POP Sound Shaper

POP Sound Shaper free compressor by Cut Through Recordings

POP Sound Shaper is a free compressor VST, VST3, Audio Unit, LV2 plugin developed by Cut Through Recordings. Compatible OS(s): Windows 64b, macOS.

Introducing POP, the all new dynamics Plug-in from Cut Through Recordings. POP is designed with one goal in mind: give your tracks the pop that they have been missing. POP Sound Shaper is a compressor/clipper combo. It is also great for getting more control over the dynamic range of your track without losing its transients. The compressor is designed to bring out the transients of the signal. It does this by having attack and release times set to let the transients pass and then immediately clamp down on the signal. These times are locked in to make using POP as simple as possible. Set the Amount of compression and set the threshold and you’re done. The compressor is followed by a soft clipper just incase you want to trim some of the higher peaks. POP also features two tone controls “Thump” and “Air” which are also dialed in to help make your tracks pop.

Features:

  • Input/output gain adjustment.
  • Unique display to visualize dynamics in real-time.
  • Compressor fine-tuned to bring out the “pop” in your tracks.
  • Controls to increase “Thump” and “Air”.
  • Mix control to allow parallel compression.

POP Sound Shaper is available in VST format for Windows (32-bit and 64-bit), VST & AU for Mac OS X (32-bit and 64-bit), and VST for Linux (64-bit).

It offers a dedicated input stage featuring crunchy pre-amp saturation and a brickwall safety limiter in the output stage. Everything is set up to work in zero latency and so be available for hassle free tracking and mixing.

Two dedicated filters can be used in either the audio path or in the compressor’s sidechain which can be external as well. Whether pre or post compression, the equalizer section offers four interacting coloring tools with well-selected musical sounding curves. The concept gets rounded off by a phase alignment tool which can be used for coloring purposes as well.
