h5 mediarecorder 音频录制 ios无法播放

好的，以下是一个简单的录制 WAV 音频文件的示例代码： ```java import android.media.AudioFormat; import android.media.AudioRecord; import android.media.MediaRecorder; import android.os.Environment; import android.util.Log; import java.io.File; import java.io.FileOutputStream; import java.io.IOException; public class AudioRecorder { private static final String TAG = "AudioRecorder"; private static final int SAMPLE_RATE_IN_HZ = 44100; private static final int CHANNEL_CONFIG = AudioFormat.CHANNEL_IN_MONO; private static final int AUDIO_FORMAT = AudioFormat.ENCODING_PCM_16BIT; private AudioRecord audioRecord; private boolean isRecording; public void startRecording() { int minBufferSize = AudioRecord.getMinBufferSize(SAMPLE_RATE_IN_HZ, CHANNEL_CONFIG, AUDIO_FORMAT); audioRecord = new AudioRecord(MediaRecorder.AudioSource.MIC, SAMPLE_RATE_IN_HZ, CHANNEL_CONFIG, AUDIO_FORMAT, minBufferSize); isRecording = true; audioRecord.startRecording(); new Thread(new Runnable() { @Override public void run() { writeDataToFile(); }).start(); public void stopRecording() { isRecording = false; audioRecord.stop(); audioRecord.release(); private void writeDataToFile() { byte[] buffer = new byte[1024]; String filename = Environment.getExternalStorageDirectory().getAbsolutePath() + "/recording.wav"; File file = new File(filename); if (file.exists()) { file.delete(); try { FileOutputStream fos = new FileOutputStream(file); while (isRecording) { int read = audioRecord.read(buffer, 0, buffer.length); fos.write(buffer, 0, read); fos.close(); } catch (IOException e) { Log.e(TAG, "writeDataToFile: ", e); ```

要在Android Mediarecorder中录制声音，需要设置音频源，并且确保录制权限已被授予。可以使用以下代码来设置音频源： mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC); ```
