I need to know how to use the high pass filter for audio that was recorded outside near a road and has low humming/hissing sounds. Im a newbie so what does rolloff rate, cutoff frequency and dry/wet mean?
How to set those to get rid of lower sounds underneath the talking?
thanks
You might also be interested in Noise Gate Audio Filter, but here is Audacity’s documentation for the high pass filter.
Wet = the signal with the filter applied. Dry = the signal without the filter.
