Module bands 

Structs

BandFloor

A filter cannot report an onset faster than its own, so a caller subtracts this.

BandTrack

Bands

Prune

eps_db over LEAST_PRUNE_DB; floor_db under 0, against each band’s own peak.

PrunedBand

PrunedBands

rate_hz is the source rate a knot’s index counts at.

Smoothing

hz: None is the band’s own ERB, capped at a quarter of the decimated rate.

Constants

BAND_COUNT

DECIMATED_HZ

Under the 2-3 ms gap-detection limit, a hundredth of the samples it came from.

FIRST_CAM

1 to 40 Cam is 26 Hz to 16.7 kHz.

HIGHEST_CENTRE_OF_RATE

LEAST_PRUNE_DB

Under this a bound is finer than the tens of dB a level spans hold in an f64, so no evaluated error could certify it: a correctness limit, not a cost one.

PRUNED_MODEL

Functions

analyze

cam

One Cam is one filter width along the cochlea.

erb_hz

Glasberg and Moore’s auditory filter width in Hz.

hz_at_cam

least_rate_hz

pruned

smoothed

Type Aliases

Knot

A source sample’s index from the read’s start, and the level there in dB.
