Pre-Amp development request (Universal) - Windows Mobile Development and Hacking General

One of the major problems with the Universal is its low audio output, not so much its playback of MP3, this can normally be sorted with a half decent set of headphones. But its output of system sounds, notifications and phone rings etc which when in a case or pocket are often drowned out by the everyday noise of life.
The hardware is clearly able to produce louder volumes, TCPMP and windows inbuilt media player clearly show this is possible.
So I`m calling on any programmers willing to give writing a system pre-amp module a bash to do so.
Don't have to be fancy, a simply sliding volume conntrol for pre-amp and maybe a test sound button.
I`m sure this would make a lot of UNI owner happy.

Speakers

Hey,
I have an exec and the speakers arent that loud, cant really hear it ringing is there a limit on the volume, like a restrcition and if so can it be removed?
Noticed the same thing very weak speakers/audio output. Tend to miss at lot of calls/txts when just out walking in town.
I think this could be done, maybe not via the reg. If you look at TCPMP there is a pre-amp option which does get the sound levels up (sadly only for whats playing within TCPMP), so the hardware can make more noise.
What we need is a goodly programmer to write a pre-amp program to catch all the phone (system) sounds amp them up and output to the speaker.
I can but dream !

this would be the same as pre-amping the ring-tone on your PC and transfer it to your phone. no need to do this "live" on the phone. tcpmp only maximizes the input-level of the audio, it does not make the speaker any louder really.

Music output Quality is Pathetic.. I stand corrected please.

Load Music, connect the earphone and the output sount quality is pathetic/worse even compare to the XDA ATOM/Exec or for that matter any other WM device I owned in past. On the other side the speaker output quality is still OK. The sound through the earphone ecos..sometimeit the voice goes low and instruments are high... normally this happens when you switch on the 3D surround on other devices like samsung Innov8. But the in X1 the quality is worse.. I even took it to the sony service they reloaded the ROM a fresh but the problems still remains. IS IT THE ACCEPTED SOUND QUALITY FROM X1. How about other owners .. do they get better sound output/quality through earphone. Is there anything I am doing wrong, Kindly suggest.
really? i find the music quality more than good enough. what headphones are you using?
The Headphone quality is f*cking good!!! I havn't heard this kinda bass on my I-Mate Jam or HTC TyTN II.
One thing is correct, the quality of the original earpieces is bad.
I got ones from creative. The one that go into you're ear.
The speaker quality..... Don't talk about it. Hate it
I'm using Sennheiser CX400 earphones and the sound quality is actually better than my iPod 5g.

The headphones supplied with this phone are suprisingly high quality ones. I have my own Phillips branded ones however.
Aside from the headphones, I think you issue is with the software you use. I found that WMPlayer is pretty crap when it comes to playing my favourite tracks. I use PocketPlayer and also Pocket Music, which have some very good equaliser functions. They make a big difference.
I also find the sound quality f*cking good!!
I expected the worse because it's a WM device, but it exceeded my expectations. Also using Creative ear-ins (EP-630)
I think there is a bug in the Sony Media Player software that can result in a seemingly poor quality sound output.
I've found that when opening the media player for the first time and playing a track the soundstage of the music sounds like its collapsed (lacking any high end or openess in the stereo image). If you then tap pause and then play again all of a sudden the soundstage opens out and the sound quality is very good.
Since I've turned on the "clicking" noise for screen taps, the above bug doesn't occur so often.
However, if I receive a call whilst listening to music after subsequently hanging up the bug re-appears.
Anyone else getting this?

I have this too, but I don't think the bug is mediapanel related only.
I get this when I use S2P, Wmplayer and the media panel.
Sounds almost like flat mono before I tap pause and then play again..
I don't see this as a huge bug, but it can get annoying.
It depends on the mood I'm in..
can anyone compare the speakerphone to a nokia n73 or n70?
It's definitely weaker than the N73 one.
so much so its sickening or just a tiny bit? how bad are we talking about here :S?
I was expecting this thread to be about the poor speakerphone quality.... which it is. I know of no WM phone with a good speakerphone so I wasn't expecting it to be as good as my N95's. However, music through headphone jack is as good, or perhaps even better than my N95 (not as much background hiss as the N95). I use Shure SE430's (pretty expensive earphones) and I find the music playback to be quite good. I even hook the X1 up to my Logitech Z5500 speakers through the Line-in jack and I can pretty much DJ a party with the phone and it sounds as good as if the songs were being played off my computer. (This is all through the SE Multimedia Panel btw. I get similar results with CorePlayer or Windows Media Player).
The only problem I have with the media panel is I can't receive calls with it open. That may or may not be a plus/minus to some people, but I guess it's ok. When people call me, it goes straight to voicemail. The only way I can receive calls with music playing is to go back to the today screen (with the music still going), which works out ok too, since I hold the end key to lock the phone, which brings it back to the Today screen before locking.
worst audio player?? are you kidding?
sorry, but thats definitly NOT TRUE.
***************************
the x1 has got the best and most powerfull audio out, i`ve tested. (but not compared with n70/73)
i wrote it few days ago in the accessoires threat.
i use the Ultimate Ears Triple.fi 10 Pro Inear
with 3 drivers/speakers per earpiece. (like a 3 way oldschool musik speaker)
i`ve tested my ue10pro headsets with a lot of other mp3 players and mobile phones.
but the X1 is the first player, who can unleash the power to drive the UE 10 pro to there limit....
only my sondcard a creative x-fi has got enough power to blast your ears/tympanic membrane....
the base is unbeleavable! the headset can go down to 10hz. and the high tones are crisp, sharp, clear. but a little
to soft from the middle to the highest frequency. but this could be fixed with the equalizer/audio booster.
if you set the first base frequency to +12 and the second slider to -10, you can formerly 'feel' the extreme deep bases.
you cant beleave, that you are not in a club!
don`t use the x1+ue10 for longer time on maximum power. thats very risky for your ears. trust me.
the only thing is, you have to use coreplayer and calibrate the equalizer.
or use a new custom rom (touch it hd) with integrated audio booster.
holy ****, that rulez!!
Ultimate Ears Triple.fi 10 Pro Inear (~300$-400$)
http://www.ultimateears.com/_ultimat...escription.php
these devices with othoplastic, spezially for your ears. and a laser burns your name into the headsets.
if you have 900$ bucks into your pocket, take a look at that:
http://www.ultimateears.com/_ultimat...escription.php
or 1150$? with 4 audio drivers/speaker per ear!!
http://www.ultimateears.com/_ultimat...escription.php
this is the last headset you buy! the cables are replaceble with translucent cables and iphone button.
no more broken headset cables/wires.
my advice, use coreplayer. DONT adjust the equalizer/tone faders more then 12 db.
you will be surprised.
(core is able to adjust more than 12db/slider. more then 12db will bring disharmonies and ugly subtones and crickeling)
(the audio booster could only adjust 6 db. thats not enough for xtreme bases.
but dont use in coreplayer the 2 lowest faders both to +12. thats to much base and
the headsets and the power amp will be very unprecise and roar/rumble and you run into danger to burn the headset
for good kickbase decrase the lowest fader to -3 and the second fader to +12, the 3th to +6. increase the high tones 1-4 db.
for good ultra deep base drums, set the lowest frequenzy +9 or +12, and the second one to -2, the third 0 db.
i have a ultimate ear fi 5 pro headphones with two driver lower is range then DOMin8or tri fi 10 pro. i get quite good results but not on the default player. I only use touch flo 3d in -built music player with audio booster, if you know how to set it , i guarantee you get better sound then walkman phone. i prefer bass and vocal no to be so dull. get the touch flo 3d music player set it to rock mode first then try to made this mode to v shape by just shifting the first two bar to be same as the last two bar, trust me even if you are using your default headphones, you will notice the difference

speaker phone n95 8gb i think is the best
try this setting on audio booster
possibly, but i will it verify by my own. for me, this is the best combo i`ve tested. and ths x1 has got exactly that power, i`ve searched for. more power will destruct my/your ears
i like this unhealthy power of X1. and at 90% power, the sound is very precise and defined.
and 90% is my personal max. and i like it loud. but 100% ? not with me. *G
audio booster has got other cross over frequencies. so my advice/hint could not used with audio booster. audio booster has a range of +-6 db. thats not as good as cores +-12db(possible +-18, but most time useless. only for spezial noise filtering. for example in microphone recordings)
the most players output power broken down, if i increased the base and at high volume.
with other players, you can formaly feel the missing amp power. (ipod nano iv suuuxxxxxx,cheap no name mp3 player,orbit,diamond,nokia 6233, creative zen v plus. but zen v was the best.(not the best menu, but good sound quali)
but now the x1 is my favorit device)
imho the x1 has got a good power amp.
im not sure will it fit everyone style but after some tunning i think this settings best for me to go for on default earphones, i have been looking for post how to optimized sound quality, here is one, hopefully more will share there experience, i bought the x1 because of the 3.5mm connector if x1 doesnt has it i wont even look up to x1!

SGS Audio quality

Sorry guys if this is a duplicate but could not fine anything about audio quality.
Iam gonna buy this awesome device but just curious to know from u guys the audio quality for music from headphones (stock or other)
Also i have heard that the loud speaker is quite low. Now how weak would that be. Will it be not able to wake me up when the alarm rings??
Last question irrelevant to the thread title. My ISP in India is Sify. Now they have rpm and non-rpm (sh) based linux dialer. Will any of these work. There is also a free java based dailer with .jar extension where in i pass info like
sify.jar -u xxxxx -p xxxxxx from a batch file in windows.
. which would be the best java emulator to use in Andriod and how? Guys iam new to andriod. Thanks in advance.
actually the loudspeaker is quite load.. louder than my nexus one.. and with audiobooks and music you can get distortion..
plenty loud enough for ringtones etc.
Stunning!
Although I did have a 3rd party headphone buzzing problem that's gone away now......very strange.
The audio quality is absolutly amazing in my opinion. The headphones are very good and i also like the 5.1 option the musicplayer offers. (Sounds like sitting in the middle of the stage)
Via headphones the SQ is indeed excellent, check GSMarena's review - they use objective measures of SQ and the Galaxy S is essentially perfect.
Loudspeaker is tons better than HTCs offerings, I find it outputs quite a nice sound, definitely loud enough for alert/calls/alarms.
Thanks a lot to all of you who took time to answer it.
I have to agree. Speakers are awesome. Also, the amount of native audio codec that the phone supports is nothing short of amazing.
Samsung incorporated their mDNSe (mobile Digital Natural Sound engine) chip inside this phone (its the same audio decoding chip used in their home theater and HD LCD TV's except its a mobile version). It supports 5.1 SRS sound too.

help finding the best equalizer

hi everyone
i have just recently bought this app and cant believe i had not found it any earlier!
it has the best user experience a music player could give to you
i have been scouring the web for the different equalizer settings hoping i would find one that suits me best but so far no luck!
when ever i try a equalizer its either too bassy or the treble is not right then i hear the crackling sound! (on over ear headphones)
on the stock player i fared quite well with a equalizer but when i tried copying it on the poweramp equalizer it was over empowering
i listen to alot of hip hop, r&b, uk grime, bass driven tracks
i listen for bass and lyrics so how would i go about adjusting my equalizer to meet my requirements?
what is you equalizer like?
kind regards
eventually you will end up turning the equaliser off and getting a good set of headphones - you might hate the concept now - but if you want clear music with bass that doesnt distort then a flat eq is "best" for that. if you want to fiddle with an equaliser - dont make it go above 0 - always start from 0 and cut the sound away to get the sound eq curve you want - adding sound by increasing an eq curve above 0 causes distortion.
look up "mixget" and the instructions on how to use it - you can add volume with this - but its unlimited - you could damage your hearing BADLY with this program - do NOT set it to full and then plug in your ears and hit play - it could damage your hearing with the volume.... (and blow up your house and rape your dog and steal your car etc etc etc etc etc) seriously - this program can cause hearing DAMAGE - it unlocks the volume limiter on the internal headphone amp and can blow your ears out of your head.... take care with this one - but when its setup.
also look up "voodoo sound" by supercurio - mixget is based off his work
you will end up being very happy with lots of bass on your headphones from the galaxy phone - its a very high quality sound system
have fun and do lots of research
and dont listen to mp3's get flac files - if you want to know why - get your favorite track as an mp3 - then get it as a flac - tell me afterwards what you think of the flac bass response compared to the mp3 response
i am wiping my mp3 collection and replacing it with flac as i can find the tracks takes up more space but its worth it
the best thing you can do for listening to music tho
find a quiet place with no background noise..... its amazing how much sound you miss due to the quietest background noise.
i loves my sgs and my grado headphones

A7 Dolby Atmos Speakers Hiss at Low Volume Only

First I need to add that I find the so much advertised two DACs of the Axon very highly exaggerated in terms of power. They are just too weak, even compared to my previous Note 3, both on headphones and speakers.
Second, they seem to not be able to be effectively used on almost any app since 98% of apps do not utilise them by default and one cannot change it.
If you tweak Dolby Atmos a bit you can get it to amplify the general audio output, both on speakers and headphones, and this is why I use it predominantly. I am on the B09 update on A2017G and it is still very buggy. No matter what setting I choose, i.e. Music, Voice, Game, Custom, when I leave the Dolby Atmos screen it drops sound for a second and always resets to Movie, no matter what. Also the sound regularly interrupts, especially when unlocking screen or doing things in the background, or just on its own.
What annoys me most however from when I bought the phone is that at very low or low volume (only on speakers), when there is speach or the music starts, there is some kind of hissing, ss/sh-ing sound corresponding to the words said or the tiny beats of the music played. It's like a background noise added on purpose simultaneously with special, mostly high frequencies, i.e. words, tiny/starting percussions or similar, no matter the Dolby Atmos setting. This noise stays apparently at all times, it just is not heard when more, mostly low and middle frequencies get in. This "noise" is not available when no Dolby Atmos is used, however the volume then drops by a few levels down. Good or bad, Atmos also adds some spatial effect to the sound, which is why I like it for...
Does anyone of you, an A2017G or A2017U user, observe similar behaviour on your device? Is Dolby Atmos working better for you, i.e. unconditionally steady settings, no low volume added speakers noise, no sound interruptions?
I also noticed browsers do not get use of the DACs/Dolby Atmos, i.e. YouTube, online videos, many video players. My favourite before Aimp was unable to do so also so I had to transfer to Jet Audio and PlayerPro, both of which can work with the Dolby.
Why did ZTE add (two) DACs when they couldn't be used by 95% of the apps and games by default and even manually, also there seems to be no gain in output at all? Was this the case with the Lenovo Phab2 Pro's Dolby Atmos? For the "regulated hiss" (not present on headphones at all) I cannot currently watch any movies on the phone with Dolby Atmos enabled, unless at very high speakers volume. It hisses so badly every time a word is pronounced or some subtle 'invisible' sound plays. The same is with playing music...
I dont use Dolby when I listen to music - it makes everything so much worse and much quieter. Listening to flacs on stock music player with Super HiFi on. No hisses on low or high sound levels. Silence is silent. as for speakers - no hiss also.
ZTE did not add 2 DACs for music, 1 is for music other one is for audio recording which is records at 128kbps. and quality.. I dunno it's quite clear, I had recorded a room full of people, with two girls singing and some people chatting in backgroud and I can hear everything. but sound itself if on the lower end, girls vocals are lower than they are, everything seems shifted to lower sound spectrum.
Tooks some time and checked spectrum of that sound file 50-2000Hz. everything over 2kHz is just a noise.
and a little edit: it records nothing less than 50Hz - total silence there.
The stock player is OK but it's lacking on features, also not sure if it can play video.
I have noticed the low volume speakers "noise" with Dolby on when watching movies using almost any player - VLC, BS, MX and more. If I go above 30-40% volume it seems to disappear, but more like you don't hear it and it stays. I say "noise" but it is like a hissing/ss-ing sound added to sole frequences only, i.e. speech only or single instruments. When more frequencies get in, you don't hear it. Weird these don't exist at all with the Snapdragon amplifier, i.e. when Dolby is off.
https://community.zteusa.com/thread/12853, here is a similar thread in the ZTE USA community. I believe it has something to do with the Axon's own amp or its software and happens at low volume only. There was a thread in Reddit exactly about what I am reporting but I can't find it now.
If you go to your phone's Music\Settings\Dolby Atmos app, then move all sliders up you will notice that it significantly increases the overall volume when Dolby is on. So it's not low, if you change it, it boosts up the volume by at least 30%. On another note, the Axon's mic recording quality is quite poor/muffled, even compared to the old Note 3, hopefully they will improve it at least a bit by some future update.
I bought the A7 exclusively for its audio capabilities so am disappointed that I have to report insufficiencies in this exact area.
Does your Dolby Atmos set itself to Movie only if you exit the Music app? Are there any drops in sound when it's on and you do something in the background?
There are two DACs. "AKM AK4961 DSP CODEC, which can be considered the primary chipset for Hi-Fi audio playback and recording. The AKM AK4490EN DAC is an independent Hi-Fi audio sampler". So AK4961 works in standard mode and AK4490EN in Super mode. ADC is only in AK4961.
You can consider rooting your device and install ViperFX or the whole A.R.I.S.E. sound system. That will solve all the problems with sound output. However the sound recording filtering is surprising, leaving only the vocal spectrum is not normal. There should be a setting somewhere.
I have the Chinese A2017 model running Oreo & have just noticed this hissing sound which can be heard at lower volumes when I keep speakers close to my ear. I don't hear any hissing sound using headphones. I wonder if it's always been there or it's a hardware/software issue. I'm probably gonna hard reset the phone to see if it goes away. Anyone could fix it?
