You can convert the short array back to a byte array:
short[] sampleData = ...
byte[] byteArray = new byte[sampleData.Length*2];
Buffer.BlockCopy(sampleData , 0, byteArray, 0, byteArray.Length);
Then you can create a wave stream using the WaveMemoryStream
class below - for that you will need to know the wave format of your sample data. This stream can then i.e be saved as a WAV file or played back by SoundPlayer
.
public class WaveMemoryStream : Stream
{
public override bool CanSeek { get { return false; } }
public override bool CanWrite { get { return false; } }
public override bool CanRead { get { return true; } }
public override long Length { get { return _waveStream.Length; } }
public override long Position { get { return _waveStream.Position; } set { _waveStream.Position = value; } }
private MemoryStream _waveStream;
public WaveMemoryStream(byte[] sampleData, int audioSampleRate, ushort audioBitsPerSample, ushort audioChannels)
{
_waveStream = new MemoryStream();
WriteHeader(_waveStream, sampleData.Length, audioSampleRate, audioBitsPerSample, audioChannels);
WriteSamples(_waveStream, sampleData);
_waveStream.Position = 0;
}
public void WriteHeader(Stream stream, int length, int audioSampleRate, ushort audioBitsPerSample, ushort audioChannels)
{
BinaryWriter bw = new BinaryWriter(stream);
bw.Write(new char[4] { 'R', 'I', 'F', 'F' });
int fileSize = 36 + length;
bw.Write(fileSize);
bw.Write(new char[8] { 'W', 'A', 'V', 'E', 'f', 'm', 't', ' ' });
bw.Write((int)16);
bw.Write((short)1);
bw.Write((short)audioChannels);
bw.Write(audioSampleRate);
bw.Write((int)(audioSampleRate * ((audioBitsPerSample * audioChannels) / 8)));
bw.Write((short)((audioBitsPerSample * audioChannels) / 8));
bw.Write((short)audioBitsPerSample);
bw.Write(new char[4] { 'd', 'a', 't', 'a' });
bw.Write(length);
}

{

bw.Write(sampleData, 0, sampleData.Length);
