This is a fascinating space where logarithmic numbers can offer a lot of value with fewer bits.

Currently FPGAs are out of scope. But, would love to implement that use case as well in future.

I’m building SPARK (Signal Processing Algorithms, Routines, and Kernels), an open-source library of modular, efficient DSP components for low-power embedded audio systems. The goal is to make it straightforward to design and deploy small, c

Thank you! I will add them later on. You can access the schematic and PCBs here: GitHub: https://github.com/Colahall/tiny85fancontrol/tree/main/schem... Codeberg: https://codeberg.org/Col

I did try the internal temperature sensor, but it didn't measure the ambient temperature. I have read that if you set the ATtiny85 to sleep mode for some time, it will converge to ambient temperature, but it would take too long to vali

This project is great! I have used this API for a personal WiFi enabled dashboard on an ESP32.

It’s not a startup. It’s a studio. A workshop. A chain of curiosity. We build slowly, deliberately, until it’s awesome. No pitches. No pivots. Just noise…

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 actually works.

I have also documented how to vectorize IIR filters (EQ) in this article as well https://shafq.at/vectorizing-iir-filters.html

I thought I had mastered C: its 32 keywords, the many meanings of static, and even the arcane art of three-star programming. But C always has much more to explore. Let's dive into one of the strange corners of The C Programming Languag

If I recall correctly, SVFs typically compute lowpass, highpass, and bandpass outputs simultaneously, which are then combined to create peaking or shelving filters. In contrast, a traditional biquad filter requires only five multiply-accumu

Thank you for your feedback. You’re absolutely right that TDF-2 can exhibit artifacts in the presence of modulation or automation. In this implementation, I’ve addressed this by crossfading between the old and new coefficient sets. I’m awar

Thank you for taking the time to share such detailed feedback. It’s incredibly valuable! Let me address your points one by one: 1. Logarithmic plot and spectrum analyzer: This feature is definitely on my roadmap. I agree that having these v
