Resonator¶

The resonator sound engine uses physical modeling techniques to create organic sounds. Two sound sources are available as exciters for two resonators.

Exciters¶

Two sound sources can be used simultaneously as input for the resonators:

The (white) noise source has a low-pass filter and ratcheting envelope:
- noise vol sets the volume of the noise oscillator.
- noise filt sets the low-pass filter cutoff frequency.
- ratchet sets the amount of ratcheting applied to the envelope.
The sample exciter can play sample lists and also has a low-pass filter:
- smp vol sets the volume of the sample player.
- smp filt sets the low-pass filter cutoff frequency.
- samples sets the sample list from which a sample is picked for each new note.

Resonators¶

The exciters are fed into the two resonators: the positive resonator which sounds more like a sawtooth wave, and a negative resonator which will sounds more like a square wave.

pos decay and neg decay set how long the resonators will resonate, with 0% being no resonance and 100% being near infinite resonance.
dampening sets how quick higher frequencies are attenuated in the resonators. A low value means there is very little attenuation while high values will make the higher frequencies will disappear faster.
pos/neg mix sets the output mix between both resonators with 0% being only the positive resonator and 100% being only the negative resonator.
bit depth sets the bit depth of the resonators. Lower values will apply more digital erosion of the resonating signal and result in a shorter overall decay time, while a value of 32 results in no digital erosion.

Warning

Due to the resonating nature of this sound engine it is recommended to add a limiter or compressor in the audio effects chain to limit unexpected peaks, which are likely to occur when using long and/or pitched samples.
