Abstract :
We demonstrate real-time audio signal restoration using techniques from compressive sensing (CS) and sparse signal recovery. In particular, we show an FPGA prototype implementation of the approximate message passing (AMP) algorithm, which removes clicks and pops from corrupted audio signals.
