Newbie question - Pic possible uses for sound

[ma9]

Hi, I received yesterday 3 sample PICs from microchip, I'm reading the documentation about these microcontrollers...

I've read that PIC has a 10bit AD converter but not a DA converter. I thought that putting a DA converter after a PIC may make it possible to use it ad a sound generator or DSP, isn't it? Does it work fast enough? Is it possible to code it for making a filter, or a wave oscillator.. or perhaps both of them in the same device?

I know that 10bits are not that much but it can be useful for a noob to make some experiments..
