Thanks for the update, Yes, I may have to use ALAC over FLAC, since that's the only way I can get them to a playlist on the iPad. FLAC won't copy. I guess for most live situations it doesn't matter. The higher frequencies lost in "lossy" format are probably not discernible to anyone anyway. I'm probably splitting hairs over nothing. If I was building a track in my DAW from scratch, I would probably use ALAC, but most of the tracks are already MP3 and I've already lost the higher frequencies anyway. My real concern is the more you keep compressing in "lossy" format, you eventually start degrading the audio. When I master, I take an existing MP3 track, add some console emulation (N-type) to it and some compression, normalize it and export it. I will give your suggestion of AAC with 320kbps a try which should suffice for live applications. FYI, LouderLogic can't play ALAC files although the iPad player can.
