Struct VoicesLayer 

pub struct VoicesLayer {
    pub mono: bool,
    pub max_polyphony: usize,
    pub mean_polyphony: f64,
    pub joins: Vec<Join>,
    pub confidence: Confidence<NoSpread>,
}

The voices layer of a stem.

Fields

mono: bool

One voice at a time, by VoicesLayer::max_polyphony.

max_polyphony: usize

The most voices at once.

mean_polyphony: f64

The mean count over the time that any note is held. An overlap under OVERLAP_MIN counts here and not in max_polyphony, so this can exceed it.

joins: Vec<Join>

The joins of a mono line, in time order; empty on any other line.

confidence: Confidence<NoSpread>

The confidence of the count; no estimate without notes or when no note holds a sounding part in the stem.

Implementations

impl VoicesLayer

pub fn of(input: &VoicesInput<'_>) -> Result<Self, VoicesError>

Errors

Returns a VoicesError when a confidence or a spectrum cannot be built.

pub fn summary(&self) -> Vec<String>

The lines the command prints.
