A few basic signal checks on your recording
What this check shows
- Measured values of your recording: pitch, level and background noise.

What each measurement means
- Pitch (F0)
- The pitch of your voice, in hertz. The typical range covers the middle half of your voiced speech.
- Speech level
- Average loudness of speech relative to the loudest possible digital signal (0 dBFS).
- Background noise (estimated)
- How far the background noise, measured in the pauses, sits below your speech. Phone noise reduction can make this gap look larger than it is.
- Pitch range over the clip
- Lowest to highest pitch, leaving out the extreme 5 % at each end.
- Brightness
- Where most of the sound energy sits between low and high tones: higher means a brighter sound.
