This is an AUv3 compatible stereo parametric equalizer which can be used as a plugin with your favourite DAW such as Cubasis, Meteor, Auria or GarageBand. It supports a graphical interface and presets with stereo metering to monitor signal levels. The equalizer allows you to define up to 4 frequency bands which can be cut/boosted up to 24dB. The Parametric EQ is a mainstay of recording and live sound production. In professional audio circles, equalization is a highly sophisticated art that can be used to sculpt the tone of instruments in a mix, counteract anomalies in a room, or just pump up the bass. This 4-band stereo EQ allows you to control of the gain (boost/cut) of low, midrange, and high frequency bands. Use the Q knob to adjust the ratio of the center frequency to the bandwidth. This type of EQ is great for guitars in order to emphesise certain harmonic frequencies or to remove unwanted narrowband noise. This is one of a suite of AUv3 compatible plugins which will also be available from 4Pockets.
