Fixed

Fixed Mac platform libraries linking

1.10 2020-08-06

Added	Added nodes to obtain the player/capture device info, can be used after Device Initialization nodes

Fixed

Fixed possible crash when Init Audio node is called while playing audio

1.04 2019-05-17

Fixed	Fixed special characters encoding of friendly device names, no more strange chars in audio device names
Added	Added GetInputAudioDevices, this node returns a list with input devices
Changed	Renamed GetAudioDeviceNames to GetOutputAudioDevices
Added	Added Loopback Input, now you can capture the audio directly from the system device. You can do the analysis from the audio played from other applications. Nodes added: Init Loopback Audio Inix Loopback Audio Ex Unload Loopback Audio Get Default Device Loopback Audio Set Default Device Loopback Audio Start Loopback Stop Loopback Is Loopback Capturing Get Loopback Capture Time More detailed info into Documentation page
Added	Added new Example project: Loopback Test

1.031 2019-04-20

Fixed	Fixed crash with some MP3 formats

Added	Added new player node with more options: Loop playback and Starting time. You can define the number of loops and bind and event for each loop end too. Each loop starts from StartTime position
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

1.02 2019-03-12

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
Added	Added Beat-per-minute counters to Beat Tracking nodes, now you can track the bpm of an interval of beat tracking samples and the result with max frequency
