## Topics

### Enqueuing sample buffers

[`func enqueue(CMReadySampleBuffer<CMSampleBuffer.DynamicContent>) async throws -> AVSampleBufferAudioRenderer.Receiver.EnqueueResult`](/documentation/AVFoundation/AVSampleBufferAudioRenderer/Receiver/enqueue(_:))

Suspends until the receiver is ready for more media data, then enqueues a sample buffer in order to render its contents.

[`func enqueueImmediately(CMReadySampleBuffer<CMSampleBuffer.DynamicContent>) -> AVSampleBufferAudioRenderer.Receiver.EnqueueResult`](/documentation/AVFoundation/AVSampleBufferAudioRenderer/Receiver/enqueueImmediately(_:))

Enqueues a sample buffer in order to render its contents, without waiting for the renderer to become ready for more media data.

[`enum EnqueueResult`](/documentation/AVFoundation/AVSampleBufferAudioRenderer/Receiver/EnqueueResult)

A value indicating the result of a call to `enqueue(_:)` or `enqueueImmediately(_:)`.

### Flushing the receiver

[`func flush()`](/documentation/AVFoundation/AVSampleBufferAudioRenderer/Receiver/flush())

Instructs the receiver to discard pending enqueued sample buffers.

[`func flush(fromSourceTime: CMTime) async -> Bool`](/documentation/AVFoundation/AVSampleBufferAudioRenderer/Receiver/flush(fromSourceTime:))

Flushes enqueued sample buffers with presentation time stamps later than or equal to the specified time. This method suspends until the flush is completed.

[`enum SuggestedFlushReason`](/documentation/AVFoundation/AVSampleBufferAudioRenderer/Receiver/SuggestedFlushReason)

Reasons the receiver suggests the client flush and re-enqueue.

### Observing rendering events

[`var renderingEventsAfterFinishedEnqueuing: some Sendable & AsyncSequence<AVSampleBufferAudioRenderer.Receiver.RenderingEvent, Never>`](/documentation/AVFoundation/AVSampleBufferAudioRenderer/Receiver/renderingEventsAfterFinishedEnqueuing)

A sequence of events that may occur when rendering after enqueuing samples has finished.

[`enum RenderingEvent`](/documentation/AVFoundation/AVSampleBufferAudioRenderer/Receiver/RenderingEvent)

Events that might require intervention after there are no more samples to enqueue, but before rendering has finished.
