Audio compressor which uses (4,2) CDF wavelet
This package is a proof of concept of wavelet transform-based lossless
audio codec. wavelet-audio uses (4,2) B-spline wavelet and Rice
entropy coding to compress audio. Compression speed is slow,
decompression speed is much faster.
Compression ratio is 25-50% and is comparable to ratio of flac codec.
