Abstract

The software is devoted to the restoration of clipped samples of audio signals. The signals are processed block-by-block and then reconstructed using the OLA scheme. Sparsity of the signal in a proper representing system is utilized. The system and its redundancy can be set in the software as well as the size of processed blocks and parameters concerning the analysis and synthesis window. The software package contains two main algorithms: A-SPADE for analysis approach and S-SPADE for synthesis approach. Implementation is done in MATLAB.
