Recorder-Android

Recorder 通过 AudioRecord 或 MediaRecorder 录制 MP3 或 AAC 音频文件。

因 Android 默认不支持MP3编码，所以库通过 Lame 编码生成 MP3 音频文件。

系统支持

• Andorid API >= 19

开始使用

录制 AAC 音频 导入 release 文件夹下 recorder-release.aar 即可；

录制 MP3 音频还需导入 mp3lame-release.aar 文件。

使用方式

请求 App 录音机权限

private final String[] permissions = {Manifest.permission.RECORD_AUDIO};

ActivityCompat.requestPermissions(this, permissions, REQUEST_RECORD_AUDIO_PERMISSION);

---

获取保存音频文件的路径。

File dir = getExternalFilesDir("Sounds");
if (dir == null) {
    dir = getFilesDir();
}

mFile = new File(dir, "test.mp3");

---

准备录音机开始捕捉和编码数据。

mRecorder.prepare(mFile);

---

开始录制。

new Thread(mRecorder::start).start();

---

停止录制。

mRecorder.stop();

---

释放与此 Recorder 对象关联的资源。

mRecorder.release();
