Default How so I deal with strange interaction between audio tracks?

I've just run into something I've never encountered before. I've got this
big orchestral multitrack project going and in this one little spot, there's
a weird burble in the french horn. (The orchestral tracks were made by
internaly recording off high quality midi)

At first I thought, damn, the track got corrupted somehow. But soloing the
track it sounds find, while in the mix it sounds exactly like what happens
when there's an audio glitch. I A/B'd it in combination with other tracks
and lo and behold, when it's combined with the vocalist's track, which is
what the whole orchestration is being built around, in this one spot this
weird thing happens. Both tracks sound fine independently.

Any suggestions as to what possible cure there might be for this?

Does the vocalist track have any of the midi sound in it? Could they be
interfering?

How about large infrasonic (extreme LF) content?

No, it was recorded totally independently. There's actually no midi in the
track. The orchestration was originally done as midi, but then recorded into
wave files. I did it that way to use some effects such as Soundforge's
Acoustic Mirror to make the horns sound more distant and orchestral.

It appears to be some kind of eq issue. When these two spots encounter each
other, they seem to interfere with each other. I actually found one other,
less obvious spot where it also happens.

Uh....??

Does the vocalist say the letter "P" at (or just before) the time the glitch
happens?

Peace,

Could the vocalist have bumped the mic stand or done anything else to
create a pulse of very low frequency sound? It may be so low you can't
hear it but loud enough that it overloads your signal levels.

Run your vocals through a 100 Hz high pass filter and try the mix again.

They're saying the word "there's" with a big belting style "...you're here,
there's nothing I fear...." (Titanic theme) against french horns hitting
consecutive octaves.

Actually, I fixed it. After trying different EQ settings, I ended up drawing
in lowered volume on the one note in the french horns and it seems to have
put it below the threshold of whatever sonic dysfunction was occuring. It's
not an overload issue, there are much louder portions, but for some reason
this combination of sounds was a problem.

I have had a few weird things happen in multi track stuff. The last one was
a funny sounding note that was not there unless 3 tracks were played at the
same time. I only just guessed that it was some kind of phase/tuning with
these 3 notes out of tune just enough to cause a 3rd note to be synthesized
from the beat oscillations of these tunings. This was a 40 track project
and it like to have driven me crazy. This sound was not on any of the
tracks soloed but would only be there when these 3 tracks were played
together.

Which DAW was this? Logic by any chance (it happened to me too)

That's how some trombone players do 3 note harmony on a single trombone.
They play one note, hum another and the combination of the 2 harmonics
creates a 3rd "note". Saw Bill Watrous do it live in Monterey Ca. a few
moons back.

I once spent fifteen minutes trying to figure out why there was an obvious dog
bark in a song I was mixing, but hadn't recorded. Everyone heard it. It
turned out to be the combination of ac gtr fret buzz and a downstroke of a
fiddle bow- both innocuous by themselves, but ubelievably distracting together.

Another time I heard this horrific screech which seemed to come from behind the
mix position. That one turned out to be my wife yelling at me to "Turn it
down!"
