The quality is what it is I'm afraid.

Which pin are you using for output?

[tjodork1960]

digital IO pin 3 which is the 4th from the end

[jscrane]

Please try digital I/O pins 9 or 10 instead, I think pin 3 has a much lower PWM timer resolution: this is a hardware issue.

Please also read this document which describes how PWM is used in this library.

I tried pin 10 but it doesn't really sound much better.
I need to confirm .... can I output this right to an amplified speaker ? there was some mention of a resistor and capacitor...are they necessary ?
