DDMF has released version 1.0.8 of Plugindoctor, an all-encompassing plugin analyzer that lets you test the audio quality of a plugin and see in detail what exactly is done to your audio material.
The updated version now comes with hardware analysis support.
Just attach a piece of outboard gear with send and return channel to your audio interface, select the corresponding in- and outputs in PD’s settings, and enjoy the same thorough analysis that so far has been only available for plugins.
Additional new feature: more than one curve can be stored for easy comparison, and not only in linear analysis, but also in harmonic analysis mode.
Plugindoctor for Windows and Mac (VST/AU) is available for $19 USD.
