The album features a double quartet, one in each stereo channel.
The three new 24 hour stereo channels are expected to go on air by the end of 2006.
The idea of pooling both stereo channels to gain increased power is not new.
On the CD version the left and right stereo channels reversed.
This means that the voice, as part of the music, has equal volume on both stereo channels and no phase difference.
The stereo channels separate, opening a cramped room into a performance hall.
Note that only one stereo channel is used - it doesn't matter which.
It typically includes more than just the left and right stereo channels.
There are two analog low pass filters, one for each stereo channel.
