Detailed Description

The air a strike moves: a longer, coloured noise layer under the body.

Distinct from the click in what it is for, not just in how long it lasts. The click is the contact; this is the sound of the head and the room responding to it, which is why it is coloured (the spectrum is tilted) and decays over tens or hundreds of milliseconds rather than a few.

RT contract: prepare() allocates nothing; every other method allocates nothing and takes no locks.

Member Function Documentation

is_active()

bool pulp::signal::drum::NoiseLayer::is_active ( ) const

inline

A silent layer is never active – see the note on ClickLayer.

level()

double pulp::signal::drum::NoiseLayer::level ( ) const

inline

prepare()

void pulp::signal::drum::NoiseLayer::prepare ( double sample_rate )

inline

process()

double pulp::signal::drum::NoiseLayer::process ( double coloured )

inline

Next sample.

coloured is a sample from the voice's generator with its colour filter applied.

set_decay_ms()

void pulp::signal::drum::NoiseLayer::set_decay_ms ( double ms )

inline

set_level()

void pulp::signal::drum::NoiseLayer::set_level ( double level )

inline

trigger()

void pulp::signal::drum::NoiseLayer::trigger ( )
