Out ot memory

Question

I got this error: Java lang out of memory when i am saving audio in aByteArrayOutputStream,i can only record about 8 minutes. The initial size of memory is: 256m
My code is:
public void run(){
       int frameSizeInBytes = frtoData.getFrameSize();
       int bufferLengthInFrames = line.getBufferSize() / 8;
       bufferLengthInBytes = bufferLengthInFrames * frameSizeInBytes;
       bufferTemp = new byte[bufferLengthInBytes];
       while (!stopped) {
                if (paused) {
                    synchronized (this) {
                        while (paused) {
                            try {
                                position = (int) (line.getMicrosecondPosition() / 1000000);
                                this.wait();
                            } catch (InterruptedException ex) {
                                Logger.getLogger(Audio.class.getName()).log(Level.SEVERE, null, ex);
                if ((numBytesRead = linea.read(bufferTem, 0, bufferLengthInBytes)) == -1) {
                    break;
                 rewind.write(bufferTemp 0, numBytesRead);
code}
rewind is an object of a class: RewindAudio that extends from ByteArrayOutputStream.
I can save more data audio,about 17 minutes, if i increment the size of memory with this: -Xmx450m, but i have to get to at least 1 hour.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       

Answer 1

About the analysis of volumen can you tell what is the logic that you use, because i have a method that needs and array of bytes to make the analysis:
public void setVolume(byte[] b, int off, int length) {
        int finalBuffer = off + b.length;
        int sampleRate = (frtoDatos.getSampleSizeInBits() + 7) / 8;
        int max = 0;
        if (sampleRate == 1) {
            //8 bits:
            for (; off < finalBuffer; off++) {
                int muest = (byte) (b[finalBuffer] + 128);
                if (muest< 0) {
                    muest = -muest;
                if (muestreo > max) {
                    max = muest;
            maxVolume = max;
        } else if (sampleRate == 2) {
            if (frtoDatos.isBigEndian()) {
                // 16-bit big endian
                for (; off < finalBuffer; off += 2) {
                    int muest = (short) ((b[off] << 8) | (b[off + 1] & 0xFF));
                    if (muest< 0) {
                        muest = -muest;
                    if (muest > max) {
                        max = muest;
            } else {
                // 16-bit little endian
                for (; off < finalBuffer; off += 2) {
                    int muest = (short) ((b[off + 1] << 8) | (b[off] & 0xFF));
                    if (muest < 0) {
                        muest = -muest;
                    if (muest > max) {
                        max = muest;
            maxVolume= max >> 8;
        } else {
            maxVolume = -1;
        prgVolumen.setValue(maxVolume);  // setting the maxVolume in a JProgressBar
    }I need the arrary because I m reading from the line, an saved what i 've got in an array of bytes.
I will continue posting tomorrow, because know i got go to my classes.
