FAQ

Can I suggest a new tool?

Yes. Include what the tool does, the formula/logic, and why existing tools don't work. If it solves a real live sound problem, it'll be considered.

I found a bug / wrong formula.

Describe the tool name, what you input, what you got, what you expected. Screenshots help. The fix will be applied and you'll be credited if desired.

Can I use these tools commercially?

Yes. They're free for any use. No attribution required (but appreciated). The formulas are physics. Nobody owns them.
