html audio fetch more data on request

I have a problem with html audio element.
Server returns only part of audio file(wav) per request, because it needs some time to generate file and returns only part of it while create in progress, so i need more than one to get full wav file.

It also returns headers like:
Content-Type: audio/wav
Content-Length: length of chunk

My frontend looks like this:

<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Streaming Audio</title>
</head>
<body>
<div>
    <h5>Download file</h5>
    <div class="audio-div">
        <audio controls preload="none">
            <source src="/read" type="audio/wav">
        </audio>
    </div>
</div>
</body>
</html>

Now it’s play only first chunk of audio file, is there any ways to fetch more data to first chunk of audio?
