Aki Waveform Studio

A waveform is a chart of a signal's amplitude over time, loud parts draw tall and quiet or silent parts draw low. It lets you spot a track's structure and catch issues like extra silence or clipping.

No. Just drag an audio file into the browser, the tool runs entirely on AkiApp with no install or login required.

Drag directly on the waveform to draw a selection, and the tool automatically loops playback inside that region. Click the clear button when you no longer need it.

No. Reading and rendering the waveform happens entirely in your browser, the file is never uploaded anywhere.

Yes. The tool ships with a few ready-made color themes, each pairing a wave color, a playback progress color, and a cursor color, applied instantly with a single click.

Bars draw the waveform as separate vertical strokes, with adjustable width, gap, and corner radius. A continuous line draws one smooth, unbroken wave shape, similar to a traditional waveform.

Normalize stretches the signal's amplitude to fill the display, so a quiet recording still renders a clear waveform instead of a flat, barely visible line.

For stereo files, it shows the left and right channel waveforms stacked separately, useful for visually comparing the two channels instead of viewing one merged waveform.
