Update APM Playback

ƒUpdate APM PlaybackTarget is Odin Pipeline

• Target
• Effect Id
• Delay

• Samples
• Return Value

Updates the specified APM effect's sample buffer for processing the reverse (playback) audio stream. The provided samples must be interleaved float values in the range [-1, 1]. The delay parameter is used to align the reverse stream processing with the forward (capture) stream.

• Node type: Callable function. Has execution pins and runs when it is reached in the event graph.
• Target: Odin Pipeline
• Menu category: Odin › Audio Pipeline
• C++: UOdinPipeline::UpdateApmPlayback

note

The delay can be expressed as:

delay = (t_render - t_analyze) + (t_process - t_capture)

where:

• t_render is the time the first sample of the same frame is rendered by the audio hardware.

• t_analyze is the time the frame is processed in the reverse stream.

• t_capture is the time the first sample of a frame is captured by the audio hardware.

• t_process is the time the frame is processed in the forward stream.
