Constructor Detail

WavMonoSampleWriter

public WavMonoSampleWriter(File aFile)
                    throws FileNotFoundException

Constructs the WavMonoSampleWriter for writing sound samples to a WAV file or stream.

Parameters:

aFile - The File where to write the CSV records to.

Throws:

FileNotFoundException - If the given file object does not denote an existing, writable regular file and a new regular file of that name cannot be created, or if some other error occurs while opening or creating the file.

WavMonoSampleWriter

public WavMonoSampleWriter(OutputStream aOutputStream)

Constructs the WavMonoSampleWriter for writing sound samples to a WAV file or stream.

Parameters:

aOutputStream - The OutputStream where to write the CSV records to.

Method Detail

withBitsPerSample

public WavMonoSampleWriter withBitsPerSample(BitsPerSample aBitsPerSample)

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

Specified by:

withBitsPerSample in interface BitsPerSampleAccessor.BitsPerSampleBuilder<WavMonoSampleWriter>

Parameters:

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

Returns:

The builder for applying multiple build operations.

writeNext

public void writeNext(double aSampleData)
               throws IOException

Writes the next samples, one sample for each channel. Provide one sample for mono audio, two samples for stereo audio and so on. In case you provide more or less samples than channels being supported by the writer, then it is up to the writer whether to duplicate the samples or calculate an average or the like.

Specified by:

writeNext in interface MonoSampleWriter<WavMonoSampleWriter>

Parameters:

aSampleData - The samples, one for each channel.

Throws:

IOException - thrown in case writing the sample caused an I/O related problem.

writeNext

public void writeNext(MonoSample aSample)
               throws IOException

Writes the next samples, one sample for each channel. Provide one sample for mono audio, two samples for stereo audio and so on. In case you provide more or less samples than channels being supported by the writer, then it is up to the writer whether to duplicate the samples or calculate an average or the like.

Specified by:

writeNext in interface org.refcodes.io.RowWriter<MonoSample>

Specified by:

writeNext in interface SampleWriter<MonoSample,WavMonoSampleWriter>

Parameters:

aSample - The samples, one for each channel.

Throws:

IOException - thrown in case writing the sample caused an I/O related problem.

getSamplingRate

public int getSamplingRate()

Retrieves the sampling rate from the sampling rate property.

Specified by:

getSamplingRate in interface SamplingRateAccessor

Returns:

The sampling rate stored by the sampling rate property.

setSamplingRate

public void setSamplingRate(int aSamplingRate)

Sets the sampling rate for the sampling rate property.

Specified by:

setSamplingRate in interface SamplingRateAccessor.SamplingRateMutator

Parameters:

aSamplingRate - The sampling rate to be stored by the sampling rate property.

withSamplingRate

public WavMonoSampleWriter withSamplingRate(int aSamplingRate)

Sets the sampling rate for the sampling rate property.

Specified by:

withSamplingRate in interface SamplingRateAccessor.SamplingRateBuilder<WavMonoSampleWriter>

Parameters:

aSamplingRate - The sampling rate to be stored by the sampling rate property.

Returns:

The builder for applying multiple build operations.
