   Could you do something like,

   defmodule AudioStreamer do
     def client do
       Tesla.client([
         {Tesla.Middleware.BaseUrl, "https://audio-service.com"}
       ], {Tesla.Adapter.Finch, name: MyFinch})
     end
     
     def stream_to_wav_file(audio_url, output_path) do
       case Tesla.get(client(), audio_url, opts: [adapter: [response: :stream]]) do
         {:ok, %Tesla.Env{body: stream}} ->
           File.open!(output_path, [:write, :binary])
           |> write_stream_to_file(stream)
           |> File.close()
           
           {:ok, output_path}
         
         {:error, reason} ->
           {:error, reason}
       end
     end
   end
