| Settings |
| Audio Device | Defines an audio device for recording. | | Int32 | |
| Capturing Engine | Defines the engine for audio capturing. WASAPI is the best for timing accuracy but it not supported in Windows XP. In contrast, WaveIn works on any Windows OS | | enAudi.. | |
| Volume | Defines the capturing volume for the WaveIn engine. Keep -1 for the system volume | | Double | |
| Audio Buffer Length | Defines length of a memory buffer on sound hardware (in ms). Make the buffer length smaller for shorter recording latency but mind a possible performance cost. | | Int32 | |
| Sampling Rate | Defines the sampling rate of capturing. The value must supported by the sound hardware | | Int32 | |
| Signal Generator |
| Signal Source | Defines a source for the signal. The emulated rhythmes can be used for offline validation of the chosen analysis settings | | enEmul.. | |
| Emulated Sampling Rate | Defines the emulation sampling rate (samples per second), when data is generated or streamed from a file. | | Double | |
| Primary Frequency | Defines the frequency of the primary rhythm in the generated signal, in Hz. Assign the zero to exclude the primary frequency from the generated signal. | | Double | |
| Secondary Frequency | Defines the frequency of the secondary rhythm in the generated signal, in Hz. The secondary frequency magnitude is a half of the primary frequency magnitude. Assign the zero to exclude the secondary frequency from the generated signal. | | Double | |
| Noise Level | Defines the noise level (in % to the norm magnitude of the primary frequency). The noise is added to the generated signal. Assign the zero the exclude the noise from the generated signal. | | Double | |
| External Datafile | Opens the dialog for selecting a data file containing a stream of double numbers representing a signal. If a file name without a path is defined, the data file will be picked up in the location of the experiment file. | | String | |
| Channel Configuration |
| Selected Channels | Defines what signal channels are selected for acquisition within EventIDE. Selected channels are registered in the EventIDE signal pool at runtime and become available for the signal analysis elements. | | IList | |
| Selected Channel Count | Indicates how many signal channels are currently selected for acquisition | | Int32 | |
| Total Channel Count | Indicates how many signal channels are available for acquisition in the total | | Int32 | |
| Buffer Size | Defines the size (in samples) of a circular buffer that stores incoming signal data. | | Int32 | |
| Runtime Control |
| Reset Signals Now | Runtime commands that resets the signal buffers and data acquisition | | Boolean | |
| Control |
| Is Enabled | If set to false the element is completely omitted when the experiment is run | | Boolean | |
| Title | Title of the element | | String | |
|
Microphone Signal Element records and buffers a real-time microphone input.
