generating sounds

Archiver

I'd like to use FREQOUT to make my BS2 make a sound like a bell
ringing. It's for my circuit where the user has to select the right
buttons. If they select the right button, I want to make a sound
like what you hear on a game show when someone gets a right answer.
Kind of a "ding" sound. I'll also make a buzzer sound for wrong
answers, but I know how to do that.

Is it possible to make a "dinging" sound with the stamp? I don't
want to have to use an auxillary audio playback module or anything.
I'd like to only use the stamp. Also, is there some program I can
run on my PC to play the tones written in PBASIC, or do I have to
load them onto the stamp to hear them?

Thanks in advance for the help. You guys are extremely helpful.
I've learned so much stuff just from reading the archived messages

If you use FREQOUT and use two frequencies slightly off from one
another you will hear a fading-in/fading-out if played continuously.
This fading effect is the BFO (Beat Frequency Oscillation) between
the two frequencies. You can use this to your advantage to simulate
a 'Ding' by only allowing the duration of FREQOUT to last until the
BFO frequencies come together and fade out once. I have an example
of code to simulate a 'DING'...'DONG' used as a doorbell at the house
I can follow up with tomorrow.

Ooh, that sounds like exactly what I'm looking for. Thanks!
