24 alternatives to Decibel Meter
Hey 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…

This has been a pet project of mine for the past ~5 months. It consists of six visualizations: - Spectrogram: Implements the reassignment method for sharper time and frequency resolution. - Spectrum analyzer: A-weighted, frequency guidelines, loudest frequency tooltip. - Waveform: Colored based on frequency, loudness, or static - Oscilloscope: Tracks pitch and autocorrelates against a reference signal, provides stability. Also includes a regular zero-crossing trigger. - Stereometer & Phase meter: Linear and exponential scaling modes, adjustable windows. Multi-band correlation meter. -…

Hey HN, I build "How Loud Is My Hotel?" as a simple way to check for possible loud noise near a hotel (or any other address) before booking it. I've had some negative experiences in the past so this automatically checks for things like nearby Clubs, Police Stations with sirens, big roads, railroads etc. and gives you a "noise score" based on them. It's free, works worldwide and needs no account. It estimates outside noise risk rather than measuring decibels, so building insulation and temporary noise aren’t included.

Hi HN, I’ve been working on a browser-based tool for exploring and debugging Web Audio API graphs. Web Audio Studio lets you write real Web Audio API code, run it, and see the runtime graph it produces as an interactive visual representation. Instead of mentally tracking connect() calls, you can inspect the actual structure of the graph, follow signal flow, and tweak parameters while the audio is playing. It includes built-in visualizations for common node types — waveforms, filter responses, analyser time and frequency views, compressor transfer curves, waveshaper distortion, spatial…
