Spectrogram Settings

The option Show spectrum (dBFS vs frequency) at the bottom of the box will activate a real-time spectrum display window showing the mean and peak spectrum along with the peak frequency and amplitude. Amplitude and frequency can be measured using the mouse cursor. The combo box titled peak hold duration determines how long the peak amplitude will be held. During the monitoring, right-clicking at the spectrum display will reset the peak hold values.

The level meter mode list box allows switching between the peak level and the rms level calculation method on the recording level meter display. The default peak level option allows monitoring the dynamic range usage and helps to recognize clipping, while the rms level option facilitates precise level measurements.
