LossyWAV is a new free lossy pre-processor for PCM audio contained in the WAV file format. It reduces bit depth of the input signal, which, when used in conjunction with certain Lossless codecs, reduces the bitrate of the encoded file significantly compared to unpreprocessed compression. lossyWAV's primary goal is to maintain transparency with a high degree of confidence when processing any audio data.
LossyWAV is a very new audio processor (no official release as of 2008-01-23) and as such there has not been widespread testing. Thus, use with caution and for testing purposes only.
