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.
Comes as a 32 and a 64 bit executable.
Can load VST and (on Mac) AU effect plugins.
