Struct Features 

pub struct Features {
    pub audio: AudioFeatures,
    pub structural: StructFeatures,
    pub vet: VetReport,
    pub lufs_before: f64,
    pub gain_db: f64,
    pub peak_reduction_db: f64,
}

Everything the taste model and audition path need for one candidate.

Fields

audio: AudioFeatures

Perceptual descriptors of the normalized render.

structural: StructFeatures

Render-free structural descriptors of the term.

vet: VetReport

Raw-render measurements from the vet gate.

lufs_before: f64

Integrated loudness before normalization (LUFS).

gain_db: f64

Gain applied (dB) — toward TARGET_LUFS, but never past auracle_features::PEAK_CEILING.

peak_reduction_db: f64

Makeup gain given up so the render would not clip, in dB (≥ 0).

Zero for most patches. Positive means this one auditions below TARGET_LUFS because its crest factor would not let it reach the target without going over full scale — so a surface comparing two candidates’ levels can say which of them was pulled down and by how much, rather than presenting a peak-limited patch as a quiet one.

#[serde(default)] is forward-looking rather than a migration. Features cross the farm as crate::CachedFeatures within a single boot, where the worker’s version stamp guarantees one build on both ends, and nothing persists them across boots today — BankEntry stores trees, so a reloaded pool is re-featurized under whatever normalizer is current. The default matters the moment the persistent render cache lands, and the thing to note there is that a row written before this ceiling carries a gain_db that would clip: normalization changing has to invalidate the cache namespace, not merely default a field.

Implementations

impl Features

pub fn phi(&self) -> Vec<f64>
