DayBee

English | 中文

DayBee is a tray-first desktop recorder built with Go and mygo. It records microphone audio for long sessions, segments files automatically, and uses selectable sherpa-onnx ASR models plus Silero VAD for live transcription and offline reprocessing.

Features

• Long-running microphone recording with automatic segmentation
• Live transcription with lightweight Whisper Tiny/Base/Small, SenseVoice Small, Qwen3 ASR 0.6B or FireRedASR2 AED/CTC (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
• Native echo cancellation on macOS to reduce speaker playback in recordings and transcripts
• Optional macOS system audio capture, saved and displayed separately from microphone speech
• WAV and FLAC output
• Batch transcription of existing WAV/FLAC recordings
• Recording history viewer grouped by day
• Annotate transcripts with app names and icons from the same recording period; filter transcripts and recordings by app
• System tray app with launch-at-login, start-on-launch, and auto-update
• Bilingual UI (English / 中文)
• Light / Dark / System theme

Download

• Release page: DayBee Releases
• macOS 13.3+: Apple Silicon / Intel .dmg
• Windows: .exe (NSIS installer)

Runtime Notes

• New installations start with lightweight Whisper Tiny (INT8). Whisper Base/Small, SenseVoice Small (2025), Qwen3 ASR 0.6B and FireRedASR2 AED/CTC are also available in Transcribe settings. Existing model choices are preserved. The page shows download size, progress and installed status; models can be switched while recording, and queued speech finishes with its original model.
• Silero VAD downloads when recording starts. The selected ASR model downloads when chosen or when live/batch transcription first needs it. Existing model caches are reused; failed downloads preserve the previous selection.
• Native audio capture, sherpa-onnx 1.13.8 and ONNX Runtime 1.28.2 are bundled. Installed apps need no Node.js, Bun or Go runtime.
• WAV/FLAC encoding, decoding, downmixing and resampling run directly in Go. Existing FLAC recordings remain readable; no FFmpeg executable or system installation is required.
• On macOS, echo cancellation is enabled by default, including for existing settings. Turn it off in Input for unprocessed capture. Auto-switch input remains independently configurable and keeps echo cancellation enabled after switching; disconnect recovery remains available. See echo cancellation. System audio recording is opt-in on the same page; see source separation.
• Microphone app detection runs independently while DayBee is open, checks once per second, and requires macOS 14.2+ on Mac. Daily archives are stored under microphone-activity/ in the app data directory. See microphone activity notes.

Output

• Audio and transcript JSON files are archived under recordings/YYYYMMDD/
• Filenames look like daybee_YYYYMMDD_HHMMSS.wav or .flac
• With ASR enabled, each segment writes a matching .json with transcript text and metadata. ASR-disabled recording saves audio and capture timing metadata without transcript text.
