Where to find "Apply Chain" files? [SOLVED]

I’m new to Audacity, so forgive me if this is an obvious question, but:

I’m trying to change the pitch of a couple dozen MP3 files by -20%, so I did what the Internet told me to and made a chain, with ChangePitch Percentage=“-20.000000000000”. I then clicked “Apply Chain…”, then “Apply to Files…”, then Audacity started chugging away like normal. But when it finished, the changed files were nowhere to be found! The manual says it should be in a folder named “cleaned”, but there’s no such folder, and the original files weren’t changed either.

So where are the finished files located after you run “Apply Chain”? Is this a bug, or am I missing something obvious?

I’m using Audacity 2.1.1 on Mac OS X 10.11.2.

When applying a Chain to files, the exported files will be saved in a folder named “cleaned” in the same folder that the original files came from. The original files are not changed.

See http://manual.audacityteam.org/o/man/apply_chain.html#apply.


That’s what’s supposed to happen, but the “cleaned” folder is nowhere to be found for me. How can I fix this?

in the same folder that the original files came from.

Where did the original files come from? Desktop? My Music? If Audacity experiences a permissions issue (I’m not allowed to write files here) chains will fail.

You can also have very energetic virus protection that’s eating your new files as they’re created.

One way to reveal shenanigans is do one cycle of the chain manually. Manually create a “cleaned” folder and manually process one file and export it to the cleaned folder. Could you do it without problems? Were there any extra “OK” steps needed in there? Chains will not roll over those.


The original files are just in a folder in my Downloads folder, which should have no problems with permissions. And I have no antivirus software on my Mac, so that shouldn’t be a problem either.

I have a question—in the chain itself, I have it set up like this:

01 ChangePitch Percentage=“-20.000000000000”
02 -END-

You mentioned something about exporting. Should I have had something like “ExportMP3” in the chain too?

As it says on http://manual.audacityteam.org/o/man/apply_chain.html, for applying Chains to files the selected Chain must include an “export” step, or the processed audio will not be saved.


I now added the “ExportMP3” step, and now the “cleaned” folder is appearing! I can’t believe I missed something so obvious.
But now, the resulting audio files in the “cleaned” folder don’t have the -20% pitch change; instead, they’re identical to the original files. Do you know what could be causing this?

Perhaps you have the Chain items in the wrong order. The Export step must be the last step before “- END -”

That seems to have been the problem, thanks. Sorry for putting you through all this :stuck_out_tongue:
