BASQ Audio has introduced a VST3/AU plugin designed to analyze other audio plugins.

By inserting FxDiff around the plugins under test, you can thoroughly examine its behavior and effects. Additionally, FxDiff serves as a level matcher, enabling precise comparison between bypassed and processed signals.

FxDiff features

  • Frequency Response Analysis: Conduct gain and phase analysis of any plugin loaded in DAW. You can even visualize the Gain curves of EQ plugins withou EQ curve GUI.
  • Compression and Distortion Analysis: Examine the compression curves of compressor plugins and the non-linear distortion curves of saturator plugins.
  • Spectrum Analyzer : Compare the frequency domain characteristics between bypassed and processed paths to identify the added effect by the plugins.
  • Oscilloscope : Assess the time-domain waveform and differences between the bypassed and processed signals for a comprehensive understanding.
  • Level Matching: Automatically match the level between bypassed and processed paths, ensuring accurate evaluation of the plugin’s effect without level discrepancies.
  • Auditory Comparison: Listen to the differences or blend between the bypassed and processed signals.
  • Signal Generator: Generate basic test signals, such as sine waves, noise, or specified WAV audio, to use in place of the input signal.

FxDiff is available for Windows and Mac (VST3/AU), priced $39 USD. A free 30-day trial version is available to download.
