WavFileWriter

public WavFileWriter(String fileName,
 AudioFormat audioFormat)

Method Details

writeSingleChannel

public static boolean writeSingleChannel(String file,
 AudioFormat format,
 double[] doubleArray)

Writes an array of double values to a WAV file. This method only writes single channel data.

Parameters:

format - AudioFormat object describing the desired file

doubleArray - the array of double values to save

Returns:

boolean indicating success or failure of the write

write

public boolean write(double[][] doubleArray)

Writes an array of double values to an existing WAV file. This method writes single and multi-channel data. This method writes the data with any bit depth, depending on how the wav file object was created using an AudioFormat.

Parameters:

doubleArray - the array of double values to save. Note that this is defined as a 2D array. If a single-channel 1D vector is passed, it doesn't seem to be a problem.

Returns:

boolean indicating success or failure of the write

append

public boolean append(double[][] rawData)

Append data to a file which may or may not be closed already.
If the file is still open then this simply calls the write function, otherwise it has to reopen the file.

Parameters:

rawData - Raw data to write. Must match audio format file was opened with.

Returns:

true if write was OK.

write

public static boolean write(String fileName,
 float sampleRate,
 double[][] doubleArray)

Writes an array of double values to a WAV file. This method writes single and multi-channel data. This method always writes the data as 16-bit. It shoul dbe used only for one off writing of short files.

Parameters:

sampleRate - The sample rate of the raw acoustic data

doubleArray - the array of double values to save. Note that this is defined as a 2D array. If a single-channel 1D vector is passed, it doesn't seem to be a problem.

numChannels - The number of channels to save

Returns:

boolean indicating success or failure of the write

close

public void close()

Overrides:

close in class WavFile

getFileFrames

public long getFileFrames()
