heavylib

Library of heavy compatible abstractions.

See the -help.pd patches for more information on each object.

Synthesis

Band-limited oscillators

[hv.osc~ saw] - Band-limited PolyBlep sawtooth signal generator. more info

[hv.osc~ sine] - Same as Pd [osc~] added for convenience.

[hv.osc~ square] - Band-limited PolyBlep square signal generator.

LFOs

These precision LFOs have control rate inlets and outlet, however they sample from signal rate oscillators and require DSP to be on.

They give a float output between 0.0 - 1.0. Because we [snapshot] every 1ms we get aliasing when we enter audio range frequencies.

[hv.lfo sine] - Control [snapshot~] of slow [osc~].

[hv.lfo ramp] - Control [snapshot~] [phasor~].

[hv.lfo saw] - Control rate sample and inverted [phasor~].

[hv.lfo square] - Amplified and clipped [osc~], has phase offset.

[hv.lfo pulse] - Band-limited PolyBlep square signal generator, taken from [hv.osc~ square], instead of phase offset we get pulse width modulation.

Noise

[hv.pinknoise~] - Cheapish pinknoise generator. more info

Envelopes

[hv.vline~] - Envelope generator, replacement for Pd's [vline~] object.

Processing

Dynamics

[hv.compressor~] - Compressor unit with Threshold and Ratio parameters. (Attack/Release is fixed at 40ms)

[hv.compressor2~] - Stereo version of [hv.compressor~].

[hv.envfollow~] - Cheap envelope follower.

Effects

[hv.comb~] - Comb filter effect unit.

[hv.flanger~] - Flange effect unit.

[hv.flanger2~] - Stereo version of [hv.flanger~].

[hv.freqshift~] - Frequency shifter effect unit.

[hv.reverb~] - Simple reverb unit.

Filtering

[hv.filter~ allpass] - Allpass filter with Q control (Biquad).

[hv.filter~ lowpass] - Lowpass filter with Q control (Biquad).

[hv.filter~ highpass] - Highpass filter with Q control (Biquad).

[hv.filter~ bandpass1] - Bandpass filter with Q control, peak gain = Q (Biquad).

[hv.filter~ bandpass2] - Bandpass filter with Q control, constant 0dB peak gain (Biquad).

[hv.filter~ notch] - Notch filter with Q control (Biquad)

[hv.filter.gain~ peak] - Peaking filter with Frequency, Q and Gain parameters (Biquad).

[hv.filter.gain~ lowshelf] - Low shelving filter with Frequency, Q and Gain parameters (Biquad).

[hv.filter.gain~ highshelf] - High shelving filter with Frequency, Q and Gain parameters (Biquad).

[hv.lop~] - Lowpass variant with signal controlled cutoff (rpole~).

[hv.hip~] - Highpass variant with signal controlled cutoff (rpole~).

Math Operations

[hv.exp~] - Signal-rate exponential ( exp ), alternative implementation.

[hv.eq~] - Signal-rate equal ( == ).

[hv.neq~] - Signal-rate not equal ( != ).

[hv.gt~] - Signal-rate greater than ( > ).

[hv.gte~] - Signal-rate greater than or equal to ( >= ).

[hv.log~] - Signal-rate natural logarithm ( ln ).

[hv.lt~] - Signal-rate less than ( < ).

[hv.lte~] - Signal-rate less than or equal to ( <= ).

[hv.multiplex~] - Mix between two input signals based on a comparator.

[hv.pow~] - Signal-rate exponent ( x ^ y ), alternative implementation.

[hv.tanh~] - Static non-linear waveshaper.

Logic

[hv.dispatch] - Utility for organising parameter interfaces to other abstractions.

[hv.drunk] - Randomised walk number generator.
