C# 在Windows Phone 8.1应用程序中使用Accord音频库(非Silverlight)
我目前正在使用C#为Windows Phone 8.1构建一个应用程序 该应用程序的目的是评估来自设备麦克风的音频信号,最初是频率 我本来希望使用Accord库来帮助解决这个问题,但遇到了以下错误: XamlCompiler错误WMC1006:无法解析程序集或Windows 元数据文件“System.Windows.Forms.dll” \程序文件 (x86)\MSBuild\Microsoft\WindowsXaml\v12.0\8.1\Microsoft.Windows.UI.Xaml.Common.targets(327,9): Xaml内部错误WMC9999:无法解析类型universe 程序集:System.Windows.Forms,版本=4.0.0.0,区域性=中性, PublicKeyToken=b77a5c561934e089 我相当肯定,这是由于项目中包含的参考资料引起的,但我不确定 这是我目前的代码:C# 在Windows Phone 8.1应用程序中使用Accord音频库(非Silverlight),c#,audio,windows-phone-8.1,fft,accord.net,C#,Audio,Windows Phone 8.1,Fft,Accord.net,我目前正在使用C#为Windows Phone 8.1构建一个应用程序 该应用程序的目的是评估来自设备麦克风的音频信号,最初是频率 我本来希望使用Accord库来帮助解决这个问题,但遇到了以下错误: XamlCompiler错误WMC1006:无法解析程序集或Windows 元数据文件“System.Windows.Forms.dll” \程序文件 (x86)\MSBuild\Microsoft\WindowsXaml\v12.0\8.1\Microsoft.Windows.UI.Xaml.Co

我们将非常感谢在解决这些错误方面提供的任何帮助或指导
谢谢除了.NET之外,其他平台无法访问原始的Accord.NET框架
通过可移植类库将Accord.NET移植到移动平台是一项努力(我负责这项工作)。其中一些软件包也在NuGet上发布(前缀为Portable Accord)
该音频包未在NuGet上发布,但您应该能够从Windows Phone 8.1的源代码构建它。你可以找到便携式雅阁的来源
请注意,仅支持播放,不支持录制
