聲音鍛造中的腳本

Question

我對聲音鍛造中的腳本完全陌生。我有要求混合2 .wav文件。

例如，1.wav文件與反轉 2.wav文件混合。 我需要得到最終的混合輸出文件的統計數據。

統計如最小採樣值，所有通道的最大采樣值。

下面我有代碼混合2 .wav文件。但第二個不是倒置的。

任何人都可以請幫我在C＃上面的腳本嗎？ 或者如果任何人都可以與標準API共享一個可用於聲音僞造腳本的文檔，這也會有所幫助。

public class EntryPoint 
{ 
public void Begin(IScriptableApp app) 
{ 
//choose the first file. 
OpenFileDialog openFile = new OpenFileDialog(); 

     openFile.Title = "Open the input file."; 

     String inputFilePath = String.Empty; 

     if (openFile.ShowDialog() == DialogResult.OK) 
     { 
      inputFilePath = openFile.FileName.ToString(); 
     } 


     OpenFileDialog openOutputFile = new OpenFileDialog(); 

     openOutputFile.Title = "Open the output file."; 

     String outputFilePath = String.Empty; 

    if (openOutputFile.ShowDialog() == DialogResult.OK) 
    { 
     outputFilePath = openOutputFile.FileName.ToString(); 
    } 

    ISfFileHost backFile = app.OpenFile(outputFilePath, true, false); 
    ISfFileHost file = app.OpenFile(inputFilePath, false, false); 

    long fileLen = file.Length; 
    SfAudioSelection asel = new SfAudioSelection(file); 
    file.DoMixReplace(SfAudioSelection.All, 1, 1, backFile, new SfAudioSelection(0, file.Length), null, null, EffectOptions.EffectOnly | EffectOptions.WaitForDoneOrCancel); 


backFile.Close(CloseOptions.DiscardChanges); 

}

Answer 1

使用下面的代碼可以達到要求。

要求是： 1.wav文件與INVERTED 2.wav文件混合使用。獲取生成的混合輸出文件的統計信息。

統計如最小採樣值，所有通道的最大采樣值。
