Abstract
We demonstrate the restoration of audio signals corrupted by clicks and pops using techniques from sparse signal recovery and compressive sensing. The demonstration features real-time signal restoration using the approximate message passing algorithm on an FPGA prototyping board. To highlight the restoration performance of our implementation, we remove clicks and pops from old phonograph recordings in real time.
