Delegate CoreAudioCaptureDataAvailableHandler

Namespace

NAudio.Wave

Assembly

NAudio.MacOS.dll

Provides an event handler that provides the audio data captured by a CoreAudioCapture instance.

public delegate void CoreAudioCaptureDataAvailableHandler(ReadOnlySpan<byte> audioData, double currentTimeInSeconds, double firstByteAcquiredFromHALTimeInSeconds)

Parameters

audioData ReadOnlySpan<byte>

The span of bytes containing the capture data.

currentTimeInSeconds double

A HAL timestamp, in seconds, that indicate when the HAL started the I/O cycle.

firstByteAcquiredFromHALTimeInSeconds double

A HAL timestamp, in seconds, that indicate when the first byte of the currently provided audio data was retrieved.

Remarks

Note that the audioData parameter points to an arbitrary memory block provided by the HAL so that it's clients can retrieve the audio data from the hardware device; as such, just assigning the span to a field will later on cause memory corruption issues. So, provide your own allocated buffer and copy the data that the audioData parameter contains to your own buffer before the execution of the method reaches it's end.
