Member Function Documentation

◆ applyToBuffer()

void tracktion::engine::LevelMeterPlugin::applyToBuffer ( const PluginRenderContext & )

overridevirtual

Process the next block of data.

The incoming buffer will have an unknown number of channels, and the plugin has to deal with them however it wants to.

The buffer should be resized to the number of output channels that the plugin wants to return (which should be the same or less than the number of output channel names it returns from getChannelNames() - never more than this).

Implements tracktion::engine::Plugin.

Definition at line 62 of file tracktion_LevelMeter.cpp.

◆ canBeDisabled()

bool tracktion::engine::LevelMeterPlugin::canBeDisabled ( )

◆ deinitialise()

void tracktion::engine::LevelMeterPlugin::deinitialise ( )

overridevirtual

Called after play stops to release resources.

Don't call this directly or the initialise count will become out of sync.

See also: baseClassDeinitialise

Implements tracktion::engine::Plugin.

Definition at line 56 of file tracktion_LevelMeter.cpp.

◆ getName()

juce::String tracktion::engine::LevelMeterPlugin::getName ( ) const

overridevirtual

The name of the type, e.g.

"Compressor"

Implements tracktion::engine::Plugin.

Definition at line 27 of file tracktion_LevelMeter.h.

◆ getNumOutputChannelsGivenInputs()

int tracktion::engine::LevelMeterPlugin::getNumOutputChannelsGivenInputs ( int numInputChannels )

overridevirtual

This must return the number of output channels that the plugin will produce, given a number of input channels.

E.g. some might be able to do mono, so will return 1 if the input is 1, 2 if it is 2, etc.

The default impl just returns the number of items that getChannelNames() returns.

◆ getSelectableDescription()

juce::String tracktion::engine::LevelMeterPlugin::getSelectableDescription ( )

overridevirtual

Subclasses must return a description of what they are.

Implements tracktion::engine::Selectable.

◆ getTooltip()

juce::String tracktion::engine::LevelMeterPlugin::getTooltip ( )

overridevirtual

default returns the name, others can return special stuff if needed

Reimplemented from tracktion::engine::Plugin.

Definition at line 30 of file tracktion_LevelMeter.h.

◆ initialise()

void tracktion::engine::LevelMeterPlugin::initialise ( const PluginInitialisationInfo & )

overridevirtual

Gives the plugin a chance to set itself up before being played.

This won't be called concurrently with the process thread.

The sample rate and the average block size - although the blocks won't always be the same, and may be bigger.

Don't call this directly or the initialise count will become out of sync.

See also: baseClassInitialise [[ message_thread ]]

Implements tracktion::engine::Plugin.

Definition at line 35 of file tracktion_LevelMeter.cpp.

◆ initialiseWithoutStopping()

void tracktion::engine::LevelMeterPlugin::initialiseWithoutStopping ( const PluginInitialisationInfo & )

overridevirtual

Tells the plugin that the audio graph has changed but the plugin isn't being re-initialised - i.e.

it's being re-used, maybe by being moved to a different track, etc. This can be called concurrently whilst the plugin is being processed so implementations of it must be thread safe. [[ message_thread ]]

Reimplemented from tracktion::engine::Plugin.

Definition at line 41 of file tracktion_LevelMeter.cpp.

Definition at line 90 of file tracktion_LevelMeter.cpp.

◆ shoulMeasureCpuUsage()

bool tracktion::engine::LevelMeterPlugin::shoulMeasureCpuUsage ( ) const

finalvirtualnoexcept

Plugins can return false if they want to avoid the overhead of measuring the CPU usage.

It's a small overhead but with many tracks, the level meters and vol/pan plugins can make a difference.

Reimplemented from tracktion::engine::Plugin.

Definition at line 33 of file tracktion_LevelMeter.h.
