What else do I need to know about the basis of TrikTraks and Wigout?

Not much. Remember that the frequency is the inverse of the waveform duration:

$$frequency~=~sampling\_rate~/~waveform\_duration$$

$$waveform\_duration ~ = ~ sampling\_rate ~ / ~ frequency$$

And also that the volume is

$$decibels~=~20~*~log_{10}(maximum\_displacement)$$

$$maximum\_displacement~=~10^{decibels/20}$$

So, if you wanted to create the frequency of 660 hertz (the E above A-440) and your sampling rate was 44100

66.81 = 44100 / 660

You would need a waveform duration of 67 samples (rounded up). If you wanted that waveform to have a loudness of 72 dB:

3981.07 = 10^72/20

Its maximum displacement would have to be 3981.
