Another demo of my Audio to Midi application made with Processing.

The audio reaction is realtime analysis of the microphone input on my laptop. Each frequency band meter (let column) is auto-levelling and produces normalised output (a floating point value between 0 and 1, inclusive). The "monitors" (right column) can be each be attached to any of the meters. The monitor output values are between 0 and 127, and if a MIDI output device is selected, the value is emitted as a control message if different to the previous value (which is most of the time for a non-silence audio signal!). The range of monitor output values can be reduced; the "low" and "high" values can be set independently for each monitor, where the "low" value can actually be higher than the "high" value (for an inverse reaction to the related frequency meter).

The changing output levels and connections to various frequency bands in the video is due to me using keyboard controls for the application (they are not automated... yet). Controls include random range allocation (for single monitor or all monitors), flip (swap low and high value) range(s), invert range(s), reset range(s), random meter connection(s), pause and mute.

Recorded during an EveryOne gig at 202 Broadway.
