通过Skype电话发送音频

当我点击Windows窗体上的按钮时,我正在尝试发送音频文件(或通过当前输入设备直接播放Skype音频)。我发现了一些链接,但所有引用似乎都被打破了,我对如何使用它感到很生气。

我已经设法连接到skype api并使用它(我已经将它用于其他项目并且它运行良好),但我真的无法通过输入音频流发送任何音频。

任何建议都将受到赞赏。

看起来问题与文件格式有关,而不是我的代码应该有效。

这是我在skype论坛上得到的答案:http://devforum.skype.com/t5/Developer-Corner/Skype4COM-and-C-Sending-audio-on-current-call-through-input/td-p/8414?utm_source=Subsciption&utm_medium=Subsciption&utm_campaign=Subsciption

它有效,我将文件构建为16位样本,16khz,单声道WAV文件。 以下是使用System.Speech库的代码:( Speak是一个SpeechSynthesize对象)

    Speak.SetOutputToWaveFile(filepath, new System.Speech.AudioFormat.SpeechAudioFormatInfo(
        16000,
        System.Speech.AudioFormat.AudioBitsPerSample.Sixteen,
        System.Speech.AudioFormat.AudioChannel.Mono
    ));

希望这个帮助
