New Post: Ima Adpcm Error during Compression

Ya,i tried the way you said.but still i am getting the same error .

public  ImaAdpcmWaveFormat(int sampleRate, int channels, int bitsPerSample,int sperblock) 

      {     

         this.waveFormatTag = WaveFormatEncoding.DviAdpcm; // can also be ImaAdpcm - they are the same 

          this.sampleRate = sampleRate; 

          this.channels = (short)channels; 

          this.bitsPerSample = (short)bitsPerSample; // TODO: can be 3 or 4   

          this.extraSize = 2;//    

          this.blockAlign = 256; //TODO       

          this.averageBytesPerSecond = 4055; //TODO     

          this.samplesPerBlock = (short)sperblock; // TODO                   

}

Above values which i am assigning are same as  NaudioDemo Application values.

   Format 0: 8.000 kHz, 4 Bit, Mono      FormatTag: DviAdpcm, Support Flags: Codec      WaveFormat: DviAdpcm 8000Hz Channels: 1 Bits: 4 Block Align: 256,     AverageBytesPerSecond: 4055 (32.4 kbps), Extra Size: 2      Extra Bytes:      F9 01 

In my code i wrote like this,

 convertedStream = New WaveFormatConversionStream(New ImaAdpcmWaveFormat(8000, 1, 4, 2048), Reader)                     WaveFileWriter.CreateWaveFile(CurrentFile, convertedStream)

Since Extra Bytes in Hexa Decimal,i converted it into Decimal.
