Class AbstractLineOutSampleWriter<S extends SoundSample,B extends LineOutSampleWriter<S,B>>

java.lang.Object

org.refcodes.audio.AbstractLineOutSampleWriter<S,B>

Type Parameters:

S - The SoundSample (sub-)type on which the SampleWriter implementation is to operate on.

B - The SampleWriter implementing this AbstractLineOutSampleWriter.

All Implemented Interfaces:

AutoCloseable, BitsPerSampleAccessor, BitsPerSampleAccessor.BitsPerSampleBuilder<S>, BitsPerSampleAccessor.BitsPerSampleMutator, BitsPerSampleAccessor.BitsPerSampleProperty, LineOutSampleWriter<S,B>, SampleWriter<S,B>, SamplingRateAccessor, SamplingRateAccessor.SamplingRateBuilder<S>, SamplingRateAccessor.SamplingRateMutator, SamplingRateAccessor.SamplingRateProperty, org.refcodes.io.RowWriter<S>

Direct Known Subclasses:

LineOutMonoSampleWriter, LineOutSoundSampleWriter

public abstract class AbstractLineOutSampleWriter<S extends SoundSample,B extends LineOutSampleWriter<S,B>>
extends Object
implements LineOutSampleWriter<S,B>

The AbstractLineOutSampleWriter provides a foundation means to write sound samples to a line-out device.

Constructor Detail

AbstractLineOutSampleWriter

public AbstractLineOutSampleWriter()

Constructs an AbstractLineOutSampleWriter.

AbstractLineOutSampleWriter

public AbstractLineOutSampleWriter(BitsPerSample aBitsPerSample)

Constructs an AbstractLineOutSampleWriter with the given BitsPerSample to use.

Parameters:

aBitsPerSample - The bits/sample to use when doing audio playback.

Method Detail

setBitsPerSample

public void setBitsPerSample(BitsPerSample aBitsPerSample)

Sets the bits/sample per channel for the bits/sample per channel property.

Specified by:

setBitsPerSample in interface BitsPerSampleAccessor.BitsPerSampleMutator

Parameters:

aBitsPerSample - The bits/sample per channel to be stored by the sampling rate property.

getBitsPerSample

public BitsPerSample getBitsPerSample()

Retrieves the bits/sample per channel from the bits/sample per channel property.

Specified by:

getBitsPerSample in interface BitsPerSampleAccessor

Returns:

The bits/sample per channel stored by the bits/sample per channel property.

toWavSample

protected long toWavSample(double eSampleData)

toLineOut

protected static SourceDataLine toLineOut(SoundSample aSoundSample,
                                          BitsPerSample aBitsPerSample)
                                   throws LineUnavailableException

Produces a line-out SourceDataLine instance for writing samples to.

Parameters:

aSoundSample - The SoundSample from which to get the according metrics.

aBitsPerSample - The preferred bits/sample.

Returns:

An instance of the SourceDataLine to which to write data.
