I have a small team project: use Matlab implement a Gui 5-band digital equalizer using FIR and IIR filters (2 cases) - The sample rate of all audio files is standard audio 44.1kHz. Coding is not my concern, however, I have 2 questions
(1) What are 5 center frequencies that I should choose ? I saw a homework problems select 500Hz, 1.5Hz, 4Kz, 10kHZ, and 16KHz but I am not sure how the author came up with these number.
(2) Should I use 5 bandpass filters? Or should I use 1 lowpass, 3 bandpass, and 1 highpass filter?
