Abstract:
An audio system receives an input signal and, if the input signal has a sparse representation in the frequency domain, comprising components at at least one frequency of interest, the input signal is filtered in at least one band pass filter, such that only components at the or each frequency of interest are passed to an output. The operation is able in some case to analyse the input signal to determine whether the input signal has a sparse representation in the frequency domain.

Claim (Index 17):
A method as claimed in  claim 12 , comprising determining whether the input signal has a sparse representation in the frequency domain by:\n passing the input signal to a Fast Fourier Transform block; and determining a number of significant frequency components in an output of the Fast Fourier Transform block, and further comprising: if it is determined that the input signal has a sparse representation in the frequency domain, passing the output signal of the Fast Fourier Transform block to an Inverse Sparse Fourier Transform block to generate an output signal in the time domain comprising only the significant frequency components.
