mmsplayer v2 java 之(mmsTrack 音频类)

package com.weiny.mms; import android.media.AudioFormat; import android.media.AudioManager; import android.media.AudioTrack; import android.util.Log; public class mmsTrack { int mFrequency; // 采样率 int mChannel; // 声道 int mSampBit; // 采样精度 AudioTrack mAudioTrack; public mmsTrack(int frequency, int channel, int sampbit){ mFrequency = frequency; //mChannel = channel; //mSampBit = sampbit; if(channel==1) mChannel=AudioFormat.CHANNEL_CONFIGURATION_MONO; else if(channel==2) mChannel=AudioFormat.CHANNEL_CONFIGURATION_STEREO; if(sampbit==8) mSampBit=AudioFormat.ENCODING_PCM_8BIT; else if(sampbit==16) mSampBit=AudioFormat.ENCODING_PCM_16BIT; } public void init(){ if (mAudioTrack != null){ release(); } int minBufSize = AudioTrack.getMinBufferSize(mFrequency, mChannel, mSampBit); mAudioTrack = new AudioTrack(AudioManager.STREAM_MUSIC, mFrequency, mChannel, mSampBit, minBufSize, AudioTrack.MODE_STREAM); mAudioTrack.play(); } public void release(){ if (mAudioTrack != null){ mAudioTrack.stop(); mAudioTrack.release(); mAudioTrack=null; } } public int playAudioTrack(byte []data, int offset, int length){ int nResult=0; if (data == null || data.length == 0){ nResult=1; return nResult; } try { mAudioTrack.write(data, offset, length); } catch (Exception e) { // TODO: handle exception e.printStackTrace(); nResult=1; } return nResult; } public int getPrimePlaySize(){ int minBufSize = AudioTrack.getMinBufferSize(mFrequency, mChannel, mSampBit); return minBufSize * 2; } }

这个音频类是通用的，大家可以用于其他的方面。之前说过，V2.0的JAVA部分代码会开放，现在我做到了。免得代码费劲去破解我的代码。哈哈。
