Question

我使用下面的代码来混合波形文件

它指出错误＆＃39;无法找到类型或命名空间MixingSampleProvider＆＃39;。我已经添加了Naudio的参考并使用了

 void Mixingfunction(List<string> inputFiles)
    {
        MixingSampleProvider mixer = new MixingSampleProvider(NAudio.Wave.WaveFormat.CreateIeeeFloatWaveFormat(44100, 1));
        try
        {

            for (int y = 0; y < counter; y++)
            {
                audioFileReader = new AudioFileReader(inputFiles[y]);
                mixer.AddMixerInput((ISampleProvider)audioFileReader);
            }
        }
        catch (Exception e)
        {
            MessageBox.Show(e.Message);
            return;

        }

        if (flag == true)
        {
            mixer.AddMixerInput((ISampleProvider)sineWaveProvider);
        }
        SampleToWaveProvider mixer2 = new SampleToWaveProvider(mixer);
        waveout.Init(mixer2);
        waveout.Play();
    }

使用using NAudio; using NAudio.Wave; using NAudio.Wave.SampleProviders;解决WaveIn相同的问题。那么NAudio.Wave.WaveIn的父层次结构是什么。

Answer 1

它在int width = 225; int height = 160; int size = width * height; int[] pixelData = new byte[size]; for (int i = 0; i < size; i++) { // pack 4 bytes into int for ARGB_8888 pixelData[i] = ((0xFF & (byte)255) << 24) // alpha, 8 bits | ((0xFF & (byte)255) << 16) // red, 8 bits | ((0xFF & (byte)0) << 8) // green, 8 bits | (0xFF & (byte)0); // blue, 8 bits } Bitmap image = Bitmap.createBitmap(pixelData, width, height, Bitmap.Config.ARGB_8888);因此请确保您使用的是最新的NAudio（1.7.3）

什么是MixingSampleProvider NAudio的父层次结构
