I just did Budi Rahardjo's tips to convert my cassette collections to mp3 using Audacity. Last week I have bought a "line-in line-out" connection at Saturn for 5,- Euro and installed Audacity in my Notebook.
My first cassette converted to mp3 is KLa Project Album No.5 with 8 songs with their hits "Romansa". If I am not wrong, this song was quite popular on 1995. My next cassette to be converted maybe Qur'an recitation.
