What is "Cutoff Frequency"?
https://www.sweetwater.com/insync/cutoff-frequency/
Cutoff Frequency. Share this page: By Sweetwater on Jun 4, 1997, 12:00 AM. In a filter, the cutoff frequency is the point where the response is 3 dB down in amplitude from the level of the passband. Beyond the cutoff frequency, the filter will attenuate all other frequencies, depending on the design of the filter. On a sweepable shelving EQ or filter, what you are …
How do I identify CUTOFF frequency from my audio signal ...

If you have : FFT Size : 256 and Sample rate is 8000hz (the max frequency would contain on your data is 4000hz). then you have 8000/ 256 bin -> about 31.25 hz/ bin. the High Pass Filter: That means you want to get all data above f0 (= 2000 hz. Example) and remove all data below f0 (2000hz). Bin at 2000hz = 2000/ 31.25 = 64 bins.

Cutoff Frequency The cutoff frequency is defined as the frequency at which the ratio of the input output has a magnitude of 0.707. This magnitude, when converted to decibels using Eq. 1 is equal to –3dB, often referred to as the 3dB down point. = input output Magnitude 20log 10 (1) The cutoff frequency is characteristic of filtering devices, such as RC circuits.

In the audio world a filter does a very similar job. A cutoff filter is a processor, which can attenuate or completely remove certain partials out of any given frequency spectrum, when the signal is passed through it. The user sets the upper and/or lower frequency limit. Important terms to know Pass Band
How to cut out low frequencies from an audio file signal?

I am trying to cut out the huge spike at the beginning so that the PKS values come from the more meaningful data around the 0.5 area rather than the random low frequency noise from the recording closer to 0.

By setting the resistor and capacitor’s value and the preferred cut-off frequency, it’s possible to design a high-pass filter. In the above circuit, the cut-off frequency is about 160 Hz. A high-pass filter will pass all the frequencies higher than 160 …
