My current Headphone amplifier setting is at -3 dB
And Volume limit is 5 dB
Is higher the number, the louder (in this case positive number) or lower the number (negative number)?
Thanks!
The measured volume (note measured, not perceived) doubles every ~3dB, so -3dB means about half of the volume at 0dB. Positive number means amplification, negative means attenuation.

I have an LG Optimus 7 and there is no speaker other than the earpiece. For certain types of sounds this is really quiet.
Whilst I'm not expecting high volume levels, a bit more would be good.
Are there any known registry edits to increase the system volume gain? I have seen registry tweaks for "increasing volume" but these only change the scale - the upper limit is the same.
This used to be easy enough under WinMo but can't find out how to do it on WP.
I'm on Kangy8 and I don't know if this issue is related to all ICS roms.
So when I adjust the media volume while listening to music I basically get this more or less:
- |..|..|..|..|..|..|......|.........| +
where some of the steps seem to be mapped to more than one volume level.
What the ... I don't even get it.
I want something like this:
- |..|..|..|..|..|..|..|..|..|..|..| +
I also don't understand the Voodoo Control Plus audio settings.
Current amplifier is a negative number. Why? So what I understand is, that it's amplifying the current volume?
I saw that CodenameAndroid comes with a 30 step volume addon but as far as I know this will conflict with voodoo sound.
I don't have that volume issue in the stock ROM on my i9023, possibly a kangy bug.
The amplifier level is simple and useful once you understand it. I'll give you some background first and some general numbers.
dB (decibel) is a unit, in an audio sense, which measures the pressure of sound waves. It is a logarithmic scale and requires a reference level to compare to. Basics with audio decibel values:
1dB : Threshold of noticing a volume change
3dB : A little louder
6dB : Double the sound pressure
10dB : We perceive sound approximately twice as loud
Now that's out of the way; the analog control tells the amplifier inside the phone how much it should amplify the sound. Using 0dB as a reference, which is generally the loudest it goes safely, how much less (in dB) would you like it to amplify. If you want it to halve the perceived volume, you'll drop it down to -10dB (effectively half as loud as full blast). The reason why you would want to do this is generally if there is excessive noise generated by the amp, lowering the amplifying power and raising the software volume will give you the same volume and power, but lower additional noise as the amp is working below it's limit. Higher quality DACs of course can reach their max amp capabilities and add no noticeable noise to the earphones/speakers, of course.
Hope that made sense
Have you tried the stock EQ on the Galaxy S4? I was messing with it earlier and man that thing is completely botched.
Basically, when you raise one of the frequencies on a legit equalizer, only that frequency gets enhanced and all the others remain unchanged.
In the Samsung EQ when you raise one frequency, that frequency doesn't actually change at all, the ones that change are all the others, which get LOWERED! Isn't this some bull****?
You can test this, and see that I'm right, if you raise all frequencies to the max, the sound will be identical to when all the frequencies are set at 0 (middle position). Another test you can do is raise any single frequency to the max, listen to the music for a bit, and then lower every frequency to the minumum and leave the frequency you raised before to default 0 position, the sound will be identical.
Long story short, this EQ can't raise any frequency even though the slider says +10dB - 0 - -10dB, all it can do is lower every other frequency so the one you raised is N dB higher than the others.

Would you able to list the model code of S4 you're using? I9500 or others?
Generally speaking, EQ is not a volume control.
With originally reserved gain, EQ can rise volume for selected frequencies which is the case for most home cinemas. For limited resources of phone, it's unpraxtical to reserve gain, so volume of zero is actually maximum possible volume. Rising volume over this point will produce distortion (or will produce sound louder than allowed by some countries). That's why this EQ lowering volume of non-selected bands. EQ is doing what is supposed to do - sound equalization. What it can't do - is to rise selected band above 0 (which is what you're expecting).

Hi all,
Would it be possible to separate the low and high tones, so the low tones are played through the one speaker and the high tones through the other?
I know the maximum volume may be a little bit lower when that's done, but it shouldn't make a huge difference either. 2 speakers doesn't mean the maximum volume doubles, in fact, it doesn't even raise that much.
Also, I don't know for the lower tones, but the speaker that plays the high tones could probably be pushed a bit loader since the driver doesn't come out that far. That way the total volume could maybe almost be as it is now.
After all this said/asked, THE POTENTIAL BENEFITS OF SEPARATING THE SPEAKERS.
When the speakers play the whole frequency of the sound, it may reduce bass or sound less "clear". This comes because the driver has to "trill" fast for the high tones and slow for the low tones at the same time. If we can separate the speakers so one speaker plays only the low and the other only the high frequencies, each speaker would have a smaller frequency range to play. This could give deeper basses and clear sounds.
What do you guys think about this?
Same as for V10 as well. A little tricky to Extender to stay indoors. I apologize if you've had this board, but I have not found, but the root method.
But you do not need root and do not lose your warranty. ( In addition, I have me a H990Ds.
What I can not even root. )
Virtually fooled the amplifier. With the headphones less than 50 ohms, a much stronger, more dynamic are all about.
As if bound in headphone amplifier. 3 positions
1. normal audio headphones under 50 ohms
2.only extender= aux (+ 25% power)
3.Extender and adapter 75 ohms = high gain (50-600 ohms) (+50 % !! power ) In this position it will be as strong as FiioX7.
the maximum amplifier module)
Aux mode :
1. If you only extender on the phone. Aux position will be.
Then, when we put on the headphones (below 50 Ohms), the Extender. It remains aux position to get more reinforcements. Approx. + 25%.
2 . if you have a headset which is remote.
even if the play / up or down/ play buttons to keep. about 2-3 sec.(Even before the insertion press and hold)
It provides about 25% + gain. (( Thanks for the idea: Ninjafrog84 ))
High Gain mode (two adapter required)
Connected together( extender+75 ohm adaptor)than to be inserted into the phone . (The phone will be HighGain position), then pull out the impedance adaptors increased. The extender will remain. (The phone still remains high position), this is the trick. !! and then you can plug in headphones to less than 50 ohms on the Extender.
And we enjoy .. High Gain, but be careful in your ears.
((( Over 50 ohms headphones will be automatically high position, there should not be any magic. ))
two adapters to be added.

Nota Bene : (( The High Gain the advantage of a stronger voice for: LG, according to all four DAC is activated.
If High Res plays music from the DAC. ,,Or,,
Also, if a high-impedance device is connected to the phone.
Nevertheless, not every player can send the output of high-quality music ..
But the noise 4 DAC lower , however, a great advantage.
In case of lower-quality music, and either normal (below 50ohm) headphones. Only one DAC operates.
(Hence the noise cancellation is less)
Because of the efficiency of batteries.))
That is why I, and hear it as well.
Not only is this strong in High Gain.
It's cleaner and nicer. (Be it a placebo?) But to hear the difference.
looks very interesting, thanks
anyone who has already tried this??
If you have headphones with volume control, try holding play and/or a volume when you plug in your headphones and holding it for a few seconds as the DAC boots. I had success getting my V20 to output to my cans in AUX mode. It's louder than standard, but I haven't seen or heard the think in high impedance mode, so I cannot compare.
It really works. will aux mode
a good idea if you have a headset which is remote.
even if the play / up or down/ play buttons to keep. about 2-3 sec.(Even before the insertion press and hold)
It provides about 25% + gain. (In the high gain mode to normal mode power 50-75% +)
If you are not the headphones with remote control.
You can first place a pre-extender jack plugged into the phone, and then plug in the headphone to the extender. Aux position.
I got the 75ohm adapter, the aux extension cable but even then i get the regular aux mode only on my phone. The aux is connected to the car, should that make a difference?

Pretty awesome trick! My HF5s just have a mic button. Holding that down when plugging in tricks DAC into AUX mode.
Never thought to do that with all my time with both V10 and V20...
On my V10 I used to use the Alsa mixer app from play store. It does require root, but you could target the ESS DAC and change the value from 0 up to 72, where 0 was high impedence mode.

Thanks. For people connecting-disconnecting often, it's maybe a better idea to use a cable extension (instead of the L shape adapter from first link above) + (same) 75ohm impedance adapter, so that you do not put excessive force on the smartphone headphone jack.
