Re: [orca-list] Proposed patch for progress beeps



Howdy,

here you can generate a progressbar.

Hi all,, a dumb question:
Which programs can I use to test the progress bar?
Thanks and sorry for the dumb question!

Hey Nolan, all.

Could you please attach the patch to
https://bugzilla.gnome.org/show_bug.cgi?id=758328? Ditto for anyone else
interested in tweaking the progress bar beeps. If you all can reach
consensus, I'm happy to commit the agreed-upon experience.

Thanks!

Hey,

So I had some of the same issues with progress bar beeps that I did with
NVDA. As an experiment, I whipped up this patch.

Basically, according to my non-coffee-fueled back-of-napkin
calculations, the current implementation starts progress bar beeps at a
few hundred Hz and scales them up to something like 2100. I don't
objectively know what 2.1 KHz sounds like, but I do have some objective
notion of what an octave sounds like, and just as a sighted person
doesn't have to think about how far along a progress bar is, I think we
should have the same convenience.

This patch starts progress bar beeps at middle C and ramps the
progression up an octave linearly. I initially had a logarithmic
implementation but found it more confusing than I thought. Perceptually
the progress bar appeared to move quickly then slow down, which is
consistent with the numbers. I haven't tested this out with faster
progress bars yet so there may be some benefit to logarithmic, but one
thing at a time.

We may also be able to drop the volume-scaling code if we're not ramping
the frequencies up above 1 KHz, but I haven't tested that yet.

Thoughts?
