How to write NAudio WaveStream to a Memory Stream?

c#, naudio, stream

Solution

Give this a try:

using (WaveStream waveStream = WaveFormatConversionStream.CreatePcmStream(new Mp3FileReader(inputStream))) 
using (WaveFileWriter waveFileWriter = new WaveFileWriter(outputStream, waveStream.WaveFormat)) 
{ 
    byte[] bytes = new byte[waveStream.Length]; 
    waveStream.Position = 0;
    waveStream.Read(bytes, 0, waveStream.Length); 
    waveFileWriter.WriteData(bytes, 0, bytes.Length); 
    waveFileWriter.Flush(); 
}

Problem

I have a program that takes in mp3 data in a byte array. It has to convert that mp3 data into wav format and store it in a byte data. I am trying to use NAudio for this purpose. I am using the following code for this purpose. ``` Stream inputStream = ...; Stream outputStream = ...; using (WaveStream waveStream = WaveFormatConversionStream.CreatePcmStream(new Mp3FileReader(inputStream))) using (WaveFileWriter waveFileWriter = new WaveFileWriter(outputStream, waveStream.WaveFormat)) { byte[] bytes = new byte[waveStream.Length]; waveStream.Read(bytes, 0, waveStream.Length); waveFileWriter.WriteData(bytes, 0, bytes.Length); waveFileWriter.Flush(); } ``` When I run the above code, all I receive is 0 in the byte array. But if use WaveFileWriter to write the data directly to a file, the file receives the correct data. Any reasons?
