Struct AnalyticField 

pub struct AnalyticField {
    pub amplitude: Vec<f32>,
    pub phase: Vec<f32>,
    pub frequency: Vec<f32>,
    pub latency: usize,
}

The analytic reading of a scalar signal: its envelope and its current position inside that envelope.

FlowField answers which way a signal is heading. This answers how widely it is swinging and how fast it is swinging, which a slope cannot separate: a signal oscillating with a growing envelope has a slope that keeps changing sign while the envelope only rises.

Fields

amplitude: Vec<f32>

Instantaneous amplitude, the local envelope of the signal.

phase: Vec<f32>

Instantaneous phase in (-pi, pi], position within the oscillation.

frequency: Vec<f32>

Instantaneous frequency in radians per token, the phase advance.

Unlike the resonator bank’s, this is not prescribed: the bank rotates at the frequency it was tuned to whatever the input, while this is read off the signal and changes with it.

latency: usize

Tokens of group delay. Index i reads the signal around i, using input up to i + latency, so the reading is causal with latency rather than centered on unseen input.

Implementations

impl AnalyticField

pub fn amplitude_at(&self, i: usize) -> f32

Envelope at a token index, or 0.0 past the end.

pub fn frequency_at(&self, i: usize) -> f32

Instantaneous frequency at a token index, or 0.0 past the end.
