What it does
"Positive" adds an offset to raw dBFS. "Negative" shows the actual dBFS value (usually below 0). Applies standard frequency weighting using FFT analysis to better reflect perceived loudness (dBA) or low-frequency content (dBC). How often the display and graph update. Faster rates use slightly more CPU for UI rendering. How long the highest measured peak reading is displayed before potentially resetting. Adjusts the displayed reading (+/- dB) for relative comparison. Visual representation of the sound level or frequency content.

Decibel MeterNov 2025 · decibelmeter.org · ▲8Hey HN! I built a browser-based decibel meter that lets you measure sound levels without installing any apps or software. The tool uses your device's microphone to measure sound from 30-130 dB, with A-weighting to match human hearing perception. It works on both desktop and mobile browsers. Key features: - No installation required - runs entirely in the browser - A-weighted measurements (standard for noise exposure) - Educational content about sound levels and hearing protection - Reference guide for common sound levels - Privacy-focused: all processing is done locally, no audio is recorded…

Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
