MPEG AAC LC Decoder
Advanced Audio Coding (AAC) has been standardised by ISO and IEC, as part of the MPEG-2 and MPEG-4 specifications. The low complexity audio codec (AAC-LC) provides good sound quality at low bit-rates.
The ESPICO implementations have been optimised for low memory and MHz requirements allowing low power applications to be realised. Contact ESPICO for specific resource requirements.
