Set/get the way Unity is loading the Audio data.

	// C#: If an imported audio contains the "DL_" string
	// in its filename, it sets the loadType to DecompressOnLoad.
	class MyAudioPostprocessor extends AssetPostprocessor {
		function OnPreprocessAudio () {
			if (assetPath.Contains("DL_")) {
				var audioImporter : AudioImporter = assetImporter;
				audioImporter.loadType = AudioImporterLoadType.DecompressOnLoad;
