I'm impressed... detecting corrupted audio files

Out of curiosity, I looked at the Log output. I was surprised to see I had some missing tracks in playlists (which was easy to correct in iTunes).

And, I had some IDv3 tags that required updating - again, nice, and easy to fix with the Tag app.

More interesting, however, were the indications of audio stream corruption in some MP3s. Skeptical, I listened to the tracks so indicated and was glad to hear that, yes, in fact, each of the tracks were corrupted (I can hear skipping sounds during playback).

How accurate or reliable is this with FLAC and ALAC tracks? What I mean is, how reliably can MinimServer detect corrupted audio and/or damaged tags?

Is MinimServer my solution for detecting bit-rot on my audio collection? If so, this is really, really cool, because detection of bad audio files is now a simple case of re-rip and/or MD5 compare and restore from a back-up on my Drobo.

MinimServer isn't doing as much audio corruption detection as you are hoping for.

For some MP3 files, it is necessary to read a sample of audio frames to compute the track duration. if MinimServer detects audio corruption while doing this, it will produce the messages you have seen. In all other cases, MinimServer doesn't read or check the audio data in the file.
