Prioritize How It Actually Sounds

The dB displayed in your browser is not a measurement from a calibrated sound level meter, but rather an indication of the input level within your device. Rather than comparing absolute values ​​between devices, it is used to compare before and after changing positions and settings in the same environment.

Confirmation procedure

  1. Start your microphone and choose the input device you want to use.
  2. Look at the meter and spectrum in silence to check for constant noise.
  3. Speak at your normal volume and check to see if the input level is too low or stuck at the upper limit.
  4. Make a short recording and use your earphones to check for intelligibility, noise, and dropouts.
