Constructor & Destructor Documentation

◆ AudioContainerPcm()

Async::AudioContainerPcm::AudioContainerPcm ( void )

Default constructor.

◆ ~AudioContainerPcm()

virtual Async::AudioContainerPcm::~AudioContainerPcm ( void )
virtual

Destructor.

Member Function Documentation

◆ filenameExtension()

virtual const char * Async::AudioContainerPcm::filenameExtension ( void ) const
inlinevirtual

Get the standard filename extension for the audio container.

Returns
Returns a string containing the filename extention, e.g. wav

Implements Async::AudioContainer.

Definition at line 155 of file AsyncAudioContainerPcm.h.

◆ flushSamples()

virtual void Async::AudioContainerPcm::flushSamples ( void )
virtual

Tell the sink to flush the previously written samples.

This function is used to tell the sink to flush previously written samples. When done flushing, the sink should call the sourceAllSamplesFlushed function.

Reimplemented from Async::AudioSink.

◆ mediaType()

virtual const char * Async::AudioContainerPcm::mediaType ( void ) const
inlinevirtual

Retrieve the media type for the audio container.

Returns
Returns a string representing the media type, e.g. audio/wav

Implements Async::AudioContainer.

Definition at line 146 of file AsyncAudioContainerPcm.h.

◆ writeSamples()

virtual int Async::AudioContainerPcm::writeSamples ( const float * samples,
int count )
virtual

Write samples into this audio sink.

Parameters
samplesThe buffer containing the samples
countThe number of samples in the buffer
Returns
Returns the number of samples that has been taken care of

This function is used to write audio into this audio sink. If it returns 0, no more samples should be written until the resumeOutput function in the source have been called.

Reimplemented from Async::AudioSink.
