(see unit generators under the language specification)

standard ugens
audio output
[ugen] dac	digital/analog converter abstraction for underlying audio output device
[ugen] adc	analog/digital converter abstraction for underlying audio input device
[ugen] blackhole	sample rate sample sucker ( like dac, ticks ugens, but no more ) see examples: fm.ck
[ugen] Gain	gain control (NOTE - all unit generators can themselves change their gain) (this is a way to add N outputs together and scale them) see examples: i-robot.ck
wave forms
[ugen] Noise	white noise generator see examples: wind.ck powerup.ck
[ugen] Impulse	pulse generator - can set the value of the current sample default for each sample is 0 if not set
[ugen] Step	step generator - like Impulse, but once a value is set, it is held for all following samples, until value is set again see examples: step.ck
oscillators
[ugen] Phasor	phasor - simple ramp generator ( 0 to 1 ) this can be fed into other oscillators ( with sync mode of 1 ) as a phase control.
[ugen] SinOsc	sine oscillator
[ugen] PulseOsc	pulse oscillators a pulse wave oscillator with variable width.
[ugen] SqrOsc	square wave oscillator ( pulse with fixed width of 0.5 )
[ugen] TriOsc	triangle wave oscillator
[ugen] SawOsc	sawtooth wave oscillator ( triangle, width forced to 0.0 or 1.0 )
[ugen] Gen5	exponential line segment lookup table table generator
[ugen] Gen7	line segment lookup table table generator
[ugen] Gen9	sinusoidal lookup table with harmonic ratio, amplitude, and phase control
[ugen] Gen10	sinusoidal lookup table with partial amplitude control
[ugen] Gen17	chebyshev polynomial lookup table
[ugen] CurveTable	flexible curve/line segment table generator
[ugen] WarpTable	end-constrained mapping table useful for control signal conditioning

[ugen] BPF	band pass filter. 2nd order butterworth. (may be expanded to include higher orders and other types later)
[ugen] BRF	band reject filter. 2nd order butterworth. (may be expanded to include higher orders and other types later)
[ugen] ResonZ	resonance filter. BiQuad with equal-gain zeros
[ugen] Dynamics	dynamics processor includes limiter, compressor, expander, noise gate, and ducker (presets) see examples:
basic signal processing
[ugen] HalfRect	half wave rectifier for half-wave rectification.
[ugen] FullRect	full wave rectifier
[ugen] ZeroX	zero crossing detector emits a single pulse at the the zero crossing in the direction of the zero crossing. (see examples: zerox.ck)
file i/o
[ugen] SndBuf	sound buffer ( now interpolating ) reads from a variety of file formats see examples: sndbuf.ck
stereo < -- > mono
[ugen] Mix2	mix from stereo signal to mono
