NOTE: When flashing the ATtiny at 16Mhz the files play a bit to fast. You can flash a 8MHz bootloader, but this requires you to speed up the sound files times two. This seemed to sound better..but yeh...you already know what it is... NOTE: When flashing the ATtiny at 16Mhz the sound files seem to play a bit fast. You can flash a 8MHz bootloader, but this requires you to speed up the sound files times two ('-speed 2'). This IS required when using an ATtiny85 10pu (runs at max 10Mhz).
