there is two main ways of defining this, and it will depend on the version you are using.
1) (For older versions of TD) At the start of a level it plays a set sound, for example at the start of round 3 you wish it to play 100/200, this way is fine providing you don't change your structure around.
2) (For current version (3) play a sound at the start of each level, which matches the current blinds/antes. This way allows you to have multiple structures and no need for different events files.
for option 2 see the first thread, for option 1 see the second thread.

Just for clarity, the trigger can be either <A Level Starts> or <The clock ticks> if you use the latter, you need to specify either secondsElapsed or secondsLeft in your conditions. We will help you with conditions once you have decided what route you wish to take.
