Estimate fundamental frequency of audio signal - …
https://www.mathworks.com/help/audio/ref/pitch.html
f0 = pitch (audioIn,fs) returns estimates of the fundamental frequency over time for the audio input, audioIn, with sample rate fs. Columns of the input are treated as individual channels. example f0 = pitch (audioIn,fs,Name,Value) specifies options using one or more Name,Value pair arguments. example
Finding Fundamental Frequency of an Audio Signal
https://www.mathworks.com/matlabcentral/answers/644508-finding-fundamental-frequency-of-an-audio-signal
I have been trying to find the fundamental frequency of an F chord, but the frequency I am finding is 220 Hz, which is the fundamental frequency of an A chord. My main struggles have been with the "pwelch" function.
Fundamental frequency (F0) - Introduction to Speech ...
https://wiki.aalto.fi/pages/viewpage.action?pageId=149890776
Typically fundamental frequencies lie roughly in the range 80 to 450 Hz, where males have lower voices than females and children. The F0 of an individual speaker depends primarily on the length of the vocal folds, which is in turn correlated with overall body size. Cultural and stylistic aspects of speech naturally have also a large impact.
Calculation of mean fundamental frequency of audio …
https://stackoverflow.com/questions/49179128/calculation-of-mean-fundamental-frequency-of-audio-sample
The audio signals you're looking at are complex signals likely with many sine waves involved. Fundamental frequency is referring to the lowest frequency that is detected . I imagine that the mean fundamental frequency is the average of all the frequencies that were detected in the signal.

audio - How to get fundamental frequency of a signal …

It looks like you have about a 440 Hz signal, but this is clearly far from a "single pitch" as the shape is far from a sine. Just from inspection we can see that the second harmonic is particularly strong. It may be so strong that this "note" is perceived to be 880 Hz instead of …
Fundamental Frequency Estimation from Spectral Peaks ...
https://www.dsprelated.com/freebooks/sasp/Fundamental_Frequency_Estimation_Spectral.html
We assume here that the signal is periodic, so that all of its sinusoidal components are harmonics of a fundamental component having frequency . (For inharmonic sounds, the perceived pitch, if any, can be complex to predict .) An approximate maximum-likelihood-detection algorithm 11.1 consists of the following steps: Find the peak of the histogram of the peak-frequency …
