Waveform Viewer
Peaks canvas + zoom + dB scale.
How to use
Drop audio into Waveform Viewer: choose the files below, press Run, and AudioForge processes everything with a Web Audio decode pipeline on your device — progress bar and cancel included. You get an instant result plus one-click download; originals are never uploaded, so DevTools Network stays clean.
Steps
- Open the tool below (or scroll to the interactive Waveform Viewer).
- Choose the files below audio.
- Press Run (Ctrl+Enter) and watch the progress bar.
- Download the result, or copy and share the link.
FAQ
Is Waveform Viewer really free?
Yes — free with no signup, no credits and no limits on this tool. It is supported by clearly labeled ads placed away from the buttons, never by paywalls.
Do I have to upload my files to use Waveform Viewer?
No. Your files are read with the File API and processed with a Web Audio decode pipeline on your own device — there is no upload endpoint at all. Open DevTools, go to Network, and watch: your file never leaves the tab.
Which files work with Waveform Viewer?
Waveform Viewer accepts audio up to 200MB. Anything bigger gets a clear message before any memory is allocated — never a silent hang.
I normally use 123apps — why switch?
If you are tired of upload queues for a 30-second trim and free exports with limits, AudioForge is the alternative: on-device Web Audio decode with real waveforms and WAV/Opus export, progress and cancel.
How accurate is Waveform Viewer?
Everything runs on your device, so results are instant and repeatable — same inputs, same outputs, no server involved.
