--- 1. FFmpeg yo'lini TIZIMGA tanitish (Importlardan oldin!) ---

Winget orqali o'rnatilgan yo'lni tekshiramiz

ffmpeg_links = os.path.expandvars(r"%LOCALAPPDATA%\Microsoft\WinGet\Links")

Agar bu yo'l mavjud bo'lsa, uni Windows-ning vaqtinchalik PATH ro'yxatiga qo'shamiz

if os.path.exists(ffmpeg_links):
os.environ["PATH"] += os.pathsep + ffmpeg_links

ENDI pydub-ni import qilamiz. Endi u xatolik bermaydi, chunki tizimdan topadi.

from pydub import AudioSegment, effects
