Here (for once) we do agree :-) There's probably no worse way
to show what a compressor is doing than showing the input and
output waveforms. A simple bargraph showing the current gain
- or better, the gain range over a short period - will do fine.
I've been demoing high end mixers (Digico) to experienced sound
engineers for some time. These mixers can show a graphical
representation of the EQ etc. The first thing these potential
customers ask is if those displays can be disabled - they just
don't want them.
Good UI design for audio apps means something entirely different:
- Something you can look at for extended periods. This means color
schemes that don't strain your eyes, the right amount of detail,
and nothing that becomes distracting by moving or flashing all
the time without providing essential information.
- A layout that is logical to someone who understands what an app
or plugin is doing. A clear distinction between things you set
up once and forget and those that you may want to adjust more
- A presentation that allows you to check if things are what you
expect they are at a glance, and even without being aware of it.
- The ability to find anything you'd need routinely without going
through menus, dialogs, or having to move or resize windows.
If you have to modify the display significantly in order to find
some control or action, it should be possible to return to the
previous one with just a single action.
- Showing correct and useful information rather than eye candy.
