Eve Recorder (formerly eve, short for eavesdropper) is a tray-first desktop recorder built with Electron. It records microphone audio for long sessions, segments files automatically, and uses sherpa-onnx with Qwen3 ASR plus Silero VAD for live transcription and offline reprocessing.

• Long-running microphone recording with automatic segmentation
• Live transcription powered by Qwen3 ASR (can be disabled)
• VAD-only recording — only speech segments are saved to disk
• Real-time waveform visualization
• Manual microphone selection with automatic switch to the more active input
• WAV and FLAC output
• Batch transcription of existing WAV/FLAC recordings
• Recording history viewer grouped by day
• System tray app with launch-at-login, start-on-launch, and auto-update
• Bilingual UI (English / 中文)
• Light / Dark / System theme

• Release page: nexmoe/eve Releases
• macOS: .dmg or .zip
• Windows: .exe (NSIS installer)

The packaged app checks for updates automatically and installs them on quit.

• Eve Recorder downloads Qwen3 ASR and Silero VAD model files on first use and caches them under the app user-data directory.

• Audio and transcript JSON files are archived under recordings/YYYYMMDD/
• Filenames look like eve_YYYYMMDD_HHMMSS.wav or .flac
• Each segment writes a matching .json with transcript text and metadata
