16-bit DAC too arduino for nice sinus waves

http://www.arduino.cc/playground/Code/PCMAudio

in the reference of this code there is this article: gonium.net » Blog Archive » I will think before I code…

here they are working with the interupt library, is this library possible too use too get the 16Mhz too another clock speed. I'm also asking myself, if it's minimal 9,2 Mhz, can i not use the 16 Mhz full speed clock of the arduino or will that be an overkill for the DAC?

Is there anybody capable and willing too write an I2S library, i would like too help for as far as i can, and i came pretty far on my one i think (with a lot of help, from you guys ;)) I don't know how difficult it really is; what problems will accure in the future :slight_smile:
