Struct Recipe 

pub struct Recipe { /* private fields */ }

The render recipe. Recipe::current is the only constructor, so a recipe always matches its version.

Implementations

impl Recipe

pub fn current() -> Recipe

Returns the recipe of RECIPE_VERSION.

• 44.1 kHz stereo, blocks of 512 samples, offline processing.
• Velocity 100. Bass plays MIDI 36, a lead or pluck MIDI 60 and a pad the triad 60, 64 and 67. Notes are MIDI numbers, because octave names differ per synth.
• The notes start at 0 s and are held 3 s. The clip is at least 4 s and grows until the tail is over (see TailWatch): the output stays below -96 dBFS for 1 s after the last note-off, or 30 s pass.
• The pre-roll after the state load, thrown away: 0.5 s of silence, a warm-up step of 1 s with MIDI 60 at velocity 100 held for its first 0.5 s, and 0.5 s of silence again.
• Vital renders at 2x oversampling, its default, whatever the preset stores.

pub fn version(&self) -> u32

Returns the version.

pub fn sample_rate(&self) -> SampleRate

Returns the sample rate.

pub fn channels(&self) -> u32

Returns the number of output channels.

pub fn block_size(&self) -> u32

Returns the block size in samples.

pub fn process_mode(&self) -> ProcessMode

Returns the process mode.

pub fn velocity(&self) -> Velocity

Returns the velocity of the recipe notes.

pub fn notes(&self, material: Material) -> Vec<RenderNote>

Returns the notes for material, each held from 0 s to the hold time.

pub fn clip(&self) -> Seconds

Returns the shortest clip.

pub fn pre_roll(&self) -> &[PreRoll]

Returns the pre-roll steps in the order they play.

pub fn settle(&self) -> Seconds

Returns the silence after the state load: the first settle step.

pub fn vital_oversampling(&self) -> Oversampling

Returns the oversampling of a Vital render.

pub fn tail_floor_gain(&self) -> f64

The tail floor as a gain: a sample below it in every channel is quiet.

pub fn tail_cap(&self) -> Seconds

Returns how long after the last note-off a tail may sound before the clip is cut.

pub fn tail_watch(&self, notes: &[RenderNote]) -> TailWatch

Starts a watch for the end of a clip that plays notes. The last note-off is the latest note-off frame of super::note_events, so a note shorter than a frame ends where its event does.
