<p><b>Detailed: </b>LSP Spectrum Analyzer x1 - Spektrumanalysator x1 (SA1)</p>
<p><b>Formats: </b>LADSPA, LV2, LinuxVST, JACK</p>
<p><b>Categories: </b>Analyser, Utility, Spectral</p>
<p><b>Developer: </b>Vladimir Sadovnikov</p>
<p><b>Description: </b></p>
<p>
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.
</p>
<p><b>Controls:</b></p>
<ul>
<li><b>Bypass</b> - bypass switch, when turned on (led indicator is shining), the plugin does not work.</li>
<li><b>Mode</b> Depending on operating modes, different analysis can be performed:</li>
<ul>
<li><b>Analyzer</b> - performs analysis of a single audio channel.</li>
<li><b>Mastering</b> - performs less accurate but more demonstrative analysis of a single audio channel.</li>
<li><b>Spectralizer</b> - draws spectral analysis of single channel.</li>
</ul>
<li><b>Spectrogram</b> - the rendering mechanism of the spectrogram in the <b>Spectralizer</b> mode:</li>
<ul>
<li><b>Rainbow</b> - each dot on a spectrogram changes it's color's hue component depending on the amplitude of the signal starting with <b>Hue</b> of the selected channel.</li>
<li><b>Fog</b> - each dot on a spectrogram changes it's transparency depending on the amplitude of the signal.</li>
<li><b>Color</b> - each dot on a spectrogram changes it's color's saturation component depending on the amplitude of the signal.</li>
<li><b>Lightning</b> - each dot changes it's solor's lightness component depending on the amplitude of the signal, the <b>Hue</b> is interpreted as a middle value of the possible value range.</li>
<li><b>Lightness</b> - each dot changes it's solor's lightness component depending on the amplitude of the signal, the <b>Hue</b> is interpreted as a maximum value of the possible value range.</li>
</ul>
<li><b>Log scale</b> - the way how dots on the spectrogram are rendered. When button is down, logarithmic scale is used to translate amplitude into dot's color.</li>
<li><b>On</b> - turns on the analysis of the channel.</li>
<li><b>Hold</b> - forces the frequency graph of the channel to freeze.</li>
<li><b>Hue</b> - allows to adjust the color (hue) of the channel.</li>
<li><b>Shift</b> - allows to adjust the gain of the channel.</li>
<li><b>Preamp</b> - allows to adjust the overall gain of the analysis.</li>
<li><b>Selector</b> - allows to select the available frequency for level metering.</li>
<li><b>Reactivity</b> - the reactivity (smoothness) of the spectral analysis.</li>
<li><b>Level</b> - the level of the selected frequency.</li>
<li><b>Window</b> - the window applied to the audio data before processing.</li>
<li><b>Tolerance</b> - the number of points for the FFT (Fast Fourier Transform) analysis.</li>
<li><b>Envelope</b> - the envelope compensation of the signal.</li>
<li><b>Zoom</b> - zoom fader, allows to adjust zoom on the frequency chart.</li>
</ul>
<p><b>Meters:</b></p>
<ul>
<li><b>Frequency</b> - the current frequency selected by <b>Selector</b> control.</li>
<li><b>Level</b> - the level of the selected <b>Frequency</b>.</li>
</ul>
