[APP] VoodooEQ 1.6 - 13-03-22 - control the voodoo sound hardware equalizer

FadeFx · Feb 12, 2013

Hi, after doing a similar app for the i9300 and its scoobydoo sound voodoo derivate, i modified my app to be compatible with the i9000 and voodoo sound.
It is so far feature complete and all is working, if you have any suggestions, feel free to ask.

Attention, LaboDJ Slim gapps are not supported, this package is missing something that prevents that VoodooEQ can be installed

Features:

# control the 5 band hardware equalizer
# analog gain
# negative digital gain
# stereo expansion
# stereo width

# notification to open eq (if enabled in "more" screen)
# set values at boot (if enabled in "more" screen)

#2 fixed Presets
#3 customizable Presets (hold preset name to rename)

Screenshots

Download version 1.6

this is the first release, it is so far feature complete and all is working, in a later version i will try to pretify it a bit.

Installed on my sgs-I9000/JB4.2 (hellybean4.2.1 by franzyroy). working good.I like its transparency.Could you explain or give a link to read more about the setings (for example, what is negative digital gain?)
thank you

please redownload, i made a design...

yeah,better now!
Only I see that it doesnot appear in recents panels (not big deal). I know it is personal hearing preference but may be a sugestion for the settings? you know sgs is not stereo and its sound is...difficult to see the differences (except I use external speakers). I shall try first as your screenshots!
tks again

What you mean sgs is not stereo? I am pretty sure it is...

Btw, one more update to come later, had a bug with restore on boot...

Thanks for this app, i really like it!

I think the EQ's of the audio chip are parametric, do you think you could implement that as i would like to adjust the frequency bands

Re: [APP] Voodoocontrol - control the voodoo sound hardware equalizer

As far as I know sgs has the capability of stereo but at least my phone has one speaker, so it is not stereo, I can see the the difference with the earphones or external speaker,correct me if I am wrong. also my phone has low sound level, you must be close to it to hear music.
For your app now, From first use i notice a small problem with analog gain slider. I used earphones to hear radio and i had no sound, i realise that the voodoo headphone amplifier was too low,i increase it but i had to decrease in this app the analog gain. I notice that had delay to increase/decrease and the slider need to be moved very little or slow in order not be very high or very low,looks as if scaling is wrong. Shall try it later with speakers. I hope I was somehow clear.
Thank you, this app is great, today I enjoyed music (earphones)

Suggest you check permissions and/or clear its data.I don't have problem ,I suppose you have installed voodoo sound and kernel ?

Can you add reset button?

Yes it is, but i have no idea how it works yet, i will have a look later...

Yep, noted on todo list...

Also i think of adding some presets.

In this Datasheet i found that the EQ center frequencies and bandwidths are fixed in default mode, but can be programmed in reTune mode. Don't know if you are working that low level oriented or if you leave this to voodoo sound, meaning you would have to find out how voodoo configures the eq mode.

Furthermore a graphic display of the eq settings would be nice, don't know if you are familiar with the terms.

Let me know if i can help you with anything!

Anyway thanks for this app, it's very good as it is now, the parametric eq is just a nice-to-have

EDIT:
You can also see in the data sheet that as expected band 1 (low) and band 5 (high) are shelf-EQ's, while the mid bands have bell characteristics.
Very interesting seems to be that for negative gain values the bandwidth of the EQ's is big times smaller than for positive gains, making negative gain settings more a cut for specific frequencies (the currently fixed center frequencies) and therefore not very usable.
The further i read the datasheet the more sure I am that filter bandwidths are not programmable.

I think there is a way, looks like voodoo sound has an interface for that, check the file /sys/class/misc/voodoo_sound/headphone_eq_values it contains 3 values for each band and some hex values:

Code:

1 A 0x0FE3
1 B 0x0403
1 PG 0x0074
2 A 0x1F03
2 B 0xF0F9
2 C 0x040A
2 PG 0x03DA
3 A 0x1ED2
3 B 0xF11A
3 C 0x040A
3 PG 0x045D
4 A 0x0E76
4 B 0xFCE4
4 C 0x040A
4 PG 0x330D
5 A 0xFC8F
5 B 0x0400
5 PG 0x323C

We just need to find out how this works and we can configure it like we do with all other values...

Which of the values do you change with your app at the moment?
This value is gain then.
Seems the shelf EQ's 1&5 have one parameter less.

EDIT: Gain value is 5 bits only according to data sheet, how do you handle this?
Or better question: how does voodoo handle this? Is the given 16 bit value scaled?

EDIT2: Would be nice to see the actual gain value (-12dB...0...12dB in 1 dB steps), maybe on the right side of the seekbar.
Also the current center frequencies would be nice to know for the users (1: 100Hz, 2: 300Hz, 3:875Hz, 4: 2.4kHz, 5: 6.9kHz) according to data sheet

Gains are separate files, headphone_b1_gain ...

After converting the hex values to decimal in excel i think that PG values are the center frequencies, most likely simply in hex.
I try to modify them manually and see what happens.

EDIT: Can't really access these files manually with root explorer... maybe you can try?

superkoal · Feb 12, 2013

I sent a message to supercurio (the dev of voodoo sound), he has always been very supportive, so maybe he finds a few minutes to help us out!

FadeFx · Feb 12, 2013

New version online, fixed a problem with set on boot and probably some other things.
