Re: How to test sound freq?

@namespace

I have made tone generator, using DSound buffers and simply cos(2*pi*f*t)
and I know what frequency is.

I've looked around and I've found Goertzel's algorithm, but I didn't use
it because of DTMF structure (as I remember, it was the sum of two sin
signals). You say that I can detect tone frequency with that algorithm?

@Vladimir V.

I think it is not possible for me to develop frequency counter in C++ :(.

Thank you, both.
