Member Enumeration Documentation

◆ Passthrough

enum class Nodes::AudioLooper::Node::Passthrough

strong

Enumerator
None	The input is never heard, in any mode.
Record	Heard while recording and overdubbing; playback is the loop alone.
Full	Always heard, mixed over the loop during playback.

◆ Restart

enum class Nodes::AudioLooper::Node::Restart

strong

Where the loop is read from when the mode changes.

Order matters: the first is what the object did before there was a choice.

Enumerator
Always	Every change of mode reads the loop from its beginning again.
Recording	Only a recording does; playing and overdubbing carry straight on.

Member Function Documentation

◆ enterMode()

void Nodes::AudioLooper::Node::enterMode	(	LoopMode	m,
		Restart	restart
	)

inline

Taking up a mode. A recording always starts its buffer again – there is nothing yet to carry on from. Whether playing and overdubbing do is what the Restart setting is for: reading the loop from the top on every change jumps, which is heard when overdubbing hands over to playing.

◆ silence()

void Nodes::AudioLooper::Node::silence	(	int64_t	first_pos,
		int64_t	samples
	)

inline

Outlet buffers come from a pool and are resized, not cleared: writing nothing leaves the previous tick's audio in them.
