Hello! I was wondering if someone here could give me advice. I want to play sounds with PsychPortAudio. The goal is to have simple tones of different frequencies that play continuously when the mouse hovers over specific areas on the screen. This is very simple when using sound(). For example: if…

Something along the following, assuming you have 3 “zones” each of which needs a different sound. This only stops-fillbuffers-starts playback if the zone is changed: oldzone = -1 zone = -1 while 1 [x,y] = GetMouse(window); zone = -1; if "mouseposition x,y is in zone 1" zone = 1; end …

I found something that seems to explain my question already, haven’t tried it yet, but looking very promising. Sorry for the spam! [image] Re: continuous sound output with psychtoolbox Hi, i'm forwarding this to the psychtoolbox forum in case it is of general inter…

There’s a much simpler solution: In the PsychPortAudio(‘Start’, …, repetitions) command, set repetitions to 0 for infinite looped playback. Sound will play and repeat without a gap until you call PsychPortAudio(‘Stop’, …); If you make sure that the sound vector you specify with ‘FillBuffer’ fits a n…

Wow, great, thanks! That’s much better! I have a new problem though: if xMouse == 200 && yMouse == 200; PsychPortAudio('FillBuffer', paHandle, tone1); startTime1 = PsychPortAudio('Start', paHandle, 0); else PsychPortAudio('Stop', paHandle); end This leads to Matlab crash…

What do you mean with crashing? What you would want in your case is check mouse position and only do a ‘Stop’, ‘Fillbuffer’, ‘Start’ sequence if the mouse position changes from one target area to another one.

Hello again! I am sorry to bother you again but I am not successful with the thing I was trying to achieve. I have tried different options. Option 1: if xMouse == 200 && yMouse == 200; PsychPortAudio('FillBuffer', paHandle, tone1); startTime1 = PsychPortAudio('Start', paHandle); el…

Thank you! I had tried an approach like this before but I see now that I made some mistakes when I did it, so I will try to implement your suggestion and see! I think that it could work. I will also consult BasicSoundScheduleDemo.m with maximum attention. :slight_smile: Thank you very much for your…

It’s working!! Thanks so much!
