Bad mp3 sound quality through usb cable

Hi,
so i got my diamond a week ago, and bought HTC usb-jack cable to plug my mobile on different hifi system to listen to my mp3
- sound sucks
(even i use core player, media player....)
When i switch on radio, quality is normal (good i mean)
And when i switch on my bluetooth headset, quality is also super (mp3, radio, ....)
Does anyone can tell me if it's normal or no, and how can i really improve the mp3 quality making it -normal- using usb cable !!!???
Thanks... A LOT

ahhh, youve used the audio booster havnt you? it has issues with unplugging headsets at the wrong moment and leaves you with permanant bad sound!
this thread will sort it out and get perfect sound quality back

MP3 sounds so great now on my diamond, using usb cable

R3A Media Panel's Radio Program question: what is Stereo RDS TA AF?

I just installed the new mxp panel... I have no idea what these options are:
Stereo on/off
RDS on/off
TA on/off
AF on/off
can someone explain what each mean and stand for and do?

Hi,
Stereo on/off => ?
RDS on/off => Radio Data System (display Station Information's)
TA on/off => Traffic Assistent (the radio switches to other
station, when there comes traffic information)
AF on/off => alternative Frequency (the radio can switch to an other
frequenz, when this signal is stronger)
hope this helps

Hello. How can I get this radio ?
Is it compatible with itje's Touch-IT 6.5/Manila image ?
Many thanks
S

As the thread title states, this is the radio in the R3A Media Panel.
You can find it in various places. I got it from here :

This is one chef that has a really cool ROM (because its fast) in my opinion and he has included some packs that contain various apps.
Download the Panels Pack then install MXP_MR2_R27_35200_signed.cab
The radio should be compatible with that image.

sterio or mono
Sterio on/off
Sterio is like surround sound and gives that 3d sound feel, more crisp and better sound quality
Mono is a dull sound not crisp but cuts out a lot of hiss and background noise you may get from radio transmisions
i never use mono that sound quality is terrible just like listening to am radio but if its a talking radio show with less music then mono is ideal for you.

Stereo refers to dual channel sound and Mono just to single channel sound.
In general...mono sound can be equally crisp as stereo sound. The "crispness" of a sound has nothing to do with the fact that the sound is stereo or not. It depends on bitrate, and other factors. Not to mention that in this example : 96kbit stereo mp3 and a 256kbit mono mp3... the mono mp3 will sound a lot better... Anyway back to radios >
"If your radio hisses on stereo but not on mono it could be because it is receiving a weak signal. This happens because radio receivers need a stronger signal to decode the stereo component of a signal than for the mono component. A weak signal can be caused if you are too far from a transmitter, or by large buildings or hills blocking the signal path."
(http://www.abc.net.au/reception/radio/common.htm)
If you listen to your radio thru the phone's loudspeaker, you might as well use mono. It will sound better than stereo in a weak signal area, and even if you have a strong signal...you won't be able to notice the difference since you have only one speaker

Jees
Someone has a stick up there crack
Just trying to be helpfull, its not my fault u need to take out ur anger on a public forum.
MY apolologies for not giving the exact, specific terms you could have just corrected me rather than offending.
Well im sorry poetryrocksalot for misleading you and causing you misery on this as my explination was totally out of my ass

Myea...I guess I owe you an apology as well.
Tense week for me up until now.
I didn't mean to be rude...

Yeah but when i listen through me headphones, I still cant determine the difference between stereo on or off. That was I expected to hear, but I couldn't spot a difference. Perhaps software is conflicting with the stereo function.
I also notice that installing the new R3A Media Panel disables my old standalone Radio Panel? How about you guys? Do you have software conflicts with the radio and media panel?

this probably also depends on your radio station as well. in most of the songs u cant hear much diffenernce at all in stero or mono.
all i can tell u ... its working for me

Okay you guys, I got some news:
1) If stereo mode is on, then you will hear tremendous static when listening via Xperia's speakerphone.
2) If stereo mode is off, then you will hear crystal clear music from the radio. Wow!!!
3) I have not tested how stereo affects the headphone sound quality.
4) I suggest turning TA (Traffic Assistant) and AF (Alternate Frequency) off. This is because 5 minutes ago I was listening to 102.7 and then it switched to 103 for no reason. It's more annoying then it is helpful.
5) I love the RDS feature of Radio, I can finally know what song is played on the radio.

1&2...I hear normal quality music with either settings....Maybe it's just your radio station?
4 ... Traffic Announcement can be quite annoying sometimes, but it can inform you of potential accidents, road condition etc. And AF is only helpful if the radio station provides the AF information (some stations don't)
5 ... Quite a cool feature, too bad not all of the radio stations (at least here) take advantage of it. Some just display the name of the radio station and that's all.

For 1 and 2... try extending your earphones as far up towards the windows as possible, make sure you get the best reception. Then switch to mono and stereo and you will notice the difference.

[Q] Bluetooth Audio Streaming A2DP Poor Quality

Hi Folks!
Recently got a bluetooth FM transmitter so i can go hands free in the car and use phones music player too
However the audio is very heavily compressed when using A2DP - no bass and the top end frequencies turn to mush - ie not good enough to use
Checked all eq settings and different FM frequencies, no difference
plugged the analogue audio cable direct from the phone to the bluetooth FM transmitter and immediately got perfect sound again
I dont see many poeple talking about this on this forum or many answers but the closest seems to be windows phones can access and modify registry settings to check and increase the bitrate
My current thinking is the bitrate (or bitpool) over bluetooth A2DP is set too low, or when the phone and FM transmitter pair the phone selects a bitrate that's too low for quality audio (but ok for calls)
My question is does anyone know how modify the bitpool settings on the Galaxy S please?
I am going to get a custom ROM and will very happy when the phone is really mine so if that's what it takes I'm up for it
Many many thanks!

2.1.1 Eclair on 3 mobile network in the UK
Nexus Drive Transmit Pro (Bluetooth FM transmitter music and hands free car kit)

I have the Galaxy S on 3 UK since August. I use the bluetooth to transmit sound to my Samsung surround sound system (as I don't own a stereo). I don't notice significant quality issues doing this. Are you sure both your devices are supporting A2DP. Not all A2DP devices talking nicely with each other, so you may be failing back to the normal Bluetooth frequencies which are more focus of the vocal range. I'm looking a car stereo's right now that support A2DP so I can stream my audio from my phone straight to my stereo, my phone is becoming the centre of my entertainment!!
I'm running Doc's ROM on my phone, can't recommend moving to his Froyo ROM's and an enhanced kernel enough, my phone is working so much better with his ROM, but there are lots out there to choose from.

I am using A2DP in my car too and I find the sound quality being very good.
The thing is, the default Android audio player (Music Player) is pretty poor and often it lags for me.
Since I moved to MiuiMusic (Search here) all those lags are gone and it works perfectly and smoothly in my car.
Now, as pointed already to you, all BT devices do not communicate flawlessly between each other sometimes...

works great for me, streaming from the SGS to the car CZ 509 deck
i don't even carry CDs in my car anymore
even the lovely sub base sound comes through clearly.
nothing better like a Sonic Massage meanwhile you are driving

I wanted to create a new thread on this, but then I've seen this one. Is there no one with a solution except flashing cyanogen?

It could be a setting on your bluetooth receiver.
For example, I've got a pair of Sony DR-BT21G bt stereo headphones. When you hold a special button combination, it switches it from "high quality" to "any quality", and will just select whatever bitrate it thinks is best, usually, something that sounds about half as good.
Try looking in your manual for troubleshooting and see if there are any settings that you can change on the receiver itself?

Hmm, i using Sony MW600 BT headphones. I've checked the manual, but there's nothing about quality :/
But i dont think that's the problem anyway, as i tried Cyanogenmod and it got perfect quality then. But otherwise cyanogen is quite useless for me on my Galaxy S, its just too buggy. There must be someone who can change the bitpool quality on the stock gingerbread to the highest possible...

Exact same issue for me (as described by DJ LIBRE), I have a Belkin Wireless Bluetooth Music Receiver and the sound quality is horid... it's got nothing on AirPlay which I think is still kind of average quality!
I also wonder if there is a highbitrate setting that can be adjusted?
Running CyanogenMod Nightly #130 on SGS.
After getting used to listening to 24/96 FLAC's with the Voodoo Sound mod enabled with a custom built headphone amp and semi decent can's all I can say is BT Audio is a waste of time!

Has anyone noticed whether the music player was set to 5.1 surround mode? Had a similar issue where turning off the 5.1 fixed the sound streaming...

[Q] Radio fm without stereo sound

Hi all, I bought a xperia T few days ago, but I find a problem in the fm radio. When I'm listening to a broadcast station with a good quality (the quality of the station isn't the problem) I don't notice stereo sound, It's always in mono (even though in the screen appears "stereo"). I try to force mono mode in the options menu (of the radio fm app) and I don't see any diference when stereo mode is activated when not.
Does anyone have this problem? I need to know if It's a generalized problem in xperia t mobile phones or I have to return my phone.
If someone wants to check this question, he has only to force the mono mode (in the menu) when is listening a good quality station (in which appears "stereo" in the screen of the radio app) and note the difference, I didn't detect any change but I should.
I've Jelly Bean actualization.
Thank you in advance.

[Q] Audio and video out of synch when using Bluetooth - any suggestions?

Hello all.
I'm having problems with Bluetooth on my One. The device that I'm trying to use with it is called a Siemens MiniTek. (It's actually a hearing-aid accessory. You clip to the front of your shirt - it looks a bit like an MP3 player - and it plus my hearing aids together then function like a Bluetooth headset. So, when making a call, the sound is sent wirelessly to the hearing aids, and the device itself has a microphone on it.)
Making a call with it works okay; but if I try to use it to get audio out of my One in other conditions (playing a game, say, or watching downloaded video) then the video and audio are always badly out of synch - the sound lags at least one second behind the picture.
I'm using the stock HTC ROM, the latest one available in the UK (2.24.401.8).
Anyone have any thoughts as to why this might be happening and what I can do about it?

Mby there is too much data to deliver via bluetooth (high quality audi/video sound) and the hearing aid device is not meant to recive such a load.
When calling to some1, the sound quality is only like 24kbps or something.
Just a thought

That might result in there either being no sound at all or in the sound quality being very poor, but I don't see that it would result in reasonable-quality sound running 1 second behind the picture...?
The device itself is designed to handle fairly high quality sound: as well as receiving Bluetooth signals it can take analogue audio input via a 2.5mm stereo jack socket, and it also has a separate "base station" transmitter which you can plug into (say) the headphone socket of your TV: the transmitter then sends a signal wirelessly to the MiniTek (using a proprietary version of Bluetooth) and the MiniTek relays it to the hearing aids. Using either the direct-line input or the wireless transmitter works quite nicely, and there's no perceptible lag problem there.

I should have said, I've been onto Siemens tech support about it, and they're adamant that it shouldn't be doing this, and they don't know why it is. So I'm looking for a problem at the phone end.

i've experienced the same issues on various BT-Receivers and Smartphones. Seems to be a general issue. So far, this 1 second lag was present on all combinations of:
Phones: Samsung Galaxy S2 / iPhone 4 / HTC One
Receivers: Creative D100 / Creative D200 / Belkin BT Adapter
As i found out so far, this problem occours when the receiver can't handle the apt-x codec and audio has to be resampled to the older SBC codec. Found one thread kinda dealing with this topic, but haven't tried it out for myself at the moment. I'll do some testing later when i'm at home.
