Frequently asked questions
What are the output dimensions?
1200 by 200 pixels, a 6:1 strip. That shape sits above a player or inside a podcast episode card without pushing the rest of the page down.
Is it the real waveform or a decoration?
It is drawn from the decoded audio samples, so peaks and quiet passages line up with what you hear. It is not a random pattern.
Does it have a transparent background?
No, the PNG ships with a solid background. If you need it to sit over artwork, drop the background out afterwards in any image editor.
Can I use it for an audiogram?
Yes, that is the common use. Export the strip here, then composite it over your artwork in a video editor and let the playhead move across it.
