특정 오디오를 재생할 Android 앱을 개발 중입니다. 이 오디오는 코드에 의해 생성됩니다. 내 문제는 최대 100KHz까지 샘플 속도가 필요하지만 아래 오류 메시지가 나타납니다. 누구든지 AudioTrack으로 100KHz로 샘플 속도를 설정하는 방법을 알고있을 수 있습니다. 감사.Android에서 AudioTrack을 사용하여 샘플 속도를 100KHz로 설정하는 방법은 무엇입니까?
PS : 나는 AudioTrack
--------------- 코드의 시작을 사용하는 이유 내가 아는 한는 만 AudioTrack 오디오 데이터를 수정할 수, 즉 -----입니다 --------------
audioTrack = new AudioTrack(AudioManager.STREAM_MUSIC,
100000,
AudioFormat.ENCODING_PCM_16BIT,
(int)minSize,
AudioTrack.MODE_STREAM);
