Flac network streaming is tricky because of the way flac handles silence in audio, but it can be worked around with a few lines changed in libflac. I've recently developed some of the only software I know of that lets you simply stream native flac from computer to computer, up to 8 channels. Its st

Brian... You've been both polite and helpful. Thanks. I do understand the dimensional nature of images and sound, though I admittedly glossed over the details while trying to draw attention to time rather than spatial artifacts. What I was looking for was confirmation that a properly designed

My question is based on temporal considerations. Given a WAV file converted to FLAC and then decoded to WAV, is it possible for artifacts to be introduced? I've been told that FLAC files, when played back into a high-quality sound system, fail to properly reproduce certain kinds of sounds, like

I'm well aware how compression works. But images and document files do not depend on the relative timing of the data to reproduce themselves. They are in essence only two-dimensional in space, whereas the data in a sound file is time-dependent. The question really has more to do with the decod

FLAC is variable bitrate, but the bitrate is determined by how efficiently the data can be compressed while maintaining 100% data integrity. On Mon, May 23, 2011 at 1:26 PM, Dennis Brunnenmeyer wrote: > Is FLAC a variable bit rate format when streamed? If so, how can it be truly > lossless? > --
