Sine

Modulation to transform the square of the sound pressure to a sine wave.

Specify the frequency $f$ as an integer in the constructor.

use autd3::prelude::*;
#[allow(unused_variables)]
fn main() {
let m = Sine::new(150 * Hz);
}

#include<autd3.hpp>
int main() {
autd3::Sine m(150 * autd3::Hz);
return 0; }

using AUTD3Sharp.Modulation;
using static AUTD3Sharp.Units;
var m = new Sine(150u * Hz);

from pyautd3 import Hz, Sine
m = Sine(150 * Hz)

Set intensity and offset

Sine applies AM so that the waveform of the sound pressure is $$\frac{intensity}{2}\times \sin (2\pi ft)+offset$$ Here, $intensity$ and $offset$ can be specified by with_intensity and with_offset, respectively (defaults are 0xFF and 0x80).

use autd3::prelude::*;
#[allow(unused_variables)]
fn main() {
let m = Sine::new(150 * Hz)
            .with_intensity(0xFF)
            .with_offset(0xFF / 2);
}

#include<autd3.hpp>
int main() {
const auto m =
    autd3::Sine(150 * autd3::Hz).with_intensity(0xFF).with_offset(0xFF / 2);
return 0; }

using AUTD3Sharp;
using AUTD3Sharp.Modulation;
using static AUTD3Sharp.Units;
var m = new Sine(150u * Hz)
        .WithIntensity(0xFF)
        .WithOffset(0xFF / 2);

from pyautd3 import Hz, Sine
m = Sine(150 * Hz).with_intensity(0xFF).with_offset(0xFF // 2)
