(edit next two paragraphs)

septabee is a free daw recently released put up for public early access. it's basically plugdata on steroids. the dev claims to have been working on it for 20000 hours, with the current version having been started on January of this year. apparently she made a whole programming language for it

the daw is special bc there's individual dsp modules that let you do all sorts of crazy stuff. watch the video. and it's even more special because it apparently "codes itself" in real time to find the best way for what it's doing to be as fast as possible on any cpu. i believe this is what the programming language they made (b++) is for, the dev claims it's faster than c++ because of the live cpu optimization thing. again, watch the video

John Tukey the Fast Fourier Transform (FFT) inventor, who coined both "bit" and "software" died exactly 26 years ago today.

The Fast Fourier Transform (FFT), one of the most important algorithms in signal processing and data analysis, was introduced by Tukey & Cooley in 1965.

In 1805, Gauss - studying the orbits of asteroids Pallas and Juno - came up with a method to interpolate their trajectories from discrete samples. What he came up with was mathematically very close to the modern FFT but Gauss never published that work, and didn’t analyze its computational complexity. It predated even Fourier’s 1822 work on heat diffusion - but without the framing or generalization that Cooley & Tukey would bring 160 years later.

In 1965, Cooley & Tukey published their now-famous algorithm that reduced the cost of computing a Discrete Fourier Transform from 𝑂(𝑛²) to 𝑂(𝑛 log⁡𝑛). This leap made real-time signal processing and digital media compression feasible.

From radio telescopes to JPEGs, from audio codecs to quantum mechanics - the FFT is everywhere. It’s one of the most important (and elegant) algorithms of the 20th century - rooted in the genius of Gauss, but brought to life in the computer age.

You know the agingtv GStreamer element, the one that makes the colours of a picture duller and adds noise so that it looks like it's coming from an old TV?

I wrote agingradio during the hackfest - instead of ruining your video, it ruins your audio! 🎉 Imagine listening to music on a very old radio, or calling a customer service hotline and suffering through the hold music whose quality is insufferable.

It supports five different types of distortion:

1) White noise (of configurable amplitude)
2) Clicks (of configurable probability)
3) Low-pass filter (of configurable frequency)
4) Quantisation noise (of a configurable amount of bits)
5) Cubic curve distortion / odd harmonics (of configurable amount and # of passes)

It is part of rsaudiofx and merged as of a couple of hours ago: https://gitlab.freedesktop.org/gstreamer/gst-plugins-rs/-/merge_requests/3087

I used the Chilli hold music from https://github.com/Hypfer/HotlineValetudo/tree/master/HotlineValetudo/Audio/holdmusic as a test case (Chilli.mp3 by @janhenrik , CC-BY-NC-SA). The result, using the element's default values, is attached to this post.

Given everything that we can do with noise-cancelling headphones and signal processing, why are they not able to cancel out the whine of the drones when doing follow-cam in sporting events? 🧐

Ever wondered how to render a smooth, audio-reactive waveform using Canvas? We're peeling back the layers of our latest project in building Ramble. Perfect for #AudioProcessing enthusiasts and #WebDev pros alike! https://www.doist.dev/building-ramble-3-visualizing-the-waveform/

Bitwave is a new open-source audio format built with Rust & Python. It embeds spatial data & BPM for immersive, adaptive experiences in VR and gaming. https://hackernoon.com/its-time-to-reinvent-the-audio-file-introducing-bitwave #audioprocessing

A #webdev project is getting to a good place, starting to think about the next thing. Thinking about building some hardware for realtime audio processing with a #RaspberryPi #ComputeModule and a custom audio interface with an #RP2040

I want to do some mixing and EQ of multiple audio sources in a small package I can embed into other things. Diving into the #USB spec is a daunting task but seems like the most compatible way to send samples fast.

Neural audio codecs: how to get audio into LLMs

Decided to have another go. #PlugData is considerably less intuitive at this point than the #BitwigStudio Grid environment, but appears to be very light weight. Here we have a patch that is coming together where we have a continuous output that blends between Low Pass, Band Pass and High Pass. #VisualProgramming #SignalProcessing #AudioProcessing
