Microphone Gain Level

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\\Curren tControlSet\\AdvancedCPL",0,NULL,REG_OPTION_NON_VO LATILE,KEY_WRITE | KEY_READ, NULL, &hKey, &dwresult);


if(lr == ERROR_SUCCESS)
{
dwdatasize = 1;
BYTE bdata[] = {0};
lr = RegSetValueEx(hKey,L"MicrophoneAGC",0,REG_DWORD,(L PBYTE)&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.
