Hi, I've recently gotten into lossless quality flac files. I'm going to run an extremely high end audio setup at home and I'm going to run my MBP as a music server sometimes. Is there a program that would verify if audio files are in fact lossless quality? In other words, it would check the freq. range etc. and verify if they are lossless quality. The files came as flac files but that doesn't mean the source was a cd. They could also have been HQ MP3s converted into Flac format. Any idea?
