Usage

Below are some usage examples. For more info, feel free to read DESCRIPTION.pdf and check out examples.py.

Please note that this project is in a prototype stage and is not optimized in terms of performance and reliability and is missing many planned features.

Overtones

from pynth import *

out = 0.5 * Sin(200)
for i in range(5):
  out += 0.1 * Sin(100*i)
  
drawgraph(out)
showsound(out, t2=0.1)
out.play(5*SR)

Vocal remover

sample, sr = librosa.load("file.wav", mono=False)
l = Wave(sample[0, :])
r = Wave(sample[1, :])
SR = sr

out = 0.5 * (0.5*l - 0.5*r)
out += 0.5 * MovingAvg(0.5*l + 0.5*r, M=50)

Procedural wind

noise = WhiteNoise()
cutmod = Unipol(.5*Sin(1/3) + .5*Sin(1/5)) * 0.1
resmod = Unipol((.5*Sin(1) + .5*Sin(.8)) >> 0.3)
resmod = resmod * 0.4 + 0.1
out = Scope(Lowpass(noise, cutmod, resmod))

Karplus-Strong string emulator

noise = Wave(np.random.rand(4000)-0.5)
delay = Delay(None, delay=0.005)
add = noise + delay
delay.ins["a"] = 0.95 * MovingAvg(add, M=10)
out = add

frozen = Wave(add.eval(2*SR))

User input, envelopes and scopes

import keyboard
control = Input()
env = Envelope(Scope(control), (2000, 0, 0, 8000))
out = Scope(env)
out = Scope(out * Saw(100))

val = 0
def loop(t):
  if keyboard.is_pressed(’l’):
    control.set(1)
  else:
    control.set(0)
    
out.play(30*SR, live=True, callback=loop)
