Similarly the "lower" level bands will also "get brighter". With the default setting of 20 dB, any frequency band that originally had (before amplification) a level of -20 dB or greater (and now, after amplification has a level greater than 0 dB) will be displayed as white. It does this by amplifying the signal by the indicated amount. Gain can be said to increase the "brightness" of the display. The default settings are can be viewed at Spectrograms Preferences or above on this page.Īs you can clearly see, the minimum and maximum frequency settings determine the minimum and maximum frequencies displayed, as indicated in the track vertical scale. This is how the track appears in spectrogram view, using the default settings. This is how the track appears in waveform dB view.
The level of each segment in dB is indicated by the labels below the audio track.
It consists of 10 segments of a sine wave tone at 2000 Hz, each 2 seconds long. To demonstrate how the various settings affect the appearance of an audio track in spectrogram view, we will start with this artificially constructed test track.
