A question about EQ.

Hi,

Who could tell me some typical EQ mode's frequecy response, just like Jazz, rock, and POP etc?

Thanks!

IMHO the best EQ mode is flat

Do you want to correct a non-linear frequency response?

If you use a 31-band-EQ you would have to set up a test signal consisting of 1/3 octave band noise and a reference (e.g. band noise around 1 kHz)
switch between both of them and adjust the corresponding eq control until both signals sound equally loud. Then go on to the next noise band.

The result would be the best possible setting for your speakers/headphones, totally independent of the type of music.

An honest acoustical engineer would tell you first, that the process is hopeless without an accurately calibrated measurement microphone and secondly, that the results will be correct only for exactly where you made the measurements. Move your head a few inches one way or another, forward or backward, and all bets are off. The only really useful process is to treat the room and forget the EQ toys. EQ is properly employed on a track by track basis as part of mixing, or in tweaking a final mix during mastering, before the music is published.

Ideally, the function of an equalizer is to remove the damping/resonance effect of the room, provided you pump in a true white noise through a flat-response speakers.

But like AndyH-ha said, it is impossible to have an ideal equalization throughout the entire room. So acoustic engineers always demand to know just where the listeners will be listening, and tries to find an average EQ setting that will approximately compensate overdamping or overresonance within that area.

It is practically impossible to completetely compensate the damping/resonance effect.

Equalizing a room is ideally a two step process:

1. Equalize the speakers so that it provides a flat response throughout the main audible/emotional spectrum.

2. Equalize the room so that the room provides a flat response.

Of course, steps 1 & 2 are commonly combined into one step, for practical reasons. After all, whatever equalization performed on the speaker will directly interact with the room's response.

Now after all that has been said...

If you want to know the right Jazz/Rock/Pop setting to 'enhance' your listening experience, in other words you are totally uninterested in a flat room response (i.e. you don't want to listen to the music as it was recorded)...
