Root [APP] Android DSP (Equalizer) for Froyo

Only got to play with it for a minute but it works on Lithium Mod (using Gala). Played music for about 15mins no problems. This is exactly what I've been waiting for. Hope it gets updated with more bands than 5.
 
ok, being the farthest thing from an audiophile possible, I don't have any idea what an equalizer does, besides (ready for the stunning leap in logical thought?) equalize music volumes.

Is that a big deal? its seems to be because I hear people clamoring for it all the time. Anyone care to explain further?

It allows you to emphasize which frequencies (i.e. bass, treble, midrance, etc) are louder/softer, which can make a big difference in sound quality for some genres of music.

Also, it's a pretty elementary function of any modern music player and it's just kind of sad that Android doesn't have one built in.

Its like a separate volume control for each frequency range. So set as the picture shows the lows and highs are increased. Its llike bumping up the bass and treble. Certain music sounds better with certain settings. Its mainly all user preference though.

I like the bass and treble bumped up b/c I llike the bass drum and cymbols to sound more prominent, and also listen to music with soprano singers.

Dunno if anybody mentioned it yet but fully working on BB v.04. Simple update.zip. Looks awesome with the X theme/rom. Thanks for satisfying the audiophile in us all.
 
So is this fixing the "crappy Pandora/streaming radio playback" that a lot of users on here are complaining of? I've personally never experienced degraded playback of Pandora or Slacker on my Droid running any 2.2 ROMs. But I might give this a try anyways just because the more features, the better for me :D.

Also, Fab, what is the "H" above your network activity icon in the notification bar?

No, the issue with Pandora/Slacker/Anything that uses AAC+ files is detailed here:
Issue 9308 - android - eaac+ and aac+ decoding sound quality problems (Android 2.2) - Project Hosting on Google Code
Note, this is a bug in all versions of Android OS 2.2, and you do experience it. It is not possible for you to use 2.2 and not experience it. Your inability to hear it is amazing, because it makes all AAC+ content sound tinny and overblown.
The only current way to work around this is to disable the new (in Froyo) stagefrigth media framework as detailed here: [FIX] Fix poor AAC streaming performance (Pandora, Slacker, etc) on Froyo - xda-developers

Now, I do wonder how this app - equalizer - interacts with disabled stagefright...

I just yanked the SS from the website. I'm assuming that's the dev's phone.

But the H stands for HSDPA. Just another, faster 3G for GSM networks.
 
Well,trying it now on 5.0.8...we'll see if she flies....

Nope,no go. Boots and sits stuck on the M logo....that totally sucks. Figures the friggin EQ I've always wanted is on a rom that refuses to work on my Droid.....

If I do experience it, then it must be negated by my cars own amp and equalizer (in the head unit) because it still sounds great in my car. I haven't tried listening to it on anything else. So you can cease to be amazed by my "inability to hear".

So does this affect all other phones running 2.2 too, then?
 
OMG OMG OMG OMG OMG OMG OMG OMG OMG OMG OMG OMG

Thank you, Android DSP team, Fab, and anyone else who has been helping with this project!!!!

/runs off to play with real music....
 
Yes... oh yes... one of the two big things audio-wise I've been waiting for since I got my Droid.

The next thing I want is a volume slider so that I don't have to choose between "this is a bit too quiet to enjoy" and "MY EARS ARE BLEEDING". Yes I could just change the overall gain with the equalizer, but an actual volume slider would make the output sound much cleaner and less clipped. Also, it's much easier to move a volume slider to compensate for differences in gain between albums than to slide 5 bands in an equalizer constantly.
 
im using kangerade v5.0.9 with P3 1.25ghz LV, works great but at the 3 loudest volume tiers it sgets reallly crackly and tinny,

also im not the greatest with these things but if anyone has some "presets" to share for certain types of music that would be awesome!
 
Anyone got any ideas of a 2.2 that might work on my Droid? I've tried cm6 and lithium and both freeze it up tight and batt pulls galore,even after wiping. I really want this EQ
 
Do you need Root explorer to back up thelibaudioflinger.so file? and access the DSP.apk? :confused: Ir thats a must I'm screwed lol I'm broke to to buy root explorer >.<

In terminal emulator
Code:
su
mount -o remount,rw -t yaffs2 dev/block/mtdblock4 system
busybox cp /system/lib/libaudioflinger.so /system/lib/libaudioflinger.bak
mount -o remount,ro -t yaffs2 dev/block/mtdblock4 system

And Damn that took forever doing it from my phone. Haha.

Jajajajaja Thank you I will try that tomorrow.
 
and use astro. Or something to navigate to the file to make sure it copied it because it won't say if it did or not.

Did you try the leaked OTA? I'm pretty sure that HAS to work on your phone, otherwise it would be considered defective :)

Never experienced that issue here either (now running the new FRG22). I'm a professional musician, audiophile and technogeek... so I'm pretty confident I would immediately have a gigantic issue with it. No problem on headphones, home stereo, or car (just back from a 30 hr road trip streaming Pandora for much of it).

Now, I didn't try the linked test files before installing this equalizer, but again, I'm hyper aware of sound quality by profession. :cool: Maybe it's a non issue with an equalizer because the problem files are rendered differently spatially (esp with the virtual effect turned on), but I think it's more likely this problem doesn't present itself on every phone.

Yes, it affects all other phones.
and no, its not possible for your car stereo to compensate. You just have shitty hearing :)

OMG, that is not possible.
This is a bug in the OS.
If I seem overbearing on this, its because you people don't seem to get the issue. IT IS A BUG IN THE OS. It affects every phone running 2.2. PERIOD.

As for you not hearing it, well, your "golden ear" must be more like tin, because its immediately apparent to me, and many others.
And no, the EQ doesn't fix the issue. Look, the stagefright media player (built in API in the OS that actually plays the music) doesn't properly play AAC+ files. There is no way for a DSP to magically add back in or fix the improper decoding. All the music player apps rely on the OS to actually play the files, therefor, they are all affected.
Slacker won't have this issue when streaming over WIFI, as it uses MP3s then.
MP3s playback is not broken. But Slacker (cacheing and cell streaming), Pandora, mspot, last.fm, etc all use AAC+

Let me re-iterate: IT IS NOT POSSIBLE FOR YOUR 2.2 OS PHONE TO NOT HAVE THIS ISSUE.

I don't really care if you can't hear it. I can, and I'm tired of this issue being mis-represented. Its not just applicable to "some phones", but to ALL.
 
Finally got cm6 rc2 to work, although sporadically-rc1 never would. Got this eq up and running, and yea there's crackling at various volume levels. Appears it's a work in progress yet but still the first functioning eq.
