# Analyzer

## Functionality

An Analyzer inspects the audio signal and displays various graphs to give an impression of the structure of a sound. It is able to draw a frequency response graph with adjustable accuracy and some other features as well as a phase correlation meter (goniometer). The frequency response shows how much energy a signal has over the frequency range. The goniometer gives a great impression of the stereo behavior of your track.

## Tips

The goniometer shows mono and stereo allocation of your audio signal. A signal mostly vertical around the center shows a high mono ratio while a signal with a wide spread from left to right displays a signal with a high amount of stereo (phase shift) signal. A signal only audible on the right speaker will produce a line from south west to north east and vice versa.

## Controls

- Source: Select the source for the frequency response graph.
- Mode: Set a mode for the behavior of the frequency response graph.
- Accuracy: The amount of visible frequencies. It also raises the delay of the displayed signal.
- Speed: How often a FFT is calculated and displayed.
- Hold: Draw a maximum peak graph above the output graph.
- Freeze: Freeze the graph in the actual state. An eventually displayed peak hold will continue in being pushed to the limit.
- Display: Stop displaying this widget.
- Level: Raise the level of the displayed signal.
- Dots: The amount of dots shown on the canvas.
- Fade: Choose if a fade out effect should be drawn (doesn't raise the overall CPU consumption) and how fast it should disappear.
