The Voice Recorder element is capable of capturing audio input (e.g voice) and writing it into a Wav file. The element uses the WaveOut API. It automatically starts recording on the onset of the parent event.

| Sample Rate | Defines the sample rate of recorded clips, in bytes per second for each channel. | | Int32 | |

| Audio Device | Index of the selected audio input device that will be used for recording. Set to 0 for the system default device. | | Int32 | |
| Buffer Length | Defines length of the recording memory buffer in ms. Each time when the buffer is filled its data is copied and added into a Wave file. If the parent event is deactivated between two consecutive copings, the last part of recording can be lost. To avoid this, make the buffer length as short as necessary but mind the performance cost. | | Int32 | |
