| Summary: | In this paper, investigation is made on the
application of an adaptive FIR filter to estimate the desired audio signal, in this case speech signal, from an input of the signal contaminated with background music. Results show that the signal to noise ratio is significantly increased. Informal listening tests also show that very significant improvement to the quality of the recovered signal can be achieved. The condition for the success of the method hinges on the availability of information of the interfering source such as the background music. |
