How to stop Audio recording when no sound is detected
Hello friends,
I want to develop the application which is record audio (implementation of this part, I already had)... but I want to stop recording when device has been not detect any noise over 2 sec audio...
I already convert the data byte in data short tosigned that is giving me the length of the sound...
int level = (signedShortToInt (b) * 100 / 32767); b is the data buffer
mutable public static int signedShortToInt (byte [] b) {}
result int = (b [0] & 0xff). (b [1] & 0xff)<>
return the result;
}
I'm familiar with the sound of noise of air is in normal recording...
Air noise level not more than 100 (im guessing).
so I had checked the voice level is below 100 it will stop recording...
My idea is correct or not?
private void jesuissuper (byte [] buffer) {}
for (int i = 0; i)< buffer.length;="" i++)="">
Byte [] b = new byte [] {[i] buffer, buffer [i + 1]};
int level = (signedShortToInt (b) * 100 / 32767);
If (100 > level) {}
Voice.StopThread ();
}
}
}
My Question is... How can I stop the recording when the level is low up to 2 sec and it is the Correctmethod to find the sound level?
Hello guys,.
I have not found any Solution for this so I drop this idea...
I had found my solution up to convert PCM ampltude data... Using the Amplitude level I can is find the noise data and hat is given voice. and stop Audio in usin it
But not audio recorded in the camera store...
Thank you...

On incoming emails: how to stop creating customers when no Match?
On incoming emails: how to stop creating customers when no Match?
We have encountered a problem using the incoming e-mail. (RP08 V9.0)
It seems that when an incoming e-mail message is processed, he tries to associate with a customer by matching the email address. If it cannot find a match with the email, a new customer is created. In our case with this client, they have something like 20,000 customers, but few have corporate e-mail addresses and they are employees of causality.
We need these incoming calls to be bound to a generic customer or not, so the service desk can make a corresponding manual. All clients are automatically filled from their payroll in a mansion controlled system, so with the current behavior of get us many customers duplicate being created, which is an administrative nightmare.
Does anyone know how you can stop this happening and creation the link that these incoming calls to a generic customer account set in place for this purpose.
There is no setting of system to stop this behavious, I know. Would be nice if there was J

I connect on - the work of sound system very well. Media player works fine. The next time I log on - no sound system. Everything is plugged, convenience store finds no problems, Media player goes through all the steps and looks that don't worry, still no sound. I have download a fix for the VIA recommended by Dell Driver. I did, and it still has the same problem. I can close, reconnect, and then the sound will work. Sometimes I have to close and log on twice in a row so he can launch.
Can someone point me in the right direction to solve this problem? I am working on a Dell Inspiron 546 AMD Athlon II x 2 215 2.70 GHz and 64-bit with 400 GB of RAM. I installed Windows 7 but when I dug deeper into the service code for this machine which found at some point in time he had installed Vista. This could be the same Vista to Windows 7 problem audio, everyone seems to have? I bought this Staples announced new with Windows 7 as operating system.
I did research on all forums and responses and am unable to check if I have a "sound card". I'm not used with the terminology so even if I follow the Microsoft instructions to find the right place to check and see, I do not understand what I see when I'm there. It is said: ATI high definition Audio Device and VIA High Definition Audio. Is this to say that I have a sound card or I should get it a? If I buy a sound card will it fix my audio problem?
Even though I had my audio problem fixed, I was disappointed by the sound quality of the speakers on this new system up to date. My speakers on my old computer (which lasted from Windows 98) were by far superior in sound quality. I don't understand why they sound so crappy and barely louder, and when you show the to they have a rattle for them. I tried plugging my old speakers on my new computer, but nothing happens. My new speakers have a Plug and a USB port. I don't know what is... why goal can not use my 'old'?
Finally, I want to record my vinyl on discs and need a great sound system. Any advice?
I removed all the ATI Audio as suggested. The result in the short term is that the audio quality is improved. I no longer hear the "crackling" when the sound is turned on. I'll answer more if the issue of audio (works) continues to be a problem because the fix. If you don't hear from me, then please consider the problem solved and my thanks to you.

How to stop ProgressEvent.Progress when bytesLoaded, bytesTotal
I want to stop ProgressEvent.Progress and two seconds to determine if the modem Internet connection. Is there a way to stop ProgressEvent.Progress when bytesLoaded, bytesTotal? Right now, the event continues until the entire *.jpg file is loaded and/or creates a fatal error, zipper. Here is the code I use:
var myTimer:Timer = new Timer (1000,2);
var myTimerCount:uint = 0;
This.Stop ();
function preloaderSpeed (): void {}
var speedName:String = "ImageLoadSpeed.jpg";
var request: URLRequest = new URLRequest (speedName);
speedTest.load (request);
speedTest.contentLoaderInfo.addEventListener (ProgressEvent.PROGRESS, speedProgress);
speedTest.addEventListener (Event.COMPLETE, speedCancel);
speedTest.addEventListener (IOErrorEvent.IO_ERROR, ioErrorHandler);
}
function ioErrorHandler (): void {}
trace ("ErrorHandles");
}
function speedProgress (event: ProgressEvent): void {}
myTimer.start ();
myTimerCount = myTimer.currentCount trace (event.bytesLoaded + "" + myTimerCount);
If (myTimerCount == 2)
{
MyEventArgs;
trace ("myTimerCount == 2");
If (event.bytesLoaded < 20000)
{
trace ("bytesLoaded < 20000");
modem connection
loadDialUp();
}
on the other
{
trace ("bytesLoaded > 20000");
loadIndex ();
}
}
}
You can stop receiveing the event by removing an event listener, but the downloding not stop.
To stop the download, use. close() the loader to remove event listener ProgressEvent class
speedTest.close ();
