Overview
The spectrogram and waveform display window combines an advanced spectrogram with a transparency feature to allow you to view both the frequency content and amplitude of a file simultaneously.
Transparency
The transparency of the waveform and spectrogram can be adjusted with the transparency slider to the lower left of the display.
Zoom
To the lower right of the display, you will find horizontal and vertical sliders. The horizontal slider will affect how much of the time ruler is represented on the screen. The vertical slider controls the frequency range shown in the spectrogram.
You can also zoom by clicking on a ruler and moving your mouse wheel.
Selection Modes
The spectrogram display features selection tools that allow you to precisely select both by time and frequency. The selection tools can be found to the lower right of the spectrogram window.
Time Selection - Select a range of time within the file (horizontally within the spectrogram).
Time and Frequency Selection - Lets you select a range of time within specific frequencies (vertically and horizontally within the spectrogram), for example to process intermittent noise which falls only in a certain frequency range.
Frequency Selection - Lets you select an area of the file by frequency only (vertically in the spectrogram).
Zoom Button - Toggles zooming mode. When in zooming mode, you can zoom in to time, time/frequency, and frequency areas. Hold the alt key and click to zoom out.
Advanced Spectrogram Settings
Our spectrogram has been designed to provide more
sharpness and detail than other spectrograms. To adjust advanced settings like
FFT size (frequency resolution), window and colors, go to View | Spectrogram Settings
