｢ #GNURadio is a free & #opensource software development toolkit that provides signal processing blocks to implement software radios. It can be used with readily-available low-cost external RF hardware to create software-defined radios, or without hardware in a simulation-like environment. It is widely used in research, industry, academia, government, and hobbyist environments to support both wireless communications research and real-world radio systems ｣

Guess what, @7nihilate just released this whole-ass #Rust #DSP that's meant for cleaning voice audio. Its specialty is making your voice recordings clear enough that they can sound good even if you highly compress them... but it's also a step to making better and more free hearing aid tech.

There's a GUI here:

Last night, took a random sample from a discord I'm on and ran it through my DSP project to see what it would sound like.

Opened the resulting wav in RX9 and saw the wav looked mad; huge DC offset in the samples 🤔

Turns out the original sample had a small DC offset (0.03%) and time stretch + grains amplified it to 17%!

So, anyway, I've now got some DC offset filtering code aka a simple first order high pass to take out super low frequencies (sub-20hz or so) - problem solved👍

Crowdsourcing #DSP creativity!

You could help @gnuradio 's block documentation wiki a lot if you could try out our instructions for how to add example flowgraphs to Block Doc pages!
https://wiki.gnuradio.org/index.php?title=How_to_Add_an_Example_Flowgraph_to_a_Block_Doc

The documentation team (and countless contributors) have created a host of 555 block documentation pages to date. Not every single one of these has an example flowgraph that really illustrates the useful things you could do with that block.
Could you help?

Hey audio devs! We're looking for a Convolution Reverb and a De-Esser effect to add to Audacity! Anyone have any recs, or better yet, made one themself?

Boosts appreciated!

If you've ever wrestled with fixed-point math, scaling, and rounding, this blog post is for you!

I go deeper into binary arithmetic, division tricks, rounding, and what it really takes to build fixed-point systems that work.

As always, I appreciate all of your feedback and corrections.
