ImaAdpcmFormatConversionProvider

public static class ImaAdpcmFormatConversionProvider.EncodedImaAdpcmAudioInputStream

extends TSynchronousFilteredAudioInputStream

AudioInputStream returned on encoding to IMA ADPCM. An instance of this class is returned if you call AudioSystem.getAudioInputStream(AudioFormat, AudioInputStream) to encode to a IMA ADPCM stream.

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.
