I think I'm a code-jay
I like sitting at home jamming away, spending time tweaking things, able to think straight.
From-scratch is great and I'll always attempt that on occasion, but I'm happy to regurgitate code from recent sessions and not really write much on stage.
I love performance, but for now there is still too much adrenaline to be able to function clearly and keep track of what I'm doing.
Maybe these two things will meet in the middle and also I've very much against the idea of 'polished' code.

For me this is analogous to how I would write music for guitar and play it back. Or program an Akai MPC and mix the loops live with dubsiren.
I guess that would be live-arranging?

Interestingly I made Syntə with the intention of it being a 'live only' platform, I love the idea of that. I just find it hard to do code when I'm excited or with various levels of exhaustion.

My primary reason for favouring #Oppenheim's classic "Digital Signal Processing" #DSP textbook over all others—and, believe me, there are tonnes of good ones out there—is its eloquence, precision, concision, and comprehensiveness. It is, by no means, an easy read, but it (specifically, the "Orange Book", the 1ed from 1975) was the first book I read on the subject, and I still adore it, after all these decades.

This edition goes for less than $20 on eBay. Get it!

LG has made a thing called "Smart Diagnosis". On some devices you press a special button for a specific time and the device starts to emit a sequence of tones that sound a bit like a fax machine.

I am looking for
1) people with LG devices who are willing to record the sound and share it with me for further analysis
2) folks with a better understanding of digital signal processing who are interested to help out doing demodulation+decoding.

🧵 A little thread...

Some good #books on #DSP for #engineering undergrads:

for #EEs

• Digital Signal Processing, Oppenheim—the Bible
• Understanding Digital Signal Processing, Lyons—accessible, comprehensive, and practical
• Introduction to Digital Signal Processing, Kuc—dated but good
• Digital Filters, Hamming—a classic
• Wavelets and Filter Banks, Strang—straight from the Master
• Digital Signal Processing using ARM Cortex-M Microcontrollers, Ünsalan—STM32F4 bare-metal C programming using CMSIS-DSP library

for non-EEs

• The World According to Wavelets, Hubbard—easy overview by a non-STEM writer who interviewed all the big names in wavelet research
• The Scientist and Engineer's Guide to Digital Signal Processing, Smith—the gentlest

Bottom line: the more broadly read the student is, the more accessible the subject becomes.

Четыре колонки вместо шести. Домашний кинотеатр 5.1 в маленькой комнате

Вводные данные такие: Небольшая комната 22 м2. Прямоугольной формы. По длинной стороне телевизор 55 дюймов. Над ним проектор, направленный на противоположенную сторону, на которой ослепительно белые обои, это экран. Источник видео – ТВ бокс на Android TV. Источник звука - две пары недорогих напольников Premiera ES-621 MC. Задача – сделать домашний кинотеатр с объемным звуком 5.1 высокого качества с небольшими затратами. Вносить в комнату сабвуфер и центральный канал нельзя. Не разрешили, да и некуда. Поэтому делать кинотеатр нужно на четырех колонках расставленных по углам комнаты. Квадро, но со звуком 5.1 Делаем так: Cinema Q . Четырехканальный USB аудио ЦАП

Btw. Here's another 6½min live performance from my talk @ #Resonate 2016. Alas, there were some cable issues on stage and I had to record it all afterwards in my hotel room. The setup was the same as in the first video from the previous post (i.e. STM32F746 DISCO + Korg Nanokontrol)

Just realised the readme for thi.ng/synstack (a C11 & Forth-based softsynth engine for #STM32) had broken links to two live performances/demos I creeated in early 2016. I've now fixed those and re-uploaded these videos to my Makertube/Peertube:

Okay #math and #dsp folks. Is there a noise function that I can initialize to generate a mode between to values?

Say I have a function f(x) which generates either 1 or 0 each time I call it. I call it N times, and sum the ones and zeros and then divide by N, I want the result to be "P" (which is a number 0 <= P <= 1)

A uniform distribution gets me 0.5, I want a distribution that centers around P.

Thoughts? Plan of attack? References?

Formula showing the average value from a noise function returning 1 or 0.

One way to get more variety when transforming data into audio is to change the encoding. Today I'm implementing the VOX ADPCM telephone codec — which I especially like — in Rust to accomplish this! reillyspitzfaden.com/posts/2025/0... #DSP #Audio #Rust #Programming #Coding #ElectronicMusic

Also, where do people go to ask random annoying DSP questions in 2025? I feel like I know where to find programming/software ponderings, but I usually just get some vague and sometimes uninformed info when I search for DSP. Are there forums? A Discord? Is stackexchange still relevant?
