An Efficient Scheme for Lossy Real-Time Audio Data Compression
The increasing use of digital audio in personal computers indicates an ongoing need for computationally efficient audio data compression. An implementation of adaptive differential pulse-code modulation incorporating a recursively indexed quantizer (RIQ-DPCM) is presented as an alternative method for efficient audio signal compression on general-purpose computers. The performance characteristics of the RIQ-DPCM procedure are compared with other standard coding techniques of similar computational complexity, and several real-time implementation issues are discussed.
