hi every body.
please, could any one tell me something about audio equalizer?
how it works and how to implement in matlab programming.
just a little hint!

 

Look into "bandpass filters". That is essentially what equalizers are - a collection of adjustable gain bandpass filters with a summing amplifier at the output.

 

Hello,

For ideas for the filters look at this page.
