VPI Audio Demos - Before and After demonstrations
On this page you can find some stereo files which will demonstrate the efficiency of the AudioCube's Virtual Precision Instruments (VPI's).
In order to compare the original files (left channel) with the processed ones (right channel) feed both channels into a console and use channel mutes to do "in-Sync" A/B-ing of the signal.
Switch your monitors to mono if you can or use the functionality of your wave editor. It is also helpful to loop the file playbacks.

* File is divided into four sections: 1. original stereo file, 2. restored stereo signal, 3. original material as mono sum (with an obvious loss in the high frequencies due to the azimuth error), 4. restored mono sum signal
