ipsk.io.InterleavedChannelRoutingInputStream

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable

public class InterleavedChannelRoutingInputStream
extends FramedEditingInputStream

Edits channels (interleaved data) from underlying stream. The stream must have an interleaved channel format, for example frameSize=8 bytes, channels=4 (samplesize=2 bytes): fr0ch0sb0,fr0ch0sb1,fr0ch1sb0,fr0ch1sb1,fr0ch2sb0,fr0ch2sb1,fr0ch3sb0,fr0ch3sb1,fr1ch0sb0,fr1ch0sb1,fr1ch1sb0,fr1ch1sb1,fr1ch2sb0,fr1ch2sb1,fr1ch3sb0,fr1ch3sb1 fr: frame ch: channel sb: byte of sample A assignment array of {1,3} edits the stream to: fr0ch1sb0,fr0ch1sb1,fr0ch3sb0,fr0ch3sb1,fr1ch1sb0,fr1ch1sb1,fr1ch3sb0,fr1ch3sb1 The resulting stream has two channels.
