[Tutorial]Audiophile Sound Quality in your PDA Phone MUST READ FOR MUSIC LOVER!!!

Hi, i just wanna share a little for all of you in this community especially those who use Atom Life. This trick can be applied for other phone too. Feedback are always needed. So here's the Tips & Trick :
Music & PDA Let's mix it!
There's two audio output component in your PDA, headset jack and speaker. Most of all time to reach a good SQ (Sound Quality) many of PDA user apply different setting for each output. Example : if you use the earphone then u change the EQ, SRSWow setting even the player setting itself to reach the quality you want. But after u switch to speaker (in case your friend want to know what are you hear), the sound is disaster and you have to switch it again to match the quality for the speaker.
So how about if i can give you a little trick to set the optimum setting for both speaker and earphone? It would be great...
I have do some research and of course testing to find the perfect optimum set for both.
1st Rule in music : A good music need a good player to show it's potential sound. And what player do you use? WMP is bad and suck we all know that, so what the other choice that good? I recommended you to use Nitrogen check it here. Why? Coz it's deliver a superd audio quality and better than core player. It's only use minimum ram than core player (tested on mine running Nitrogen on standby use only bout 65% while Core suck 75%). There's plugin for FLAC playback (audio lover like it ). Also it's support skin too. Make your phone more music friendly. For qvga device you view here.

}
2nd Rule : You have a good music, and a good player. What's next? An optimized setting for your audio output both speaker/earphone. Where it can be done? Check out your equalizer panel (Atom life O2 Software). Disable the build in equalizer, turn it off. Now move to the WOW HD Settings (enable this). Set this :
SRS 3D Effect : 50%
SRS Center Effect : 80% (on earphone if you feel that it's not balanced you can adjust it. set it as you like 50% or more, coz everyone ear is different and unique)
SRS Focus Level : 80%
SRS Definition Level : 20%
SRS TruBass : 80%
On nitrogen set EQ to flat (or don't turn on).
This setting combined with nitrogen will give you a great audio quality gain. With large frequency range to hear more through speaker/earphone. And also a superb bass quality deep but not overpress other sound channel. Making your music more great (feel the difference test it with your favorite song).
3rd Rule and the important once if you use earphone : Buy yourself a good quality jack converter from 2,5 to 3,5mm.
So you can use a good quality earphone to listen your music.
Here's what i use MD E945 BY MDISK
Impedance : 32ohm
Speaker : 13,5mm
Sensitivity : 106db @ 1Khz
Frequency range : 10 - 25.000Hz
WHAT YOU HAVE TO WATCH WHEN SELECTING A EARPHONE IS THE CAPABILITY OF THIS PHONE TO DRIVE THE SIGNAL. (Example : you bought a high end set or earphone but it have a high impedance and therefor your phone cannot drive it signal coz there's not enought power. So it's useless.)
Another way to increase is to buy an small earphone amplifier for your phone (but it's not practical, so don't suggest it).
Also when you have a nice set of earphone, don't forget to burn in before to optimize the quality of the speaker. All About Burn in view here. And if you want to burn in your earphone download burn in wave here and view my burn in playlist.
That's all i can share, waiting for your feedback. Perhaps you can share your setting too here or audio player you use. Thanks.

Audio out

If i use the 3.5mm headphone breakout cable with headphones, i hear music fine, if i plug a 3.5mm lead that goes to my stereo, nothing is output, if i play with the 3.5mm jack, i can maybe hear music for a second before the music app closes and again no music is output except internal speaker.
Does anyone know the answer to this?

its something to do with the output resisitance. we need to change it. there was some development/research into this a while back.

The answers are a bit scattered across several threads, but if you have a look at Post #7 and onwards in this one is a good start. There are also some photos of made up leads showing how to address.
In essence Oly's comment is correct, but the nub of the issue comes down to the fact that the uUSB port is not just a hard-wired audio output in the manner of a traditional 3.5mm socket. The same contacts are used for multiple functions depending on the resistance presented to the sense contact. That causes the device to change mode and then channel data or audio or go into charging mode, etc.
I can't instantly give you all the links, but if you search on the TG forum for 'audio' and my username, you will find several further references. One in particular on Brighthand gives details about connecting an external hard drive successfully.
Hope that helps,

Kevin

Audio Output to amplifier
Here
http://forum.xda-developers.com/showthread.php?t=936562&highlight=audio+output
and here, as kevinpwhite say, was the first thread facing this problem
http://www.modaco.com/content/toshiba-tg01-tg01-modaco-com/298887/headphone-amplified-sound-output/
Below, my own experience "tuning" a couple of PHILIPS portable amplified speakers to use with TG01 soldering a couple of 470 Ohm resistors:
1)between input left cable and ground cable
2)between input right cable and ground cable as well.
This doesn't affect to the sound at all and you can use any other sound source without problems.

HI-RES AUDIO on Z3 via USB has vanished

So it seems Sony removed Hi-Res Audio from the Z3 when they changed Walkman to "music".
I have been using the XBA-Z5 earphones and MDR-Z7 headphones through the
PHA-3 Sony amp with Xperia Z3
and the sound with this set up, while not really mobile,
is beyond incredible.
BUT after lollipop the option to use the PHA-3 amp for hi res audio
through UBS is missing.
Here is the old settings page on z3...( sorry Japanese )
and the new one

Yup not there for some time now.
Sony is promoting their new HiRES player. So they removed it on Z3. They always do that. It's called marketing.

The option still exists in the latest "Music" app for Kit Kat. The reason why you don't see it in Lollipop is because Lollipop supports sound over usb natively. Kit Kat did not. It was a custom option that Sony added to our phone.
"Android now includes support for standard USB audio peripherals, allowing users to connect USB headsets, speakers, microphones, or other high performance digital peripherals. Android 5.0 also adds support for Opus audio codecs."
https://developer.android.com/about/versions/lollipop.html

Sorry if I bump an old thread but does the USB amplifier works natively like the previous poster said or they removed the functionality? I was thinking about buying one but I'm worried it might not work properly now that the option has vanished.

I would say the above reply is correct, this was simply blended into 5.0 and you no longer need to check the USB box,
it is automatic.
Still, I was inspired to buy a ZX2 walkman in fear we were losing the hi res audio and sadly now no going back, wow.
Now I get why the phone app was changed to "music".
Still, I'd say above issue and this thread issue has been resolved.
Hi Res Audio is still a part of Z3 ( though I noticed they dropped the Hi Res Audio logo when promoting the Z4 in Japan ?? )

Kind of off-topic but how is that ZX2? Worth the investment?

In my opinion absolutely without question, the sound when used with the correct headphones and amplifiers, and even without the amplifier, is beyond belief incredible. So I would say a very strong absolute yes.
I grabbed the xbaz5- in ears by Sony for when carrying this thing around outdoors, and that too is an incredible experience and also well worth what many are are going to be a ridiculous monetary investment.

While I'm perfectly content with my Z3 and ATH-IM03's, I can only wonder and dream what nearly $2k of portable sound equipment provides to the ears.
I imagine it's something like being cradled by a choir of singing angels in a cloud chapel.

Thanks for the information. I just removed the Music update and gone back to Walkman. Now i´m able to use my DAC again.

Android music player review - 1. general comparison

I used many Android music players as a music lover and tested them as a member of the team that made a music player app. So I decided to write detailed reviews about pros and cons of some music players in a serial form for one who is looking for a great app. This is the first part for introduction and I will handle the sound review in the next one. I tried to be as objective as I can, but a review is a subjective one after all and my thought could not be same with your opinion.
1. Poweramp

Poweramp is the most popular music player app. I bought it because it's highly recommended online. It provides lots of useful features and skins. You can hear the characteristic sound based on rich bass and use the sound effects like 10 band equalizer, tone, and limit. Reverb effect was also added in the recently released alpha version of Poweramp v3. I prefer its new UI of to the previous one. Although it doesn't leave nothing to be desired in the sound quality but is still a nice player for common music listeners.

2. Neutron
Neutron is an audiophiles' favorite among the Android music players. It supports most audio formats and offers a huge number of sound features. It allows users to adjust the sound in great detail but it's too complicated to use though its UI is much better that in the past. If you refer others' settings on the internet and adjust well you can enjoy good sound but it's so tough for me to make Neutron my main player. Anyway, it's ideal for one who need various sound options and 32, 64 audio processing.
*link: https://play.google.com/store/apps/details?id=com.neutroncode.mpeval
3. JetAudio
I often used its PC version so I also tried JetAudio app with anticipation. It provides a free basic version without a time limit while Poweramp and Neutron only provide time-limited trial versions. If you buy its pro version you can use 20 band equalizer instead 10 band and unlock the sound effects like AM3D and Bongiovi via in-app purchases. I heard its sound effects would enhance the sound quality and I bought the pro version and in-app products, but sadly, the result didn't satisfy me. I think its sound is worse than other players in this writing.
*link: https://play.google.com/store/apps/details?id=com.jetappfactory.jetaudio
4. Rocket Player
Rocket Player is another popular Android music player and provides a free version without a time limit like JetAudio. Paid version provides preamp, 10 band equalizer, replay gain, and etc. Its volume level is quite loud and sound is decent. But it has less extremely low frequency and too much mid. Another issue is that use of 5 band equalizer causes lower volume and worse sound quality. I'm not sure whether 10 band in paid version has the same problem or not because I hesitated to buy it. If you use paid app, please let me know how it is. Rocket Player is a good choice for one who wants a free and decent player yet.
*link: https://play.google.com/store/apps/details?id=com.jrtstudio.AnotherMusicPlayer
5. PlankTone Music Player
PlankTone Music Player is a newborn app made by our team. It's not as famous as other players but I think it's worth trying, especially in the sound quality. It provides a trial version and in-app purchase is needed after the trial period. You can hear a high quality and balanced sound without complicated settings. It also let you individually customize sound effects for each song. But it is at an early stage so it does not have features like tag editing or downloading album art and doesn’t support themes and skins, and doesn’t offer various widgets now.
*link: https://play.google.com/store/apps/details?id=com.chapter3.planktone
It’s a general review of music players and I will write a more detailed sound review next time. I will handle the sound characteristic, sound effects setting, test result with DAC, etc.

Audio Distortion on 2 channels - Phoenix Android Octocore PX5 - Where to look next?

So back in August I purchased the octocore unit, with Oreo, from Phoenix Android Radios for my 2018 Civic Si. Since then it's been hell trying to figure out the distortion from my Front Left and Rear Right speakers and why fading to Front Left causes extra distorted audio that plays from both Front Left and Rear Right speakers. Same goes if fading audio to Rear Right - extra distortion and also comes from Front Left. Fading to the Front Right or Rear Left sounds normal.
Issue:
Audio sounds distorted - especially in the upper hz ranges (none specific - but not apparent under 500hz). When I use the pre-installed Amp application and fade the audio to FL (Front Left) I also hear audio from the RR (Rear Right) - it is extremely distorted to the point of disgusting and vocals cannot be made out. If I fade to the FR or RL the audio plays only out those channels and sound quality is what I'd expect. It's important to mention that the distortion isn't as extreme when playing on all speakers - but noticeable enough to be annoying especially since I'm positioned closest to the FL. I can only listen to podcasts... playing music is just painful.
Original Theory:
I must have crossed wires somewhere. I tapped/soldered (w/ shrink) directly into the harness of the radio and sent the high-level output directly to my speakers, bypassing the factory amp as Phoenix instructed me. As a sanity test - I tested each speaker individually to check for phase issues. When using an alternate audio source (cheap Bluetooth amp) to send signal, the audio sounded great across all channels. I even intentionally crossed the FL & RR negative wires (maybe I'm colorblind and can't read the labels I put on the wires) and it sounded like what you'd expect... I've wired speakers before and not new to this at all. But I've made mistakes before. I had two friends confirm I'm not crazy here. :victory:
New Theory:
Maybe the radio's built-in amp is trash. So I dished out $140 and bought a 4-channel amp and hooked up directly to RCA outputs. After doing this - not only did I lose the Android sound effects (and other things), but the main distortion was still there. Using the Amp app and fading to either FL or RR would play the exact same distortion from both channels at once. Again, as a sanity check, I plugged my tone generator into each RCA on my new 4-channel amp. Each channel worked as expected. This confirms the wiring after my amp is good. And even if I managed to screw up 4 RCA plugs - it would just swap channels, not cross them. All RCA input/outputs are isolated to prevent touching each other.
Current Theory:
I'm getting some kind of interference, maybe, but it's only affecting two channels? Or there's probably a software/hardware issue. I used FooBar2000 music player to play music and set it to convert the music to mono - the distortion was gone! Then I used the same app to down-sample the songs to mono then up-sample back to stereo (redundant - extra CPU, etc.. I know) but this HELPED the distortion significantly. I can actually listen to a song stored on the unit/usb as long as using FooBar2000 to play it and not Bluetooth or any other apps on Android. This leads me to suspect the pre-installed Amp app is sending wrong signal to each channel or it's from the built-in amplifier.
Testing - Getting Scientific:
I decided I would do a test to see what kind of voltage I'm getting from the low-power output of the RCA and voltage I'm getting from the radio's high-power speaker line at various volume levels using the Amp fader to "all" channels and comparing those results to ones when fading the test-tone to the FL speaker only. For this test - I only used the FL and RR speaker and used a constant 1K tone. I noticed when checking voltages while fading to FL or RR that the voltage wasn't constant. It would move up and down by .01 to .02 volts. Testing while faded to all channels shows a very steady voltage. Here's the results:

If anyone can help me get to the bottom of this please! I've spent so many hours/days slaving away trying to make this work. I've re-wired everything 3 times because I kept thinking I must have made an issue somewhere as Phoenix Android Radios support team and engineers don't know what it issue is. Latest was telling me to check ground - which I grounded w/ short thick gauge copper cable (multi strand) direct to frame. Confirmed good ground w/ multimeter (was was original ground).
If someone would like a video to demonstrate this better please let me know and I'd be more than happy to record one right away!
