how to convert wav to mp3 in live using python?

try python-audiotools. I think it will help you stream the audio file that you want.

I was able to figure out a working approach using flask and ffmpeg...

import selectimport subprocessimport numpyfrom flask import Flaskfrom flask import Responseapp = Flask(__name__)def get_microphone_audio(num_samples):    # TODO: Add the above microphone code.     audio = numpy.random.rand(num_samples).astype(numpy.float32) * 2 - 1    assert audio.max() <= 1.0    assert audio.min() >= -1.0    assert audio.dtype == numpy.float32    return audiodef response():    pipe = subprocess.Popen(        'ffmpeg -f f32le -acodec pcm_f32le -ar 24000 -ac 1 -i pipe: -f mp3 pipe:'        .split(),        stdin=subprocess.PIPE,        stdout=subprocess.PIPE,        stderr=subprocess.PIPE)    poll = select.poll()    poll.register(pipe.stdout, select.POLLIN)    while True:        pipe.stdin.write(get_synthetic_audio(24000).tobytes())        while poll.poll(0):            yield pipe.stdout.readline()@app.route('/stream.mp3', methods=['GET'])def stream():    return Response(        response(),        headers={            # NOTE: Ensure stream is not cached.            'Cache-Control': 'no-cache, no-store, must-revalidate',            'Pragma': 'no-cache',            'Expires': '0',        },        mimetype='audio/mpeg')if __name__ == "__main__":    app.run(host='0.0.0.0', port=8000, debug=True)

This solution allows for live streaming and is supported in Chrome, Firefox, and Safari.
