Hi,
I found this reg tweak which looks good however, I have a couple of questions before I go ahead with it.
I already have a "bitpool" value of 30. Can I just change this too say 48? Or do I have to add another dword?
What exactly does this tweak improve.....is it the quality of sound that I will hear from my handfree in my car???
Improve BT A2DP sound quality
[HKLM/Software/Microsoft/Bluetooth/A2DP/Settings]
Add new dword, Value name=BitPool; Value data=48 (Decimal)
Modify, Value name=UseJointStereo; Value data=0 (Decimal, Originally 1)
For BitPool:
Microsoft suggests the following bitpool values for optimal buffer sizes.
30 - Low audio quality
40 - Medium audio quality
48 - High audio quality
58 - Excellent audio quality
Chose one you like. I think 48 is good enough.
For UseJointStereo: use 0 instead of 1, then you got the real stereo.

you change the current dword. it willl assign more memory / processing power to the application... why are you changing it?
in music apps there is a buffer size which is a happy medium between quality of sound vs latency...
you can probably push it to the max, but you may find that your phone degrades in usability / the amount of time it actually takes to hear / respond.
change it, soft reset and test... if you notice no problems then great, if you get glitches then change it back. i doubt you will get any problems you cant get out of, but its good practice to run a backup of the registry before you do any changes just in case!
better to be safe than sorry!!!
Hello. I wonder if there are tweaks to improve the bluetooth headset profile (audio gateway servive, the old-timer, not a2dp?) transmittable audio quality. The point is the audio quality of my speech (thats digitized from mic) sounds like low sample rate audio (not low bitrate probably). Are there any tweaks left if I exclude the bitpool tweak that I tweaked with Advanced Config Tool and which did not work :S
Dear all,
...tried again to jump to another device, but it seems I cannot get rid of my old Tornado
I have measured the audio quality of the Asus P565 and I was shocked how poor it is - even lower than the LG KS20 which was my first disappointment. As I bought the device very cheap on ebay with a broken LCD, not a big loss - but I just cannot believe it!
So if anyone could help me out by measuring the audio quality of your P565 / XDA Zest? Don't worry, it is not so hard to do!
You could set up an own measurement with the free RightMark Audio Anaylzer (RMAA) from: http://audio.rightmark.org/index_new.shtml
Definitely the option to go if you are interested in the topic. Unbelievable what detailed info you get with just the PC soundcard!
Easier is you just playback (all equalizers off - Dolby surround off - maximum volume) the .wav file found here: http://www.tobbbie.de/rmaa/Testsignal.rar and record the result via the line-in of your PC soundcard to another .wav file. You need to know how to record an audio file on your PC - do it with standard CD quality (44kHz, 16bit).
Tell me where to pick up the recorded file - I will have RMAA do the analysis.
Please see what will be the results of such an audio analysis:
Good - HTC Tornado: http://www.tobbbie.de/rmaa/TornadoWM6-plugged.htm
Poor - LG KS20: http://www.tobbbie.de/rmaa/KS20 -2 [via MD8000].htm
Very poor - Asus P565: http://www.tobbbie.de/rmaa/P565-no-usb.htm
All of them were done with the same setup on the same PC.
Please help - I really want to spend the money on a new LCD only if I can use the device as a good wired audio player. Please do not suggest A2DP - I know it should be much better (correct settings anticipated), but the power drain due to compression and BT sending is big - so reducing playback time.
Hi all,
i read many thread on that but nothing really clear so...
All you need is an unlocked wp7 device with some register editor or provxml, Schaps's advanced conf seems to deal with it too (i prefer typing my registry modifs).
I suggest trying to listen a real stereo with 48000hz sample rate...have to be a professional musician to hear differences when setting that rate higher.
HKLM\Software\Microsoft\Bluetooth\A2DP\Settings
BitPool : Dword = 51
UseJointStereo : Dword = 0
------------------------------------
(what's next could be linked with the kind of BTheadphone u use)
HKLM\Software\Microsoft\Bluetooth\Device\........\Services\..........(then u should see u're in stereo sound settings)
enabled : Dword = 1
------------------------------------
I tried many others entries and those are the most stable. No cliks, bips, stops or distortions...sound is wide and heavy as it should be, if not, try some others headphones.
While the audio quality is fine (Quite a bit better with your tweek for sure), do you notice a lag in the audio when viewing video on your device? On my Newly flashed Arrive, it is a noticible lag that sort of destroys the viewing experience.
the lag appears when watching a video with audio over bluetooth or just simply watching a video (audio over device's speaker)?
I won't help you very much because i don't watch videos on my phone...
sometimes i open a youtube link to see a clip but never noticed any issues.
Only when having a video's audio go through Bluetooth. There has never been a lag with the speaker.
Tinkering with some settings and taking a few notes from some old WM 5-6.1 threads which share the exact same reg entries has made the audio sound great, but I'm not sure if the lag is gone or not yet. Some YouTube videos seem to be in sync, others not so much. Netflix is my prime concern as well but I need to test it a bit more before I can say for sure.
Hi there, fellows HOX users,
There were several topics about HOX's poor audio quality when capturing video or recording through voice apps, but still, there weren't any solutions how to solve the lack of frequencies down below ~100-200hz.
I have experience working with sound production, recordings, so I know that these limitations are only made by software. In that case, there must be some kind of solution to improve audio recording quality and enjoy HOX at 100%.
I tried editing srs_global.cfg (found in /system/etc/soundimage) (there was a guy who tried to improve the sound of the phone's loudspeaker and he kinda managed to do it by editing the file), by changing high-pass filter frequency in every "device"
//BLOCK: (srs_hpf_0) HiPass - Device 0
//=-=-=-=-=-=-=-=-=-=-=-=-
srs_hpf_0:hipass_order = 4 // Filter Order -
srs_hpf_0:hipass_frequency = 60 // Filter Frequency -
srs_hpf_0:hipass_is32bit = 1 // Filter Precision (16bit when 0) -
srs_hpf_0:hipass_skip = 1 // Skips High Pass Filter when true - toggle

but there aren't any results.
I don't really understand the types of devices and that they do (WOWHD, TruEQ, CSHP and so on).
Maybe there is any other cfg files who process audio input, because it's the same high-pass filter when recording on internal mic and with external 3.5mm mic.
Let's try to solve this problem everybody, because, as HTC support said
HTC is not designed for capturing things in loud environments

Yeah, whatever... It can do it!

Don't mess with HPF, REALLY DON'T!
I have been experimenting with SRS trumedia 51 and music, HPF messes up when enabled!
these settings you have posted are from SRS_global which won't really do much, install musicBox and you can get SRS working...
There is a reason why you sould not enable HPF without know what values are right, I tried this and it made a mini explosion noise (a sqeek then a loud POP) when starting audio, I highly recommed you do not mess with it. Anyways, SRS will NOT do anything with audio recording, your best place to find audio recording values are in the media_profiles.xml in /system/etc
SRS has nothing at all to do with recording audio, only to output the SRS effect.
I hope this info helps
WOWHD is SRS WOWHD, this is a sound effect which enables a true surround sound experience.
TruEQ is SRS's native EQ settings, not much to say here...
CSHP is SRS CS Headphone. Or as I would like to call it, Dolby Digital 5.1 (Because it IS the exact same effect) (CSHP is only used in srs_truemedia_51) (HTC Enhancer uses this file)
Thank's for your answer.
I can't understand, how nobody is interested in improving audio recording quality, when it's obvious that it's a software limitation thing.
We have an almost perfect phone with good camera, but we can't fully enjoy watching and LISTENING recorded videos, because some "clever" people in HTC decided that it's normal to high-pass the mic and put a compressor on it, without any gain control - in result we have a tragic audio from loud concerts and even LOUD voice conversations (where people are sceaming a little bit).
Maybe someone has a solution?
Maybe HTC will offer switching to a ****ty iphone, which has almost perfect audio recording quality (for a phone)?!
