I have a video file,  I love the background music very much and wish to use it as cellphone ring. But the problem is, I don’t know its name, so can’t download it directly. Now I hope to extract the background music and cut out part of it as cellphone ring. Could someone know which software can make it? By the way, my cellphone supports mp3 format as ring.
many thanks

my video file is .swf, i searched but didn't find any program support converting swf to audio file

thank netu, that program sounds great.
but i have another problem, i just need part of it as ring, could this xilisoft Video Converter support splitting file? I don't want to use 2 or more programs to make it, u know, that's too troublesome

Thanks for your time,netu. I’ll try this video converter
