audio - Applescript:导出 QuickTime 录音

Question

使用以下苹果脚本，我尝试

1. 使用“QuickTime Player”录制音频几秒钟

2. 导出轨道并将其保存到桌面

   tell application "QuickTime Player"
     launch
   
     set doku to new audio recording
     start doku
     delay 4
     stop doku
     set savePath to "~/Desktop/record.mp3"
     set newDoc to last item of (documents whose name contains "Untitled")
     export newDoc in file savePath using settings preset "Audio Only"
   
   end tell
   

创建新的录音似乎很容易，但由于某种原因导出命令不起作用。错误消息显示，我没有导出它的权限。

Answer 1

这似乎确实是一个沙箱问题，但如果您将文件路径引用从 QuickTime Player block 移到 Finder block 中，它就会起作用。另外，您的文件名应以“.m4a”而不是“.mp3”结尾，因为 QuickTime Player 创建 MP4 音频文件(文件扩展名“.m4a”)而不是 MP3 音频文件(文件扩展名“.mp3”)。

所以这个版本的脚本可以工作:

tell application "Finder"
    set savePath to (the path to the desktop folder as text) & "record.m4a"
    tell application "QuickTime Player"
        activate
        set doku to new audio recording
        start doku
        delay 4
        stop doku
        set newDoc to last item of (documents whose name contains "Untitled")
        export newDoc in file savePath using settings preset "Audio Only"
    end tell
end tell
