Nyquist-Shannon 0.1

instrument device

A demonstration of sampling rate and aliasing.

Basic function:

• draws a sine wave and shows the points that would be sampled at a certain sampling rate (doesn't actually change the sampling rate)
• phase shift to show that the sampled signal can differ, depending on it's timing
• aliasing artifacts: shows a possible different interpretation of the same sample points
• just a demonstration tool, not really meant to be a synthesizer

Used in: Tutorial 2

Oscilloscope 2.0

audio device

A lissajous oscilloscope

Basic function:

• uses one audio channel for horizontal deflection and the other one for vertical deflection
• different drawing modes and colors
• doesn't look very realistic, but works well for preview

sincos demo 0.2

instrument device

A patch to demonstrate the correlation between sine and cosine on a unit circle.

Starfield simulation screensaver for your oscilloscope

Basic function:

• sounds wonderfully awful and sometimes does unpredictable things

• after the time is up, the next star is drawn
• when stars move out of scope they reappear at a new random position
• some stars are spirals or smiley faces
