Audio Effects

Wether you’re using a synth or a sample, you can apply any of the following built-in audio effects. As you might suspect, the effects can be chained together, and they accept a pattern string as their argument.

bandf

Sets the center frequency of the band-pass filter.

  • frequency (number|Pattern): center frequency
s("bd sd,hh*3").bandf("<1000 2000 4000 8000>")

bandq

Sets the q-factor of the band-pass filter

  • q (number|Pattern): q factor
s("bd sd").bandf(500).bandq("<0 1 2 3>")

coarse

fake-resampling for lowering the sample rate. Caution: This effect seems to only work in chromium based browsers

  • factor (number|Pattern): 1 for original 2 for half, 3 for a third and so on.
s("bd sd,hh*4").coarse("<1 4 8 16 32>")

crush

bit crusher effect.

  • depth (number|Pattern): between 1 (for drastic reduction in bit-depth) to 16 (for barely no reduction).
s("<bd sd>,hh*3").fast(2).crush("<16 8 7 6 5 4 3 2>")

cutoff

Applies the cutoff frequency of the low-pass filter.

  • frequency (number|Pattern): audible between 0 and 20000
s("bd sd,hh*3").cutoff("<4000 2000 1000 500 200 100>")

gain

Controls the gain by an exponential amount.

  • amount (number|Pattern): gain.
s("hh*8").gain(".4!2 1 .4!2 1 .4 1")

hcutoff

Applies the cutoff frequency of the high-pass filter.

  • frequency (number|Pattern): audible between 0 and 20000
s("bd sd,hh*4").hcutoff("<4000 2000 1000 500 200 100>")

hresonance

Applies the resonance of the high-pass filter.

  • q (number|Pattern): resonance factor between 0 and 50
s("bd sd,hh*4").hcutoff(2000).hresonance("<0 10 20 30>")

pan

Sets position in stereo.

  • pan (number|Pattern): between 0 and 1, from left to right (assuming stereo), once round a circle (assuming multichannel)
s("[bd hh]*2").pan("<.5 1 .5 0>")

resonance

Applies the cutoff frequency of the low-pass filter.

  • q (number|Pattern): resonance factor between 0 and 50
s("bd sd,hh*4").cutoff(2000).resonance("<0 10 20 30>")

shape

Wave shaping distortion. CAUTION: it might get loud

  • distortion (number|Pattern): between 0 and 1
s("bd sd,hh*4").shape("<0 .2 .4 .6 .8>")

velocity

Sets the velocity from 0 to 1. Is multiplied together with gain.

    s("hh*8")
.gain(".4!2 1 .4!2 1 .4 1")
.velocity(".4 1")

    vowel

    Formant filter to make things sound like vowels.

    • vowel (string|Pattern): You can use a e i o u.
    note("c2 <eb2 <g2 g1>>").s('sawtooth')
.vowel("<a e i <o u>>")
