OK, that makes sense. I wonder what caused the problem. Is there a way to recover the files without ripping them again?
would be the easiest way.
Done on a case by case basis, it's possible, although in some cases... Bach's Brandenburg concertos have six movements, most with three section (on has two, forget which one). Call it 17 files will need to be brought into Audacity, and exported back out. Audacity can do some batch work, but, generally, this is close to a "don't raise the bridge, lower the water to let the boat through" solution. There's nothing less complex?
If the files' stats are wrong, how to choose which number is right, and adjust the other number?
This is no recommendation - but xmediarecode has a batch mode.
I think that the internet is full of wav converters.
dbPoweramp converter has a batch mode that can do wav to wav, or most other formats as well.
One thing and another, based on the above, brought me to my collection of utilities. Hmmm... what happens if... Works like a charm! It's wicked fast, andcopes nicely with "but there's already a file with that name". It tacks "-Unknown" at the back of the newly written duplicate. One caveat - any comments in the source file are replaced with fre:ac;s name and rev. number. I just did some work on some nouveau flamenco by Ottmar Liebert - part of Nouveau Flamenco was fine, 4-5 files weren't. (Why is that??). A pass through fre:ac and all is well.
Speaking of batch processing, fre:ac works best with batches. The input process uses the standard Windows Explorer window - pick one or many files & hit open. Supply a destination folder, hit the play button, and SHAZAM! all done. Of course MP3tag very nicely lets the clump of new files come up to speed in a hurry. Easy-peasy.
