compression in sends ?

dj_who · 26th March 2006

reading another thread titled "distortion on sends" made me want to ask this question:

is it a bad idea to have a compressor plugin on one of my sends ? so if i have 3 vocal tracks, by having a comp on the sends, all would share that one compressor.

i'd like to do this so save on cpu recources.

the only problem i see is that i have my sends after the inserts which have the eq. hmmmm

thanks for any advice

i'm going to try this now and experiment

IMHO you are heading for a phase NIGHTMARE due to varied plug in latency between the original signal and all the diffferent plug ins.

But try it and let us know how you get on!

i have cubase sx3 which has delay compensation. so i was thinking it shouldn't be a problem... but i'll see.

thanks

The 'action' of the compression - will be different in different compressors - outputting very slightly different phase on the 'manipulated / altered' part of the processed sound .....it's this that I predict will mess you up when combined.

It is the phenomenon I describe above , and my own tests with Pro Tools, that have led me to believe that mix techniques such as the Michael Brauer multi bus compression, hardware mixing method - will not work ITB (with plug ins within a digital mixer) But I honestly look forward to be proved wrong.

Brauer A, B, C an D busses are not parallel busses (not parallel to the source) except peridoaly as an "out".

Doesn't HD have an auto compensation?

The other thing you can do for parallel effects, it's a long work around, is duplicate the tracks, and effect one set and hten slide them ahead to compensate for the latency.

Except for when one source is going to multiple effected busses...what would that be, perpendicular compression™?

Would freezing the effects as a new track work well for this?? That way all tracks are individually comp'ed and save CPU

Jules,

Paralell compression with plug-ins, or hardware is NO problem with the built-in latency comp in Pro-Tools HD. Works like a charm.

Actually i think you are spot on there Jules.

A lot of the better comp plugins have a wet/dry mix so you can do parallel compression within the plugin, with no phase worries.

In my experiences, some comp plugins give zero phase shift after processing, and others do. You can check this by making a cloned track, processing, inverting the phase and checking if it cancels completely. This is a cool way to hear just what a compressor is actually doing. But some of the better sounding plugins actually introduce phase smearing which rules that out.
