A good way to get an idea of the declipping performance of SPADE is to listen to some examples.

Results for different input clipping levels

Click on the examples below to compare A-SPADE with another recent algorithm, Consistent IHT, as well as with the Adobe Audition DeClipper (TM) software.

Two example audio tracks are clipped to prescribed SDR (Signal to Distortion Ratio) values and processed by the different algorithms. The original (unclipped) tracks and the clipped versions are given as references along with the achieved declipping results.

Results for different types of music samples

A second demonstration compares the declipping performance of three algorithms: Consistent IHT, A-SPADE and S-SPADE).

Ten example audio tracks are clipped to 3dB SDR and processed by the different algorithms. The original (unclipped) tracks and the clipped versions are given as references along with the processing results achieved using another commercial software.
