Each channel contains a synthesized human voice that announces the
name of the channel, so that a reviewer can, by simple inspection,
confirm the expected channel order. This will be particularly useful
when automatic channel reordering is performed.

The contents of each channel could be changed to a single tone with
each channel assigned a different tone, e.g. 1 to 6 kHz. This might
make the files shorter.
