关于函数_SoundLength 的问题

_SoundLength
--------------------------------------------------------------------------------

返回声音文件的长度.


#include <Sound.au3>
_SoundLength ( $aSnd_id [, $iMode ] )


该函数好像返回数值不准确，不知大家是否也有该问题？

我这里正常,但是长度不到1秒的文件就当不存在.

#include <Sound.au3>

;open sound file : must be modified if run under Vista
$sound = _SoundOpen(@WindowsDir & "\media\Windows XP Startup.wav")
If @error = 2 Then
    MsgBox(0, "Error", "The file does not exist")
    Exit
ElseIf @extended <> 0 Then
    $extended = @extended ;assign because @extended will be set after DllCall
    $stText = DllStructCreate("char")
    $errorstring = DllCall("winmm.dll", "short", "mciGetErrorStringA", "str", $extended, "ptr", DllStructGetPtr($stText), "int", 128)
    MsgBox(0, "Error", "The open failed." & @CRLF & "Error Number: " & $extended & @CRLF & "Error Description: " & DllStructGetData($stText, 1) & @CRLF & "Please Note: The sound may still play correctly.")
Else
    MsgBox(0, "Success", "The file opened successfully")
EndIf
MsgBox(0, "Sound Length", "The Sound has a length of:" & @CRLF & "hh:mm:ss - " & _
      _SoundLength($sound, 1) & @CRLF & "Milliseconds - " & _SoundLength($sound, 2))

举个例子：

    千千静听显示时间

差距很大，不知是什么原因

希望大家帮下忙 谢了

lixiaolong 发表于 2010-12-8 21:10:41

5:33和4:04 那个是真正的时间？

    感觉千千静听的准点

thealert 发表于 2010-12-8 21:40:27

media player 也是4:04

lin0308 发表于 2010-12-9 14:15:35

我想应该是声音文件有问题.
看看其它文件怎么样.
