Bug in Unity? Importing / Compressing a lot of (huge) Audio Files hangs / freezes

Hi,

Reason for this post: I think i found a serios bug in Unity 3.4 Pro Importer.

if you import a lot of Ogg-Files Unity will freeze/hang after a while. The first x files get compressed as expected but then it slows down until complete freeze.

I thought its a problem related to ogg-files - but nah nah! Its the importer! I replaced all OGG-Files with WAV-Files and scripted a "set all AudioFiles to compressed and reimport it" - and guess what: Same issue here. First wav-files get imported / converted but then slows down until full freeze.

Here is the script I use (but you could also just paste a lot of OGG files to you project)

ReimportAllAudioFiles.cs Editor Script (c#) so you could force all audiofiles in a directory to reimport.

Code (csharp):

1.  
2. using UnityEngine;
3. using UnityEditor;
4.  
5. using System.Collections;
6. using System.IO;
7.  
8. public class ReimportAllAudioFiles : ScriptableObject
9. {
10.     [MenuItem ("Custom/Audio/ReimportWav")]
11.     protected static void ReimportAllAudio ()
12.     {
13.        
14.         string realPath = Application.dataPath;
15.         realPath = realPath.Remove( realPath.Length - 6 );
16.        
17.         string selectedPath = realPath + AssetDatabase.GetAssetPath( Selection.activeObject );    
18.        
19.         string [] fileEntries = Directory.GetFiles( selectedPath, "*.wav", SearchOption.AllDirectories );
20.        
21.         foreach (string file1 in fileEntries )
22.         {
23.             string file = file1.Replace( "\\", "/" );
24.             file = file.Remove( 0, realPath.Length );
25.             Debug.Log("AssetDatabase.ImportAsset("+file+");");
26.             AssetDatabase.ImportAsset( file );
27.         }
28.  
29.     }
30.  
31.    
32. }
33.  
34.  

and NewAudioSettings.js to setup all audio import properties when a AudioAsset gets imported.

Code (csharp):

1.  
2. class NewAudioSettings extends AssetPostprocessor
3. {
4.     function OnPreprocessAudio ()
5.     {
6.         var audioImporter : AudioImporter = assetImporter;
7.        
8.         Debug.Log("My Asset Post Processing " + audioImporter.assetPath);
9.  
10.         if ( audioImporter.format != AudioImporterFormat.Compressed )
11.         {
12.             audioImporter.threeD = false;
13.             audioImporter.compressionBitrate = 128000;
14.             audioImporter.format = AudioImporterFormat.Compressed;
15.             audioImporter.loopable = true;
16.         }
17.         else
18.         {
19.             Debug.Log("Asset already compressed");
20.         }
21.        
22.     }
23. }
24.  

here is the list of files with size description I use in that unity iOS Project. I use Unity 3.4 Pro for iOS on a Mac Pro i7 Dual Core (12 virtual CPU Threads), 8GByte Ram, OS is Lion

Code (csharp):

1.  

TOTAL 207 Files about 436.636.814 Bytes

So - i think this is a serios bug in Unity - may be only in the Mac Version - don't know. Is there any solution for that bug? Is there a possibility to report such bugs?

 

Bug Reporting - in the help menu the bug reporter

 

Bug confirming: you are at the right place. Is somebody able to repeat?

 

I encountered that this bug is only on Macs - may be just my mac or may be just Mac with Lion. The PC will just do it fine. I could maybe create a sample project to demonstrate that bug. Will post that tomorrow since Im kind of busy right now.

I will test it on an older mac, too. And then posting again with sample project. Thank you for the quick response!

 

In Unity 2017.4.2 Mac OS Catalina Wav files are the issue. Unity Freezes while importing them

 

me too

 

Have you found an answer? Any solution?
I can not open project becuase of OGG files, they not gonna imported,
and asset importer menu is getting time but nothing is happening
