They are in Flac format right now (I decimate/downsample them later depending on need) and I have tried the CLI tool for it to decode them and treat warnings as errors, but it reports no problems. I have looked at FFMpeg to see if it had something but I didn't find anything in their docs that looked relevant.
I've searched around for other tools and haven't found anything that suits my needs. I have a few dozen audiobooks that I purchased and I had assumed that they would be fine seeing as they were brand new and I opened the package, ripped them, then shelved them. Turns out some files have problems where audio "clips" for a second or it repeats the same chunk of audio a few times (sounds like someone stuttering) then jumps ahead by several seconds. I've never had a problem like this, and when I looked at the physical media there were a few spots that seemed to line up with where the audio would have been.
Any ideas on tools that I can use to scan all my Flac files and give me a report of which files it found problems in, hopefully at what moment it found the error?
