DDMF Plugindoctor v1.0.7 WiN

Plugindoctor fills a longstanding gap in the market: a cross-platform and cross-bitformat plugin analyzer for VST and AU plugins. Whether you are a plugin developer yourself who wants to thoroughly test the audio quality of your latest and greatest product, or a power user who wants to understand in more detail what exactly a specific plugin is doing to your precious audio material, Plugindoctor will help you find out!

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.
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)
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
If you’ve been looking for an all-encompassing plugin analyzer, this is it. A free demo is available, with an occasional processing interruption and a limitation of one plugin per session.
