How audio becomes numbers
FFT, frequency bins, bands, amplitude and onset: the measurements every visualizer reads.
Editorial
Last updated 2026-08-09. Publisher: Novus Stream Solutions.
How Sonic Weaver guidance is reviewed, sourced, corrected and updated, by the one person who builds it at Novus Stream Solutions.
Sonic Weaver is made by one person, the owner of Novus Stream Solutions in London, Ontario, who writes and maintains its product guidance by checking claims against the current browser implementation, the live engine catalogue, reproducible local tests, primary Web Audio and Canvas documentation, and the dated product changelog. The byline identifies who is responsible; it does not invent a named expert or professional credential.
Product and workflow claims are checked against the current application, catalogues, tests, and representative browser-local output before publication.
Readers can report a specific statement, route, source, or reproducible result that appears wrong or stale.
AI may assist outlining, code review, test generation, or draft editing, but it is not treated as a source or an accountable author.
Technical, platform, standards, and API claims prefer the organization that owns the specification or implementation.
Published and updated dates describe real editorial events and are shared by the visible article, metadata, schema, sitemap, and RSS feed.
Product-technical articles remain self-canonical on this domain. The explainer cluster uses two existing pillars (the glossary and the engine reference) rather than inventing a third hub. Other Novus Stream Solutions sites may summarize these articles; they must not republish the full text under a competing canonical URL.
