Details:
The sound function seems to stop the sound playback too early. This shows up
espacially with short sounds below one second. I guess that the sound length
is shortened by around 200 milliseconds.
Attached there is a small function for creating configurable beep patterns. It
is suitable for testing this behavior. See inline documentation for usage.
The following call should play two short beeps a lower and a higher one. The
second beep in the example is not played on my windows system:
beepcode([700,100;1400,200])
When adding a time of silence to the end of the beep sequence the second beep
is played depending on the length of silence:
beepcode([700,100;1400,200;0,50])
beepcode([700,100;1400,200;0,100])
beepcode([700,100;1400,200;0,150])
beepcode([700,100;1400,200;0,200])
beepcode([700,100;1400,200;0,300])
