Ive noticed some distortion on almost all of my music on my 8125. I could never put my finger on exactly what it was so I figured it out today.
Using TCPMP I adjusted the equalizer so everything was at zero. Then went thru the range until I nailed down the distortion. It appears that in the 14khz and 16khz bands I get distortion.
Its really only noticable on songs with continuous highs (Im using radiohead to diagnose the problem). On songs that just have a quick cymbal taps and other short highs the problem isnt noticable.. but some songs its very noticable.
Ive found a short term solution just to turn down the 14khz and 16khz bands. Sure I lose a few highs (I cant hear 15khz+ anyway lol) but the reduced distortion is well worth it. The only downside is the next/previous track buttons dont work with TCPMP.
Any ideas on solutions?
Something is wrong with the audio playback using a headset with my wizard, I get a very strange sound distortion like radio interference with the audio. I have tried several headsets and reloaded the audio files. I have also tried the files and headsets with different devices and the problem is definitely in the wizard. The distortion is not very loud so I can't tell if it is present with the tiny external speaker or just over the headphone jack. Has anyone else experienced this? Any fixes? I have reloaded the device several times so it is definitely a hardware issue. Also it wasn't always this way so it is something that has developed over time.
Thanks,

Hi all,
I got my Hero on Monday and I'm blown away by this phone so far!
The only not-so-great aspect I have found is the music playback:
1) There is a small amount of background noise when playing music, which is noticeable
in a quiet environment during low-volume parts of tracks. I don't always listen to Metal on the subway, so this is kind of a problem.
2) Sometimes, when listening to consecutive tracks of an album, there is a stutter when a new track starts. Haven't found a way to reproduce this reliably yet.
I was expecting to be able to ditch my iPod for the Hero, but I'm a little hesitant now. Does anyone else experience these issues?
I have the same issue with the jumping at the beginning of a new track, haven't noticed the background noise though probably because I do listen to metal.
Maybe it has something to do with standard sd card or how the mp3 was created? I hope someone knows the answer.
Also:
Does anyone know if there is a graphic equaliser somewhere? Music seams to be too trebley (using Seinnhauser earphones), but I haven't been able to find anyway to adjust it
Forgot to mention: I used 192 kbit/s MP3s encoded by iTunes and portable AKG headphones. I'm going to try out the included earbuds when I get home, to see if they "equalize" anthing.
I'm listening to Rufus Wainwright's Hallejuah on my Hero now over a set of Sony MDR-NC22 Noise Cancelling Earphones (in-ear type) with the noise cancelling switched off. No background hiss. Could it be from your MP3?

That's possible of course, but I never noticed noise like this on my iPod. One other thing I'll try at home is listening to a WAV file and check for noise.
Send me the MP3 file and I'll load it up on my device now and let you know if I'm having any problems

Ok, I tried the included earbuds, and the noise is much less pronounced than with my AKG headphones, but still audible. It starts as soon as the playback begins and stops about 2 seconds after I pause the music player. (I guess this is when the audio hardware shuts down.)
MP3 and WAV exhibit the same noise, so it's not encoding artefacts.

Is it a buzzing noise?
I'd describe it more like a hissing sound.
Edit: I have attached a sample MP3 (hissingat5.mp3) in a ZIP file. I can clearly hear a hissing sound around 0:05 when the music gets quiet and I'm not using the included earphones. Anyone else? (I've checked the original CD with the same headphones, there's definitely no noise on the recording.)

My ipod touch does this sometimes. I have to reboot the ipod and its fine after. Maybe its because they are low on memory. Have you got lots of apps running? Try taskiller and try again?
I've found the music app struggles the most with low system resources and during the phones numerous "heavy lag" periods makes play back shutter or even stop altogether!
And god forbid you have more than five albums with bog standard 600x600 cover art... slow doesn't really describe it

Good idea, that might be a reason.
I think I'll be sticking to my iPod for now, though. While the stuttering problem is probably fixable in software, I'm not so sure about the audio quality.
my music also lags(espacially in sleep mode.. it's ridicoulis)... it's so annoying.. something needs to be done about this... I've tryed to memory cards and the music lags on both.. one is fast and one is slow..
I've found that if I play music through the phone itself or my headphones, there's no problem. If i connect it to my little 2.1 speakers, songs stutter, jump, restart, skip etc CONSTANTLY. Any ideas why this could happen? The speakers work fine with everything else, afaik. And the Hero works fine with other stuff... guesses?
I also have the slight hiss for a few seconds. Sound quality is pretty average, but i have my awesome samsung P3 for that
Im using a Philips SHB9000 stereobluetooth headset, theres no hiss in that, maybee its bound to wired only? thoe i have some stutter.. i use a Class 4 4GB Microsdcard.

Yeah, since you're not using the Hero's audio hardware at all, I wouldn't expect there to be any noise.
BTW, how much does the bluetooth headset drain the battery? I was thinking of using one to solve this problem.
Lack of gapless playback is also a bummer for me. I might be going back to my Zune.

Exactly the same as on my phone. I'm on my fifth Hero now and knew about the hiss already but this is the first to stutter. Exactly the same files, exactly the same memory card, exactly the same apps installed and running on the system.
No idea why one Hero has difficulty and others don't.
My Hero stutters even in the middle of songs on playback. I tried an alternate music player (nswPlayer) and it didn't help. I'm using mp3s but I think they're 320kbps. Maybe a re-encode would help?
Here's an odd one, and I was wondering if anyone else had experienced this;
The opening track on the Elixa Doolittle album is a song called 'Moneybox,. I have this as a 320kb MP3 file on my X10 and PC. I notice when I play this on the X10 there is a lot of distortion especially in the first 30 seconds or so, sounding kind of like a blown speaker, and mainly in the left channel. I have tried several media players and earphones but it is still there, yet I can play the same file on my PC using same earphones and it sounds fine.
I haven't noticed as yet any other tracks exibiting this problem, and I do listen to a lot of music.
So I was wondering,
a) is there a fault with my handset,
or
b) has the mastering engineer of this particular album cocked up slightly, as (and being in the business I know this next bit to be true) they are supposed to produce a finished product that sounds great on pretty much any playback media.
It's almost as if there is some sub bass stuff going on that the X10 amplifier stage just can't deal with.
distortion
it happens when mastering is too HOT i mean roughly >95dB and clipping occurs. Mp3gain the only solution http mp3gain.sourceforge.net it will not change the quality of a song -just its loudness (preamp). I can honestly recommend it --> all your mp3s and mp4s (AAC there is an option for that too) will have equal volume. just scan and fix Your whole collection (it may take some time). Some sh*tty mp3s are so loud that even at the lowest setting in a phone are too loud and distorted,
Cheers
Simon
thanks for the advice, so do you think maybe the x10 pre amp stage or D to A is more sensitive to this than say, my PC sound card (Tascam US-144)? Turning output volume down doesn't reduce the effect BTW.
tried it, reduced level but distortion still there - bizarre...
Ive downloaded a few from vodafone music store and theyre the same. Quality wise we have gone backwards! My nakamchi cassette deck wees all over mp3s
Sent from my X10i using XDA App
Nakamichi. .. now that's quality!
Amyway, I know we are only talking about one track but the fact that it sounds clean on anything other than my x10 is interesting. I want to find out if its a design issue or a fault with my handset.
Can u post it here so that we can check.

Yes, only the part where problem was discovered.

this is just plain odd...
I have just loaded the track into Cakewalk to clip 20 seconds off, then exported as an mp3 using LAME encoder. My plan was to put the clip on the phone, then record the headphone output so I could upload both a clean clip and a distorted clip for you to compare.
Thing is, the mp3 clip plays fine on the handset, yet it was taken from the troublesome file, which was originally a 320kbs file, and re encoded to 192kbs.
I wonder then if it is an issue with 320kbs mp3 playback?
I must stress that I did not alter levels at all during re encoding.
Odd.
Well, the obvious first question is: How are other 320kbs files? Also, have you tried a format other than MP3? Mediascape can handle AACs in the .m4a format... could be a corrupt file somehow.
It is noticed that while listening through headphones that the sound is being affected by some sort of 3D/spacial/EQ process that might give the impression of "punch" for movies but at the expense of phase-y sounding vocals and smeared high notes for music.
Yikes. Thst stuff is not good for music quality. No way to turn off? The settings options seems kind of scarce.
After playing around with various music players and headphones it seems that the audio is now OK.
Not sure what happened. It may have been a headphone jack issue. Audio sounds great now.
Oooops!
There is an issue with sound quality. Compared it to a Rockbox'ed Sandisk Clip Zip with a very wide stereo track 2-channel stereo track (fyi -- Brook Benton's "Kiddio" 1960). There is some EQ bast boost and high frequency crossfeed that narrows the stereo separation. I'm going to boot from CM and see if the problem persists.
For video I would not notice the issue, but could get to me listening to music with my Klipsch S4 buds.
Update:
It is not bad. Seems part of the issue is low gain which can be increased with Volume+ or other similar app function.
Volume+ did the trick for me. Jamming to some Coheed at the moment. Sounds as good as my other tablets now
The problem was never with volume -- I think stock has plenty of volume for driving Audio Technica ATH-900x. The problem is with some sort of audio processing that affects the soundstage and frequency response.
I am not hearing it using the Google player app. Gain is not the same as volume. Both need to correlate or weak quality.
SRS processing is used and applied at the headphone output. See HD+ file \system\etc\srs_processing.cfg
This is what I use, have my settings set to Jazz "my preference", audio sounds great, not talking about low resolution MP3's.

I understand the config issue, but I am not hearing it. I should hear the sound manipulation with cymbal decay as example, but not hearing it. Weird.
Playback in CM 10.1 has the correct stereo image.
so am I
