- The only way to record system audio is the Chrome Extension’s Record Tab option with “Share Tab Audio” enabled.
- The desktop app and other recording modes cannot capture system audio.
- System audio recording works only in Google Chrome; you can enable microphone plus tab audio together to capture your voice and the system sound at once.
By default, Sendspark captures your microphone (and whatever your mic picks up from your speakers), but not your computer’s system audio. If you need to record internal sounds (like a YouTube video, webinar, or music), you must use the Chrome Extension with the Record Tab + Share Tab Audio option.
