This is a bit of a tough question but figured id throw it out there....I tend to work on premiere and after effects so my knoweldge with audtion and audio is pretty limited.
Im working with a mono file, that as best as i can tell was mixed from stereo to mono with a phasing issue. There is stadium noise on the sound effects track that has a phasing issue, and only at certain parts. IE its not throughout the whole scene. Ive tried multiple filters including noise reduction, phasing correction, sound removal, as well as trying to paint out this phasing sound using spectral frequency display to no avail. Nothing seems to change. Its like trying to change an effect that has already been nested within a piece of media.....and all i have to work with is the rendered out piece of media.
Just looking for any other suggestions form more experienced audition users
