發(fā)布時間：2023/12/16 编程问答 25 豆豆

生活随笔收集整理的這篇文章主要介紹了 java wav 转 mp3_java,wavToMP3格式转换小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.

若有朋友需要WAV 音頻裁剪，可以參考我的另外一篇博文——wav 音頻裁剪http://blog.csdn.net/daltsoftware/article/details/71480664
在android開發(fā)中，一說到音視頻，程序員第一反應肯定是FFMpeg，但是FFMpeg這個庫，又復雜，又性能差，如果只想簡單的要個音頻裁剪的功能，就要去引入這么大的庫，完全不值得。然而自從android api 16之后谷歌就開始在音視頻方面進行布局，android 18之后繼續(xù)豐富音視頻編碼庫，讓很多android app在不依賴于繁瑣jni就能進行一些基礎的音視頻開發(fā)。下面將是基于android api16的對mp3文件進行裁剪的代碼例子。當前由于時間問題，先分享最主流的mp3格式的音頻裁剪，以后有時間會分享更多其他音頻方面的經驗。

//適當?shù)恼{整SAMPLE_SIZE可以更加精確的裁剪音樂private static final int SAMPLE_SIZE = 1024 * 200;

BufferedOutputStream outputStream = null;
try {

extractor.setDataSource(inputPath);
int track = getAudioTrack(extractor);
if(track < 0){
return false;
}
//選擇音頻軌道
extractor.selectTrack(track);
outputStream = new BufferedOutputStream(
new FileOutputStream(outputPath), SAMPLE_SIZE);

//跳至開始裁剪位置
extractor.seekTo(start, MediaExtractor.SEEK_TO_PREVIOUS_SYNC);
while (true){
ByteBuffer buffer = ByteBuffer.allocate(SAMPLE_SIZE);
int sampleSize = extractor.readSampleData(buffer, 0);
long timeStamp = extractor.getSampleTime();
// >= 1000000是要裁剪停止和指定的裁剪結尾不小于1秒，否則可能產生需要9秒音頻
//裁剪到只有8.6秒，大多數(shù)音樂播放器是向下取整，這樣對于播放器變成了8秒，
// 所以要裁剪比9秒多一秒的邊界
if(timeStamp > end && timeStamp - end >= 1000000){
break;
}
if(sampleSize <= 0){
break;
}
byte[] buf = new byte[sampleSize];
buffer.get(buf, 0, sampleSize);
//寫入文件
outputStream.write(buf);
//音軌數(shù)據(jù)往前讀
extractor.advance();
}

} catch (IOException e) {e.printStackTrace();}finally {if(extractor != null){extractor.release();}if(outputStream != null){try {outputStream.close();} catch (IOException e) {e.printStackTrace();}}}return true;

}

裁剪音樂的步驟在注釋中已經寫得很明白了，其實用上面簡單的代碼就能實現(xiàn)音頻裁剪了，而且裁剪的音頻經過多項硬指標測試是沒有問題的。但可能還是有人會懷疑用上述方法是否得到一個“真正”mp3文件。絕大部分情況下，產品經理的需求都是希望裁剪后的音樂除了長度之外，其他的都和原始音頻一樣，以防不同的播放器由于編解碼庫的差異，導致播放失敗的情況。下面的代碼是用來提取音頻的關鍵數(shù)據(jù)，來比較裁剪之后的音頻和原始音頻的關鍵數(shù)據(jù)是否一樣。

@TargetApi(Build.VERSION_CODES.JELLY_BEAN) private static void printMusicFormat(String musicPath){try {MediaExtractor extractor = new MediaExtractor();extractor.setDataSource(musicPath);MediaFormat format = extractor.getTrackFormat(getAudioTrack(extractor));Log.i("music", "碼率：" + format.getInteger(MediaFormat.KEY_BIT_RATE));Log.i("music", "軌道數(shù):" + format.getInteger(MediaFormat.KEY_CHANNEL_COUNT));Log.i("music", "采樣率：" + format.getInteger(MediaFormat.KEY_SAMPLE_RATE));} catch (IOException e) {e.printStackTrace();} }

通過反復驗證，通過以上方法裁剪的音頻除了時間長度之外，其他格式數(shù)據(jù)都和原始音頻一樣，裁剪的音頻在各種平臺（android， IOS, windows,mac）都能正常的播放和使用。
