[solved] tool for copying lossy and recode losseless audio files

Hallo,
I'm looking for a tool for copying recursively audio files of different formats to another folder, e.g. on a SD card, but recoding all losseless formats (e.g. flac) and just copy files which are already converted to a lossy format (ogg, mp3).  Preferably something like rsync for copying only modified files but recoding losseless formats.  Does anyone has an suggestion?

Re: [solved] tool for copying lossy and recode losseless audio files

You're describing 2 steps in there it seems.  For simply copying of lossy, use rsync with the --exclude flag to not process the .flac files.  For them, use a util like flac2all (https://aur.archlinux.org/packages/flac2all/) then copy them over.  Might be easier to reverse those steps, 1) make all mp3 or whatever, then rysnc.

OK, thank you for pointing me to flac2all.  Indeed, it shouldn't be too complicated to craft a script for this job.  But I'm still suprized, that ther exist no ready-made tool for such a common job.

I might be out of the loop here, but does re-encoding lossy formats actually gain anything? doesn't it just leave you with a larger output file of the same (or slightly worse due to re-encoding) quality as the input file?

No, it doesn't gain anything.

But your the first person in this thread to mention re-encoding lossy formats.

No, it didn't "fix" anything. It just shifted the brokeness one space to the right. - jasonwryan

After playing around with flac2all I found the swithches -c for copying all non flac files and -x for excluding with an regular expression.  This is the tool I was looking for.
