Detailed Description

Base class for Clips that produce some kind of audio e.g.

WaveAudioClip or EditClip. This class contains the common functionality such as gains, fades, plugins etc.

If your source if dynamically generated override needsRender to return true. This will then trigger the rest of the render callbacks which should be used to generate the source and fill in any update messages etc.

If your source is static override getAudioFile to return the source file. Note that this may be changed by the UI so it is a good idea to also overrride sourceMediaChanged and getSourceLength to update properties accordingly when the source ProjectItemID is re-assigned.

Either way you must override getHash which should return a hash of the current source e.g. an AudioFile hash or hash describing the current render set-up of an Edit.

Member Function Documentation

pure virtual

Must return the length in seconds of the source material e.g.

the length of the audio file or edit.

Implemented in tracktion::engine::ContainerClip, tracktion::engine::EditClip, and tracktion::engine::WaveAudioClip.

◆ getAudioFile()

virtual AudioFile tracktion::engine::AudioClipBase::getAudioFile ( ) const

virtual

Returns the file used to play back the source and will get proxied etc.

Reimplemented in tracktion::engine::EditClip.

◆ markAsDirty()

This will be called on the message thread so should complete quickly, if your source needs some time consuming setup (e.g. loading Edits) then make sure your render job does this in its render thread.

Though a bit spaghetti, the ARA node generation will be handled elsewhere, the parent AudioTrack, for the sake of live-play.

Returns

False if something went wrong!

     It's possible no ARA-compatible plugins were found,
     or that ARA complained about something resulting
     in failure to set it up accordingly.
     Celemony's ARA is really flaky and touchy, so the latter
     is most likely!
