virtual void | updateCaptureBuffer (bool force=false)=0 |
| Grabs samples from the OpenAL buffer into the capture buffer if the OpenAL buffer has reached half full. Should be run once every audio frame, unless threading is enabled. More...
|
|
virtual void | shutdown ()=0 |
| Shuts down the capture device, clearing the internal buffer and setting the audio capture into an uninitialized state. You must call initialize() again in order to reuse this object.

virtual bool | setInternalBufferSize (unsigned int internalBufferSize)=0 |
| Sets the internal buffer size that OpenAL will use to store captured audio between calls to getCapturedAudio() in bytes. Will cause the capture device to be reinitialized. Calling while in use will clear the internal audio buffer. More...

|
pure virtual |
Allows access to the audio data in the internal capture buffer.
Can be called at any time to retrieve recorded audio. It is recommended that you call it every so often with long recordings to prevent the internal buffer from growing too large.
Once successfully retrieved, the captured audio will be deleted from the internal buffer.
- Parameters
-
outputBuffer,: | Pointer to an output array to copy audio data to. |
outputBufferSize,: | Size of the output array in bytes. |
- Returns
- Size in bytes of the data actually copied to the output buffer.
Implemented in cAudio::cAudioCapture.
virtual bool cAudio::IAudioCapture::isUpdateThreadRunning |
( |
| ) |
|
|
pure virtual |
Returns if the thread used to update all Audio Capture Objects is running.
Note: Will always return false if threading is disabled.
The library automatically shuts down the thread if no Audio Capture objects exist and will restart the thread on creation of a new object.
- Returns
- True if the thread is currently running, false otherwise.
Implemented in cAudio::cAudioCapture.
