Sound made visible
A waveform is the visual shape of a sound over time, showing how loud it is moment to moment. This displays the waveform of an audio file in your browser, so you can see the shape of a sound, all processed locally so the file never leaves your device.

What a waveform shows
Seeing sound as a waveform reveals its structure at a glance: the height shows loudness, so you can see where a track is loud or quiet, spot the beats as regular peaks, find silences as flat sections, and see the overall dynamic shape of a piece. This is genuinely useful for navigating and understanding audio — locating a particular moment, seeing the structure of a song, identifying where sound starts and stops, or spotting problems like clipping, where the waveform hits its limit and flattens, indicating distortion. It is the standard view in audio editing, where the waveform is how you see what you are working with. While a waveform shows loudness over time, it does not directly show pitch or frequency content, which is what a spectrogram reveals instead. Doing this in the browser means even a private recording is visualised locally without uploading, so you can examine the shape of your audio on your own device. Seeing sound made visible turns an invisible signal into something you can read and navigate.
Questions & answers
What does a waveform show?
Loudness over time — the height shows how loud the sound is moment to moment, revealing beats as peaks, silences as flat sections, and the dynamic shape of a piece.
Does a waveform show pitch?
No — it shows loudness over time, not pitch or frequency content, which a spectrogram reveals instead.
Is my file uploaded?
No. The waveform is drawn in your browser, so the file stays on your device.
