See any sound as a live frequency spectrum.

Runs entirely in your browser. Load an audio file or open your microphone and watch the frequencies move in real time — great for checking mixes, voices, and the shape of a sound. Nothing is uploaded.

MP3, WAV, OGG, M4A — up to 25 MB. We'll chart its frequencies live as it plays.

How it works

Your audio never leaves your device

The analyzer uses your browser's Web Audio API to decode the audio (or tap your microphone), run a real-time frequency analysis, and paint the spectrum — all on your machine, no server round trip.

Step 1

Choose a source

Upload an MP3, WAV, OGG or M4A — up to 25 MB — or use your mic.

Step 2

Press play

We analyse the signal frame by frame as it plays, in your browser.

Step 3

Read the spectrum

Bars rise with energy: bass on the left, treble on the right.
