Question

musicg API를 사용하여 오디오 매칭 분석을 수행하기 위해 오디오를 동시에 재생하고 녹음하고 있습니다. 나는 원래과 비교하기 위해 파일로 녹음을 저장 한 다음 getScore() 메소드에 전달하기 위해 노력하고있어

: 나는 내 응용 프로그램을 실행 다음과 같은 오류/S 매번 받고 있어요 오디오 파일을 재생하고 일치하는 점수를 반환합니다. 다음은 굵게 표시된 줄을 사용하여 MainActivity의 관련 코드입니다.

       int i = recorder.getState();

Answer 1

나는 문제가 copyWaveFile()의 생각 :

당신은 다음과 같은 코드를 사용하여 (copyWaveFile에 mFileName 변수를 전송)하지만 경로를 변경 :

outFilename = Environment.getExternalStorageDirectory().getPath();

위의 행을 삭제하고 다시 한 번 확인해보십시오. 같은 오류가 계속 발생하면 알려주십시오.
