WebNov 2, 2024 · High-Pass Filter. On the other hand, a high-pass (or low-cut) filter will remove frequencies below a given threshold. For many producers, this has become a go-to step to give clarity to the mix. Low-cutting most elements except your kick and sub-bass between 60 Hz and 120 Hz will help tighten up the low-end. WebThe purpose of this demo is to illustrate through audio programming, how an adaptive filter can remove the sender's own echo from what he hears.

WebMar 2, 2024 · 1. Since you're adding white noise, the highpass and lowpass filtering will almost not remove the noise in the frequency band where you want to keep your signal, so you will always have some background noise with this highpass and lowpass filtering strategy. Not sure if this helps, it depends on the signal-to-noise ratio: If you can clearly ...
