 The bottom section of the Realtime tab is a Spectrogram panel, which allows you to analyze the waveform in more detail and helps you distinguish between noise and real earthquakes. You can adjust the colors by setting the Spectrogram gain field in `Settings->Realtime` so that background noise is displayed as a dark blue color.

 ## Drum tab
 
 The Drum tab allows you to browse the recorded data. Each line represents a time interval, with its start labeled on the left side (red numbers indicating hours and gray ones minutes). By default, each line represents 10 minutes of data. For navigation, you can scroll with your mouse, or you can use the buttons on the upper control panel. The `<` button will move the drum by one line, and `<<` will move it by 10 lines. By pressing the `Now` button, you will move the drum to the latest data. To access older data, you can use the `Goto` button and enter a specific date and time. 
 
 The drum can be configured by accessing `Settings->Drum`. By changing the value of `Gain`, you can adjust the scale of the waveform, and you can increase the `Decimate` field to lower the waveform resolution for better performance.
