Invalid Wave file RIFF header when recording with a microphone

[eugeneYz]

I used Naudio to capture microphone audio data and converted (byte [] type) pcmData to WaveStream, but processor.ProcessAsync (waveStream) still reported an error. How can I fixed it up?

            nAudioHelper?.StartRec();
            nAudioHelper.PcmDataAvailable += async (data) =>
            {
                pcmData = data;
                MemoryStream memoryStream = new MemoryStream(pcmData);

                WaveFormat waveFormat = new WaveFormat(16000, 16, 1); 

                WaveStream waveStream = new RawSourceWaveStream(memoryStream, waveFormat);
                await foreach (var result in processor.ProcessAsync(waveStream))
                {
                    numkeyboard.Value = result.Text;
                }
            };
            nAudioHelper?.StopRec();

The wavestream that was provided was not containing the wave header and this caused the processor to not accept it as it doesn't know how to decode it (what's the frequency, etc).
