Root Milestone Audio Equalizer [BETA]

[Fabolous]

This mod is only for rooted Droids, and there are a lot of adb/terminal commands involved, so it is not for the faint of heart. What it does accomplish though, is well worth the work (IMO). Anyways, I don't think I can post the link, because it is a Milestone port, and therefore not open source, but let's just say you guys can find it. Here are some great instructions, credits to diakonv at Alldroid.

I extracted the modified.zip to a temporary folder on my computer.
I opened a command prompt and changed directories to that temp folder.
In the command prompt I typed:
adb push libaudio.so /sdcard/libaudio.so
adb push libaudioflinger.so /sdcard/libaudioflinger.so
adb push ap_gain.bin /sdcard/ap_gain.bin

then I backed up the originals to my sdcard by typing:
adb shell
su
mount -o remount,rw -t yaffs2 /dev/block/mtdblock4 /system
cp /system/lib/libaudio.so /sdcard/libaudio.so.bak
cp /system/lib/libaudioflinger.so /sdcard/libaudiofingler.so.bak
cp /system/bin/ap_gain.bin /sdcard/ap_gain.bin.bak

then I copied the modified files over:
cat /sdcard/libaudio.so > /system/lib/libaudio.so
cat /sdcard/libaudioflinger.so > /system/lib/libaudioflinger.so
cat /sdcard/ap_gain.bin > /system/bin/ap_gain.bin

mount -o remount,ro -t yaffs2 /dev/block/mtdblock4 /system
reboot

I might add that you can put the audioeffect.zip in the same folder as the modified files, and then:

adb push audioeffect.zip /sdcard/audioeffect.apk

Then, after the reboot after you've modified your audio libraries, install the audioeffect controller.

So far, initial testing has given me great results with the '3' media player. I use a custom effect of 'wide' surround mode and 'bass punch'. Makes my music sound even better through my Dre's.

After some more testing, I've noticed a little hiss in between songs, but it's not a big deal considering the much more noticeable increase in sound quality.

Finally! Sweet. Gonna be doing this when I get home tonight.

 

[droidpcguru]

Done ..but with Connectbot..

Seems to make one heck of a difference in just the onboard speaker. I'm going to hook it up to the AUX IN on my stereo and see what happens..I'm sure I will be a happier camper

EDIT: All is working well.. MAJOR difference. I can finally make my Droid sound wayy better than a plain old tin can

 

[brettlewis]

will something like this be put in a rom? or become standard to the vanilla install?

 

[eL777]

Wow... never thought I cared about an equalizer until I tried this. Big difference indeed... pretty awesome. I recommend it

I'm sure it'll find its way into Pete's next ROM.

hoooray! maybe i wont have to get new car speakers again because my phone is messing with me.

If your saying that hoping it won't crackle or pop.. it still does.. assuming of course you aren't using stock 2.0.1 kernel.

JUST finished rooting for the first time. Then I come on and see this post,and man..this will make rooting WAY worth it!! Problem is,I have NO clue what to put where or to type. I saw the initial post here but am totally illiterate as far as commands go where,etc etc. Guess I'll just wait for a nice,neat package deal that does it for me....

 

[brettlewis]

yeah, im going to wait for a package with it. but as far as the terrible sounding audio input, what can I do. It is driving me mad!

 

[alostpacket]

Yes!

Thanks for the heads up fab! And for copying the adb commands, I never remember the mount one heh.

 

[alostpacket]

By the way I'm all about the Wide setting and Extreme Bass setting.

Baby got back.

 

[eL777]

Ok, did a test with this in my car (basic speakers but decent player)... put my droid on wide surround and bass punch... holy crap what a difference. I even put everything back on normal on the droid and tried to up the bass and stuff with my player but using the droid EQ always sounded better. I will also note that I do not experience the cracks and pops on pandora and I am using an OC kernel. This might be because I had the volume NOT at MAX on the droid...I did a test and if the volume is at max on the droid, I definitely get pops and crackles, but at a lower volume I didn't hear any whereas before I heard a few here and there. However, this test was only about a 20 minute test.

Can this be done just moving/copying files through andro or rootexplorer? I notice you can get to all the files on the phone itself, or is this a shell thing only?

A couple things regarding this.. guess I'll leave it alone.
From the Alldroid thread..

Seems to work only with 2.0.1.
Known bugs -
Speaker phone may not work.
Cannot adjust volume during a phone call.

 

[Sportster]

I'm dying to try to do this but I just don't know how to get that on my phone. I've been waiting for a EQ since I bought this thing and to now have one in view is KILLING me,lol. I'm rooted..what else do I need to get this on my phone? I don't have a ROM on there yet but am considering BB as I've heard much good about it. Will this work with BB? And exactly what does it EQ? Pandora? Slacker? 3? These are what I've got on my unit as well as DroidLive.

Nice. Extreme bass is a little too much for me, but it's probably cuz my Dre's overemphasize bass to begin with. I would imagine that it sounds pretty nice with a mid range set of ear plugs (such as my Koss's)

you can use rootexplorer to copy the files over to the correct directories, but make sure the file permissions are correct when you finish copying them over otherwise your phone might not boot correctly.

Ehh.... I use speaker phone quite a bit. Not being able to adjust volume in calls wouldn't bother me much, I just max it out anyways. If that speaker phone bug gets fixed I might look into this.

 

[BigMace23]

Looks good, but I am gonna wait until the bugs are worked out before I look to put it on my droid.

 

[shrink57]

Has anyone tested the speakerphone with this hack? I use the speakerphone at work all the time and for me losing it would be a deal breaker.

 

[Fabolous]

Just called my voicemail and the speakerphone works fine. I cannot, however, adjust the volume mid call (it shows the bar but no changes actually occur)

Thanks for the heads up. I guess my Droid is scheduled for surgery when I get home tonight.

Yep. I actually listen mostly to Techno so often times the more bass the better. Though I bet that punchy bass eq would sound good with your hip hop. It seems like a small band pass right around the low mids. It's just awesome to have these options now though. All we need now is a graphic eq.

Finally got around to installing this today (never play with the console before). Thanks for all the help!!!!

 

[shrink57]

I spoke too soon. After installing the equalize and settings app I seem to have lost the ability to hear my calls over Bluetooth (Motorola T505). I am unable to hear a thing. I reflashed Sholes 2.05 and it is working fine again. Going to try agin....
