The real power of BioExplorer comes from the ability to connect signal processing and display objects any way you want.

The following objects are available for use in the Signal Diagram:

AND
The output is the logical AND of two or more signals

Audio Player
Plays audio files (mp3, wma, wave, midi, etc.)  Volume and Play/Pause can be controlled by one or more signals.

Averager
Calculates the average value of a signal over a specified time period.

Bandpass Filter
Filters a signal, allowing frequency components that are between the low band edge and the high band edge to pass through, and attenuating components outside this range.  Outputs the filtered signal as well as the amplitude of that signal.

Bar Graph
Graphically indicates the current value of a signal.

Button  NEW!
Allows you to manually set the state of a signal.

CD Player
Plays audio CDs.  Volume and Play/Pause can be controlled by one or more signals

Coherence
Calculates the coherence between two signals.

Continuous MIDI
Plays a continuous MIDI note.  Volume, Pitch, and Play/Pause can be controlled by one or more signals.

Correlation
Calculates the correlation between two signals.

Counter
Counts properties of a signal (rising edges, falling edges, time high or time low).

Difference
Outputs the difference between the current sample and the previous sample.

Dominant Frequency
Calculates the dominant frequency (the frequency component with the largest amplitude) of a signal.

DVD Player
Plays DVDs.  Volume and Play/Pause can be controlled by one or more signals

Expression Evaluator
Uses a user-defined expression to calculate the output based on one or more signals, e.g. '( In2 - In1 ) / (In1 + In2 )'.

Max  NEW!
Outputs the maximum value of a signal.

Mean Frequency
Calculates the mean frequency in a given bandwidth.

Meter
Indicates the current value of a signal.

MIDI
Plays musical notes at a periodic rate.  The volume, note, and timing can be controlled by one or more signals.

Min  NEW!
Outputs the minimum value of a signal.

NOT
The output is the logical NOT of a signal.

OR
The output is the logical OR of two or more signals.

Oscilloscope
Displays one or more signals over time.

Power Ratio
Calculates the ratio of the power in two frequency bands, or the percent of the total power contained in one frequency band of a signal.

Pulse Detector
Given an EKG signal, determines the current pulse rate.

Source
This object represents a channel on a device (e.g. BrainMaster channel 1, etc).  Source objects are used to get data from a device into the Signal Diagram.

Spectrum Analyzer
Displays the spectrum of a signal.  Currently supports four different modes: spectrogram (shown below), bins, compressed spectral array, and 3D.

Standard Deviation
Calculates the Standard Deviation and Mean of a signal over a specified time period.

Threshold
This object compares a signal to a threshold.  You can set the threshold manually or have the object adjust it automatically based on characteristics of the signal.

Tone Generator
Generates an audio tone.  Frequency, Volume, and Play/Pause can be controlled by one or more signals.

Trend  NEW!
Displays the mean value of one or more signals over a user specified time period (e.g. 10 minutes). New data is added to the right side and the display scrolls to the left, so the last 'x' amount of time is always visible.

Video Player
Plays video files (mpeg, wmv, avi, etc.)  Volume and Play/Pause can be controlled by one or more signals
