Received a frame with a sampling rate of 44100, in MP3 format with a sampling rate of 48000. Mp3FileReader does not support changing the sampling rate
I am using NAudio in my Wpf app for the first time.
Steps: 1) Writing to MemoryStream using NAudio (C #, Wpf). This is my writing code:
public void StartRecording()
{
this.waveSource = new WaveIn();
if (Stream == null)
{
Stream = new MemoryStream();
}
waveSource.WaveFormat = new WaveFormat(44100, 2);
this.waveFile = new WaveFileWriter(this.Stream, this.waveSource.WaveFormat);
this.waveSource.DataAvailable += new EventHandler<WaveInEventArgs>(waveSource_DataAvailable);
this.waveSource.RecordingStopped += new EventHandler<StoppedEventArgs>(waveSource_RecordingStopped);
this.waveSource.StartRecording();
}
private void waveSource_DataAvailable(object sender, WaveInEventArgs e)
{
if (waveFile != null)
{
waveFile.Write(e.Buffer, 0, e.BytesRecorded);
int secondsRecorded = (int)(waveFile.Length / waveFile.WaveFormat.AverageBytesPerSecond);
waveFile.Flush();
}
}
private void waveSource_RecordingStopped(object sender, StoppedEventArgs e)
{
if (waveSource != null)
{
waveSource.Dispose();
waveSource = null;
}
if (waveFile != null)
{
waveFile.Dispose();
waveFile = null;
}
}
2) After stopping, I insert the array of the recorded stream (MemoryStream.ToArray ()) into the database (SQLite).
3) Getting from the database and converting it to a stream for playback:
Stream stream = new MemoryStream(bytes);
var mp3Reader = new Mp3FileReader(stream);
Mp3FileReader throws an exception: Received frame with sample rate 44100, in MP3 format with sample rate 48000. Mp3FileReader does not support changing the sample rate.
Can anyone tell me where I am doing wrong please. I found some questions but they didn't help me. Sorry If there is a duplicate question. Thanks to
