玩聲音窗口時發出噪音手機7模擬器

Question

我有一個.wav音樂文件。 當我試圖播放使用SoundEffect.Play（）;

mus1.Play（）;我得到的是噪音而不是音樂。 在PC音樂播放器中播放效果也很好。 如何解決此問題？

如何確保它能在Windows Phone 7中發揮出色呢？

Answer 1

這聽起來像WP7不理解.wav文件中的內容。爲什麼不嘗試將它轉換爲.wav（是的，我知道它已經在.wav中），因爲這可能會刪除未知數據。

Audacity（http://audacity.sourceforge.net/）是免費的，將爲您做到這一點。只需將.wav文件拖入其中，然後單擊文件 - >導出...

試試下面的代碼

MainPage.xaml.cs中

namespace MediaSample 
{ 
    public partial class MainPage : PhoneApplicationPage 
    { 
     // Constructor 
     public MainPage() 
     { 
      InitializeComponent(); 
      progress.DataContext = this; 
      this.Loaded += new System.Windows.RoutedEventHandler(MainPage_Loaded); 
      mediaplayer.BufferingProgressChanged += new System.Windows.RoutedEventHandler(mediaplayer_BufferingProgressChanged); 
      mediaplayer.CurrentStateChanged += new RoutedEventHandler(mediaplayer_CurrentStateChanged); 
     } 

     public double Duration { get; set; } 

     void mediaplayer_CurrentStateChanged(object sender, RoutedEventArgs e) 
     { 
      if (mediaplayer.CurrentState == MediaElementState.Playing) 
      { 
       Duration = mediaplayer.NaturalDuration.TimeSpan.TotalSeconds; 
       ThreadPool.QueueUserWorkItem(o => 
       { 
        while (true) 
        { 
         Dispatcher.BeginInvoke(new Action(() => Progress = mediaplayer.Position.TotalSeconds * 100/Duration)); 
         Thread.Sleep(0); 
        } 
       }); 
      } 
     } 

     void mediaplayer_BufferingProgressChanged(object sender, System.Windows.RoutedEventArgs e) 
     { 
      MediaElement mediaplayer = sender as MediaElement; 
      if (mediaplayer.BufferingProgress == 1) 
       Debug.WriteLine(mediaplayer.NaturalDuration); 
     } 

     void MainPage_Loaded(object sender, System.Windows.RoutedEventArgs e) 
     { 
      mediaplayer.Source = new Uri("/Oru nalum..mp3", UriKind.Relative); 
      mediaplayer.Play(); 
     } 



     public double Progress 
     { 
      get { return (double)GetValue(ProgressProperty); } 
      set { SetValue(ProgressProperty, value); } 
     } 

     // Using a DependencyProperty as the backing store for Progress. This enables animation, styling, binding, etc... 
     public static readonly DependencyProperty ProgressProperty = 
      DependencyProperty.Register("Progress", typeof(double), typeof(PhoneApplicationPage), new PropertyMetadata(0.0)); 



    } 
} 

MainPage.xaml中

<phone:PhoneApplicationPage 
    x:Class="MediaSample.MainPage" 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
    xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone" 
    xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone" 
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
    mc:Ignorable="d" d:DesignWidth="480" d:DesignHeight="768" 
    FontFamily="{StaticResource PhoneFontFamilyNormal}" 
    FontSize="{StaticResource PhoneFontSizeNormal}" 
    Foreground="{StaticResource PhoneForegroundBrush}" 
    SupportedOrientations="Portrait" Orientation="Portrait" 
    shell:SystemTray.IsVisible="True"> 

    <Grid x:Name="LayoutRoot" Background="Transparent"> 
     <Grid.RowDefinitions> 
      <RowDefinition Height="Auto"/> 
      <RowDefinition Height="*"/> 
     </Grid.RowDefinitions> 

     <StackPanel x:Name="TitlePanel" Grid.Row="0" Margin="12,17,0,28"> 
      <TextBlock x:Name="ApplicationTitle" Text="Media Application" Style="{StaticResource PhoneTextNormalStyle}"/> 
     </StackPanel>   

     <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0"> 
      <MediaElement x:Name="mediaplayer"/> 
      <ProgressBar Height="40" x:Name="progress" Value="{Binding Path=Progress}"/> 
     </Grid> 
    </Grid> 


</phone:PhoneApplicationPage> 

外接MP3文件，如下所示，

一樣，你可以添加.wav文件。運作良好。上面的測試代碼。 謝謝。

使用MeadiaElement而不是使用SoundEffect類。 試試這個 MediaElement
