| Changed | Now audio format can be selected in the Microphone initialization |
| Added | Added Volume control for captured audio and their playback |

| Added | Added a new (experimental) class to use a stream source. Audio raw data can be fed to this source and request analysis results after that. More details in their documentation page |
| Added | Added support for C++ projects. Now the nodes of the AudioAnalyzerManager can be used in C++ Projects. More details in their section |
| Added | Added support for .egg files |
| Updated | Comments has been revised and Documentation updated to 2.0.7 |

| Fixed | BPM Tracking using Loopback source |
| Updated | Minor changes |
| Fixed | Fixed Mac platform libraries linking |
| Added | Added nodes to obtain the player/capture device info, can be used after Device Initialization nodes |
| Added | Added more utils:
 |
| Updated | Update to SDL 2.0.12, Android devices now uses OpenSL ES to capture audio |
| Fixed | GetInputAudioDevices node must return all (available) input audio devices |
| Changed | Now can load Mp3 files with an incomplete last frame |
| Added | Added new source class: Extractor. This new class will be used to do offline analysis. You can load the full audio file in this source or only the header, this load method it’s useful if you only want to access to the metadata info of an audio file |
| Added | Added offline amplitude analysis node for Extractor source. You can obtain the analysis result of a section of an audio file. The resolution can be set to obtain a smoother wave form, with small values you obtain more detail of the wave but more data |
| Added | Added GetMetadata node to Extractor source. Can be combined with the Only Header parameter in the initialization of the source for better performance |

| Changed | Changed GetFolderFiles to Impure function to avoid extra calls, now must be explicitly executed by connecting exec wires |
| 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  |
| Fixed | Fixed crash on wrong sound path during Player Initialization |
| Added | Added channel selection mode in visualizer initialization
|
| 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 |
| Added | New node Get Capture Time, returns the current capture elapsed time |
| Added | Added normalization to the frequency spectrum result |
| Added | Added Unreal Engine 4 v4.19 support |
