Provide either url (HTTP/HTTPS) or ref (id from a prior tool call). strength is 1–100 (higher removes more but risks a hollow sound; start around 12). method is afftdn (FFT, default) or anlmdn (non-local means). Set remove_hum to also cut low-frequency hum below 80 Hz. The output keeps the input container. Note: runs on the standalone page and the CLI (chat ffmpeg is unavailable).",
