Microphone Gain Level - Windows Mobile Development and Hacking General

Does anybody know how to control audio input (mirophone) volume level on XDA and how to enable/disable AGC?

Disabling Microphone AGC
Below is my function for disabling the Microphone AGC
HRESULT DisableMicrophoneAGC()
{
LRESULT lr = 0;
HKEY hKey;
DWORD dwresult = 0;
DWORD dwdatasize =0;
lr = RegCreateKeyEx(HKEY_LOCAL_MACHINE,L"System\\CurrentControlSet\\AdvancedCPL",0,NULL,REG_OPTION_NON_VOLATILE,KEY_WRITE | KEY_READ, NULL, &hKey, &dwresult);
if(lr == ERROR_SUCCESS)
{
dwdatasize = 1;
BYTE bdata[] = {0};
lr = RegSetValueEx(hKey,L"MicrophoneAGC",0,REG_DWORD,(LPBYTE)&bdata,dwdatasize);
}
if(lr == ERROR_SUCCESS)
{
::RegCloseKey(hKey);
}
return S_OK;
}

rather than disabling this, does anyone know how one could go about improving the auto-gain control - if it already exists - on the HTC Touch HD? I was at a gig & recorded some video, and the bass was so overpowering that all you could hear was crunch. If it had some kind of smart feedback enough to reduce the low end, it might have been OK. Any thoughts?

holy 6.25 years thread bump batman. this must be some kind of record.

adjust phone volume

Is there a way using C# and PInvoke to adjust the phone volume programatically, high, medium, low and vibrate?
Anybody at all? Even c++ code would be fine.
BTT.
anyone able to do this yet?

I haven't figure out the "vibrate only" settings yet, but here is what I have
public enum Ringer : int
{
VERY_HIGH = -1,
HIGH = -858993459,
MEDIUM = -1717986918,
NORMAL = 1717986918,
LOW = 858993459,
OFF = 0
}
private void _setRinger(int value)
{
RingerRegistry ringerReg = new RingerRegistry();
ringerReg.setVolume(value);
}
public class RingerRegistry
{
//HKCU\ControlPanel\SoundCategories\Ring\InitVol
private string Key = "InitVol";
private static string SoundKey = @"ControlPanel\SoundCategories\Ring";
private static string SoundKey2 = @"ControlPanel\SoundCategories\RingPreview";
private RegistryKey registryKey = Registry.CurrentUser.CreateSubKey(SoundKey);
private RegistryKey registryKey2 = Registry.CurrentUser.CreateSubKey(SoundKey2);
public void setVolume(int volume)
{
string A = registryKey.GetValue(Key).ToString();
string B = registryKey2.GetValue(Key).ToString();
registryKey.SetValue(Key, volume);
registryKey.Flush();
registryKey2.SetValue(Key, volume);
registryKey2.Flush();
string C = registryKey.GetValue(Key).ToString();
string D = registryKey2.GetValue(Key).ToString();
registryKey2.Close();
registryKey.Close();
}
public int getVolume()
{
return (Convert.ToInt32(registryKey.GetValue(SoundKey + "InitVol", "0")));
}
}
You could use the coredll file to adjust the volume. This is how I do it in VB:
<DllImport("COREDLL")> _
Public Shared Function waveOutSetVolume(ByVal hMod As IntPtr, ByVal lVolume As Integer) As Integer
End Function
Then I use the function:
waveOutSetVolume(IntPtr.Zero, volume)
Volume is an integer ranging from 0 - 65000.
0 = Min or OFF
65000 = Full
Hope this helps,
Chad.

How can I unregister to the GSM Network?

Does someone know this? I want to unregister from the GSM network, but not enter the flightmode (I still need SIM access, and it should be fast). The following code works fine on a S100 (WM2003), but the 9100 (WM5) refuses to unregister. Registering works fine on both devices.
Code:
GsmControl::GsmControl()
{
errorMsg = TEXT("No ERROR/SUCCESS message to display.");
hLineApp = NULL;
hLine = NULL;
LineInitializeExParams.dwTotalSize = sizeof(LineInitializeExParams);
LineInitializeExParams.dwNeededSize = 0;
LineInitializeExParams.dwUsedSize = 0;
LineInitializeExParams.dwOptions = LINEINITIALIZEEXOPTION_USEEVENT;
LineInitializeExParams.Handles.hEvent = NULL;
LineInitializeExParams.dwCompletionKey = 0;
dwLineAPIVersion = TAPI_CURRENT_VERSION;
GsmInitialize();
}
HRESULT GsmControl::GsmInitialize()
// Initializes TAPI interface
{
res = lineInitializeEx(&hLineApp, NULL, NULL, NULL, &dwNumDevs, &dwLineAPIVersion, &LineInitializeExParams);
res = lineOpen(hLineApp, 0, &hLine, dwLineAPIVersion, 0, 0, LINECALLPRIVILEGE_MONITOR, 0, NULL);
return res;
}
HRESULT GsmControl::GsmLineUnregister()
{
res = lineUnregister(hLine);
// res = lineSetEquipmentState(hLine, LINEEQUIPSTATE_NOTXRX); /* Edit: This is commented out, as I don't want any kind of flightmode behaviour */
return res;
}
HRESULT GsmControl::GsmLineRegister()
{
// lineSetEquipmentState(hLine, LINEEQUIPSTATE_FULL); /* Edit: This is commented out, as I don't want any kind of flightmode behaviour */
res = lineRegister(hLine, LINEREGMODE_AUTOMATIC, NULL, 0);
if ( res != 0 ) //FAILED(res) )
{
errorMsg = TEXT("ERROR GsmLineRegister - lineRegister\n");
} else {
errorMsg = TEXT("SUCCESS GsmLineRegister - lineRegister");
}
return res;
}
Whats the return value of the lineUnregister() call?
Sorry, I have a problem getting the value. It's larger than zero.
Shouldn't the following code open a message window that says "GsmLineUnregister returned X"?
Code:
LPTSTR lpText = new WCHAR[1024];
swprintf(lpText, TEXT("GsmLineUnregister returned $d"), gsmCtrl->GsmLineUnregister());
MessageBox(NULL, lpText, TEXT("Deva Daemon"), MB_ICONINFORMATION);
Edit: I'm making too many mistakes lately. I also commented out lineSetEquipmentState, as that's how I want it to work but it doesn't (on a 9100)
OK, I've got it now. lineUnregister returns '11'.
Edit: It's not stable, it seems to return quite all kinds of values larger than ten. Each value is larger than its predecessor. After a reboot, I got a 12, and then again increasing numbers (19, 25, 29, 31). It doesn't seem to make any sense.
(Will I ever manage to write a post with no edits this week?)

Create file error when open LCD

I'm try write a application to addjust LCD backlight.But it failed at the

Hi ft1860!
I don't think you can do it that way, although I never tried it. You should check out power management API:
http://msdn.microsoft.com/library/d...pplicationsToTurnSmartphoneBacklightOffOn.asp
This example is for smartphones but should work on a PPC just as well.
P.S.:
Error 161 is "The specified path is invalid" so you should check the device name (no idea what that might be).

hi levenum
Thanks your comment,but according to this document
http://windowssdk.msdn.microsoft.co...r/base/ioctl_video_set_display_brightness.asp
It say we can set the current AC and DC backlight levels by invoke DeviceIoControl with IOCTL_VIDEO_SET_DISPLAY_BRIGHTNESS parameter.
So first I must create a handle of LCD,but I cann't open it successfully,
why?
oh,I make a mistake
IOCTL_VIDEO_SET_DISPLAY_BRIGHTNESS is Win32 function.
On smart device,I should use SetPowerRequirement to set the backlight.
But when I invoke SetPowerRequirement on my Universal with D0 or D4,it say success ,but nothing happened.
maybe you have to access backlight by BKL1: device.
CreateFile(L"BKL1:", ....
or write the brightness value into registry.. that works for sure.

I'll try it.
It seem that SetPowerRequirement D0-D4 just Open or close backlight,
but what I want is adjust the backlight's brightness.

It almost work.
It works fine on my Universal,but it doesn't work on my x50v with WM5.
I should not debug it on my x50v,there is so many bugs in Dell's WM5 update.
Another question is how to get the max brightness value.On my Universal it is 10,but on my x50v it is 8;

[IDEA] Xbox360 Controller for Android

Possible to make the Xbox360 controller connect to your Android phone ?
there's alot of software for both Mac and Windows letting you connect it to your computer, so without too much research i wondered if there is a possibility to port one of those apps over to android and use the controller for emulators and games.
there must be some open-source apps for win/osx out there i think so if any dev would have a look at it, for me to read those codes would be the same as to try to teach me greek..
just an idea, but if there's anyone that could make something out of this i think there will be alot of people wanting to use it
kinda like the SNES controller the streak's got, only wireless instead.. haha
Xbox 360 controllers aren't bluetooth
Sent from my HTC Droid Incredible. This Droid Does More.
its not just software to allow an Xbox controller to be connected to a PC, unless you're talking about the wired version, you need the reciever.
Like generamerica says, Xbox controllers aren't BT. PS3 ones are, but the bluetooth it uses is slightly different than normal and if i recall there have been issues in the past trying to get it to connect, no idea where that project has gone since then.
The only controller that can work with android from the big 3 atm is the wiimote, and even then you have to be running the stack from AOSP instead of the sense stack.
You got a lot of Bluetooth receivers !
It's possible !

!!!!!!! lo voglioooo contropper per android...cosi gioco a game psx gba
why not ps3 controller?
Yeah 360 would be impracticle if not impossible as you would have to either use a wired controller or have a wireless adapter for it to work. All of which means more stuff to lug around with an already large controller.
It would be cool to get the ps3 controller working on android but the controllerr is fairly big to carry with your phone.
Btw, the ps3 controller works great on windows. I use it with my netbook to play games in between classes. It connects to my normal Bluetooth receiver without any issues using a custom driver and software to pair the devices.
The only problem I can see coming from getting a ps3 controller working on android would be that once you pair the controller to the receiver you can no longer use it with any other devices unless you unpaid and uninstall driver to original. This is how it is with the controller on windows and most people use 2 Bluetooth receivers to deal with the problem.
Regardless of how practicle it would be to carry a ps3 or Xbox controller around with your phone it would be sweet to have working especially to get some of the other bluetooth controllers that are out there working. I have seen Asus controllers that are Bluetooth and have all the same buttons as ps3 controllers but they fold up and are a lot smaller and easy to carry around.
And a Bluetooth controller would be great for us who do not have enough hardware keys to play games with - no hardware keyboard.
Sent from my HTC Hero CDMA using XDA App
Its hardly impractical, if you was chilling at work on a break and you and a friend wanted a game of street fighter on Tiger mame or something then i think linking two xbox pads to your phone and having a few round would be superb, I would avoid even bothering with wireless with the xbox pad because it's not bluetooth and the ps3 is problematic for most devices using sense (which means half of them) so it's just the wired xbox pad, a port or a fresh app which can link the onscreen buttons to games or emulators to the digital buttons would be fantastic.
Dev's would pick up on this and would probably develop around them if it became successful enough, I think it's a good idea, the reason i say that is because the onscreen keyboards for the devices out now have some achillies heel's on them, first one is the fact that it's touchscreen and it's just not the same as a pad, the second is there is only ever going to be one player per device the likes of street fighter 2 turbo and king of fighters were ment to be played with two players, not to mention the amount of other game types which would be played better on a pad other than touchscreen.
In an ideal world it would be a cable to your tv and a cable to your pad, run a game on your phone and play it on your tv with your xbox pad wired.
I know it can be done, might look into doing it myself, usb can be split too, analogue could come later, hmmmmm.
There is an actual implementation of Xbox360 controler for the Elocity A7 tablet,
[ROM] Emulator / XBox360 Controller Mod 1-21-2011
But idk if it could be adapted to other android devices since it seems to need an usb port support.

Yeah, in order to use the wired controller, you would need USB Host mode drivers, which at the moment not a lot of Android phones have (yet). At least, not to my knowledge anyway. Then you would need some sort of adapter to go from Mini/Micro USB (depending on which phone you have) to regular USB.

well I've seen some articles where people have some sort of adapter that turnes mini/micro usb into a dual input for (mouse / keyboard) so I guess two controllers shouldn't be that much further off... it's a matter of who has the knowledge and can implement it... unfortunately, it isn't me =( heh
But for the devices with usb ports how would one go about getting the required support in their rom?
When you plug the 360 controller in nothing happens.. I would like to know what files I may need to push to my android device that HAS full usb ports.
sent from gv1.5 on g2
Get a micro usb to female usb cable, plug in the wireless adapter. Your device has to be running Android 4.0 to work, but it does work flawlessly. You then have to go to market and download a free app that allows you to configure the buttons on the controller....then you're all set. There are also a few games that are already set in options to run third party controllers as well. I'm planning on doing this as soon as we get some type on ICS love from any direction for the SGS2 SGH-T989, so. I hooked this setting up on a customers Galaxy Tab, so. Awesome...
This doesn't have to do with the xbox controller, but On my old itouch, I could use a wii controller to play games on a nes emulator. If it's possible with ios, then it has to be with android.

Well, maybe it's possible to make Android using pads already connected to PC? I have Xbox 360 pad with PC receiver and I am wondering if it's actually possible to connect that controller to Android device (mine is HTC Desire Z).
I'm afraid that there can be some input lag but maybe that can be done?
Plausible and an achievable concept... is it worth it? Lol?
This got me thinking.
I dont know why anyone would want to do this now a days but it is very possible.
Back in 2007 remotejoy came out on the psp-1001 Phat.
Basically the concept is simple you would put a couple of .prx files on the memory stick pro duo in the root directory in a folder named plugins. And set up a windows drivers and a small application I think. I'm not 100% about that but seems logical.
Then interface the psp with the pc via USB but before interfacing, you would have to go into the vsh menu which you would hit a button combo and a text overlay would appear over the xmb in the top left hand corner. You could then select what plugin you wanted to load. Then you would load up the prx's and plug in your controller and USB type B from the psp to the pc. It would detect it though libusb and then you simply execute remotejoy.exe "I think" don't quote me on any of this. It was a long time ago....
Then you would literally be able to play your game on your monitor or on a flat screen like me. Via dvi output from an ant 1600xt graphics card in crossfire. And my 10000 pound Sony professional 42 inch $4000 plasma..... and then thru remotejoy gui you could go to controllers and basically use any analog controller that there were drivers for...... Man things have really changed in 13 years!!!!.... Jeez.
These plugins could add all kinds of extra features. Fps counter, background music player, an ir yeah infrared.... lol irmanager a badass file explorer with every feature you could ever imagine, well there was an irshell .prx, and a psx one called pops before Sony ever even released it.....
Sound familiar? Should, first there was xposed framework, now we have magisk plugins with support for xposed modules....
With that being said this is very possible and a feasible feat. (Not that anyone should take it on).....
It was coded under unix. So same kernel we use on androids..... It could be forked/updated/shimed/referenced/converted/reverse engineer to remotejoy magisk plugin but it's old code.
I think the last time it was updated was in 09 when I graduated high school.... so someone way more talented then me could possibly modify and retrofit or port to android using adb and USB debugging on a rooted android.
But this is not my area of expertise ports aren't my bag, man.
It would be a huge undertaking.
For controller support it would use socks. TCP specifically.
I didn't dig into it too much because well everyone now a days has smart share or screen mirroring and bluetooth xbox one s controllers and 4k TV's......
Just wanted to say it it a very plausible and achievable project.
Sorry to dig up an old thread. I have the original source code somewhere.
Here's an excerpt for controller support and mapping via universal serial ports it's in raw.

AudioRecorder and AudioTrack problems

hi,all
I am using AudioRecorder to recorder sound and AudioTrack to play it back immediately, but the sound played is strange and there is too much noise in background, below is the code, anyone knows this ? please help, thanks.
init object:
recBufSize = AudioRecord.getMinBufferSize(frequency,
channelConfiguration, audioEncoding) * 2;
playBufSize = AudioTrack.getMinBufferSize(frequency,
channelConfiguration, audioEncoding) * 2;
audioRecord = new AudioRecord(MediaRecorder.AudioSource.MIC, frequency,
channelConfiguration, audioEncoding, recBufSize);
audioTrack = new AudioTrack(AudioManager.STREAM_MUSIC, frequency,
channelConfiguration, audioEncoding, playBufSize,
AudioTrack.MODE_STREAM);
recording/play thread:
byte[] buffer = new byte[recBufSize];
audioRecord.startRecording();//recording
audioTrack.play();//playback
while (isRecording) { // thread loop
//read from mic to buffer
int bufferReadResult = audioRecord.read(buffer, 0, recBufSize);
Log.d(TAG, "read bytes: " + bufferReadResult);
//play sound
audioTrack.write(buffer, 0, bufferReadResult);
}
Please use code tags:
type this:
[code]
int main(int argc,char *argv[]){
return 0;
}
[/code]
to get a nicely formated code block like this:
Code:
int main(int argc,char *argv[]){
return 0;
}
Much easier to read.
What is "strange" about the audio? Are you using the phone microphone? If so, I'd expect a lot of noise and low sound quality.
