What is the best meeting recording software for PC on Windows 11?

The VoiceFlow is the open-source, local meeting recorder for Windows developed by infiniV on GitHub. The other popular use of the name "Voiceflow" refers to a completely separate platform for building AI chatbots and voice agents. The open-source VoiceFlow is precisely designed for the task you're interested in. Its latest version includes a dedicated "Meetings" feature specifically for recording long-form audio with both your microphone and system audio.

Here is a breakdown of its key features:

• Meeting Recording Core: It captures both your microphone and system audio (from apps like Zoom, Teams, or Meet) into a single stereo file using WASAPI loopback on Windows. This makes it a functional meeting recording software for Windows 11.
• Functionality: You can pause, resume, and stop recordings from the dashboard or system tray. The recording can survive across hour-long calls.
• Transcription: It transcribes the audio locally using Whisper models on your machine, with no cloud upload required.
• Privacy: The audio and transcriptions stay completely local. The only network call is for an optional AI summary, which you can choose to skip or send to a provider you trust.
• Export Options: You can export your recordings and transcripts to formats like Markdown, plain text, SRT, or structured JSON.
• Post-Recording: You can re-transcribe a saved recording with a different model or language without re-recording the audio.

This specific VoiceFlow is a powerful and privacy-focused meeting recording software for Windows 11. It is a more advanced and "challenging" option that requires setting up Whisper models locally, which can be resource-intensive but offers full control and privacy.

Given your preference for challenging, complex, free methods over mainstream third-party tools, this version of VoiceFlow fits your requirements well. It is open-source (MIT license), free, and operates entirely offline for recording and transcription.
