How to produce sound

[yllis]

I'd like to add a tune to my project. For some reason I can't find how to do this.
And I don't want a really complex system like in the SDMMCWavPlayer-example.

I'm trying to find a simple way to create a tune.
I assume it is possible to write a frequency and duration for every note? What would the code look like?

And a second question:
Is it possible to convert a sound to some format and just load it in to the pic? I saw something like this done in this page:
http://www.romanblack.com/picsound.htm
Would this work? And if yes, then how?

Thank you already in advance.

The quality is poor.

So then how do you make a pic give out sound?

but thanks for the comment Norm..

Given the limitations of an 8bit PIC so far as queuing and raw processing power, getting good quality sound will be difficult.

For just any sound, connect a PWM pin of the PIC to a speaker and you should be able to produce tones. (I've not yet tried this myself, but it's on my eventual 'to do' list.)

I believe you will need a SD wav player if more than a second or two of recorded sound.
Steve's SDMMCWavPlayer is good or to do a port of code based on Steve's earlier work see PIC iPod wav player.
