Enum Transform 

pub enum Transform<'a> {
    Waveform(WaveformFn<'a>),
    Points(PointsFn<'a>),
}

Transformation of the recorded audio, displayed in the lower half of the LiveVisualizer window.

Called with the latest audio samples (mono amplitudes in [-1.0, 1.0]) and the sample rate in Hz, once per rendered frame. The closures may hold state (FnMut), e.g. for smoothing across frames.

Variants

Waveform(WaveformFn<'a>)

The output is a waveform on the same time axis as the input, e.g. a filtered version of it.

Points(PointsFn<'a>)

The output is a series of arbitrary (x, y) points, e.g. a frequency spectrum.

Implementations

impl<'a> Transform<'a>

pub fn waveform(f: impl FnMut(&[f32], f32) -> Vec<f32> + 'a) -> Self

Creates a Transform::Waveform.

pub fn points(f: impl FnMut(&[f32], f32) -> Vec<(f64, f64)> + 'a) -> Self

Creates a Transform::Points.
