To correct what I wrote yesterday, I now recall that I had to tune the filters
when I first built the equalizer, so bandwidth would be the correct way to go.

@Ross, Nigel: Thanks for information. That was enlightening. :)
I'd be really grateful if someone would suggest a book audio filter
design where I can see all of these comparisons in form of
mathematical equations ?

Shashank: Analog filters—the kind in analog mixing consoles that mixed most of
what you grew up on—are IIR. So are most of their digital counterparts. So,
that's what people are used to.
Of course Ross is right about transients, depending on the amount of filtering
used, but linear phase has it

I would say not.
Most audio EQ filters don't have linear phase.
Additionally, the ear is very sensitive to acausality so, especially for

I had a doubt regarding filter designing.
Filters defined in Robert's cookbook are iir filters, i.e. Phase
respone is non linear.

I wrote several 1/3 octave EQs for cinema sound equipment.
They were all based in the main on the RBJ cookbook, the only changes being to
code in assembly language and make the calculation real-time adjustable.
I used a Butterworth characteristic Q and added two shelving filters 3k
