I used GRIP in Linux to convert my music CDs to FLAC. I didn't realize it at the time, but I have numerous CRC mismatches in the encoded files where physical scratches were located. Normally, I don't ever notice these errors during playback in Amarok or on my Squeezebox.

Since I recently bought an iPod, I had to convert all my FLAC files to MP3 using flac and lame on the command line. These mp3 files contain silent breaks anywhere there were CRC mismatches in the flac file. The same effect occurs when I use winamp to convert FLAC to mp3 in Windows. I know it's theoretically possible to interpolate through the errors, because we are oversampling with the FLAC format (~900 kbps vs. 320 kbps). But, how can I decode through errors while interpolating to get rid of silent breaks in my music??? This must be how Amarok and Slimserver deal with errors, so why is it not an option in the flac binaries?

FLAC does not oversample. It merely doesn't throw anything away to reduce the bitrate, i.e. FLAC is lossless, MP3 is a transform codec.

Why not Rockbox your iPod to allow it to play FLAC?
