【问题描述】:
我正在开发一个使用 AudioRecorder 类录制声音的 Android 应用程序 以下来自我的代码:
public void start() throws IOException {
String state = android.os.Environment.getExternalStorageState();
if(!state.equals(android.os.Environment.MEDIA_MOUNTED)) {
throw new IOException("SD Card is not mounted. It is " + state + ".");
}
// make sure the directory we plan to store the recording in exists
File directory = new File(path).getParentFile();
if (!directory.exists() && !directory.mkdirs()) {
throw new IOException("Path to file could not be created.");
}
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
System.out.println("mashi");
recorder.setOutputFormat(MediaRecorder.OutputFormat.DEFAULT);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setAudioEncodingBitRate(16);
recorder.setAudioSamplingRate(44100);
try {
recorder.setOutputFile(path);
System.out.println("ooutput");
} catch (IllegalStateException e) {
e.printStackTrace();
}
recorder.prepare();
recorder.start();
}
录制的声音很慢很厚!! 有什么问题?
