Can this python code remove real time reverb? #45

Closed torbjoif closed 3 years ago

torbjoif commented 4 years ago

Hey!

I have a wet sound of a clap inside a small room 4.3 x 1.8 x 2.4 meters. I want to remove the reverb from the sound before passing it on.

Later on I want to use this code to remove reverb from a machine room on a ship with several electric motors, hydraulics and valves. Is it possible to remove reverb with this code?

Hey, what do you mean with real time reverb? Do you search for an online dereverberation algorithm that can work on a device? If an algorithm works in real time always depend on the hardware and the code optimizations. Furthermore, many people have latency constraints, when they implement an algorithm.

I ment realtime as in live (with some latency of course). I was wondering about the algorythm and its computational cost.

In our paper "NARA-WPE: A Python package for weighted prediction error dereverberation in Numpy and Tensorflow for online and offline processing" in section 7.1 we wrote a section about the real time capacity of this code.
