需求:需要对音频做出修改,压缩音频质量,检测是否设置为Mono与Normalize,
超过10秒LoadType设为Streaming.
思路:遍历所有的音频文件,拿到所有的音频文件对象，针对不同平台的音频文件做修改。
1.遍历所有的文件夹
string projectPath = Application.dataPath; //获取Assets的路径
allAudioFile.Clear();
projectPath = projectPath.Substring(0,projectPath.IndexOf("Assets"));
try
{
GetAudiosPath(projectPath,FilePath,"AudioClip",ref allAudioFile); //这是一个封装的方法
}
//获取所有的音频文件的path信息
public static void GetAudiosPath(string projectPath,string targetFilePath,string searchType,ref List<string> array)
{
if (Directory.Exists(targetFilePath))
{
string[] guids;
//搜索
guids = AssetDatabase.FindAssets("t:" + searchType, new[] { targetFilePath }); //查到 targetFilePath路径下的这个searchType的guid
foreach (string guid in guids)
{
string source = AssetDatabase.GUIDToAssetPath(guid); //根据guid查找路径
string[] allStr = source.Split('.');
if(source.EndsWith(".ogg")|| source.EndsWith(".mp3") || source.EndsWith(".wav") || source.EndsWith(".aif")) //过滤音频文件
{
allAudioFile.Add(source); //所有的音频文件
}
}
}
}
2.[MenuItem("Assets/xxxx")] 这个是插件，这个功能放在了Assets下面。这句话需要卸载函数上面，且这个函数必须是静态函数

3.核心代码AudioImporterSampleSettings 这个能拿到不同平台上的Audio的对象
4.OnGUI() 查找到之后需要做一个显示的界面,一遍快速的定位到，是否真的修改成功了。
后期改进,不需要改进的的加个过滤,可以提高效率

修改后，还需要代码重新导入才能生效
