I've messed a bit with MP3 and am contemplating tranferring all my CDs to an HTPC via lossless compression (e.g. FLAC) or as .wavs, to create a jukebox that I;d connect to my AV receiver, but something's still unclear. I'd like to keep the signal digital all the way into my receiver which can then do digital-based stuff like bass management and DPL II processing. My receiver can decode MP3 but not other compression formats. So I presume decoding has to be done in my computer for FLAC files. Does this *also* mean that the signal is converted to analog before being sent to my receiver? Or can a FLAC track be decoded and sent to my AVR's digital (e.g. optical) input without having gone through a D/A conversion? If so, is it sent as a 'bitstream', or what? And is there any way to do this *wirelessly*? One last question: I'm familiar with ID3 tags and software that reads them in order to present track info and such for MP3s. How is this done for libraries of native .wav files? I'd want to be able to select tracks on my PC for playback on the HT system. ..so there has to be some way to grab track info and associate it permanently with the .wav file. AFAIK .wav files do not have 'built in' tags a la MP3s...or do they?
