How to write audio stream to file in python3

I am working with Nexmo. I would like to save live stream Nexmo call audio to my disk. I have implemented web socket to read Nexmo's stream. Please find below the code where I append audio to an existing audio file. 

#!/usr/bin/env python

# WS server example

import asyncio
import websockets

async def nexmoServer(websocket, path):
    audioData = await websocket.recv()

    input_filename = "sample_harshit.wav"
    output_filename = "new_file.wav"
    ifile = open(input_filename,'rb')
    ofile = open(output_filename, 'wb')
    data = audioData
    while data:
        ofile.write(data)
        data = ifile.read(1024*1024)
    ofile.close()
    ifile.close()

The audio file's length is updated but audio data is not written in the file.

Atleast this is working fine:

def nexmoServer():
    input_filename = "a.wav"
    output_filename = "b.wav"
    ifile = open(input_filename,'rb')
    ofile = open(output_filename, 'wb')
    data = ifile.read(1024*1024)
    while data:
        ofile.write(data)
        data = ifile.read(1024*1024)
    ofile.close()
    ifile.close()

nexmoServer()
