proper reconstruction of an audio signal. An audio signal is better reconstructed for the threshold value between (-0.02 to +0.02). Various performance parameters are measured which describe exact reconstruction of the signal. For proper reconstruction Orthogonal Matching Pursuit algorithm is used.

Abstract – The reconstruction of musical audio signal by using the Compressive Sensing technique is presented in the paper. Compressive Sensing can provide significant reduction of number of samples required by Shannon-Nyquist theorem. By reducing the number of samples, data compression is achieved along with the data acquisition. In

Compressed Sensing (CS), also known as compressive sampling, is a DSP technique efficiently acquiring and reconstructing a signal completely from reduced number of measurements, by exploiting its compressibility. The measurements are not point samples but more general linear functions of the signal.

Algorithm of compressive sensing The main goal of the CS algorithm is to obtain the exact reconstruction of a signal from a small number of samples. Using a traditional approach, the signal to be reconstructed is sampled periodically to digitize it. Furthermore, x(t) can be expressed as a linear combination of certain basis functions.

Compressed sensing: Find a sparse x such that y ≈SWx. (Note that A = SW.) A is usually much too large and dense to store explicitly, but we can form matrix-vector products with A and AT efficiently using FFTs, inverse FFTs, discrete wavelet transforms, etc. Stephen Wright (UW-Madison) Optimization and Compressed Sensing Gainesville, March 2009 13 / 37
