Spectrum Analyzer Screen

Select the Spectrum Analyzer from the Analysis drop-down menu. The graphical representation indicates the level of an audio signal at various frequencies. The analyzer performs a Fast-Fourier Transform (FFT) on the input audio to convert it to frequency information. This is put into individual bands and displayed as a bar graph. A spectrum analyzer designed to indicate the level of audio at 31 different frequencies across the audio range is also known as a 1/3-octave spectrum analyzer. Up to 61 bands (1/6th octave) are supported in mono mode, and up to 31 bands (1/3rd octave) are supported in stereo. 10, 15, and 20 bands are also supported.

Range (–96 dB to –30 dB)

The analyzer range enables you to adjust the viewing range of your signal between –96 dB to –30 dB.

Left/Right Buttons

Select either right or left channel inputs for viewing.

Mono

The mono button enables a mono view.

Stereo

Use to select a stereo view.

Freeze

The freeze button will freeze the current frame to let you take a closer look at your signal in the spectrum graph.

Peak

When the Peak button is enabled, each band’s meter displays its own peak, presented as a small individual yellow hash mark at the top of each meter. When a band's peak is reached, a hash mark appears and then gradually decay.

Ref

Reference is a hand reference point represented as a red line on the analyzer graph that can be set anywhere from –60 dB to 0 dB. Use this to maintain a relativity reference that most suits your need.
