I think this is a valid request. We could also consider lowering the pitch of the beep a bit?

A few thoughts:

• This ticket deals with the beep that is played whenever capitalization is encountered when the Beep for capitals check box part of the Voice Settings dialog is checked.
• It is highly unlikely that a proper .wav sound scheme will be introduced since this may cause performance slowdowns as noted by @Brian1Gaff in the ticket body.
• It is highly unlikely that the current beep will be revised keeping in mind of our lack of success in revamping other NVDA audio cues despite investment of significant time and resources.
• Therefore, what we could do to address this request is (a) reduce the volume of the beep and/or (b) reduce the pitch of the beep.
• Another ticket already discusses the implementation of an audio manager which would allow for the customization of the volume of NVDA sounds. If that ticket is broadened so as to encompass tones and beeps, then (a) of the previous point gets effectively resolved. If we further extend that other ticket's scope to include setting a custom pitch for these tones and beeps (and maybe NVDA sounds also), then (b) of the previous point also gets effectively resolved.
• Still, although an extensive audio manager would effectively resolve this ticket, the default state of the capitalization indicating beep requires to be changed. @LeonarddeR mentions in Have a selection of sounds for caps #931 (comment) that reduction of the beep's pitch should suffice. From a earphones user's standpoint, I would say that the beep's volume might also need some reduction.
• In conclusion, whether the volume or the pitch (or both) of the beep requires adjustment is up to debate, because the audio manager should only serve as a supplement, IMHO.

Please note that the 'other ticket' concerning an 'audio manager' as I mentioned in #931 (comment) is #1409.
