Sparse Modeling for Lossless Audio Compression
IEEE Transactions on Audio, Speech, and Language Processing, 2013We investigate the problem of sparse modeling for predictive coding and introduce an efficient algorithm for computing sparse stereo linear predictors for lossless audio compression. Sparse linear predictive coding offers both improved compression and reduction of decoding complexity compared with non-sparse linear predictive coding.

The development of a circuit for the compression of digital audio
IEEE Transactions on Consumer Electronics, 1993A circuit for the compression of digital audio has been developed which is very small in scale (less than 4000 gates) but exhibits nearly the same quality at 220.5 kb/s as the 705.6 kb/s 16 b PCM (pulse-code-modulated) sound. The proposed method improves the conventional ADPCM (adaptive differential pulse code modulation) coding method.

Lossless compression of one-bit audio
2004 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2004The paper introduces the coding technique that is used by the Super Audio CD system for lossless compression of 64 times oversampled one-bit audio data. The technique has been coined "DST" (direct stream transfer). The individual steps in the encoding and decoding process are detailed.

Effects of Audio Compression on Chord Recognition
2014Feature analysis of audio compression is necessary to achieve high accuracy in musical content recognition and content-based music information retrieval (MIR). Bit rate differences are expected to adversely affect musical content analysis and content-based MIR results because the frequency response might be changed by the encoding.
