"5 sec is not enough"
Good options (different formats, mono\stereo, bit) and good converting
5 sec is not enough for my decision to buy it.
cann't resize a window
If you need it for iPhone ringtone making, I'll recommend you a free online converters.
If you need it for audio converting, this program has a right to exist.
