My reading of what you've said here suggests to me that you're proposing that the server should apply ReplayGain to the audio samples prior to sending it to the players. If I've misunderstaood what you're saying, my apologies. If however that is what you're saying, then this is absolutely, unequivocally the wrong way to do it. The audio samples *must* be sent to each player unmolested, for a variety of reasons:
1. Some players might have ReplayGain enabled, others not. Some may want to use track gain, others album gain. You can't apply the ReplayGain at the server end once for all clients. 2. The ReplayGain adjustment (which is done in the digital domain) should be applied after the signal has been widened to 24 bits within the player (in order to preserve resolution). If it's done in the server, you'd have to widen it to 24 bits, which might involve on-the-fly decoding to WAV, widening and either re-encoding back to FLAC or acceptance of increased network bandwidth requirements. 3. Some of us run SqueezeCenter on low-power servers, which may not have the CPU available to perform all this stuff at the server. 4. There may be some more reasons I've not thought of. -- cliveb Transporter -> ATC SCM100A ------------------------------------------------------------------------ cliveb's Profile: http://forums.slimdevices.com/member.php?userid=348 View this thread: http://forums.slimdevices.com/showthread.php?t=30316
