Audio SDK - Convolution Reverb - How to Use Custom Samples/Impulse Responses

I'm new to Unity and am trying to familiarize myself with the Audio SDK as part of my research on spatial audio and convolution. Can someone please help me understand how to load my own impulse response (IR) into the demo convolution reverb plugin?

I see C++ functionality to upload an IR in Plugin_ConvolutionReverb.cpp:



And the C# ConvolutionReverbCustomGUI.cs file declares a GetSampleName function on line 8:




Should I be writing additional code within the .cpp file to read an audio file of my choice (using e.g. a library like libsndfile) and manually enter all of the necessary parameters in the code? Or am I perhaps missing something obvious that will enable me to choose an IR file using the included Convolution Reverb GUI? I see a "Use Sample" parameter, but I can't figure out how to actually specify/upload the sample(s) in the first place.




Any and all help would be greatly appreciated!

 

So I managed to put in my own artificial IR (a simple sine wave) by...

...declaring the ConvolutionReverbCopy_UploadSample function that's specified at the bottom of the plugin code


...so that I could use the function directly farther down in the CreateCallback function


...and the sample shows up as I had hoped in the plugin GUI in Unity



However, I'm still wondering if there's some sort of built-in GUI that let's me do the same thing (i.e. upload my own impulse responses). Since I'm neither familiar with C# nor with Unity scripting in general, I would really appreciate either finding out where I can easily specify files to upload or a starting point for some simple GUI code that can achieve the same thing.

 

This is extremely helpful thank you! But I still don't quite understand where to declare the ConvolutionReverb_UploadSample. Also how can I upload a sound file of a recorded impulse response? I have absolutely no experience with C++ so i'm struggling to find the appropriate way to do this.

 

Disregard.. I realised there is a C# Script in Assets/Scripts called "ConvolutionReverbUploadIR" that basically does it for you.

 

Hi there,
I'm struggling to see where/how you upload a recorded impulse response in the ConvolutionReverbUploadIR script. Would anyone be able to give me advice on this please?

 

I know this is a suuuuper old topic but Is the convolution plugin still available, i cant find it in the plugins list

 

Yes it its.
