Acoustica Mp3 Audio Mixer Code Details
Advanced Audio Coding is designed to be the successor of the MPEG-1 Audio Layer 3, known as MP3 format, which was specified by ISO/IEC in 11172-3 (MPEG-1 Audio) and 13818-3 (MPEG-2 Audio).
Blind tests show that AAC demonstrates greater sound quality and transparency than MP3 for files coded at the same bit rate.Improvements include:More sample frequencies (from 8 to 96 kHz) than MP3 (16 to 48 kHz)Up to 48 channels (MP3 supports up to two channels in MPEG-1 mode and up to 5.1 channels in MPEG-2 mode)
Arbitrary bit-rates and variable frame length. Standardized constant bit rate with bit reservoir.
Higher efficiency and simpler filterbank (rather than MP3's hybrid coding, AAC uses a pure MDCT)
Higher coding efficiency for stationary signals (AAC uses a blocksize of 1024 or 960 samples, allowing more efficient coding than MP3's 576 sample blocks)Higher coding accuracy for transient signals (AAC uses a blocksize of 128 or 120 samples, allowing more accurate coding than MP3's 192 sample blocks)
Can use Kaiser-Bessel derived window function to eliminate spectral leakage at the expense of widening the main lobe Much better handling of audio frequencies above 16 kHz
