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. 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
