first off all, let windows use subsystem of linux, you can go here >>> https://www.howtogeek.com/249966/how-to-install-and-use-the-linux-bash-shell-on-windows-10/

and then go to firehol netdata https://github.com/firehol/netdata/wiki/Installation#x86_64-pre-built-binary-for-any-linux

and follow this step

1. open windows+R and type bash
2. do at root(optional)
3. lookinto "x86_64 pre-built binary for any Linux"
4. DO this "#bash <(curl -Ss https://my-netdata.io/kickstart-static64.sh)"

Experimenting with pitch detection and spectral estimators

See the question and discussion on StackOverflow: How to get the fundamental frequency using Harmonic Product Spectrum?.

We’re trying to estimate the fundamental frequency of a voiced A4 note (440 Hz). (See the question for link to audio clip.)

Harmonic product spectrum

Result: full data, 0 to 2 KHz
