The QAudioCaptureSource class provides an interface to query and select an audio input endpoint.
QAudioCaptureSource provides access to the audio inputs available on your system.
You can query these inputs and select one to use.
A typical implementation example:
QAudioCaptureSource* audioSource = new QAudioCaptureSource; QMediaRecorder* recorder = new QMediaRecorder(audioSource); recorder->setOutputLocation(QUrl("test.raw"));
The audiocapturesource interface is then used to:
- Get and Set the audio input to use.
The capture interface is then used to:
- Set the destination using setOutputLocation()
- Set the format parameters using setAudioCodec(),
- Control the recording using record(),stop()
