Multitrack Real-Time Spectrum Analyzer  

Put Your Eyes On The Mix

I developed MultiInspector for long studio sessions to assist your ears. MultiInspector visualizes up to 16 different audio signals in real time in one window only. Detect the overlapping frequencies in your mix!

Wusik Magazine about MultiInspector: "... MultiInspector is a very useful plug-in for any musician's tool-box. It is a helping hand towards a high quality mix."

Sonic Joy Award about MultiInspector: "... if your eyes love those almost-psychedelic spectrum analyzers, they'll love a Multitrack Spectrum Analysis even more."

MultiInspector comes with FFT mode and 31 Band Third Octave mode.


Choose Display Mode

H-Align/Overlay: In Third Octave Mode the width of the level bars is automatically adjusted according to the number of signals currently viewed. In FFT mode all signals overlap with semi-transparent regions.


V-Align: The spectral data is aligned vertically without space. This mode provides an instant overview of the overall frequency distribution.


V-Space: The spectrum of every signal is displayed in an own view. Views are ordered vertically.
