SnapOtterandGitHub 00b651c9f8 feat(i18n): 21-language pipeline, landing/docs/API wiring, landing+API translations

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.

Strip silent sections from an audio file.

Silence Removal

Detect and remove silent sections from an audio file based on a configurable threshold and minimum duration.

API Endpoint

POST /api/v1/tools/audio/silence-removal

Accepts multipart form data with an audio file and a JSON settings field.

Parameters

Parameter	Type	Required	Default	Description
thresholdDb	number	No	`-50`	Silence threshold in dB (-80 to -20). Audio below this level is considered silent.
minSilenceS	number	No	`0.5`	Minimum silence duration in seconds to remove (0.1 to 5)

Example Request

curl -X POST http://localhost:1349/api/v1/tools/audio/silence-removal \
  -H "Authorization: Bearer si_your-api-key" \
  -F "file=@audio.mp3" \
  -F 'settings={"thresholdDb": -45, "minSilenceS": 1}'

Example Response

{
  "jobId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
  "downloadUrl": "/api/v1/download/a1b2c3d4-e5f6-7890-abcd-ef1234567890/audio.mp3",
  "originalSize": 4500000,
  "processedSize": 3200000
}

Notes

A higher (less negative) threshold is more aggressive and removes quieter passages as well as true silence.
Increase minSilenceS to only strip longer pauses while keeping short natural gaps.
Useful for cleaning up podcast recordings, lectures, and voice memos.
Output usually keeps the input container. AAC input is written as M4A, and unsupported decode-only inputs fall back to MP3.
