Whitepaper: Reducing The Complexity Of Sub-band ADPCM Coding

by APTXFeb 01, 2009

The number of consumer audio applications demanding high-quality audio compression and communication across wireless networks continues to grow. Although the consumer is increasingly demanding higher audio quality, devices such as portable media players and wireless headsets also demand low computational complexity, low power dissipation, and practical transmission bit-rates to help conserve battery life. This paper discusses research undertaken to lower the complexity of existing high-quality sub-band ADPCM coding schemes to better satisfy these conflicting criteria.


Whitepaper: apt-X Lossless For Lossless Audio Compression

by APTXJan 01, 2009

This technology white paper introduces a new scheme for lossless audio compression called apt-X Lossless. This scheme has been conceived, designed, and developed by APTX, an audio processing technology company, the commercial originator of the apt-X low-latency audio codec, and a company with a long association with both the broadcast industry and the studio post-production business.
