Title: Soundforge: using delay when mixing 2 sources
Post by: cbd on June 04, 2007, 11:55:21 AM
hey folks. I made a 4 channel recording (2 aud, 2 sbd) with my 744 on Fri and was looking for the direct or easiest way to insert some post recording delay on the sbd source. I have mixed it without the delay and it sounds ok but I'd like to use the delay to compare how the kick drums sound before I seed it. In the past I have used the delay built in the 744 and can't remember how to use it with SF.

thanks

If I understand you correctly I recommend simply nudging one source or the other in time until thy are alighned to your liking. You could get the same effect by using a buffer plug in to delay the playback of a track. I don't think an actual delay plug in would be the way to go. Oh, and use your ears more than your eyes. Good luck.

exactly. The 2 places I think you frequently hear the dleay issue is in the vocals & the drums. Based on my ears, the vocals sound fine to me but I hear some slight slight echo with the drums.

I am pretty low-fi in my knowledge of plug ins so that may be above my paygrade but I think I understand you are saying soundforge doesn't have true "delay" and that instead, just allign the 2 sources however many liliseconds ahead from the start on the audience source....

Yeah. I haven't used soundforge in many years (went Mac a while ago) but I recommend sliding the track to align the time. If I record a four channel recording (2 stereo) I usually do this, then trim to make them the same length before I back up the origional recording. That way they don't need to be aligned again in the future.

not an answer but a question of my own.  how far from the stage/pa were you?  we are gonna do this for the patterson party.  my ceiling rig is about 15' from stage so i think I should be fine.

Technically there is a delay at any location. Even onstage you'll have different amounts of delay from different instruments. I find that worrying about the low end is most important as it seems to be effected most by phase issues.

I've done many matrix's at this bar with just my v3 > jb3 and sbd > jb3 so two different world clocks (right since one is v3 > jb3).  never had any issues doing them in montage/wavelab.   this will all be analog (v3 > 744, & sbd > 744) so I should be good to go.

gordon:
the "conventional wisdom" is that you need delay when the mics are around 35 ft from the PA. There may still be some delay at closer distances but anything less is largely inaudible.
