– Fixed possible crash when Init Audio node is called while playing audio
2019-05-17 v1.04
– Fixed special characters encoding of friendly device names, no more strange chars in audio device names.
– Added GetInputDeviceNames, this node returns a list with input devices.
– Renamed GetAudioDeviceNames to GetOutputAudioDeviceNames
– 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

– 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 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 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.
– New node Get Capture Time, returns the current capture elapsed time
