Features:
Highest quality, double precision FFT engine, independent stereo channel analysis
Linear analysis: magnitude and phase response using delta or random input signal
Harmonic analysis: highly accurate frequency response analysis to a sinusoidal input signal. Input strength and frequency can be varied for THD/THD+N calculation. Switchable intermodular distortion modus. Sweep function for fundamental and THD response.
Oscilloscope: watch what happens to a sinusoidal input signal in real time.
Dynamics: use a ramping signal to test compression or expansion, or an attack-release signal to check your compressor’s attack and decay curves.
Performance: how many milliseconds are really spent in your plugin’s audio processing callback (as a function of buffer size)
Ability to load two plugins in parallel for simultaneous analysis
Freely resizable user interface
Three quality settings, corresponding to three different FFT buffer sizes
Storage option of curves in Linear and Harmonic analysis mode for easy comparison of settings or of different plugins
Built-in screenshot function
Standalone version: comes as a 32 and a 64 bit executable

Plugin version: available in VST/VST3/AU/AAX format for parallel analyzing and listening in your DAW
Can load VST, VST3 and (on Mac) AU effect plugins

If you’ve been looking for an all-encompassing plugin analyzer, this is it.

IMPORTANT NOTE: Uninstall/remove previous version before install.
