Fixing broken recordings

Hello, I’ve been doing a recording of a concert recently, but somehow i probably closed supercollider the wrong way and now I have a 700Mb .aiff file, but am unable to listen to it.
Im guessing the most important data is available. I’ve been simple recording with the internal supercollider recording options.
Im using (arch) linux. Is there any way of fixing such files, does anyone experience something similiar? Thank you very much!

You can use audacity to fix these kinds of things. Can’t remember how off the top of my head, but search for audacity and corrupt headers or something like that, and you should be able to recover your work.
