kHz) audio channels in one stream plus 16 low frequency effects ( LFE, limited to 120В Hz) channels, up to 16 'coupling' or dialog channels, and up to 16 data streams.

ДЄAC has been standardized by ISO and IEC as part of the MPEG-2 and MPEG-4 specifications. Designed to be the successor of the MP3 format, AAC generally achieved higher sound quality than 20th century MP3 encoders at the same bit rate.
