Spectrogram displays frequency information over time. The horizontal axis is time in seconds (s), the vertical axis is frequency in Hertz (Hz), and the colour represents the frequency's magnitude (dB). The louder a certain frequency is, the more intense its colour.
| Spectrogram Settings | |
|---|---|
| Setting | Description |
| Automatic full frequency range | Automatically sets the frequency (vertical) axis range to match the current sampling rate of the file. For a sampling rate of 44100Hz the range is set from 0 to 22050Hz (the Nyquist rate). |
| Fixed frequency range | Allows the frequency (vertical) axis range to be set manually, giving more frequency detail within that range. |

From (Hz), To (Hz) |
Sets the frequency range when Fixed frequency range is selected. |
| Scroll speed | Sets the number of vertical strips to draw per frame, increasing the time resolution of the spectrogram. |
| Show axis | Shows numbers on the horizontal and vertical axes and the colour scale legend at the bottom of the visual. |
| Gray-scale | Uses a gray-scale gradient instead of colours. |
