This package contains small abstractions to assist you in creating realtime audiovisual works. The objects are designed to work together with the already wide range of jitter objecst in Max. All the objects are created with vanilla Max, and therefore can be opened and inspected from the inside, and also have zero dependencies on other externals or packages.

Objects range from signal analysis that can be used to control visual parameters, objects that allow controlling events in time with transport, objects that extend/wrap some jitter objects, some object mappings to initialize jitter objects with common used attributes and more. Almost all of the objects have help-files with small examples and suggestions on how to use the objects.

• av.amp~ - A simple envelope follower for audioreactive visuals.

• av.follow~ - A more sophisticated envelope follower with low and highpass cutoff and a fast and slow follower to detect transients better and filter out low frequency information.

• av.follow3~ - Split a signal into low, mid and high frequency bands and apply an envelope follower.

• av.ampgate~ - An envelope follower (using av.follow~) that ouputs a gating signal when the amplitude crosses the threshold. It has a hold time and attack release for the gate.

• av.trigger~ - An envelope follower (using av.follow~) that outputs a bang and gate signal based on a set upper and lower threshold.

• av.catch~ - Catch amplitudes of 3 different signals in time and output as 3-plane matrix. Generates a 3-dimensional oscilloscope (X Y Z).

• av.spectrum~ - Grab an FFT frame (spectrum) from an incoming signal and output as a one-dimensional jitter matrix.

• av.spectrogram~ - Grab a history of successive FFT frames (spectrum) from an incoming signal and output as a 2-dimensional jitter matrix.

• av.midside~ - Split a stereo signal into mid (R+L) and side (R-L, L-R) information.

• av.cross3~ - Split a signal into low, mid and high frequency bands, with adjustable cross-over frequencies.

• av.when - Combine with (named) [transport]. Displays the current time in min:sec:ms.

• av.timepoint - Combine with (named) [transport]. Outputs a bang at a specified timepoint in min:sec:ms.

This package includes mappings for the jit.gl.slab, jit.gl.shader, jit.gl.pix and jit.gl.pass objects (formerly based on the project gl.shadermappings).

Max has quite a few shaders shipped with the application, but if you want to patch with them you have to type jit.gl.slab @file <shaderfile>, or jit.gl.pass @fxname <name>. It can be hard to remember what the name of the file is that you're looking for. Also you might not know all the possibilities out there, so it would be nice to have a list of options in the autocomplete field. These simple objectmappings will do all this work for you and allow you to browse the various files through from the autocomplete list. How it works:

1. See all the files in the autocomplete list when typing jit.gl.slab., jit.gl.shader., jit.gl.pix. or jit.gl.pass.
2. Select the effect, press enter and the object will automatically be substituted for jit.gl.slab @file <your-selected-file>
