How can I write a WAV file from byte array in java? [closed]

Answer 1

Writing file from InputStream to OutputStream by reading bytes:

File srcFile = new File("c:/src.wav");
File dstFile = new File("c:/dst.wav");
FileInputStream in = new FileInputStream(srcFile);
FileOutputStream out = new FileOutputStream(dstFile);

byte[] buf = new byte[1024];
int len;
while ((len = in.read(buf)) > 0) {
    out.write(buf, 0, len);
}

in.close();
out.close();
