Different vizzy beeps

I believe that there should be at least 2 more different sounds that vizzy can beep, that being square wave sounds and sawtooth waves. The two I have listed both sound drastically different to each other and can be used for warning beeps for different warnings as such, making a clear difference.

Such a small thing like the sound I think could make a huge difference.

Here's a sine wave (this is what we have currently)

Here's a square wave

Here's a sawtooth wave

As you can clearly hear, they are easily distinguishable and therefore I think something like this would be a good addition
