NameDescription                              ConstraintsTypeOn
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         
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.
