Audio Signal Processing in MATLAB

Contents hide

The Audio Signal Processing group at IEM is, in particular, concentrating on sound analysis, sound modeling, and the extraction of musical or speech-relevant features and characteristics. The topic comprises methods of time-frequency processing, multi-rate processing, and adaptive filtering.

So in this, we create a simple sound with noise and we filter this noise using a bandpass filter. This is a subfield of signal processing that is concerned with the electronic manipulation of audio signals.

Application

Signal processing is an engineering field that focuses on the computational methods for intentionally altering sounds, methods that are used in many musical applications.
