Shared Claude Code translation pipeline (scripts/i18n, no API key) plus Astro/VitePress/Scalar i18n wiring. Landing and API reference translated into all 20 languages; docs i18n wiring + English source anchors. The translated docs markdown (apps/docs/<locale>/**, 3,620 files) follows in a companion PR because it exceeds GitHub's per-PR CI file limit.

|
## Notes {#notes}
|
|
|
|
- `stereo-to-mono` mixes both channels into a single mono track.
|
|
- `mono-to-stereo` duplicates the mono channel to both left and right.
|
|
- `swap` exchanges the left and right channels of a stereo file.
|
|
- Output usually keeps the input container. AAC input is written as M4A, and unsupported decode-only inputs fall back to MP3.
