need to load audio file in any format, in byte[] array which has specific audio format such as two channels and special sample rate etc.

any help will be appreciated.

What I have tried:

got this code to load a .wav file into bye[] by it just works with .wav plus I have no idea what kind of audio format that byte array has:

ByteArrayOutputStream out = new ByteArrayOutputStream();
		            BufferedInputStream in = null;
					try {in = new BufferedInputStream(new FileInputStream(A_WAVE_FILE));} 
					catch (FileNotFoundException e1) {e1.printStackTrace();}
		            int read;
		            byte[] buff = new byte[1024];
		            try {while ((read = > 0){out.write(buff, 0, read);}} 
		            catch (IOException e1) {e1.printStackTrace();}
		            try {out.flush();} catch (IOException e1) {e1.printStackTrace();}
		            byte[] audioBytes = out.toByteArray();

That's a lot of code just to do this:
byte[] buffer = File.readAllBytes(filepath);

Yeah, I get it. The entire file is going to be pulled into memory and could run the machine out of RAM. But for a test project just to learn how to parse the data, it'll do just fine.

The trick is interpreting the bytes once you have them. You need to write code for each file type you want to support. The data you get in the buffer is NOT going to be interpreted for you.

The OP is using Java; wouldn't they need Files.readAllBytes instead of the .NET File.ReadAllBytes? :)

Whoops. :shucks: Can you guess what I use all day?
You need to examine the content of the file to know which format it is. Google will find you documentation and samples on audio formats.
