C＃壓縮WAV PCM到Microsoft GSM 6.10音頻編解碼器

Question

是否有人知道如何將PCM格式的未壓縮波形文件轉換爲GSM 6.10音頻編解碼器中壓縮的wav文件？

Answer 1

IIRC，如果您已經安裝了編解碼器，naudio應該能夠與它使用WaveFormatConversionStream

Answer 2

試用，我現在有一個支持票出了問題我How to convert to Gsm Wav file

static void ToWavWithGsm() 
    { 
     string fileName = @"e:\Down\male.wav"; 
     WaveReader wr = new WaveReader(File.OpenRead(fileName)); 
     IntPtr format = wr.ReadFormat(); 
     IntPtr formatGsm = AudioCompressionManager.GetCompatibleFormat(format, 
      AudioCompressionManager.Gsm610FormatTag); 
     byte[] dataGsm = AudioCompressionManager.ToFormat(wr, formatGsm); 
     WaveWriter ww = new WaveWriter(File.Create(fileName + ".wav"), 
      AudioCompressionManager.FormatBytes(formatGsm)); 
     ww.WriteData(dataGsm); 
     ww.Close(); 
     wr.Close(); 
    }
