At the very least that seems to mean the pin is being toggled 4x on the AtTiny for every 1 time its toggled on the Arduino. How that translates into higher quality audio, I'm not sure.
At 64mhz, 10bit is doable though.
The standard Arduino Atmega chips have a 16-bit PWM ability

excuse my stupidity. the link provided http://elm-chan.org/works/sd8p/report.htmlwhat software do you need to view the source codes?and can this be done with the arduino? or is there someway the arduino can view this code?
