Crate twang

A sound synthesis crate.

extern crate twang; // for sound generation / effects
extern crate adi; // for speaker
 
use twang as t;
 
fn main() {
    let mut speaker = adi::speaker::Speaker::new(0, false).unwrap();
    let mut gen = t::Generator::new(440.0, 1.0);
 
    loop {
        let x = gen.next();
 
        // Play synthesized voice.
        speaker.update(&mut || {
            // Do synthesis
            t::out(t::mul(&[
                t::dst(t::sin(x), 2),
                t::dst(t::saw(x), 2)
            ]))
        });
    }
}

Structs

Generator	An audio wave generator.
PnkGenerator	Pink Noise Generator.
WhtGenerator	White Noise Generator.

Functions

acs	Arcosine of a sound wave.
add	Add sound waves together. (Add sound waves ontop of eachother), may introduce clipping.
asn	Arcsine of a sound wave.
atn	Arctangent of a sound wave.
crt	Cube root of sound wave.
dst	Discrete step conversion of sound wave.
hrd	Distort sound wave with hard clipping. Volume should be more than 1 to have any effect.
inv	Invert sound wave (-x).
mix	Mix sound waves together. (Add soundwaves together, then divide by len)
mul	Multiply sound waves together, avoiding octave jump.
neg	Only the negative part of the wave.
out	Convert an f64 sample and volume to an i16 sample.
ovr	Generate sound from fundamental and overtones. For reverse FFT use twang::sin for the generator
pnk	Pink noise
pos	Only the positve part of the wave.
saw	A Saw wave
sft	Distort sound wave with soft clipping. Volume should be more than 1 to have any effect.
sgn	Signum of sound wave (-1 or 1)
sin	A Sine wave
sqr	A square wave
srt	Square root of sound wave.
tri	A triangle wave
wht	White noise
