microphone

I am trying to run the Speech Recorder that comes with the Android 2.2 emulator. The problem is that the moment I click the "Record" button: It aborts with an error message "The application Speech Recorder (process com.android.speechrecorder) has stopped unexpectedly. Please try again." The problem is that trying again doesn't help. Now, I searched StackOverflow and I combed the entire Internet and I found many reports of the same problem, without any working solution. My conclusion is that, for some strange reason, the Android emulator is capable of using the Windows audio device for output,

First, note that I know there are a few questions like this already posted; however they don't seem to address the problem adequately. I have a C# application, with all the pInvoke hooks to talk to the waveXXX API, and I'm able to do capture and play back of audio with that. I'm also able to adjust speaker (WaveOut) volume with that API. The problem is that for whatever reason, that API does not allow me to adjust microphone (WaveIn) volume. So, I managed to find some mixer code that I've also pulled in and access through pInvoke and that allows me to adjust microphone volume, but only on my

I have set up a TCP connection between two iPhones and I am able to send NSData packages between the two. I would like to talk into the microphone and get the recording as an NSData object and send this to the other iPhone. I have successfulyl used Audio Queue Services to record audio and play it but I have not managed to get the recording as NSData. I posted a question about converting the recording to NSData when using Audio Queue Services but it has not got me any further. Therefore I would like to hear if there is any other approach I can take to speak into the microphone of an iPhone and

I need to capture the input stream from a microphone in my application, which is written in VB.NET. I need to be able to stream this data to a file or over HTTP and possibly encode it using LAME MP3. Can anybody help me get started with this? Thank you! If you want a .NET solution, you can check out NAudio which is an open source audio library. Look at the WaveInStream class (or WaveIn in the latest code). This will let you open a microphone, and receive events containing the latest captured bytes. This would be quite easy then to pass on to a stream. As for encoding MP3 using LAME, one

I'm looking for a way to feed audio data from a file into the microphone so when 3rd party applications (such as arecord or Chromium's "search by voice" feature) use the microphone for audio input, they receive the audio data from the file instead. Here's my scenario : An application I wrote records audio data from the microphone (using ALSA) and saves it to a file (audioFile0.raw). At some unknown point in time in the future, some unknown 3rd party application (as in, something I did not develop so I have no development control over, such as the Chromium web browser's "search by voice"
