The Browser-based Audio Analyser is a versatile audio analysis tool that runs entirely in a standard web browser using the Web Audio API, without requiring any software installation or external hardware. It provides real-time visualisation of key audio parameters, making it suitable for quick inspection, troubleshooting, and educational use.
The tool includes a time-domain oscilloscope for viewing waveform shape and dynamics, a frequency spectrum analyser for inspecting spectral content, and digital level meters for monitoring signal level and balance. A stereo phase / correlation display is provided to assess mono compatibility and channel phase relationships, while analog-style VU meters offer a familiar reference for average signal level.
Audio can be analysed from local audio files or live browser audio input, allowing users to perform fast checks without routing signals through dedicated analysis software. The analyser is intended for indicative measurement and visual feedback rather than formal compliance or calibration.
All processing is performed locally in the browser; no audio data is uploaded, stored, or transmitted. This makes the tool suitable for use in studios, classrooms, laboratories, or field environments where installing specialised audio analysis tools is impractical or unnecessary.
The Browser-based Audio Analyser is designed for basic audio verification, signal inspection, demonstrations, and teaching, complementing professional audio analysers and metering systems rather than replacing them.
