android录音buffer数据实时存储到txt

求助，我使用audiorecord录制声音，放到buffe中，怎么把缓存里面的数据全部保存到txt文档或excel文件中啊。有源码最好了。另数字低通滤波器JAVA的实现，要对数据进行处理如何操作。

                public RecordThread(AudioRecord audioRecord, int recBufSize) {

                        this.audioRecord = audioRecord;

                        this.recBufSize = recBufSize;

                }

                public void run() {

                        try {

                                short[] buffer = new short[recBufSize];

                                audioRecord.startRecording();// 开始录制

                                while (isRecording) {

                                        // 从MIC保存数据到缓冲区

                                        int bufferReadResult = audioRecord.read(buffer, 0,

                                                        recBufSize);

                                        short[] tmpBuf = new short[bufferReadResult / (rateX)];

                                        for (int i = 0, ii = 0; i < tmpBuf.length; i++, ii = i

                                                        * rateX) {

                                                tmpBuf[i] = buffer[ii];

                                        }

                                        synchronized (inBuf) {//

                                                inBuf.add(tmpBuf);// 添加数据

                                        }

                                }

                                audioRecord.stop();

                        } catch (Throwable t) {

                        }

                }

        }

     录音 buffer 存储滤波 android --------------------编程问答-------------------- 不是用OutputFileStream寫到文件中嗎？ --------------------编程问答-------------------- 和下载一样啊   读到一定的缓存就写到文件里面去
byte[] buf = new byte[1024 * 10];
int read = 0;
while ((read = inputStream.read(buf)) != -1) {
       file.write(buf, 0, read);} --------------------编程问答--------------------

和下载一样啊读到一定的缓存就写到文件里面去
byte[] buf = new byte[1024 * 10];
int read = 0;
while ((read = inputStream.read(buf)) != -1) {
file.write(buf, 0, read);}

存储到txt里面呢
FileOutputStream outStream = new FileOutputStream("/sdcard/"+name+".txt",true);
有这方面的例子或者讲解吗？ --------------------编程问答-------------------- 你有缓存变量，直接贴代码。
BufferedOutputStream out=new BufferedOutputStream(new FileOutputStream("XXX.txt"));
byte[] b= new byte[1024];
out.write(b, 0, b.length);
当然，我这是简单的写法，你还要判断一下，因为我这里是小于等于1024个字节，如果多余，你就要使用while循环
--------------------编程问答--------------------

public void saveToSDCard(String name, String content) throws Exception{

         //获取外存储设备路径Environment.getExternalStorageDirectory()

		 File file = new File(Environment.getExternalStorageDirectory(),name+".txt");

		 FileOutputStream outStream = new FileOutputStream(file);

         outStream.write(content.getBytes());

	     outStream.close();

	

	}

看了这样一段代码，没有理解整个存储的流程 --------------------编程问答-------------------- count = System.in.read(buffer);
read（byte）不能读short[] buffer --------------------编程问答-------------------- 先存储到一个临时文件然后 stream 到一个 txt文件
