If you are looking to isolate audible speech try combining a lowpass filter with a high pass filter. For usable audio I have noticed that filtering out 200hz and below then filter out 3000hz and above does a pretty good job of keeping usable voice audio. ffmpeg -i <input_file> -af "highpass=f=200, lowpass=f=3000" <output_file>

The stopband of a low-pass or high-pass filter is the region of the spectrum (the frequency range) over which the filter is intended not to transmit its input. The stopband attenuation is the difference, in decibels, between the lowest gain in the passband and the highest gain in the stopband. Ideally this would be infinite; the higher the better.A low pass filter is called “low pass” because it lets only the low frequency components of a signal to pass through and blocks the high frequency components (like noise)..

Low-Pass Filters have low output impedance; thus, it prevents the filters cut-off frequency from being affected because of the load. ad. When you’re changing your vehicle’s oil, not only do you want to replace the old oil, but replace the oil filter itself. The oil filter plays an important role in keeping dust, dir... The above discussion considered a low-pass filter, but a high-pass filter can be composed by inverting the sign of the kernel of the low-pass filter, and adding one to its center (Smith, 2003, Chap. 14 & 16). This has the effect of flipping the step function of the low-pass filter in the frequency domain, so that it becomes a high-pass filter.
