5.6 A-B Auditioning and A-B-X Testing (A-B Tab)

5 THE PRO-CODEC PLUG-IN

5.6 A-B Auditioning and A-B-X Testing (A-B Tab)

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
