Re: [Audacity-devel] Linking changes!

[James C. <cr...@in...>]

Wow!

Just tried this out, and it looks good.

I think it is going to need feedback and tweaking of details from actual 
use.  I know you hoped to avoid that by choice of a clear definition of 
what should happen, but that is just how it is with new GUI ideas.  At 
least it should require much less iteration than starting from a less 
well thought out starting point would.


- In linking mode generate may or may not move audio - it depends on the 
size difference between the selection and the resulting Audio.  That 
looks correct to me, but I can see some users being puzzled at audio 
moving when they are generating audio at the end of an existing track 
and silence gets inserted in the track above.  Possibly a refinement is 
that the synchro selection is empty if no audio would be moved in the 
normally selected tracks, i.e. when making changes at the right end of 
tracks.  Not sure about this.  What do you think?
- I was surprised that a change speed (slower) changed speed in the 
synchro tracks too, rather than adding silence - though I can see the 
sense in it because we don't have that option when changing speed (faster).
- A minor tweak to the chain-link background is to start the image not 
at zero but at     internal position = (xPosition mod bitmap-width).  At 
the moment extending a selection left the chain links move, extending it 
right they don't.


Anyway, after a little getting used to it is very usable.  I like this.
