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.

Noise

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

Envelopes

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

Processing

Dynamics

[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.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).

Math Operations

[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
