I guess this SDK can be import as C++ dll in C# script? like Dllimport[...], or add dll in plugin folder? but this repo is like a project? how to install this SDK? download this repo and copy to unity projects？ don't get it..

basic question, hope get the answer...

This commit:

Changed the lines from:
atk = GetTimeConstant(0.99f, _atk); rel = GetTimeConstant(0.99f, _rel);
to:
atk = GetTimeConstant(0.99f, atk); rel = GetTimeConstant(0.99f, rel);

which means atk and rel are never being set correctly.

Problem:
We are shipping commercial audio plugin and we would like to hide symbols of internal components. However, the UNITY_AUDIODSP_EXPORT_API macro does not force visibility so we ended up hiding UnityGetAudioEffectDefinitions symbol as well, resulting in Unity can't find our audio plugin on android.

To reproduce:

1. Download AudioPluginInterface.h
2. Make some simple audio plugin (maybe a gain knob?)
3. Using Cmake, compile it as a android .so with following flags: -fvisibility=hidden -fvisibility-inlines-hidden
4. In Unity, build an Android game using your audio plugin, and install it on your android device
5. Open up Android logcat on PC/Mac, and record out-comming log
6. Run your game on Android device, you should experience that the audio plugin you made didn't do anything
7. Stop Android Logcat, search for your plugin name in the recorded log, you should be able to find errors saying your plugin could not be found.

Proposed fix:
Inside AudioPluginInterface.h, change

#if PLATFORM_WIN
#define UNITY_AUDIODSP_EXPORT_API __declspec(dllexport)
#else
#define UNITY_AUDIODSP_EXPORT_API
#endif

to this:

#if PLATFORM_WIN
#define UNITY_AUDIODSP_EXPORT_API __declspec(dllexport)
#else
#define UNITY_AUDIODSP_EXPORT_API attribute((visibility("default")))
#endif

Hope this got fixed soon.

• Problem

  • Build - fail log

• Env

  • Unity (2021.3.3f1) - windwos build

• Build Log - Fail

C:\Users\user01\Desktop\$AS\audiostream_development\AudioPlugin\AudioPluginUtil.cpp(491): Unit test 'Accuracy' failed for expression 'err < errtol'.
C:\Users\user01\Desktop\$AS\audiostream_development\AudioPlugin\AudioPluginUtil.cpp(488): Unit test 'Accuracy' failed for expression 'err < errtol'.

I want to use these effects on Android, but this can be used only on the computer！

Summary

With two or more plug-in instances active in an AudioMixer (e.g. in two Groups), the Custom GUI won't reflect the plug-in parameter's state after a parameter has been set via the Custom GUI's script. It only shows the last set value independent of the plug-in instance.

In code words:

after calling

plugin.SetFloatParameter("parameterName", value);

in IAudioEffectPluginGUI's OnGUI(IAudioEffectPlugin plugin) method,

plugin.GetFloatParameter("parameterName", out float value);

always returns the value which was set most recently, independent on which plugin instance is currently selected.

Steps to reproduce

• Clone / download the latest version of this repository
• build the project in NativeCode
• create a new Unity project
• import the binary (e.g. AudioPluginDemo.bundle on macOS) into the projects (assets)
• also import EqualizerCustomGUI.cs, GUIHelpers.cs, MathHelpers.cs from GUICode/AudioPluginDemoGUI
• create an AudioMixer
• create a new Group
• add the Demo Equalizer plugin in both groups (Master and the new one)
• move the sliders of LowFreq, MidFreq, and HighFreq in one of the instances (only sliders, NOT the editor)
• switch back and forth between both plugins and verify that the state updates accordingly
• move one of the vertical bars (black, grey, white) of one instances, see how the corresponding frequency slider changes (expected behaviour)
• again: switch back and forth between the plugins, see that the rendered GUI won't update any more although the Horizontal Sliders do

I don't think this is a bug of this repository, but rather one in Unity itself. Or is there something you can do in the scripts to prevent this from happening?

This behaviour renders the CustomGUI feature unusable if the GUI is used to change parameter values and not only displays them (like in all the UI examples in this repository).

I am getting this when building: unsealed contents present in the bundle root
Command CodeSign failed with a nonzero exit code
