nothing happens when you press the SOUND button.

The SoundRacer sounds are recorded and prepared by a professional sound designer. 
 
For customers who want to try developing their own sounds we provide this short description 
 
A complete sound contains four different sound files: 
idle.wav            1000 RPM idling                         sampling frequency 11k (11025 Hz) 
onlow.wav       3500 RPM acceleration            sampling frequency 22k (22050 Hz) 
onhigh.wav      7000 RPM acceleration            sampling frequency 22k (22050 Hz) 
offlow.wav      4000 RPM deceleration            sampling frequency 22k (22050 Hz) 
 
Other rpm figures can be used but the proportions should be the same 1:3,5:7:4
