Design reverb filter

Started by RoBoTBiLL 9 months ago3 replieslatest reply 9 months ago116 views


I want to create a filter for reverb effect third degree.

In order to create a filter for echo-effect I used this equation:


I also know that to create the reverb filter I will use echo filter in series.

What form will the equation for the reverb filter take?

Thanks in advance

I'm not an expert in reverberation but this might help you out:

I'm also not an expoert on reverb but I do know they are usually implemented by cascading all-pass filters.

Or skip to the Stanford section on Freeverb Here. What you have there is a slap back delay, which isn’t really a reverb. You could use feedback instead of feed forward, which will give a more proper echo.  You can also apply low pass filters to the feed back loop, which will help naturalize the response a bit (8 of which are used in Freeverb). The cascaded all pass filters are used to provide diffusion. The model is basically split into diffusion and early reflections. An alternative approach is to use pre rendered impulse responses and convolution. This is more computationally expensive and doesn’t provide a lot of room for control, but is more accurate
