5.6.1 A-B Auditioning
For simple and quick auditioning use AB Mode. Control is via the A-B tab.
Clicking in the A or B columns will assign
a codec to the A or B audition channels. Clicking
in the B column adjacent to a selected A codec
will automatically set the B column to the input
signal (I/P). To revert to a codec for the B column,
click on a cell non-adjacent to the A codec.
The A-B buttons toggle
between the codec selected in the A column
and the codec (or input) selected in the B column.
This is ideal for critical listening tests.
The HIDE button makes the current selection
anonymous. The A-B buttons still toggles between the two column selections.
The BOTH button displays both of the two DIFF signals (the currently auditioning signal is
coloured green).
5.6.2 A-B-X Testing
For more detailed and statistical listening tests, use A-B-X mode (for the principles
behind A-B-X testing, there is a good Wikipedia entry). Select the A-B-X tab via the
down-arrow on the tab.
Unlike
hardware A-B-X systems, there is no switch delay
or switching glitches in this implementation.
The two A-B assignment columns
are used in a similar fashion to A-B auditioning,
but the column headers are now buttons.
There is also an additional button labelled X.
Although the three A-B-X buttons are like
mechanical ‘radio buttons’, repeatedly pressing
the same button will alternate between that
