NAudio 사용하기

using System;
using NAudio.Wave;

Guid deviceGUID = Guid.Empty;
DirectSoundOut directSoundOut = new DirectSoundOut(deviceGUID); 
//guid를 이용하여 direct sound out을 생성하면 해당 디바이스 출력을 선택할수 있음

Capabilitues 받아오기

WaveOut.DeviceCount; //디바이스 갯수
WaveOut.GetCapabilities(디바이스인덱스번호).ProductName.ToString(); //디바이스 이름

재생 샘플

using System;
using NAudio.Wave;

static string path_;
Mp3FileReader reader;
WaveOut waveOut = new WaveOut();
private void Start()
{
    path_ =  Application.dataPath + "/StreamingAssets/" + "sample_script_kr_1.mp3";
    reader = new Mp3FileReader(path_);
    //WaveOutCapabilities woc = WaveOut.GetCapabilities(0);
    waveOut.DeviceNumber = 1;
    waveOut.Init(reader);
    waveOut.Play();
}

private void OnApplicationQuit()
{
    waveOut.Stop();
    waveOut.Dispose();
}
  • 전체 파일스트림을 모두 dispose 해주지 않으면 메모리누수로 크래시가 나는것 같음
  • 하단의 샘플코드가 전체 파일스트림을 모두 dispose해서 에러가 없는 상태

크래시 에러 나지 않는 샘플코드
