Dolby® Digital Consumer Decoder (AC-3)
The Dolby® Digital Consumer Decoder defines methods for compression /decompression of 1 to 5.1 audio channels at sample rates of 32, 44.1 or 48 kHz at bitrates from 32 to 640 kbit/s. The 0.1 channel refers to a fractional bandwidth channel intended to convey only low frequency (subwoofer) signals, the so called LFE channel.
The ESPICO implementations are based on the Dolby reference model with proprietary optimisations to reduce memory and MHz requirements. Contact ESPICO for specific resource requirements.
