Witam. Mam problem w postaci zapisywania do pliku, a mianowicie chodzi o to, że program polega na tym, iż wgrywamy piosenkę i możemy z niej "wyciąć" interesujący nas fragment i zapisać do odrębnego pliku. Jednak tutaj pojawia się mój problem. Nie wiem jak zapisać ten wycięty fragment piosenki do pliku? Tutaj jest cały kod:
