Batch audio processing

[DandyLyons]

I would like to be able to open multiple audio files for processing (either selecting multiple files or selecting a directory).

When multiple files are selected, a queue UI appears and each audio will be processed sequentially with the same settings applied.

P.S. If you are interested in adding this feature, then I am interested in assisting on a PR.

Just tested today and this is already possible if you select a lot of files and drag-n-drop them onto the StemRoller window, but it looks like I forgot to add enable multi-select for the "select a local file" link inside the app. I'll try to remember to add that on the next release - shouldn't be difficult but I'm delaying to avoid pushing a 2gb update just for that feature. Thanks for bringing this issue to my attention! Please let me know if for some reason drag-n-dropping multiple files is not working for you, as that would be indicative of a bigger problem.

I tried it earlier today, and couldn't seem to get it working. But something looking like batch processing UI did come up so maybe it's just user error on my part. I'll try it again and send an update. Thank you!

I'm using macOS 15.3.1,
Stemroller latest version, just downloaded from the site yesterday.

When I click the "select a local file" button, the macOS file picker appears and does not allow me to pick multiple files or a directory. Only one audio file can be picked.

When I drag multiple files onto Stemroller, the app correctly shows UI saying that I can drop "file(s)" onto the UI. However, the results are inconsistent. In this example, only the 1st and 3rd file actually got processed and the UI said that only the 2nd and 3rd got processed.

Each time I run the exact same process, I get different results. So it seems like there might be a race condition somewhere.

Good to know - thanks for reporting! I'll try to fix this next time I'm working on StemRoller.
