Spectral valley carving

CTTRClear the haze between the peaks.

CTTR deepens the quiet dips between a sound’s own peaks. Use it on a single track to reduce low-level haze while leaving the louder peaks in place.

CTTR plugin interface
Actual plugin interface. The control preview below does not process your audio.

What CTTR does

Depth

Set how much of the quiet material CTTR removes.

Focus and response

Shape the carve and choose how quickly it reacts to the input.

Delta monitoring

Hear what the plugin removes while you adjust the processing.

Bass and air

Adjust the treatment at the low and high ends.

Try it in a session

  1. Insert CTTR on the track you want to carve. It works on that track’s own spectrum and does not need a sidechain.
  2. Raise Depth gradually and compare against bypass at a similar listening level.
  3. Use Delta to check the removed material. Back off if you lose body or detail you want to keep.

CTTR carves spectral valleys. It is a different process from a resonance suppressor that reduces peaks; choose it for the material you want to remove.
