process: other peoples work to investigate
project: theremin
Assignment: Please do your own first patch and upload onto the wiki under your name
I did build a simple Theremin to get to know the workflow with Max. Move your mouse cursor around to control the pitch and volume.

project: screamie
If you scream loud enough ... you will get a selfie.
This little art is a first shot. Also: snarky comment on social media and selfie-culture.

Objects used:
- levelmeter~ - to display the audio signal level
- peakamp~ - find peak in signal amplitude (of the last second)
- past - send a bang when a number is larger then a given value
- jit.grab - to get image from camera
- jit.matrix - to buffer the image and write to disk
process: record and save audio and video data
This patch demonstrates how to get audio/video data and how to write it to disk.

Objects used:
- ezadc~ - to get audio input
- meter~ - to display (audio) signal levels
- metro - to get a steady pulse of bangs
- counter - to count bangs/toggles
- select - to detect certain values in number stream
- delay - to delay a bang (to get DSP processing a head start)
- jit.grab - to get images from camera
- jit.vcr - to write audio and video data to disk
process: retrieve images from a camera
This simple patch allows you to grab (still) images from the camera.
