I'm using the roImageCanvas which doesn't automatically generate the standard sounds associated with navigation. Is there a system call that I can use to generate the sounds used for standard navigation?

AFAIK, there is no direct way to do this with the current SDK.

Possible hacks and workarounds were discussed here: viewtopic.php?f=34&t=35581

Nice onomatopoeia though! 🙂

If you want to try to fake it up (which is only useful currently if you can deal with up to a second delay), here's a few pointers:

• The audio player component only deals with MP3s, so convert sounds to that.


• There' sometimes a problem if the sound is less than a second, so pad with silence to make it a minimum of a second long.


• Make sure you don't let the audio player component go out of scope before it's finished playing, or you'll got a partial sound or no sound at all.

Thanks to those who replied.

Agree there are issues with very short sounds. I've had to pad some of my sound clips.

The suggestion to do a 'PutMessage' is quite diabolical. I love it. However that command doesn't seem to be supported anymore 😞

Often wondered about pausing a looping clip. Like the idea, but envision that eventually the pause location would get out of sync with sound, thus the start of play might occur in the middle of the sound. Not sure if there are workarounds...

Fundamentally the issue I face is with performance. My applications have lots of navigation (moving cursor around a puzzle...) so responsiveness to navigation is critical, and this takes a hit when I start playing a sound. The native 'be-doop' sounds don't seem to incur this performance degradation. Ho-Humm. Maybe this will be supported in the future?

Thanks again,
Fred

Based on what Roku has said they are planning to add (from requests for this in the past), I would say it's very likely they've got something planned to help with this problem.

Is there any update on this? May be in 3.0 we can make "key handling sounds" in roImageCanvas?

Check out roAudioResource in the v3.0 BrightScript Reference.
