ImaAdpcmFormatConversionProvider

public static class ImaAdpcmFormatConversionProvider.DecodedImaAdpcmAudioInputStream

extends TSynchronousFilteredAudioInputStream

AudioInputStream returned on decoding of IMA ADPCM. An instance of this class is returned if you call AudioSystem.getAudioInputStream(AudioFormat, AudioInputStream) to decode an 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.
