One of the many great things about Ultimate Racer is being able to customise sounds for various events. I've trawled the web to find more Murray Walker soundbites to add to those that come with the program, and edited them where needed e.g. to match the timing of my start lights.
I use the Windows speech synthesis for the first three events but the remainder are Murray Walker commentary and sound effects. The table below shows the mapping to audio files.
For users of Ultimate Racer who wish to use this sound scheme, I've zipped up all the audio files and the image above and you can download them all here.
