frequency to note conversion questions about q

[djowel]

• How can I convert the frequency values ​​in range 0-1 returned by the get_frequency member function of the pitch_detector class into normal pitch values?

get_frequency does not return values ​​in range 0-1. It returns the actual frequency. Have you tried running the pitch_detector test? Here's the relevant code:

To convert frequency to pitch, you can use this:

hi @djowel

Thanks very much for your answer.

I set the sps parameter for pitch_detector incorrectly. When I replaced this to the sample rate of the input device, I started to get correct results. As far as I understand from the test codes, this means sample rate. Am I thinking right?

That is correct.
