Scanner DVR

DVR recording, live transcription, and export for online radio scanner feeds

Scanner DVR 2.0 turns your browser into a powerful monitoring tool for live radio scanner feeds. It automatically records audio into a rolling 30-minute buffer, so you never miss a transmission — even if you stepped away. Key Features: - DVR Recording — Every transmission is captured and available for instant replay. Click any past transmission to hear it again without interrupting the live feed. - Live Transcription — Real-time speech-to-text converts radio traffic into readable text using Deepgram's Nova-3 AI model. Requires a free Deepgram API key (includes $200 in free credits). - Save All Export — One click exports all captured audio clips and transcripts as an organized ZIP file. Each feed gets its own folder with timestamped audio files and a matching transcript.txt. - Dashboard Support — Monitor multiple feeds simultaneously. Each feed gets its own independent DVR panel with individual volume, mute, and stereo panning controls. - Audio Controls — Adjustable playback speed (0.5x-2x), per-feed volume, mute/unmute, stereo panning (left/both/right), and a master volume for dashboards. - Silence Detection — Automatically segments continuous audio into individual transmissions based on gaps in radio traffic. Adjustable silence threshold from 0.5s to 5s. Built for volunteers and monitors who need to document incidents, review past transmissions, and share recordings with their team. No data is collected or sent anywhere. Transcription requests go directly to your own Deepgram API key. All audio stays in your browser.
