Cyberbiz Brief

Three companies said they have developed a way to send near-CD-quality sound over slower wireless connections in a way that consumes relatively little power. The technology could give a big boost to companies distributing music and audio to cellphones and wireless and portable devices, improving sound quality while lengthening battery life. It could be particularly important as part of development of entertainment products on next-generation cellphone networks.

The technology is a decoder based on aacPlus, the most recent update to the audio portion of the MPEG-4 compression standard for digital media. Decoder was developed by Coding Technologies, Matsushita Electric Industrial Corp. and NEC.
