Note:

Some antivirus software may flag ReVox as a virus. I can guarantee that any version of ReVox downloaded from official sources (GitHub, Discord Releases channel) is completely safe. ReVox does not send any information anywhere, and only accesses the internet when checking for updates.

This can possibly be fixed with money, but this is a non-profit passion project with no funding.

Features

• Realtime recording of audio from:
  • An input device (microphone, audio interface, headset etc.)

  • Pre-recording buffer - record up to 5 extra seconds before pressing the record button
• Output to voice chat and recording apps
• Adding/removing/rebinding hotkeys
• Runs in background
• Highly customizable:
  • Soundboard:
    • Crop clips
    • Change clip volume
    • Record input device and system audio separately/together
