On some audio tracks, when I apply the multiband compressor, stereo tracks sound mono even thought the tracks are panned left and right. When I remove the filter the tracks return to sounding stereo. Any fixes?

Of course I render everything, and all drives are less than 60% full.

are you using soundtrack or fcp compressor?

fcp:
hmm a compressor on a track squeezes the dynamic range of a sound or sounds. to a certain degree it basically isolates that sound so that it is not bothered by frequencies higher or lower than the most prevalent sound.
often time when you engage a compressor you loose ambience which can make the track seem less stereo.
i also think that compression filters are over used.

with that said, do you really need this track to be isolated?
have you tried this compression in sound track?

You can also double the track and nudge one of them slightly forward or back then pan one completely left and the other completely right. Thats the old fashion way of creating stereo.

Its the "apple" multiband compressor.

I don't want to use the compressor in Soundtrack because of it takes longer to apply it.

I don't need to create stereo, the tracks are stereo to begin with.

It's the audio filter that is making them mono.

i guess the compressor is mono, which is pretty lame

this is a guess,
try un-stereo-ing the tracks first (select, and Option L)
they should sill be panned left and right, but they now are 2 separate tracks

then apply a compressor to each track.

or maybe try trashing your prefs and see if that fixes things

Geez man! I've no idea why you'll wanna use the FCP audio filters, when you have Logic Pro plug-ins in Stkpro. They're priceless!

Deadlines loom. Sometimes saving time is more critical than quality.

I roger that. What kind of project is it? Music Video, Drama or a Documentary? Doing proper audio post mixing was pretty impossible on my previous time schedule, so what I used to do was to export the dialogue only and compress them in Stkpro (to tame the dynamic range a bit), then pump the dialogue back into Final Cut and mix the music back in. That way, i can also touch up certain scenes with audio problems (denoise, eq, etc), since the dialogue is separate from the music. Why? because i can't stand the native audio tools in final cut- there aren't flashing meters or graphs to tell you what you are doing to the audio, and the parameters look weird (i've never seen a compressor that operates on a scale of 1-100)
