Editorial Policy
How content on Reverb Calculator is written, checked and corrected — the standards every page here is held to before and after it ships.
How content is written and checked
Every formula used on this site is derived from published sources — standard tempo arithmetic for the timing tools, and the Sabine and Eyring formulas with published absorption coefficients for the acoustic tool. The sources behind each claim are named on the page that makes the claim, and the full derivations live on the Methodology page, where any reader can reproduce them.
Numbers are not typed into pages by hand. Every calculator and table on the site is computed by the same shared calculation library, so a value shown on the home page, a tool page and the BPM to MS Chart is the same value, produced the same way. Before a page ships, its worked examples are recomputed independently by hand and compared against the library output, including at edge-case tempos.
Corrections policy
Errors get fixed openly. When a reader reports a wrong number or formula — through the Report an Error page — the claim is checked against the Methodology formulas. If the report is right, the page is corrected, and the fix is not hidden: significant corrections are acknowledged rather than quietly swapped in as if the error had never existed.
We would rather publish a correction than defend a mistake. A calculator site lives or dies on whether its numbers can be trusted, and a visible correction is evidence for that trust, not against it.
No sponsored placements or paid rankings
Nothing on this site is published because someone paid for it to be there. There are no sponsored articles, no paid placements, no affiliate-driven rankings and no guest posts. Tools are included because they belong to the reverb and delay family and can be built honestly, and sources are cited because they are the actual sources used — not because of any commercial relationship.
If that ever changes for any page, the commercial relationship will be disclosed on that page, in plain sight, before the content it affects.
AI assistance, disclosed
AI tools assist with drafting and code on this site, and we say so rather than hide it. The boundary is strict: drafting help is allowed, number generation is not trusted. Every formula, preset and published value is checked by a human against the published sources before it ships, and the worked examples exist precisely so readers can perform the same check themselves.
Accountability stays with the named maintainer. If a page is wrong, the responsibility is human, and so is the correction — see the About page for more on who maintains the site.
Update practice
Pages are reviewed when their sources change — when a referenced publication is revised, a standard is updated, or a better source replaces an older one — and whenever a credible reader report raises a question about a value. Reviews check the formulas first, then the worked examples, then the surrounding explanation, in that order.
Routine maintenance, such as clearer wording or a new preset, follows the same checking path as new content. No number changes on this site without being re-derived, whatever prompted the change.
Frequently asked questions
Where do the formulas on this site come from?
From published sources: standard tempo arithmetic for timing, and the Sabine and Eyring formulas plus published absorption data for acoustics. Sources are named on each page, with full derivations on the Methodology page.
What happens when a reader finds an error?
The claim is re-derived against the Methodology formulas. If the reader is right, the page is fixed and significant corrections are acknowledged openly rather than silently edited away.
Does any content here exist because of a sponsor?
No. The site carries no sponsored content, paid placements, affiliate rankings or guest posts. Tools and sources appear because the work calls for them, never because anyone paid for placement.
How is AI used in producing this site?
AI tools help with drafting text and code only. Every formula and number is human-checked against the published sources before shipping, and the named maintainer remains accountable for every page.
How often are pages reviewed?
Whenever a source changes, a standard updates, or a credible report questions a value. Reviews re-derive the formulas and worked examples first, then check the explanation around them.
