Compression Sends vs. Compression Inserts

Uncategorized

This post is going to focus on using compression on sends vs. compression on inserts in order to retain fidelity while adding punch.

Throwing up an insert on a track is an obvious way to control the dynamics of the track or to add punch. Unfortunately, sometimes adding compression to the sound itself dulls the high-end or introduces undesirable distortions, such as in the case of overhead cymbals or piano. One way to achieve the effect of punch or sustain without compromising the fidelity is send a copy of the signal to stereo send/aux with the desired compression effect on its insert and blend to taste.

Higher Gain Reduction with Better Fidelity

By doing this, you can achieve more dramatic pumping effects or higher gain reduction without touching the source signal. I believe I read that this is a favorite technique of Tom Lorde-Alge for adding splash to overheads.

Caveats

While blending in a send won’t control the dynamics of the source material – sometimes this is what you want. The natural tone and sustain of drums and other percussive instruments has a breathiness to it that compression can destroy. In this particular case, you may want to try having the compression send be the louder, primary track and blend the dry track in to taste. This way the dynamic transient of the drum won’t overpower the track as much. To do this, you would want to set the send to pre-fader so that the volume of the resulting compressed send won’t be affected by the volume of the original fader, allowing you to have a consistent ratio and threshold while changing blends.

Automation for Drum Sounds that Change

Often a solid compression level for a full-on snare hit is not the best setting for a cross stick or the like. So, when a drummer switches over, you either need to choose a compromised setting for both or bear having one setting sound less satisfactory. In these situations, automating the mutes on two separate compression sends can give you the best of both worlds.

    Hi .. a good topic.

    Can you please comment on a thing that why really these s/w like Nuendo/Sonar etc allow us to put the FX inserts per track especially reverb & compressors.

    Does that have a special reason ?

    Thanks & regards
    Happy New Year !

    Hey vtlabs…

    Seems to me that they leave the option to insert things on individual tracks simply to increase the flexibility. Sometimes you DO want to compress just a single track, or maybe you want to have a reverb on a single track element and then compress it, or have a send have an effect before it’s sent. Basically – why not? It’s better than having two dozen effects sends…

    Thx Dan :-)

    I was just anyways trying to rule out the “best possible” way … rather the best practice.

    One more thing … Well a reverb effect being directly proportional to the real room acoustics hence it seems better to share a single 100% reverb accross all channels thru the send bus … but now I feel that as Compression needs to be different per voice / instrument its better to put it oer track as an insert OR atleast can rarely be shared by multiple tracks if used thru send buses

    Thx
