This is a AUv3 compatible audio compressor which can be used as plugin with your favourite DAW such as Cubasis, Meteor, Auria or GarageBand. It supports a modern graphical interface and presets with stereo meters for monitoring signal levels.

An audio compressor is used to reduce the volume levels of loud sounds above a specified threshold and amplify quiet parts thus reducing an audio signals dynamic range. The dynamic volume changes of a recording means that the overall level of the compressed recording can be increased inside your mix. The recording will also sit inside your whole mix much more easily.

The latest version has a new experimental sidechain option which allows you to host two instances of the same plugin and use one to push audio through one of 3 busses which others can use those busses as input for the compressor. This allows you to get that 'Trance' like pumping action going on. This has been tested in AUM, Cubasis and GarageBand although it may not work in all DAW's. It is possible for instance to place a compressor on a bass drum and push audio to Bus 1, then have several other tracks taking input from Bus 1 allowing the volume of the bass drum to attenuate their respective tracks. Default compressor functionality is disabled when used as a sidechain source in this way.

This is one of a suite of AUv3 compatible plugins which will also soon be available from 4Pockets.
