SnapOtter 8532f3227b docs: audit all 157 tool pages against live schemas

Reconcile every tool page's parameters, defaults, and response shape against the tool's Zod settings schema and executionHint in code. Notable fixes: color-palette (add count + format params, hex output, median-cut algorithm), favicon (add 5 params, was documented as having none), qr-generate (add logoDataUri), convert (add ppm/eps/tga formats), video-loudnorm (-16 LUFS not -14), smart-crop (async 202 not sync 200), images-to-video (1080x1080 square), and several output-filename and behavior-note corrections.

Also normalize API endpoint paths to /api/v1/tools/<id> (no modality segment) and standardize curl examples on the Docker API port 1349. Verified with a clean docs build.

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/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/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 format matches the input format.
