1) You can in the traditional way. In the form, use the input tag with the file type with the restriction set to accept only *.mp3. The form is submitted by a button with type submit.
2) In an advanced way. The form also uses the input tag with the file type, which is restricted to only accept *.mp3. The difference is that you need to send the form fields without fail only through an ajax request. In this case, the field with the file is read using the FileReader object (old browsers do not have it, for example, IE 10-, so the method does not roll for them), a binary request packet is formed in a special way, and this packet in the form of base64 is transmitted by Ajax to the server.
PS: no matter what method of sending you choose, the file can be attached to the form only at the initiative of the user, regardless of whether you use a simple form submission or try to pick up the file from the input FileReader.
