-tpink means use pink noise (default).
Pink noise is perceptually uniform noise - that is, it sounds like every frequency at once. If you can hear any tone it may indicate resonances in your speaker system or room.
-t2 means use sine wave.
-tsine means use sine wave.
-twav means to play WAV files, either pre-defined files or given via -w option.
You can pass the number from 1 to 3 as a backward compatibility.
