[Audacity-devel] Play looped & Play One Second improvements & Scrolling in general

[Markus M. <me...@me...>]

Hi,

I'm in the progress of implementing a "play looped" function (plays the
selection in a loop, and even works for very small portions of Audacity
flawlessy). This will require some not-so-minor changes to AudioIO. I'm
about 70% finished with this, but haven't checked in anything.

Since this is a feature which has been requested numerous times: Should
we have a button for this (f.e. a "[>[>" button near the play button)?
Or should I just assign it to some key for now, for example Strg+Space
(and Strg+[Play button])?

Dominic, if you're concerned about the changes to AudioIO, do you want a
patch for preview before I check this in?

I would also like to add the improvements suggested by Juhana regarding
the "Play One Second should not do AutoScrolling" behaviour.

I also suppose we should add Juhana to the contributors list (in "other
contributors"). Although his suggestions are discussed controversely, he
often gives good impulses.

While I'm at it, does anyone have some good idea how we can improve
autoscroll? The current scrolling logic (page-wise) looks really crappy.
Any ideas on how this could be implemented to implement continuous
scrolling without eating up too much CPU time?
