Spybot's are capable of an incredible range of sounds. They have 64 pre-programmed sounds that can be called by number and room for an additional 16 user defined sounds (maximum size 63 bytes each). We won't be looking at defining our own sounds today. Instead we'll just look at making sounds and using those 64 pre-programmed sounds.

Let's start with the pre-programmed sounds. If you take a look in globals.h (it's in Spybot/include) you'll find that someone has gone to the trouble to provide names for each of the 64 sound sequences. For this example we can use the names as a guide use the numbers to make the sounds. So here's an example program:

task main()
{
PlaySound(41);
Wait(540);
}

This will play sndDizzy. Note the use of wait so we can actually hear the sound before the program closes down. To play any of the available sound sequences just replace 42 with the relevant number download and enjoy. To stop the current sound you can use MuteSound(). Too easy really and I imagine you could create programs for the next 10 years without even thinking about making your own sequences. But you can create and play your own sequences using PlayTone. All you need to use PlayTone is to supply a frequency and a duration (in that order). Here's how:

PlayTone(440, 50);
wait (50);

Repeat these two lines with variations in frequency and duration and you and your Spybot can make beautiful music together. The documentation provides the following chart to assist would be composers.
