from django.http import HttpResponse
from django.conf import settings
from pydub import AudioSegment

def create_sound(request):
    original_segment = AudioSegment.from_wav(
        settings.BASE_DIR / "data" / "ding.wav"
    )
    sound = AudioSegment.silent(duration=0)
    for volume_modification in [-20, -10, 0]:
        segment = original_segment + volume_modification
        sound += segment
    sound_data = sound.export()
    return HttpResponse(sound_data, content_type="audio/mp3")

For pydub to function properly, you will also need ffmpeg utility installed in your operating system.
