FixedFixed Mac platform libraries linking
FixedBPM Tracking using Loopback source
UpdatedMinor changes
1.112020-08-10
FixedFixed Mac platform libraries linking
1.10 2020-08-06
AddedAdded nodes to obtain the player/capture device info, can be used after Device Initialization nodes
AddedAdded more utils:
  • FrequencyToMIDI: Frequency Hz to MIDI note value
  • AmplitudeTodB: Amplitude to dB conversion
UpdatedUpdate to SDL 2.0.12, Android devices now uses OpenSL ES to capture audio
FixedGetInputAudioDevices node must return all (available) input audio devices
1.09 2020-03-26
ChangedNow can load Mp3 files with an incomplete last frame
AddedAdded 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
extractor_init
AddedAdded 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
extractor_analysis
AddedAdded GetMetadata node to Extractor source. Can be combined with the Only Header parameter in the initialization of the source for better performance
extractor_util_1
UpdatedAdded Extractor sample project [Link]
1.08 2019-12-28
AddedAdded Pitch tracking real-time analysis (fundamental frequency)
doc_visualizers_bp_spectrum_peaks
AddedAdded Pitch Tracking sample project [Link]
AddedAdded 4.24 Engine version support (IMPORTANT: UPGRADE NOTES, the plugin has been renamed to avoid the conflict with the new AudioAnalyzer module of the Engine)

1.04 2019-05-17
FixedFixed special characters encoding of friendly device names, no more strange chars in audio device names
AddedAdded GetInputAudioDevices, this node returns a list with input devices
ChangedRenamed GetAudioDeviceNames to GetOutputAudioDevices
audio_device_selection
AddedAdded 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
doc_loopback_init_bp
  • Get Default Device Loopback Audio
  • Set Default Device Loopback Audio
doc_loopback_init_bp_device
  • Start Loopback
  • Stop Loopback
  • Is Loopback Capturing
doc_loopback_init_bp
  • Get Loopback Capture Time
doc_loopback_controls_bp_time
More detailed info into Documentation page
AddedAdded new Example project: Loopback Test
1.031 2019-04-20
FixedFixed crash with some MP3 formats
FixedFixed crash on Android start
1.03 2019-04-18
UpdatedSDL2 library updated to 2.0.9
AddedAdded mp3 format support on Win64 and Android Platforms
AddedAdded ID3 tags support v1 and v2
metatag_node
AddedAdded Format Test UE4 Project [UE4 Sample Projects]
ChangedChanged GetFolderFiles to Impure function to avoid extra calls, now must be explicitly executed by connecting exec wires
new_getfolderfiles
AddedAdded 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
new_playex_options
AddedAdded 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
new_audiodevice
More detailed info into Documentation page
1.02 2019-03-12
FixedFixed crash on wrong sound path during Player Initialization
AddedAdded channel selection mode in visualizer initialization
channel_selection_mode_option
  • All in one: Accumulates all channels data into only one array
  • Select one: Returns only the channel specified in Channel option
channelselectoneopt
  • Split all: Returns each channel into one array. Use “By Channel” nodes to retrieve the results
AddedNew amplitude analysis configuration node. Now Amplitude analysis use the same node structure as frequency spectrum and beat tracking analysis. Initialization + Getter
ChangedRemoved GetAmplitude parameters
amplitudenodes
AddedAdded 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
bychannelnodes
ChangedChanged GetBeatTrackingVariance node, now calculates Average and Variance with the same node. If you only need the average result you can continue using GetBeatTrackingAverage node
beattrackingvariancenode
