AudioMundo is a reference site for the vocabulary of recorded sound. Audio is full of numbers that look interchangeable and are not: decibels, LUFS, kilobits per second, kilohertz, ohms. Each answers a different question, and spec sheets rarely stop to explain which one. The pages here take one term or one question at a time — what a decibel measures, what LUFS adds that dBFS misses, whether FLAC really loses nothing, what 44.1 kHz and 16-bit mean — and answer it in a few hundred words, with links to the standards bodies and government references that define the terms.
The site's working tool is the bitrate and file-size converter: enter a figure in kilobits per second, megabytes per hour, or gigabytes per hour, and read off the equivalents. It answers the most common practical question in this subject — how much space an hour of audio at a given bitrate actually occupies — without a spreadsheet.
Everything here is definitional and descriptive. Where a question turns personal — your hearing, your ears, your exposure — the pages point to the primary references at NIDCD and the WHO and to hearing professionals, not to a verdict from us.
