About Me

D'Angelo graduated with a first-class MEng in Computer Science and Electronics from the University of Bristol in 2025, and now works as a test engineer at Solid State Logic, applying that academic grounding to professional audio gear.

D'Angelo got their start in audio technology when their Guitar Hero controller broke, and they tried to repair it. That led to repairing more gear, then to realising they could design and build it themselves. That interest slowly turned into a passion as breadboard circuits and Visual Basic tutorials became small-signal circuit analysis and DSP lectures. Now, as a fresh face in an experienced industry, they're keen to learn everything they can and pass it on as they go.

    Real-time audio processing has a problem that hides in plain sight. It shows up when we want it the least, in the effects that we want the most. It starts with one tool we reach for all the time: The Discrete Fourier Transform is fundamental in digital signal processing. But in order to get the most out of it, it needs a long window of signal; that's a luxury rarely given in real-time audio. With only a small chunk of the whole signal, the next logical choice is to use the Short-Time Fourier Transform. There's always a catch, though, and […]
