The super talented [Switch Angel] is an electronic music artist, with a few cool YouTube videos to show off their absolute nailing of how to live code with Strudel. For us mere mortals, Strudel is a JavaScript port of TidalCycles, which is an algorithmic music generator which supports live coding, i.e. the music that is […]
Bose SoundTouch speakers were introduced in 2013, offering the ability to connect to online streaming services and play back audio on multiple speakers simultaneously using the accompanying mobile app. Now these features are about to be removed, including the mobile app, as Bose is set to discontinue support on February 18, 2026. From that point […]
It’s been a while since the last installment in our Know Audio series, in which we investigated distortion as it applies to Hi-Fi audio. Now it’s time to return with part two of our look at distortion, and attempt some real-world distortion measurements on the bench. Last time, we examined distortion from a theoretical perspective, as […]
S/PDIF has been around for a long time; it’s still a really great way to send streams of digital audio from device A to device B. [Nathan Ladwig] has got the ESP32 decoding SPDIF quite effectively, using an onboard peripheral outside its traditional remit. On the ESP32, the Remote Control Transceiver (RMT) peripheral was intended […]
When you think of a Bluetooth speaker, you’re probably picturing a roughly lunchbox-sized device that pumps out some decent volume for annoying fellow beachgoers, hikers, or public transport users. [Matt Frequencies] has developed something in an altogether different form factor—tiny Bluetooth speakers you can dangle from your earlobes! They’re called Earrays, and they’re awesome. The […]

[Shalma] begins by telling you a little about Joseph Fourier, the French mathematician with an interest in heat propagation who founded the field of harmonic analysis in the early 1800s. Fourier’s basic insight was that you can represent everything as a sum of […]
Over on his blog our hacker [Scott Baker] restores a Prompt 80, which was a development system for the 8-bit Intel 8080 CPU. [Scott] acquired this broken trainer on eBay and then set about restoring it. The trainer provides I/O for programming, probing, and debugging an attached CPU. The first problem discovered when opening the […]
To anyone who remembers Y2K, Sony’s MiniDisc format will probably always feel futuristic. That goes double for Sony’s MZ-RH1, the last MiniDisk recorder ever released, back in 2006. It’s barely larger than the diminutive disks, and its styling is impeccable. There’s a reason they’ve become highly collectible and sell for insane sums on e-Bay. Unfortunately, […]
Despite the regularly proclaimed death of physical media, new audio albums are still being published on CD and vinyl. There’s something particularly interesting about Lorde’s new album Virgin however — the CD is a completely clear disc. Unfortunately there have been many reports of folks struggling to get the unique disc to actually play, and […]
If your guitar needs more distortion, lower audio fidelity, or another musical effect, you can always shell out some money to get a dedicated piece of hardware. For a less conventional route, though, you could follow [Brek Martin]’s example and reprogram a handheld game console as a digital effects processor. [Brek] started with a Sony […]
