Ok,for those that not happy with rockbox equalizer,u can use my new equalizer setting.juz copy this *.cfg file to eqs folder.

after copy this file to that folder,open rockbox and choose settings--> sound settings.set like this:-

1.dithering= on
2.crossfeed= on
3.<in>
-direct gain= -1.5
-cross gain= -8.5
-High frequency attenuation= -16.0
-high frequency cutoff= 700hz
-stereo width= 105%
4.go to equalizer setting,choose "browse Eq presets" and choose SRS WoW presets. enjoy my setting. hope u all like it.

There are millions of people from the chinese forum waiting for this application and thousand of english people like me waiting too...

E2 forum outside this is not quiet at all, look here http://moto.it168.com/
E2 forum with 58884 topics and 1614195 posts! (still counting)

Therefore, porting this application to E2 should be a higher priority...

yeah, so many E2ers waiting for it , just like me

when we use this, does the previous EQ that u post earlier changed? or we can combine those EQ settings?

Comparing eXMMS to Rockbox just like comparing WinAmp to Real Player for me. If you prefer a "Powerfull Raw Sound" eXMMS is the Best, but if you prefer clean "almost perfect" Stereo Sound at "it's details" i think this Rockbox is the good one (thank's again to Mr. Blawkhawk for bring this wonderfull audio player to E680i).
I found some interesting EQ setting from Rockbox.org forum, check your head with these ones....

Below is a simple tutorial i copy/paste from Riovolution.com forum about setting your Parametric EQ, thanks to author (a Live Sound Engineer, Flattop100):



As a live sound engineer (yes, day job), I'll give you a quick breakdown on EQ, as I see it.

Bootnote: Sound is the most subjective thing on the planet/everyone's a sound guy--so in the end, do what sounds best to YOU. This tutorial is to give a basic understanding of how the EQ works, and to give you a starting point in making your own presets.

Now, I'm going to assume that you're EQing to make good stuff sound BETTER. I'm making my suggestions without any regard to battery life. The Rio Gods/Engineers are probably better equipped to answer that part of your question.

For starters, think of the default EQ--Bass and Treble. Since there's two "thingies" to adjust, we could call that a 2-band equalizer. Moving right along, we can call the "Advanced" setting 5-band: Low Bass, High Bass, Mids, Low Treble, and High Treble.

If you will.

I'm going to start getting technical now. I apologize in advance, but there's no help for it.

Back to high school science class...remember the part on sound and physics, which was taught at the end of the school year, and you spent most of class staring out the window at the women's track team?

Good times.

You should have been looking at the chalkboard. The teacher was explaining that sound is actually repeated pressure waves, traveling through the air and slamming into your eardrum. The slower the repetition, the "lower" the sound seems to be. Think of your average high school tuba player--the dude is pretty slow, ain't he? And he plays a low instrument...see the connection?

Since sound occurs frequently, the sound waves are often referred to in blue-collar circles as frequencies. However, scientists are white-collar, and like official sounding terms. Dr. Owit Hertz died for science, so his last name describes the number of sound pressure waves per second. The hertz was born anew! (I can see the movie now: The Passion of Hertz...)

Now, since we humans are nothing more than singing bags of meat, we're falliable. We can only hear between 20 and 20,000 hertz. (That's 20 sound pressure waves per second to 20,000 waves per second.) --That's average. Your actual mileage may vary.

OK, so I can't see the point of all this yet, but I can smell it.

With the 5-band EQ, you can choose what section of the audio range you're boosting or cutting; namely, the frequencies.

Some examples regarding frequencies:

A)A piano emits sounds from about 28 hertz up to 4200 hertz (4.2 kilohertz). (That's the fundemental, anyway; sound does this weird thing where it creates "overtones." Basically, if you have a low pitch and a middle pitch, the sound will add up (yes, like 2nd grade addition) to a high pitch.)
B)Most telephones reproduce 300 hertz to 3.5 kilohertz.
C)Your average home theater subwoofer reproduces sound from about 120 hertz down to about 40 or 50.
D) The typical human 'hiss' or 'S' sound runs the gamut from about 8 khz through 16 khz.

Now, it would be nearly pointless to boost or cut only one hertz--you would hardly notice it. So EQs adjust all the frequencies around a central point. This is part of the reason we refer to them as bands.

This is where the Rio Engineers' collective genius kicks in, and also where the "Width" setting on your EQ becomes important.

I need to introduce another scary music term, the "octave." In music, it refers to equal pitch intervals, one above the other. (Remember Dorothy in The Wizard of Oz? Sing the first word of Somewhere Over the Rainbow...you've sung an octave!) In sound (as opposed to music), we use the term 'octave' a little differently. Our ears work logarithmically, so that an octave is a frequency ratio of 2:1. Translation: There is one octave between 100 and 200 hertz, and one octave between 1000 and 2000 hertz.

The 'Width' on the Karma adjusts how wide an octave the EQ adjusts, in other words, how many frequencies are included in the boost or cut. On the Karma, you can go from 0.2 of an octave, to 4 octaves.

The best example I can think of is a dam breaking. A narrow octave width would sound like the first teeny tiny jet of water, hissing so softly you can hardly hear it. A wide octave width (really frikkin' wide), however, would sound like the whole wall caved in, a full "static on TV" type of sound.

Ouch. My head hurts. I hope this makes sense to some of you out there.

Maybe it would just be simpler if I gave out my EQ settings (using the default Senn earbuds). This won't sound as good to you as it does to me, since we probably wear our earbuds differently, and since we hear differently. On the other hand, I do get paid to make bad bands sound better, so take this as gospel.

Band: 12k
Boost: +3db
Width: 1.2

Band: 2k
Boost: +1db
Width: 1.2

Band: 400
Boost: -2db
Width: 1.2

Band: 120
Boost: +8
Width: 0.8

Band: 60
Boost: +8
Width: 1.0

I see that some "why do you EQ there?" might be helpful. These are kind of a 'default' I use on most headphones. Normally I use Shure e3's'--here are my settings for those.
12k helps "brighten" the sound. Cymbal crashes et al come through a little more.
2k adds a touch of presence as well--makes thing a little more undertandable.
400 is kind of a messy area, so I turn it down
120 is near the high dry bass sound, and I like bass. So I turn it up.
60 is the part of the kick drum sound that moves air.


Sorry for this message has taking a width page space, just want to share my opinion.....I LOVE MY E680i AND I NEED NO *******iPOD..

this is a complete different from my previous post.and i think this is better.

p/s:im using ogg format

[an_anda]

@naset
hahaha.. you didn't mean it just for me rite? you know what? it's a nice eq setting. INDEED. it's nearly to eXMMS sound quality. with a little more customization for own taste, wonderfull. oh.. now i can't wait for album art and lrc support. thx for the eq dud.

[endro]

thx naset for the explaination

but i prefer aac or mp3 than ogg

@erwin, woow a lot of eq there..

how many earphone do you have

[erwin]

@endro

No endro, i just use an original earphone with e.preset.cfg, good enough for me. Another *.cfg's just want to sharing to others. For me the original motorola earphone is better than Koss sparkplug. Senheisser is good but too expensive for me
