How To Install rnnoise on CentOS 8

rnnoise is Recurrent neural network for audio noise reduction

Introduction

In this tutorial we learn how to install rnnoise on CentOS 8.

What is rnnoise

RNNoise is a noise suppression library based on a recurrent neural network. While it is meant to be used as a library, a simple command-line tool is provided as an example. It operates on RAW 16-bit (machine endian) mono PCM files sampled at 48 kHz. It can be used as ./examples/rnnoise_demo The output is also a 16-bit raw PCM file.

We can use yum or dnf to install rnnoise on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install rnnoise.

Install rnnoise on CentOS 8 Using dnf

Update yum database with dnf using the following command.

sudo dnf makecache --refresh

The output should look something like this:
