Raspberry Pi Zero 2 powered smart display with two modes: a MagicMirror² and a real-time audio spectrum analyzer & decibel meter. Modes are switched remotely via MQTT, with native Home Assistant integration. Designed for a 14" matte LCD to mimic an e-ink aesthetic.

Custom Lab Monitoring: Create and track sensor labs. Speed Meter: Enhanced GPS tracking. Pedometer: Steps, calories, and activity stats. Noise Meter: Custom presets with icons. Ads: Shown at key moments. Performance: Faster, lighter, more stable. UI/UX: Improved visuals and error handling.

modern real-time decibel monitoring web application that measures microphone input and displays live sound levels with an intuitive UI. The app features real-time dB tracking, customizable noise threshold alerts, and microphone device selection — designed for classrooms, workplaces, streaming setups, and noise monitoring environments.

Free, private online sound level meter — measure noise in decibels (dBA, LAeq, A/C/Z) right in your browser. 8 languages, keyboard-first, no app.

Read live readings and download the onboard recorded logs from a Benetech GM1356 USB sound level meter (macOS/Linux, pure Python) — incl. the previously-undocumented record-import protocol

A professional-grade sound level meter built with Flutter. Features real-time dB monitoring, acoustic weighting filters (A, C, Z / Fast, Slow, Impulse), multi-view charting (waveform, FFT spectrum), and audio recording with persistent offline history.
