What determines high frequency and low frequency? I know it's a dumb
question but I'm asking anyway.
May the Peace of God which passes all understanding guard your heart and
mind in Christ Jesus. God bless you!

Hi Bobby.
Q is calculated by the formula
Q = (center frequency)/((high frequency) - (low frequency)) Hopefully you
have punctuation announcement turned on for that.
Here's an example:
Q = 1000/(1750 - 750)
Q = 1
Another example
Q = 1000/(1100 - 900)
Q = 5
The higher the Q parameter, the narrower the affected band of frequencies.
There is no easy Q to octave correspondence.
Luckily, there are handy web tools for this and other audio calculations.
Here's an example.

If you want to really dig into the math, here's a great article.

and, for an explanation from Moulton himself on the relationship between HZ,
Q and octave, check out
