Improving Low Bit-Rate Coding

Document Thumbnail

[Feature] Despite its mature stage of development, low bit-rate audio coding continues to be improved, both in its lossy and lossless forms. Improved matching of phase parameters can help stereo coding, and the reconstruction of high-frequency content can be enhanced without excessive system delay. Lossless coding systems have also been made more efficient and faster. When considering listener preferences, linear PCM was found to win out over MP3 for sound engineers, but there was little to choose between them among musicians.
