[G1 Android Development] Meltus:
Uploaded one of many pre-made EQ settings. i will begin making more soon. This one is for you Drum n' Bass lovers out there, you know who you are :P although this sounds alright with other kinds of music (better than the flat EQ anyway) it is built predominantly for songs with low bass, i will be making more EQ settings, working on a good Rock one as we speak :)

​

You install this exactly the same as my AudioMods. REMEMBER!!! you will need my other modified files for this to have it's proper effect. using this alone will not increase the volume by much and might not even work

editing the EQ on the G1 isn't hard, but it's kinda long winded and requires a fair bit of tinkering.

i'll try and talk you through it as best i can :) i've already enabled the EQ, all you need to do is set it up to your needs.

step 1 - download included file (the EQ taken from V1 audiomod, so a slight volume increase)

step 2 - open it with Microsoft Excel

step 3 - Editing. The only line we're interested with is Row 6.

If you look at this line, it's all to do with the EQ. you have BAND1 all the way across to BAND8. basically, i wouldn't touch either BAND1 or BAND8 as these are only filtering out the really high and bottom end which you don't want.

ok, so looking at BAND2 we have:

BAND2 gain

BAND2 gain does essentially what it says on the tin, increases the gain/volume. REMEMBER!!! we're working in hex here, so the lowest is 0 and the highest is 0F (i think)

for those who don't know much about hex it goes:

0,1,2,3,4,5,6,7,8,9,0A,0B,0C,0D,0E,0F and then 10. but 10 loops back to 0's volume so 0F is as loud as you can go, and in comparison to V3, which is only on 0B, thats pretty damn loud.

BAND2 Freq

yup, you guessed it. this controlls at which frequency range the gain controlls. a lower number is lower and a higher number higher. This is pretty advanced tbh, i left it well alone lol :p

BAND2 type

this is a tricky one. I think this controls what type of EQ is happening at that point, e.g. a parametric, or it could even be Q control, i don't know.

we can judge by BAND1 and BAND 8 that type 1 is a low-shelving EQ and type 2 is a high-shelving EQ. basically, you don't want to use these. again, i left these well alone.

so yeah, thats about it really. Gain is the only main one you need to worry about. you also need a basic understanding of how an EQ works.

Increasing all the Gains to the same volume is fine, thats what i did in my mods, but that gives a very 'basic' sound. creating a Bass Boosting EQ, for example, would mean you increase the gain in the first few bands and keep them lower in the mid-high ranges.

research, some spare time and patience would come in handy :D

anyway guys, i hope this helps. feel free to ask any questions, although i wont be able to answer them until i get home from work tomorrow :p

here is a graphical representation of what i'm going on about. (i don't fully understand band 1 and 8 so i kinda left them out :))

BTW this diagram and the file included is based on V2 so, as you can see in the diagram, the volume is already boosted quite a bit. i wouldn't go much higher tbh. 0B is V3 and thats pretty distorted, so i'd say thats about the limit. unless you're very brave :P

i can't say this is spot on what happens but it's a very basic guide from my 'interpretation' of how the EQ works :P

i hope this helps some of you :D
