public AlawFormatConversionProvider.FromAlawStream(AudioInputStream sourceStream,

Method Detail

convert

protected int convert(byte[] inBuffer,
                      byte[] outBuffer,
                      int outByteOffset,
                      int inFrameCount)

Description copied from class: TSynchronousFilteredAudioInputStream

Override this method to do the actual conversion. inBuffer starts always at index 0 (it is an internal buffer) You should always override this. inFrameCount is the number of frames in inBuffer. These frames are of the format originalFormat.

Specified by:

convert in class TSynchronousFilteredAudioInputStream

Returns:

the resulting number of frames converted and put into outBuffer. The return value is in the format of this stream.

convertInPlace

protected void convertInPlace(byte[] buffer,
                              int byteOffset,
                              int frameCount)

Description copied from class: TSynchronousFilteredAudioInputStream

Override this method to provide in-place conversion of samples. To use it, call "enableConvertInPlace()". It will only be used when input bytes per frame >= output bytes per frame. This method must always convert frameCount frames, so no return value is necessary.

Overrides:

convertInPlace in class TSynchronousFilteredAudioInputStream
