[alsa-devel] is 440 Hz the true harmonic wave
Is 440 Hz the true harmonic wave? Is there a constant for it in glibc, like M_PI?

440 Hz is a frequency, not a wave.
A single sine wave does not have overtones, so it is not possible to apply the term "harmony".
I do not understand what you mean with "true".
Is there a constant for it in glibc, like M_PI?
What would be the use of a definition like "#define HZ_440 440"?

I believe that 440 Hz is an approximation rather than true harmonic on it's pressure. Or am I wrong? Sine is harmonic in default arc.
thank you!
