Each widget runs the same calculation as the full tool on this site, stripped back to the part worth putting on someone else's page. Copy the iframe, paste into a post, and the widget loads with no script tags and no tracking.
Embedding suits a page where the reader needs one number and would lose their place by leaving. A post about podcast loudness benefits from a loudness target sitting inline. A post surveying six topics does better with a link.
Height is fixed by the attribute in each snippet. The widgets stay responsive down to phone width, so leave width at 100 percent and adjust height alone if your layout needs a change.
Each widget carries an attribution link back to the full tool. Leave the link in place and you are free to use these on commercial sites, course pages and internal wikis. No account, no key, no permission request.
How to choose which widget to embed
Pick the widget answering the question your page raises rather than the one covering the most ground. A post about loudness targets benefits from a loudness widget inline, and gains nothing from a general calculator a reader has to configure before it says anything useful.
Place it where the question appears, not at the end. A reader reaching a paragraph that raises a number wants the number there, and a widget below the conclusion is one most people scroll past. Embedding is worth doing precisely because it removes a trip elsewhere, so putting it after the moment of need discards the benefit.
