# audioeditor.org

> A free, browser-based audio editor and a suite of ~40 single-purpose audio tools. All processing runs locally in the browser using the Web Audio API, WebAssembly (FFmpeg.wasm), and Mediabunny — audio files never leave the user's device. No signup, no upload, no cost.

audioeditor.org is built with Nuxt 3 and Vue 3, and is fully internationalized across 10 locales (en, zh-hans, zh-hant, ja, ko, ru, de, fr, es, pt-BR). English is the default and is served at the root path; every other locale is served under a `/<locale>/` prefix (e.g. `/zh-hans/tools/trimmer`). The site uses the `prefix_except_default` i18n strategy.

The codebase is a pnpm monorepo. Reusable audio processing lives in workspace packages under `packages/`: `@audiotools/core` (decode/encode/trim/merge/resample via Mediabunny), `@audiotools/effects` (DSP processors), and per-tool packages for trimmer, merger, converter, splitter, vocal-remover, recorder, visualizer, and video-to-mp3. Each tool page is an independent Vue page under `pages/tools/` with its own module, making the tools unit-testable in isolation. Wavesurfer.js powers waveform visualization.

Privacy is a core feature: because every tool processes audio in-browser, no file is ever uploaded to a server. The site is free with no account required. The full multi-track editor at `/editor` is currently under construction and redirects visitors to the tools directory.
