Bitmap Caching
Caches bitmap images so that they are processed out of RAM. Located in the contextual properties of the graphics you click on.
In actionscript you can use the moveclip.cachebitmap boolean property.
Filters
Predefined filters are available in the timeline as well as in raw actionscript. These are very similar to filter additions in bitmap video imaging programs.

Additive Synthesis: Adding sine waves to create new sounds.
Subtractive Synthesis: Extracting waveforms from existing sounds.

VCO: Voltage Controlled Oscillator
Different Waves:
Sine, Square, Triangle, Sawtooth, and noise (arguable)
Fundamental is the raw tone that someone hears, which is open to each user’s interaction to that sound. Off of the fundamental, other frequencies and noise are layered on top of this to create the overall “sample” or synthesized sound.
Pulse Width Modulation doesn’t change the tone structure of a wave, but changes qualities of the overtones of a square wave.
Other waveform synthesis:
FM Synth
Granular Synth
Microsound Synth
Brownian Synth
Sample Synth
“Q” is way of amplifying the cutoff frequency.
“Filter Sweeping” is a general change of filtering over time causing dominant pitches and fundamentals to appear.
