recording a clip with EQ already on it... [pre-file]

No. Can I ask what you're trying to do? There may be a workaround.

If you have an interface that can do a digital loopback of an output to an input, you can re-record the effected signal on a second track in real time with only buffer latency added. An analog loopback will also work, but you'll have another round of D/A/D conversion.

OK. Thanks for the ideas. So ya, i guess i should explain what i'm doing... I'm doing a little sleep study on the side, involving sleep apnea, and i need to record the breathing patterns of a subject which can sometimes get very quiet, so i have to set my preamp gain to maximum. The result of needing to record such low levels is that the slightest street noise and feet on floor noise from the apartment above overwhelms the breathing noise - mostly low frequency noise. OK, so so far i have simply filtered out the unwanted frequencies during playback, and that has work reasonably well, but the files are eight or nine hours long, so i am looking for a way to visually look for the sleep 'apnea' patterns in the recording instead of listening to the whole clip. ..... .... I can try bouncing the track with filters and compression on the track, but since it's a nine hour track, i thought i'd look for possible alternatives first. It is a huge file too even at 16 bits mono. It doesn't look like i can set it to 8 bits either... I guess i'll try bouncing it though, and let you know how long it takes. I can always abort the process if i need to, right?
