Asset­Audio

⚠️ This type is unstable and may change significantly in a way that the data won't be backwards compatible. An audio file, stored as-is (.aac, .flac, .m4a, .mp3, .ogg, .wav).

The audio starts playing at the time it was logged, so log it on a temporal timeline (duration or timestamp) at the point where playback should begin. The viewer plays it while time is playing, in an views.AudioView.
