<p>Splits one interleaved multichannel audio stream into many mono audio streams.</p>
<p>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.</p>
<p>In most cases a queue and an audioconvert element should be added after each source pad
before further processing of the audio data.</p>

contain the original channel positions. This can be used to correctly
interleave the output again later but can also lead to unwanted effects
if the output should be handled as Mono.</p>
