I’d like to use the Spark to generate some audio frequency signals. PWM would be fine but I need to go well above the 500Hz of the AnalogWrite() function. The microprocessor has the speed and timing functions to modulate at say 20 or 40kHz but I guess this would be too fast to sit inside the loop()…

Have you seen this thread were @BDub makes some music?

I believe that the tone function has been in for some time now.
