- * Splits one interleaved multichannel audio stream into many mono audio streams.
- * 
- * This element handles all raw audio formats and supports changing the input caps as long as
- * all downstream elements can handle the new caps and the number of channels and the channel
- * positions stay the same. This restriction will be removed in later versions by adding or
- * removing some source pads as required.
- * 
- * In most cases a queue and an audioconvert element should be added after each source pad
- * before further processing of the audio data.
