Introduction

In this tutorial we learn how to install rtfilter on Fedora 34.

What is `rtfilter`

rtfilter provides a library written in C implementing realtime digital filtering functions for multichannel signals (i.e. filtering multiple signals with the same filter). It implements FIR, IIR filters and downsampler for float and double data type (both for real and complex valued signal). Additional functions are also provided to design few usual filters One of the main differences from other libraries providing digital signal processing is that the filter functions have been specifically designed and optimized for multichannel signals (from few channels to several hundred). If data allows it, the library automatically switch to optimized SIMD (Single Instruction Multiple Data) code, allowing to reduce by 3~4 the time spent in processing the data. rtfilter 1.1 13.fc34 x86_64 31 k rtfilter-1.1-13.fc34.src.rpm fedora Realtime digital filtering functions for multichannel signals http GPLv3 and LGPLv3 rtfilter provides a library written in C implementing realtime digital filtering functions for multichannel signals (i.e. filtering multiple signals with the same filter).

We can use yum or dnf to install rtfilter on Fedora 34. In this tutorial we discuss both methods but you only need to choose one of method to install rtfilter.

Install rtfilter on Fedora 34 Using dnf

Update yum database with dnf using the following command.

sudo dnf makecache --refresh

The output should look something like this:

Fedora 34 - x86_64                               20 kB/s | 6.6 kB     00:00
Fedora 34 openh264 (From Cisco) - x86_64        1.4 kB/s | 989  B     00:00
Fedora Modular 34 - x86_64                       68 kB/s | 6.5 kB     00:00
Fedora 34 - x86_64 - Updates                    3.5 kB/s | 6.2 kB     00:01
Fedora Modular 34 - x86_64 - Updates             17 kB/s | 5.9 kB     00:00
Metadata cache created.

After updating yum database, We can install rtfilter using dnf by running the following command:

sudo dnf -y install rtfilter

Install rtfilter on Fedora 34 Using yum

Update yum database with yum using the following command.

sudo yum makecache --refresh

The output should look something like this:

Fedora 34 - x86_64                               20 kB/s | 6.6 kB     00:00
