💡 Geek Tip: How to Achieve 100% Lossless Internal Audio Transcription?
Due to browser security policies, web pages cannot directly extract silent audio streams from files for transcription; they must rely on microphone array recording.
If you do not want ambient noise to interfere with transcription accuracy, or if you prefer not to turn up the speaker volume, you can change your operating system's sound settings by setting the default recording device (Microphone) to "Stereo Mix" or by using virtual audio routing software (like BlackHole or Loopback on macOS).
This way, the browser will directly capture the high-definition audio stream playing internally on your system, achieving a perfect and absolutely private offline audio transcription experience!
