Exactly. Thank you for the example.
You can obtain this effect using the average frequency values of Get Spectrum node
On each Tick Event, take only the average values greater than the current maxAverageValue for each bar, update the bar objects, and apply a decay to all values to obtain the falling effect.
Is it can calculate frequencies and amplitude only realtime? can it calculate if audio not playing, calculation in separate second? And another question: can it calculate frequencies and amplitudes in separate range?
You can obtain the analysis at specific time position using Set Playback Position + Get Amplitude / Get Spectrum nodes instead of a Play node.
To define a custom range of the frequency analysis yuo must use the Init Spectrum Config WLimits node instead of the Init Spectrum Config node.
You can set the low and high frecuency bound of the analysis bands. You only have two rules to make this list: sorted and no overlap.
So an example of valid bounds array:
0-10
11-40
80-100
And an example of invalid bounds array:
0-10
10-40 (overlap frequency 10Hz)
0-10
5-40 (overlap frequencies 5-10Hz)
Thanks a lot!!! It’s Working
Hello! I want to say thank you for this plugin, its really usefull, but i have few questions.
First of all, what does ‘total bpm’ returns? Most of the time it returns zero for me for each frequency (low, high and bass);
Second question is more about using this plugin plus music theory. How can i get total average bpm for whole track?
Each time you call GetBeatTrackingxxxx node the analysis is calculated for a window of time centered in the current playback time of the audio, this calculates the bpm value for the actual window (Current BPM). So, if you call it multiple times you obtain the bpm results of a lot of windows during the song.
The Total BPM counter returns the bpm value that occur most often during all the song. (The most repeated Current BPM value of all the windows).
If the song has too many “silences” for the analysis band then it can result it can increase the number of windows with a BPM value of 0, positioning the bpm-zero value as the most used by the song in that band.
You can calculate the Current BPM in different positions of the song and take the average, but in my oppinion the most repeated BPM is more exact than the average BPM.
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
More detailed info into Documentation page](https://www.parallelcube.com/content/docs/audioanalyzer/blueprint_page.html)
– Added new Example project: Loopback Test
Am I missing something obvious, in the example projects for AA where are the audio initializer parameters at? I don’t understand how the AA_StarterProject picks up the sample.wav file. I’m trying to integrate the plugin into my project but I can’t find the classes like **Init Loopback Audio **when searching for them, the plugin is enabled in the plugin viewer.
**EDIT: **Found the Init parameters in the UI_InputSelector blueprint, StartPlayback function. Viewing the graph you can find the sample.wav file mentioned there. In order to find the Init parameter functions you need to create a blueprint based off of the AA class at the bottom when expanding all classes.

If you could make the documentation a bit more straightforward on how and where to initialize the classes that would be great. Having some documentation on your examples for how they’re built would also be much appreciated.
Sure, we have always wanted to modify the Projects section and fix the lack of documentation in the sample projects.
I’m not very happy with the Documentation page but work with doxygen is a pain.
Hi, I have the plugin set and working But IM not able to deploy to Android devices, is there any documentation on how to deploy and include the plugin in an android device?
You don’t have to do any special to include this plugin, just enable it in the plugin list.
If it is your first project android deploy you can look to this guidelines to install and setup the engine for android platform:
-
Install NDK ans Android SDK for your target android version
Installing CodeWorks for Android | Unreal Engine Documentation
Android Game Development | Unreal Engine Documentation -
Project setup
Android Quick Start | Unreal Engine Documentation -
Packaging for android platform
Packaging Android Projects | Unreal Engine Documentation
The Starter Project is ready for android platform, you can take a look to the Packaging Project section and Android to see how has been configured.
If you have any error, put the log in this post and we will try to find a solution.
2019-07-10 v1.051
– Added Ogg Vorbis Support
– Added Flac Support
– Fixed Android smoothness bug of some devices
2019-08-17 v1.06
– Added Get Spectrum Peaks. Now you can obtain a list with the most valued frequencies in real time.
– Added thridparty decoders inclusion customization. Now you can select which decoder binaries can be included in your project. More Details](Thirdparty libraries — AudioAnalyzer 2.09 documentation)
– Added installation and set-up tutorial from Empty Project [Link]](Blueprint Empty Project Sample — AudioAnalyzer 2.09 documentation)
– Added manual installation and support notes for unsupported Marketplace versions, 4.19 and Older [Link]](Installation — AudioAnalyzer 2.09 documentation)
Awesome plugin! I am very satisfied.
I have one question.
Oculus lift s in use.
The microphone input is also good.
However, when using the ‘Get Amplitude’ function
Only half the corresponding array values are included.
Do you have any idea why?
Please let me know if you need more information.
It’s a really good plugin.
It’s ok, this is because the plugin centers the wave data on the current playback position.
For example, if you want a window of 2 seconds you are taking 1 sec in the past and 1 sec in the future to see the current playback position centered.
When you are taking the audio data from microphone you can’t obtain the audio from the future, so this part has 0 value.
How do I get the “Full source C++ included”?
Go to the plugins folder of your installed engine and search for AudioAnalyzer. You will find a Source folder with all the C++ classes
{Installation_engine_path}\EpicGames\UE_4.2x\Engine\Plugins\Marketplace\AudioAnalyzer\Source
Thank you for the information and a quick response. Could you please tell me exactly which version of the UE4 that can run your audio analyzer projects without errors? Or is there a link where I can download audio analyzer projects suitable for UE4 version 4.22.3?
I have tried loading these into UE4 version 4.22.3 without success:
https://www.parallelcube.com/content/binaries/AudioAnalyzer/UE4_P_AATester_v1.04_2019-05-14.zip
https://www.parallelcube.com/content/binaries/AudioAnalyzer/AA_Loopback.zip
All projects must be run without errors for that version, can you send me the full log with the errors to support@paralllecube.com ?
