Peak is the single loudest sample (0 dB = maximum before digital clipping). RMS is a rough measure of average perceived loudness across the whole file — it's not a full standardized loudness (LUFS) measurement, but it's a useful quick gut-check. Processing happens entirely in your browser.

Frequently asked questions
What's the difference between peak and RMS?+
Peak is the single loudest sample in the file; RMS averages the signal's energy across the whole file, which correlates better with perceived loudness.
