Detailed Description

Handles the recording logic for the application.

This class is responsible for managing the recording process, including handling recording events, creating new regions, and managing automation points. It uses a queue to process recording events in a separate thread, and provides methods for starting, pausing, and stopping recording.

The class is designed to be thread-safe, with a binary semaphore to ensure that only one thread can access the recording logic at a time.

Member Typedef Documentation

◆ Position

using RecordingManager::Position = zrythm::dsp::Position

Definition at line 41 of file recording_manager.h.

Constructor & Destructor Documentation

◆ RecordingManager()

RecordingManager::RecordingManager ( QObject * parent = nullptr )

Creates the event queue and starts the event loop.

Must be called from a GTK thread.

Member Function Documentation

◆ handle_recording()

void RecordingManager::handle_recording	(	const TrackProcessor *	track_processor,
		const EngineProcessTimeInfo *	time_nfo )

Handles the recording logic inside the process cycle.

The MidiEvents are already dequeued at this point.

Parameters

g_frames_start	Global start frames.
nframes	Number of frames to process. If this is zero, a pause will be added. See RECORDING_EVENT_TYPE_PAUSE_TRACK_RECORDING and RECORDING_EVENT_TYPE_PAUSE_AUTOMATION_RECORDING.
