Function synfx_dsp::process_1pole_highpass

pub fn process_1pole_highpass(
    input: f32,
    freq: f32,
    israte: f32,
    z: &mut f32,
    y: &mut f32
) -> f32

Process a very simple one pole 6dB high pass filter. Useful in various applications.

• input - Input sample
• freq - Frequency between 1.0 and 22000.0Hz
• israte - 1.0 / samplerate
• z - The first internal buffer of the filter.
• y - The second internal buffer of the filter.

    let mut freq = 1000.0;

            process_1pole_highpass(*s, freq, 1.0 / 44100.0, &mut z, &mut y);
        // ... do something with the result here.
