Hello, I am from China, my English is not very good, I think I need your help, and I need some help,
I want to change the format of audio files
The original audio file format
Bit rate 256Kbps
The audio sample size 16
Audio sampling level 16KHZ
Audio formats PCM
Convert to
Bit rate 64Kbps
The audio sample size 8
Audio sampling level 8KHZ
Audio formats CCITT A-Law
However, I met some problems, abnormal system prompts the Naudio.MmException AcmNotPossible calling acmStreamOpen
I test code is such
NAudio.Wave.WaveFormat format = NAudio.Wave.WaveFormat.CreateALawFormat ( 8000, 1);
Try
{
NAudio.Wave.WaveFileReader fileread = new WaveFileReader ( @" E: \ 1.wav" );
NAudio.Wave.WaveStream WaveStream = new WaveFormatConversionStream ( format, fileread );
NAudio.Wave.WaveFileWriter.CreateWaveFile ( @" E: \ 2.wav", WaveStream );
Console.WriteLine (" OK" );
}
Catch ( ExecutionEngineException Ex )
{
Console.WriteLine ( ex.ToString ( ) );
}
Console.ReadKey ( );
Excuse me, what is wrong.
