Beep frequency

Solves Objective: Find out what frequency the beeps are

What is this?

This objective requires us to find the frequency that the beeps for the tabs are using measured in hertz. This is building off of the same result from Finding Functions Via Sound

Answer

If we analyze this block

mov     edx, 3B6h       ; dwDuration
mov     ecx, 0C8h       ; dwFreq
call    cs:Beep
mov     cs:dword_140156D58, 13h

We see that the value of the dwFreq argument is 0x0C8. Converting this to decimal we have 200 as the result.

Summary

The answer to this is that this function, as well as all other beeps (which we can verify by analyzing other blocks of tabs that use the beep function or condition) have a frequency of 200 hz.
