The same config with paths modified for Linux works.

(edited OP post for better readability)

So it's a problem with dealing with mp3gain output. We recommend on the plugin help page to install the original mp3gain, is that what you did ? Can you confirm you use the 1.2.5 version ?

(I use this plugin but on mac with aacgain so I don't have a quick fix, sorry)

[sampsyo]

Looks like we lost the error handling for malformed mp3gain output in 86ee30df0d177f9103a7c4e7489cbf06aaa62838. I'll add that back in.

This of course doesn't address why mp3gain failed here, as @KraYmer points out—maybe more debugging output will help.

[sampsyo]

The above commit should do it. Please reopen if the problem persists.

I am running the latest aacgain for windows from http://www.rarewares.org/aac-encoders.php

[arogl]

This is indeed now working.

The other strange thing was if I ran the import again, aacgain would work..... @KraYmer what did you use to clean up my bug report?

[Kraymer]

@arogl I just indented the code with 4 spaces (syntax for preformatted text) @sampsyo if it's working, maybe we could indicate this aacgain version in the doc alongside mp3gain ?

[sampsyo]

Sure; seems worth a link.
