Silence Remover API

Long interviews and classroom captures ship faster when dead air disappears automatically. `/silence_process` ingests JSON with `video_url` plus `noise_threshold` parameters aligning with FFmpeg’s silence-detection idioms—energies below the threshold collapse after minimum gaps defined in docs. Outputs land in the ordinary async workflow: validate subscription keys, enqueue FFmpeg, poll task metadata, fetch trimmed media—all without multipart uploads bloating gateways. Archival librarians still annotate which passes were algorithmic versus hand-tuned metadata for FOIA responsiveness.

Threshold dialing is iterative: HVAC noise fights naive gates, while aggressive slicing can butcher comedic timing. Editors often preview locally using raw ffmpeg graphs, tune `noise_threshold` empirically, then lift those decimals into queued JSON batches that resume automatically when browsers close. Stitch `/cut` jobs ahead of silence detection when countdown leaders must disappear before metering speech energy.

Unlike consumer “jump cut bots,” this endpoint documents failure semantics when tracks lack audio entirely or when Dolby layouts confuse channel mapping. Logs cite channel indexes so engineers can remap before requeueing. Observability metrics quantify how many seconds each job removes so finance can compare storage savings versus manual editor hours. When speech overlaps room tone, raise thresholds slightly rather than chasing impossible zero-cross perfection.

Enterprise compliance still demands human review for legal depositions—auto trimming remains an editorial assistant rather than sworn testimony. Understand which retention tiers apply before betting on long-lived download mirrors; subscriptions define how aggressively cold storage rotates even when your JSON payloads stay identical.

Throughout, JSON plus HTTPS remains the contract: host files on durable TLS endpoints, never embed secrets in URLs, and throttle cron jobs with exponential backoff when queues show saturation signals. Finance podcasts adore `/silence_process` until deliberate dramatic pauses disappear—export A/B FFmpeg settings locally, annotate runbooks, then promote thresholds that preserve performer beats while shortening wall-clock listens. Remember silent B-roll cues still qualify as programmatic audio; annotate those chapters before automation runs.
