How is audio signal processed?
Audio signal processing is used to convert between analog and digital formats, to cut or boost selected frequency ranges, to remove unwanted noise, to add effects and to obtain many other desired results. Today, this process can be done on an ordinary PC or laptop, as well as specialized recording equipment.

What is an equalizer in signals?
An equalizer is a device that can alter the spectral content of a signal.
