what is jackEQ?

jackEQ wll allow sound as rich and powerful as Jackie O, as street smart as Jackie Brown. Is jackEQ more than you can handle?

jackEQ is intended to provide an accessible method for tweaking the treble, mid and bass of any JACK aware applications output. Designed specifically for live performance, it is modelled on various DJ mixing consoles which the main author Patrick Shirkey (aka DJ Kotau) has worked with live.

jackEQ is a tool for routing and manipulating audio from/to multiple input/output sources. It runs on the JACK audio system, and uses the DJ EQ swh ladspa plugin created by Steve Harris, also one of jackEQ's major contributors along with Jack O'Quin who crafted the majority of the JACK ports menu code.

Audio Signal Management

 
Each channel has stereo i/o which can be connected in four ways:
 
- Directly
- To aux send 1 or 2
- To the master channel with xfade
- To the monitor out pre gain
 
Aux send slider/meter controls the input volume. Input is sent direct to master and can also be sent to monitor pre gain.
 
In total there are 16 input and 16 output connections.
 
If necessary you can also connect directly to the monitor and master inputs from any other JACK app.
