Read RMS and peaks as signal measurements

Audio Level Rack measures a supported WAV excerpt locally. Whole-excerpt RMS includes silence; sample peak is the largest absolute sample across the channels.

Open the local tool

Use the supported source

This version accepts mono or stereo PCM 16-bit or IEEE float 32-bit WAV, up to 120 seconds and 25 MB. Compressed/extensible WAV and MP3 are outside its parser. The file and original signal are not changed.

Keep each number with its method

RMS is the square root of mean squared amplitude; dBFS uses 20 times log10 of that amplitude with 1 as full scale. Stereo energy is averaged without a downmix. Crest factor is peak dBFS minus RMS dBFS. Digital silence has no finite dBFS level. Full-scale sample counts alone do not prove audible clipping.

Compare without pretending to process audio

  1. Choose an adjustable RMS working reference appropriate to your comparison.
  2. Read the sample-peak ceiling alongside the proposed linear gain.
  3. Use a proper loudness measurement method when a publishing requirement names LUFS or true peak.

Keep the limit in view

No perceptual gating, K-weighting, LUFS, true-peak oversampling or playback calibration is performed. The gain scenario creates no processed file and does not protect against inter-sample peaks or codec overshoot.
