[C#/COMMON/NAUDIO/.NET5] WaveFormat 클래스 : CreateALawFormat 정적 메소드를 사용해 G.711 a-law 같은 포맷 사용하기

■ WaveFormat 클래스의 CreateALawFormat 정적 메소드를 사용해 G.711 a-law 같은 포맷을 사용하는 방법을 보여준다.

▶ 예제 코드 (C#)


using System.IO;

using NAudio.Wave;

string sourceAudioFilePath = @"D:\source.bin";
string targetAudioFilePath = @"D:\target.wav";

WaveFormat sourceWaveFormet = WaveFormat.CreateALawFormat(8000,1);

using(FileStream sourceFileStream = File.OpenRead(sourceAudioFilePath))
{
    using(RawSourceWaveStream reader = new RawSourceWaveStream(sourceFileStream, sourceWaveFormet))
    {
        using(WaveStream provider = WaveFormatConversionStream.CreatePcmStream(reader))
        {
            WaveFileWriter.CreateWaveFile(targetAudioFilePath, provider);
        }
    }
}

using System.IO;

using NAudio.Wave;

string sourceAudioFilePath = @"D:\source.bin";

string targetAudioFilePath = @"D:\target.wav";

WaveFormat sourceWaveFormet = WaveFormat.CreateALawFormat(8000,1);

using(FileStream sourceFileStream = File.OpenRead(sourceAudioFilePath))

{

using(RawSourceWaveStream reader = new RawSourceWaveStream(sourceFileStream, sourceWaveFormet))

{

using(WaveStream provider = WaveFormatConversionStream.CreatePcmStream(reader))

{

WaveFileWriter.CreateWaveFile(targetAudioFilePath, provider);
