Welcome back. Some great suggestions here.

You've been away too long. Bugs are on Launchpad now.

I couldn't make this happen. Can you reproduce it?

Hard to say. Sound problems could have countless causes.

Yes it should.

Absolutely. I don't like having to use the mouse all the time. You can tab
between the sliders and use left and right keys but if you know the specific
value you want there ought to be a way to put it in. The trouble is the
interface then starts to get rather cluttered.

I think we could do this for a future release. The mixer view now lets you
increase the volume so that the factor is greater than 1.0. You can see the
bigger levels in the VU displays but the waveforms don't reflect the
amplification. The same applies if you use an amplify effect. I'd like to
just right-click on a too quiet audio clip (duff interview recordings do
happen) and select normalise and have Jokosher calculate the optimum
amplification for me. Then display the amplified waveform so you can see
that it's altered. I think we already have enough level info about a clip to

It's probably possible with a bit of re-engineering but we'd have to think
carefully to avoid overcluttering the UI.

I still always drag to select. It's what every other app I use does.

An excellent idea. I love mouseover tips that give you useful info that
avoid having to click through umpteen levels to get what you want.
