Struct RubatoProfile 

pub struct RubatoProfile { /* private fields */ }

Describes how much tempo can stretch for an agent.

A RubatoProfile sets the boundaries of permissible timing flexibility. An agent with high stretch can borrow a lot of time; one with low stretch must stay close to the written tempo.

Implementations

impl RubatoProfile

pub fn new( name: impl Into<String>, max_compress: f64, max_stretch: f64, transition_rate: f64, ) -> Self

Create a new rubato profile.

pub fn strict() -> Self

Strict profile: minimal tempo flexibility.

pub fn moderate() -> Self

Moderate profile: balanced flexibility.

pub fn expressive() -> Self

Expressive profile: wide tempo flexibility.

pub fn apply(&self, base_bpm: f64, factor: f64) -> f64

Apply rubato to a base BPM, given a stretch factor.

factor ranges from -1.0 (max stretch/slow) to +1.0 (max compress/fast).

pub fn min_bpm(&self, base_bpm: f64) -> f64

Compute the minimum BPM allowed by this profile.

pub fn max_bpm(&self, base_bpm: f64) -> f64

Compute the maximum BPM allowed by this profile.

pub fn is_within_range(&self, base_bpm: f64, actual_bpm: f64) -> bool

Whether a given BPM is within the rubato range for a base BPM.

pub fn name(&self) -> &str

pub fn max_compress(&self) -> f64

pub fn max_stretch(&self) -> f64

pub fn transition_rate(&self) -> f64

Trait Implementations

impl Clone for RubatoProfile

fn clone(&self) -> RubatoProfile

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RubatoProfile

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for RubatoProfile

fn eq(&self, other: &RubatoProfile) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
