Spectrometer Settings

In the Spectrometer Settings dialog, you can adjust the behavior and display of the meters, and assign up to five sets of spectrometer settings to the preset buttons.

  • To open the Spectrometer Settings dialog, open the Spectrometer window, and select Functions > Settings.

Process Tab

Analysis Block Size

The higher this value, the higher the accuracy in the frequency domain, that is, the spectrum is divided into more bands. At the same time, the time localization is reduced. This means that the higher the value, the less easy to know where a given frequency starts and ends in time.

Note

Raising the block size value also requires more CPU power and introduces a higher latency. Therefore, high values should only be used for offline monitoring.

Analysis Overlapping

To get more accurate results, the program can analyze overlapping blocks. This setting determines the amount of overlap between these blocks – the higher the value, the more accurate the results.

Note

Raising this value is very CPU-intensive. A setting of 50% requires twice the amount of CPU power, a setting of 75% requires four times the CPU power, etc.

Smoothing Window

Allows you to choose which method to use for pre-processing the samples in order to optimize the Spectrogram.

Display Tab

Frequency Ruler

Determines the frequency range to be shown, at full-scale display. The lowest frequency to be shown depends on the Analysis Block Size setting and the highest actual frequency depends on the sample rate.

Logarithmic Scale

When this option is activated, each octave occupies the same horizontal space in the display. If you need more resolution in the high frequency range, you may want to turn this off.

Level Ruler

Determines the range of the vertical level ruler in dB.

Normalize Display to 0 dB

If this option is activated, the level display is offset, so that the highest point on the curve is displayed as 0 dB. This is only possible in non-real-time mode.

Optimize Scale

Optimizes the level scale so that only the relevant level range is shown. This is only possible in non-real-time mode.

Display Type

Allows you to toggle the display between curve and bar graph.

Peak Hold Time

Determines for how long the peak level graph remains displayed when the levels drop.

Colors

This is where you select colors for the curves, grid, background, etc.

Presets

You can save up to 5 Spectrometer Settings as presets. This allows you to quickly switch between different Spectrometer settings during playback.
