1087 encode_bformat B-Format Encoder. This plugin encodes ambisonic B-Format audio using the inverse square law but no filtering, reverb or delay.
1088 encode_fmh FMH-Format Encoder. This plugin encodes ambisonic FMH-Format audio using the inverse square law but no filtering, reverb or delay.
1089 fmh2bf FMH-Format to B-Format. This plugin simply discards the R, S, T, U and V channels but is included for clarity.
1090 bf2stereo B-Format to Stereo Ambisonic Decoder. This plugin only actually uses its W and Y input signals and does not use UHJ.
1091 bf2quad B-Format to Quad Ambisonic Decoder. This plugin only actually uses its W, Y and Z input signals.
1092 bf2cube B-Format to Cube Ambisonic Decoder.
1093 bf2oct FMH-Format to Octagon Ambisonic Decoder. This plugin only actually uses its W, X, Y, U and V inputs.
1094 bf_rotate_z B-Format Rotation (Horizontal). This plugin rotates an B-Format encoded soundfield around the Z-axis.
1095 fmh_rotate_z FMH-Format Rotation (Horizontal). This plugin rotates an FMH-Format encoded soundfield around the Z-axis.
1096 grain_scatter Granular Scattering Processor. This plugin generates an output audio stream by scattering short `grains' of sound from an input stream. It is possible to control the length and envelope of these grains, how far away from their source time grains may be scattered and the density (grains/sec) of the texture produced.
1097 wsshape_sine Wave Shaper (Sine-Based).
1098 identity_audio Identity (Audio).
1099 identity_control Identity (Control).
1123 freeverb3 Freeverb (Version 3). This reverb unit is a direct port of the free public domain source code available from Jezar at Dreampoint.
1221 analogue Analogue Synthesizer Voice. Contains two audio oscillators, one LFO, and three ADSRs. There are five waveforms available for the DCOs: Sine, Triangle, Square, Sawtooth, and Fullwave rectified sine. The DCOs may be frequency modulated and/or pulse width modulated by the LFO.
1222 organ Organ Voice with Configurable Harmonics. The user may control the loudness of the harmonics. There are three additional tones that may be enabled and combined: brass, flute, and reed. Two ADSRs control the envelope for the upper and lower harmonics.
1223 syndrum Drum Synthesizer.
1224 vcf303 VCF 303. A TB-303 resonant filter clone.
1225 canyon_delay Canyon Delay. A deep stereo crossdelay with built-in low pass filters.
1226 phasemod Phase Modulated Synthesizer Voice. Contains six audio oscillators, each oscillator phase modulates the next. If a modulation coefficient is zero, then the former oscillator's output is summed with the module's output. DCO1's phase modulation parameter specifies an offset not a coefficient. Example modulation parameters {1.0, 0.5, 0.0, 0.5, 0.2, 0.0} for all six oscillators results in the output function: DCO2 (phase = DCO1 (phase = 1.0) * 0.5) + DCO5 (phase = DCO4 (phase = DCO3 (phase = 0.0) * 0.5) * 0.2) + DCO6 (phase = 0.0). Each oscillator's output is bounded by -1.0 and 1.0, or -360o and 360o.
1227 lofi Lo Fi. Simulates old audio equipment. Adds distortion, bandwidth limiting, compression, and crackling to audio.
1841 pink_interpolated_audio Interpolated pink noise. Pink noise is a kind of random one-dimensional fractal. This plugin approximates the effect of an extreme low pass filter on a pink noise signal. It is useful as a natural-sounding continuously varying control signal with long-term trends as well as short-term variation. If you use it to control the pitch of a sine wave it can sound a bit like wind blowing. Notice that the average value tends to gradually drift over long periods of time. This is in the nature of pink noise, and so can't be helped.
1843 pink_sh Sample and hold pink noise. Similar to pink, but with stepped instead of interpolated output.
1844 pink_full_frequency Pink noise simulation with a full frequency range. You can low pass filter this to get a similar effect to the interpolated pink noise generator.
1845 hard_gate Hard noise gate. If the absolute value of the signal falls below "threshold", it is set to zero. There is no antialiasing.
1846 disintegrator Amplifies random half-cycles of it's input by multiplier. Set multiplier to 0 and vary probability for a weird fade effect, or set multiplier to -1 and probability to 0.5 to turn pitched sounds into noise.
1848 sledgehammer A Dynamic Sledgehammer, which you can use to bash your signals into shape. It's basically a very simple and heavy compressor with a sidechain. Try it with a pad sound as the carrier and a drum loop as the modulator. Also, you can get some nice "Satan Maximiser"-style distortion by not connecting the modulator (set it's influence to 0) and putting the rate up to around 0.1.
1849 logistic Logistic Map chaotic stepped control generator. The logistic map is a classic example from chaos theory. It can be summarised by the formula
x := r*x*(1-x).
With r<3, x just converges to a constant value. With r just greater than 3 it oscillates with period 2. at about 3.45 the period doubles again to 4. These period doublings occur at smaller and smaller increments of r, until at about 3.5699 there have been an infinite number and the signal never repeates. Between this value and 4 the system exhibits chaotic behaviour (although there are regions of periodicity). Papers are still being published today on the subject of this system's behaviour. This plugin iterates this map at a given frequency to produce a stepped signal, which is scaled to lie in the range (-1,1). When this signal is used as a frequency control it can sometimes sound quite musical.
