Adaptive Cross-Correlation Compression Method in Lossless Audio Streaming Compression

Lossless Compression of Audio Data

Lossless data compression of digital audio signals is useful when it is necessary to minimize the storage space or transmission bandwidth of audio data while still maintaining archival quality. Available techniques for lossless audio compression, or lossless audio packing, generally employ an adaptive waveform predictor with a variable-rate entropy coding of the residual, such as Huffman or Gol...

Lossless Audio Compression: A Case Study

Audio compression is used everywhere – largely due to the rise of the internet, computers, and embedded systems. Since original, uncompressed digital recordings are very large in size, efficient ways are needed to compress large audio signals into small, high-quality, convenient formats. While lossy audio formats, like MP3, are widely popular in many everyday applications, lossless formats are ...

A Scalable to Lossless Audio Compression Scheme

This paper outlines a scalable to lossless coder, that is the coder presented is a scalable coder that scales from lossy quality to lossless quality. Lossless compression is achieved by concatenating a lossy, scalable transform coder with a scalable scheme for the compression of the synthesis error signal. The lossless compression results obtained are comparable with the state of the art in los...

Integer Wavelet Transform Based Lossless Audio Compression

In this paper we propose the use of integer wavelet [2] as a decorrelation stage for adaptive context based lossless audio coding. The original wideband audio signal is first decomposed in wavelet subbands. The resulted coefficients are integer valued and therefore can be transmitted using an adaptive context based method, in a lossless manner, the decoder being able to reconstruct them and aft...
