博主在尝试使用Android模拟器进行音频录制时遇到问题，录音结果出现失真，时长显示为实际两倍。尝试了不同输出格式和编码器，但问题依然存在。已尝试使用MediaRecorder和AudioRecord类，结果相同。问题可能是由于模拟器的限制或是代码实现的错误。

I am trying to record audio from the microphone on the Android emulator with this code:

recorder = new MediaRecorder();

recorder.setAudioSource(MediaRecorder.AudioSource.MIC);

recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);

recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);

recorder.setOutputFile(Environment.getExternalStorageDirectory() + "/test/test.3gp");

try {

recorder.prepare();

}

catch (IOException io) {

Log.v(LOG_TAG, "Could not prepare the audio " + io.getMessage());

}

recorder.start();

For stopping the audio, this is the code:

recorder.stop();

recorder.reset();

recorder.release();

The recording process works fine but the resulting audio that is distorted. When I record an audio for 60 seconds duration and play it, it's duration is being shown as 120 seconds. The measurement is not exact but the this is just to give you an idea.

Only the AMR_NB encoder is working on my emulator. I have tried different output formats but the result is always the same.

Is it a limitation of the emulator or am I doing something wrong here?

Edit 1:

I have tried the AudioRecord class too and the result is the same dragging audio.

Thanks.
