我已经使用mediaplayer成功录制了用户的声音,并且该文件存储在SD卡中。 现在我想用音轨播放那个声音。但是当我这样做的时候会产生噪音。 是的。AudioTrack无法正常播放音频文件,因为它会产生噪音
这里是播放声音的代码..
private void PlayAudioFileViaAudioTrack(String filePath) throws IOException
{
// We keep temporarily filePath globally as we have only two sample sounds now..
if (filePath==null)
return;
int intSize = android.media.AudioTrack.getMinBufferSize(44100, AudioFormat.CHANNEL_CONFIGURATION_STEREO,
AudioFormat.ENCODING_PCM_16BIT);
AudioTrack at = new AudioTrack(AudioManager.STREAM_MUSIC, 44100, AudioFormat.CHANNEL_CONFIGURATION_STEREO,
AudioFormat.ENCODING_PCM_16BIT, intSize, AudioTrack.MODE_STREAM);
if (at==null){
Log.d("TCAudio", "audio track is not initialised ");
return;
}
int count = 512 * 1024; // 512 kb
//Reading the file..
byte[] byteData = null;
File file = null;
file = new File(filePath);
byteData = new byte[(int)count];
FileInputStream in = null;
try {
in = new FileInputStream(file);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
int bytesread = 0, ret = 0;
int size = (int) file.length();
at.play();
while (bytesread < size) { ret = in.read(byteData,0, count); if (ret != -1) { // Write the byte array to the track
at.write(byteData,0, ret); bytesread += ret; } else break; } in.close(); at.stop(); at.release(); }

噪音你可以说它是在声音中产生很大的失真,它不是清晰地播放声音。 – AndroidiVore 2014-08-31 11:11:02
