    Hi. I have a large number of audio files and I want to change the import settings for all of them.I did some searches on how to do this but I had no luck I found this one post

    http://forum.unity3d.com/threads/46398-Batch-audio-clip-import-settings-modifier?highlight=AudioImporter

    but it doesn't seem to work with 3.2. They must have changed something

    this line shows an an error in 3.2

    Code (csharp):
    1. AudioImporter audioImporter = AssetImporter.GetAtPath(path) as AudioImporter;
    Any ideas on how to get this to work?

    Thanks

    Hi, they have changed some things. Try this fast-modified version:

    Code (csharp):
    1.  
    2.  
    3. using UnityEngine;
    4. using UnityEditor;
    5.  
    6. // /////////////////////////////////////////////////////////////////////////////////////////////////////////
    7. //
    8. // Batch audio import settings modifier.
    9. //
    10. // Modifies all selected audio clips in the project window and applies the requested modification on the
    11. // audio clips. Idea was to have the same choices for multiple files as you would have if you open the
    12. // import settings of a single audio clip. Put this into Assets/Editor and once compiled by Unity you find
    13. // the new functionality in Custom -> Sound. Enjoy! :-)
    14. //
    15. // April 2010. Based on Martin Schultz's texture import settings batch modifier.

    worked perfectly for me. I was using this to turn off 3D sound for about 300 files. Just saved me an hour :)

    I am doing a children's book with about 1500 files in 30 folders, this script saved me about 4 hours!

    I needed to change settings on all of them.

    Thank you!

    This was a great help Kiles!

    One small improvement that could be made is checking to see whether the asset actually changed before Re-Importing it.

    For example:

    Code (csharp):
    1.  
    2.     static void SelectedToggle3DSoundSettings(bool enabled) {
    3.  
    4.         Object[] audioclips = GetSelectedAudioclips();
    5.         Selection.objects = new Object[0];
    6.         foreach (AudioClip audioclip in audioclips) {
    7.             string path = AssetDatabase.GetAssetPath(audioclip);
    8.             AudioImporter audioImporter = AssetImporter.GetAtPath(path) as AudioImporter;
    9.             audioImporter.threeD = enabled;
    10.             AssetDatabase.ImportAsset(path);
    11.         }
    12.     }
    13.  
    to


    Code (csharp):
    1.  
    2.     static void SelectedToggle3DSoundSettings(bool enabled) {
    3.  
    4.         Object[] audioclips = GetSelectedAudioclips();
    5.         Selection.objects = new Object[0];
    6.         foreach (AudioClip audioclip in audioclips) {
    7.             string path = AssetDatabase.GetAssetPath(audioclip);
    8.             AudioImporter audioImporter = AssetImporter.GetAtPath(path) as AudioImporter;
    9.             if(audioImporter.threeD != enabled)
    10.             {
    11.                  audioImporter.threeD = enabled;
    12.                  AssetDatabase.ImportAsset(path);
    13.             }
    14.         }
    15.     }
    16.  
    Thanks again!

    Thanks a lot! I just wanted to find out how to write such a script myself when I stumbled upon this, so this saved me quite a lot of time.

    Unity 4 question:

    Hi, I dont know if its a noob one, but I have a question about this script and a related use.

    I want to record a clip using Microphone and save it to my project resource folder, so that I can then load it into an AudioClip and play it. The problem is that i want 3d to be disabled while importing it for playback, also I cant seem to understand how I could use this script even if i want to manually disable 3d for multiple files. Any help?

    Thanks

    Nice script. This should be present as natural options of Unity Editor...

    I love this script, I use it daily.

    I used to have a similar one that had a visual interface I could dock in the inspector, but I can't find that one anywhere now. I don't know what it would involve technically, but I wonder if this one could be modified to support that, rather than having to go through nested menus?

    Love intuitive design? Hate Cluttered Unneeded MenuItems? Want this tool to feel more like Unity Native Multiple selected items?

    Me too! So I made it happen. This version gets rid of the menu at the top and instead makes it so when you select two audio clips in the project folder - Bam! The audio settings are right there in the inspector! Lovely. :) Change the settings to what you need and hit apply to change all the audio.

    My version is not perfect and I'm sure it can be taken further but I'd need some help:
    1. Anyone know how to get it to properly show your multiple clips defaults and mixed settings
    2. How do you grey out features that should be not selectable?
    3. One or two of these buttons don't do anything yet. Anyone know how to get them working?
    This only works in Unity 4.6. Feel free to try it elsewhere but get rid of the "&& UNITY_4_6" part of the first line in my script.

    To make this work just Use my modified ChangeAudioImportSettings.cs and add the AudioClipEditor.cs class into the same Editor folder. Have at it:

    Code (CSharp):
    1.  
    2. using UnityEngine;
    3. using UnityEditor;
    4.  
    5. // /////////////////////////////////////////////////////////////////////////////////////////////////////////
    6. //
    7. // Batch audio import settings modifier.
    8. //
    9. // Modifies all selected audio clips in the project window and applies the requested modification on the
    10. // audio clips. Idea was to have the same choices for multiple files as you would have if you open the
    11. // import settings of a single audio clip. Put this into Assets/Editor and once compiled by Unity you find
    12. // the new functionality in Custom -> Sound. Enjoy! :-)
    13. //
    14. // April 2010. Based on Martin Schultz's texture import settings batch modifier.
    15. //
