Added	Added Audio Device selection nodes Now you can select the audio device to play and capture the sound. Set default Device(s) Player/Capturer Audio node must be called before Init Player/Capturer Audio node. If the default audio device is not set then the system default audio device is selected More detailed info into Documentation page

Fixed	Fixed crash on wrong sound path during Player Initialization
Added	Added channel selection mode in visualizer initialization All in one: Accumulates all channels data into only one array Select one: Returns only the channel specified in Channel option Split all: Returns each channel into one array. Use “By Channel” nodes to retrieve the results
Added	New amplitude analysis configuration node. Now Amplitude analysis use the same node structure as frequency spectrum and beat tracking analysis. Initialization + Getter
Changed	Removed GetAmplitude parameters
Added	Added multi-channel Support. Now you can retrieve the results for each channel separately, select Split_all option in “Channel selection mode” during the analysis configuration and use the “By Channel” nodes to retrieve the results
Changed	Changed GetBeatTrackingVariance node, now calculates Average and Variance with the same node. If you only need the average result you can continue using GetBeatTrackingAverage node
