Sorry this took so long. Couldn't get motivated. But, gettin' back
into the swing now.
Anyway, it was good that I looked away for a bit as its only gotten
"better" (well, according to me anyway ;-)).
Why has it gotten better? I'm glad you asked and here's a couple of
1) That darn flashy cursor is gone (sorry Dominic...;-))
2) The play/record indicators do not stick around after stopping
3) The cursor does not disappear in certain cases
4) The scrollbars are back in Linux (nobody noticed???)
5) Speed baby speed!!! (Okay, maybe not THAT much, but a little)
I did some VERY VERY unscientific testing on the Mac to see if
the changes made any difference during normal playback. I played
back a 1 minute song using 1.3.0b and it took 14.8 CPU seconds
according to Activity Monitor. I did the same thing with these
new changes and it took only 10.2 CPU seconds.
Big deal right?
Give this a try...
Load up your favorite activity monitor (Task Manager under Windows,
Activity Monitor on the Mac, Ktop? on Linux) and start Audacity 1.3.0b.
Open or create a new project with a good minute or so worth of audio.
Arrange the windows so you can see the Audacity window and the monitor at
the same time.
Click the mouse near the beginning of a track.
Press and hold the right arrow.
Watch the monitor to get an average CPU utilization guesstimate.
Now, do the same thing with these new changes and see what you get.
On a Dual 2.8Ghz Xeon box with WinXP, I go from about 19% with 1.3.0b down to 2%.
On a Dual G5, I go from about 90% down to 14%!
It may not seem like too much of a big deal to you mousers out there,
but when keyboarding on less powerful machines, that CPU savings should
make Audacity feel a fair bit smoother.
Anyway, have fun and let me know if I broke anything as I'm sure I have
BTW: Have I mentioned that the Apple GUI has yet to cause me any
headaches? That darn thing just works like you expect it to and is
just about as smooth as you can get.
