Digital Audio Processor Delivers Versatility And Precision

Featuring 32-bit precision, the Melody 32 digital audio processor provides a wide complement of audio formats and post-processing capabilities to enable high-volume consumer applications with recording-studio audio quality. It implements Dolby Digital, Dolby Digital EX, Dolby Pro Logic II, DTS-ES Extended Surround, DTS Neo:6, SRS Circle Surround II, THX, and THX Surround EX. The device also delivers AAC (two-channel, low complexity), MP3 (MPEG1 Audio Layer 3), PCM, and Bass and Delay Management. All are delivered with 32-bit precision on up to eight channels. The Melody 32 automatically detects the incoming bit stream and applies the appropriate code downloaded from the boot flash. To speed development time for the consumer market, the audio processor is available as a complete, fully engineered reference design. An evaluation board with an evaluation copy of the software and schematics costs $1250 in single quantities and is currently shipping to qualified customers.
