About the Spectrogram Display
The spectrogram shows a range of frequencies (lowest at the bottom of the display, highest at the top) and shows how loud events are at different frequencies. In general loud events will appear bright and quiet events will appear dark. The spectrogram can let you see at a glance where there is broadband, electrical and intermittent noise, and allows you to isolate audio problems easily by sight. RX features an advanced spectrogram display that is capable of showing greater time and frequency resolution than other spectrograms, allowing you to see an unprecedented level of detail when working with audio.
Transparency
The Spectrogram Display features a transparency slider which lets you superimpose a waveform display over the spectrogram, allowing you to see both frequency and overall amplitude at the same time. This can be invaluable for quickly identifying clipping, clicks and pops, and other events.
Configuring resolution
The Spectrogram Display can be configured to show a high level of detail for critical applications. For example, this is vocal recording represented with standard spectrogram settings and then with a high quality "reassigned" mode:
Regular spectrogram settings
Spectrogram in "Reassigned"
mode
In situations where you would like to see crisper detail, go to the View|Spectrogram Settings menu. There are presets in this menu for some of the more useful settings.
Changing Spectrogram Colors
RX's Spectrogram Display also allows you to choose from different color schemes. To choose from different color presets go to View|Spectrogram Settings.
