See an audio file's waveform without a DAW
Drop a WAV, MP3, or OGG and get a waveform plot plus peak/RMS levels and duration — a quick loudness and clipping check.

The job
Before uploading a clip you want to know: does it clip? Is it silent for 30 seconds at the end? A waveform plot answers at a glance — peaks, RMS, and duration without opening an editor.
Drop the file
Open a WAV, MP3, OGG, or other browser-decodable audio file. The tool decodes it locally, draws the min/max envelope across all channels, and reports duration, peak level, and RMS level.
- Peak at or near 1.0 (0 dBFS) means the track is probably clipped.
- RMS is the perceptual loudness proxy — compare it against your target, not the peak.
Worked example
A voice memo shows a flat 20-second tail of silence and peaks at −6 dB — safe to upload, worth trimming.
Where it stops
Decode-and-plot only — no editing and no spectrogram; a PNG of the waveform can be downloaded. Files are limited to 10 minutes, 150 MB, and browser-supported codecs (Safari lacks OGG). Peak memory holds the decoded PCM, roughly 40 MB per minute of stereo. Nothing is uploaded.
