Stereo and Mono Sidechain Compressors for Tracktion
Using the EQ to drop off the lows
There is another useful and common application for a Sidechain Compressor:
If you have a Guitar track, and you do not want the low frequencies compressed, you can place an
EQ in the Key Input to roll off the lows. The EQ passes only the mids and highs into the Key Input,
and therefore the compressor will only apply compression for these frequencies. It will not compress
during the dynamic low-frequency manglings your guitarist is known for.
1. Follow steps 1 to 4 on pages 12 and 13 to add the Sidechain Compressor to your guitar track.
2. Click on the EQ to bring up the EQ graph, and adjust it to roll off the lows. Use the Key Solo but-
ton on the compressor to audition its effect.
3. Remember that the rolling-off is only happening to the Key Input, and not your main guitar track.
It just means the compression will not be triggered by any low-frequency peaks.
4. You can use this technique to make the compression occur (or not occur) for any frequency band
you wish.
