Detailed Description

This recorder gets frames from the microphone. It is configured with the driver number of the microphone and the frequency. You can retrieve the list of available drivers on the computer with the method getRecordDrivers(). It can be also created to record in a file while getting frames from the microphone stream. It records by default in wav but if the file name contains ".mp3", it will automatically encode when the process is finished. The recording is finished when the maximum size set is reached.

Example recording to a file and processing the frame:

    UAudioRecorder* recorder = new PlayRecorder("fileName.wav", 100);
    Frame frame;
    unsigned int frameId = 0;
    recorder->start();
    while(recorder->getNextFrame(frame, frameId))
    { 
      ...process the frame...
      ... break when a condition is reached...
    }
    recorder->stop();
      delete recorder;

Member Function Documentation

virtual void UAudioRecorderMic::mainLoop

(

)

[protected, virtual]

Pure virtual method mainLoop(). The inner loop of the thread. This method is called repetitively until the thread is killed. Note that if kill() is called in mainLoopBegin(), mainLoop() is not called, terminating immediately the thread.

See also:

mainLoop()

kill()

Implements UThreadNode.

virtual void UAudioRecorderMic::mainLoopBegin

(

)

[protected, virtual]

Virtual method mainLoopBegin(). User can implement this function to add a behavior before the main loop is started. It is called once (before entering mainLoop()).

Reimplemented from UThreadNode.

virtual void UAudioRecorderMic::mainLoopEnd

(

)

[protected, virtual]

Virtual method mainLoopEnd(). User can implement this function to add a behavior after the thread is killed (after exiting the mainLoop(), work is still done in the thread before exiting).

Reimplemented from UAudioRecorder.
