Java resample.wav sound file without a third-party library

Is it possible to reformat a file .wavfrom 22050 kHz to 44100 kHz in java without using any third-party library?

Perhaps use AudioInputStream?

edit: since it seems that without a third-party library this is not possible, what third-party libraries are there for re-fetching?

Since you are now accepting third-party libraries, here is my suggestion

, -wav . ( ) - Jave , , . , ,

Jave

public void setSamplingRate(java.lang.Integer bitRate)

public class Resample {

public static void main(String[] argv) {
    try {
        File wavFile = new File("C:\\Temp\\test.wav");
        File dstFile = new File("C:\\Temp\\test_half.wav");
        WaveFileReader reader = new WaveFileReader();
        AudioInputStream audioIn = reader.getAudioInputStream(wavFile);
        AudioFormat srcFormat = audioIn.getFormat();

        AudioFormat dstFormat = new AudioFormat(srcFormat.getEncoding(),
