To my amusement I haven't found any readily made ringtone of the song Cellular Phone by Dopplereffekt. I just want to make the main theme (about 3.5 sec.) to a cool ringtone but I don't know how to match the beat. So after the theme ends, it should start again by matching the beat.
How do I accomplish this by using free software on Windows? I have Audacity. I can also download free trial version of paid software as well.
Ps. You can find the song on YouTube. I think that's fair use to cut that 3.5 secs out of it. I know how to extract the audio out of YouTube (using FlashGot with Firefox, then extract the audio with FLV Extract), convert it to a WAV (with Fre:ac) and import it to editor software, I just fall short of the beatmatch part.
So far I learned from @Ken that this "beatmatching" is called editing by signature and bars.
