On-Off Mouse-Keyboard By Microphone Sound Level

4 posts in this topic

Hallo, I need to make in practice a application running in WIN7.     This application must read continuously the sound(noise) received from the microphone and, if the level of the sound(noise) is higher that a value, to activate to display a Jpeg image on the screen and at the same time to deactivate the sound, the mouse and the keyboard. To have a delay time and after the delay time to reactivate the sound, the mouse and the keyboard.

This application must start at StartUp of PC.

I need to use this application in a computer class room at every PC with WIN7.  

This can be a batch file or a C++ or everything else.

tanidani,

We do not produce code to order - and what we do produce is in AutoIt. So I suggest you try a "rent-a-coder" site. :)

I have received this informations from Matthew van Eerde:

If you had said Windows 8 I would have recommended the MediaCapture API.

As it is, with Windows 7 I suggest using IAudioMeterInformation.

When your program starts up, grab the default recording device via IMMDeviceEnumerator::GetDefaultAudioEndpoint and activate an IAudioMeterInformation.

Then query the peak value in a loop, and if it exceeds your threshold value, do whatever.

IMMDeviceEnumerator *pMMDeviceEnumerator
hr = CoCreateInstance(
    __uuidof(MMDeviceEnumerator), NULL, CLSCTX_ALL,
 
    __uuidof(IMMDeviceEnumerator),
    (void**)&pMMDeviceEnumerator
)
if (FAILED(hr)) { ... }

IMMDevice *pMMDevice
hr = pMMDeviceEnumerator->GetDefaultAudioEndpoint(eCapture, eConsole, &pMMDevice)
if (FAILED(hr)) { ... }

IAudioMeterInformation *pAudioMeterInformation
hr = pMMDevice->Activate(
    __uuidof(IAudioMeterInformation),
    CLSCTX_ALL,
    NULL,
    (void**)&pAudioMeterInformation
);
if (FAILED(hr)) { ... }

while (...) {
    float peak;
    hr = pAudioMeterInformation->GetPeakValue(&peak);
    if (FAILED(hr)) { ... }

    if (peak > ... ) { ... }

    ...
}

tanidani,

By a strange chance someone highlighted >this script earlier today - it looks like it might help you. :)
