How can I stream audio from base64 chunks?

This question is about javascript on the browser side.

I am receiving chunks with audio in base64 format. Every chunk is up to 750 kB. When I wait and merge chunks in one the audio file plays well.

Can I start to play audio without waiting for all chunks to load?

This code is downloading the whole audio and playing it (works properly):

      let after = ''
      let hasNextPage = true;
      let base64 = ''
      while(hasNextPage){
       let chunk = await downloadChunk(fileId, after)
        base64 += chunk.base64
        after = chunk.after
        hasNextPage = chunk.hasNextPage
       // break
      }
      
      const audio = new Audio()        
      audio.src = base64 
      audio.play()
