A waveform is a picture of loudness over time, and it is the standard visual shorthand for audio — on podcast artwork, episode pages, audiogram posts and player interfaces. Load a video or audio file, choose how the waveform is drawn, and export a still image as PNG or as scalable SVG.

What the shape actually tells you

Height is amplitude, so tall regions are loud and flat regions are quiet or silent. Speech shows as clusters of peaks separated by visible gaps at every breath and sentence break; music shows as a denser, more continuous block. That makes a waveform genuinely useful before you edit: long flat stretches are dead air worth cutting, a solid wall touching the top and bottom edges means the recording is clipped, and a waveform that barely rises off the centre line means the track was recorded far too quietly.

PNG or SVG

PNG is a fixed grid of pixels — right for social posts, thumbnails, episode art and anywhere the image is used at roughly the size you exported. SVG describes the shape as vectors, so it stays crisp at any size and can be recoloured or resized in CSS after the fact. Choose SVG when the waveform goes into a website, a print layout or a design file; choose PNG when it needs to be dropped straight into a post or a video frame.

Questions, answered

What does a waveform actually show?

Amplitude over time — how loud the audio is at each moment. It shows nothing about pitch or frequency content, which is what a spectrogram is for.

Should I export PNG or SVG?

PNG for social posts and thumbnails used at a fixed size. SVG for websites, print and design work, where it stays sharp at any scale and can be recoloured later.

Can I generate a waveform from a video file?

Yes. The soundtrack is decoded from the video and drawn, so you do not need to extract the audio first.

Is this an animated waveform for a video?

No — this produces a still image. For a moving waveform rendered as a video file, use the audio visualizer tool.

How can I tell if my recording is clipped?

Look for flat-topped regions where the waveform slams against the upper and lower limits and stays there. That is signal that exceeded the maximum and was cut off, and it cannot be undone after recording.
