BUG with dbpoweramp 2025-12-04

[ozzyan]

In-place FLAC to FLAC conversion (overwrite) with Multi-CPU enabled mis-pairs source and destination files.
Issue disappears completely when Multi-CPU is disabled.
Causes cross-album overwrite attempts (Win:1460).
Previous versions did not exhibit this behavior.
Example from the error log:

How many files are you converting? what is your exact naming string? if you list the files on the music converter options page before converting, where choose flac (not in batch converter), does it list them right?

What DSPs are you using?

[PeterP]

Also what kind of a volume are you converting to? Is M: a mapped network drive?

[PeterP]

Using Conditional Encoding by any chance?

[ozzyan]

No, nothing complicated or special about it — a pure FLAC to FLAC overwrite. An internal drive, no DSP. It’s a huge batch job, around 3–4 TB. Every time a new version of the FLAC encoder comes out, I re-encode the entire collection. I’ve been through this many times and never had an issue like this before. I have backups of all files prior to conversion, and when I run test conversion on the old files, no errors are reported. However, during conversion with the new dBpoweramp, what I described happens - it attempts to overwrite the wrong files. Not all of them, but some, like in the example given.

Thanks for the details.
Attempted fix-

https://www.dbpoweramp.com/beta/2025-12-18/MusicConverter.exe

Please overwrite MusicConverter.exe from in your Program Files/dBpoweramp folder and retry problematic conversion.
