Description: 

This plugin performs spectral analysis of a single audio channel. It does not affect any changes to the input signal, so can be placed anywhere where the metering is needed.

Common controls:

• Bypass - bypass switch, when turned on (led indicator is shining), the plugin does not work.
• Mode - depending on operating modes, different analysis can be performed:
• Analyzer - performs analysis of a single audio channel.
• Mastering - performs less accurate but more demonstrative analysis of a single audio channel.
• Spectralizer - draws spectral analysis of single channel.
• Freeze - immediately freezes all frequency graphs.
• Spectrogram - the rendering mechanism of the spectrogram in the Spectralizer mode:
• Rainbow - each dot on a spectrogram changes it's color's hue component depending on the amplitude of the signal starting with Hue of the selected channel.
• Fog - each dot on a spectrogram changes it's transparency depending on the amplitude of the signal.
• Color - each dot on a spectrogram changes it's color's saturation component depending on the amplitude of the signal.
• Lightning - each dot changes it's solor's lightness component depending on the amplitude of the signal, the Hue is interpreted as a middle value of the possible value range.
• Lightness - each dot changes it's solor's lightness component depending on the amplitude of the signal, the Hue is interpreted as a maximum value of the possible value range.
• Measure - Additional button that enables horizontal measuring line.
• Log scale - the way how dots on the spectrogram are rendered. When button is down, logarithmic scale is used to translate amplitude into dot's color.
• Line size - the combo box that allows to change the thickness of the lines on the spectrum graph.

Channel controls:

• On - turns on the analysis of the channel.
• Hold - forces the frequency graph of the channel to freeze.
• Shift - allows to adjust the gain of the channel.
• Preamp - allows to adjust the overall gain of the analysis.
• Selector - allows to select the available frequency for level metering.
• Reactivity - the reactivity (smoothness) of the spectral analysis.
• Level - the level of the selected frequency.
• Window - the window applied to the audio data before processing.
• Tolerance - the number of points for the FFT (Fast Fourier Transform) analysis.
• Envelope - the envelope compensation of the signal.
• Zoom - zoom fader, allows to adjust zoom on the frequency chart.

Meters:

• Frequency - the current frequency selected by Selector control.
• Level - the level of the selected Frequency.
