Low Delay Advanced Audio Coding (AAC-LD) is the high-quality low-delay audio coding standard within MPEG-4. The MPEG-4 Low Delay Audio Coder is designed to combine the advantages of perceptual audio coding with the low delay necessary for two-way communication. It has achieved wide acceptance in high end video conference terminals and is used ...

The audio quality of AAC-LD and AAC-ELD is superior to ITU-T G.722/G.722.1-C at identical bit rates. A structural comparison with the ITU-T pendant G.722.1-C (Siren 14) is discussed in the AES paper »MPEG-4 Enhanced Low Delay AAC - A new Standard for High Quality Communication« and is available on request.

20 ms figure of AAC-LD is lower than the latency of most modern speech codec standards. The only draw-back of AAC-LD is the somewhat higher data rate re-quired when compared to modern speech coders. Re-cently, however, ISO has published a new amendment to MPEG-4 Audio which standardizes an enhanced version of AAC-LD, called Enhanced AAC-LD ...

Additional AAC technologies covered by the patent license include AAC-LD (Low Delay), AAC-ELD (Enhanced Low Delay) and AAC-ELD v2, which enable high quality audio for videoconferencing or other communications applications where low-latency performance is critical.
Advanced Audio Coding - Wikipedia
https://en.wikipedia.org/wiki/Advanced_Audio_Coding
Advanced Audio Coding (AAC) is an audio coding standard for lossy digital audio compression.Designed to be the successor of the MP3 format, AAC generally achieves higher sound quality than MP3 encoders at the same bit rate.. AAC has been standardized by ISO and IEC as part of the MPEG-2 and MPEG-4 specifications. Part of AAC, HE-AAC ("AAC+"), is part of …
