Online voice recorder for singing, help please~?

Okay, so I’ve tried a few recorders, but none are really good, i need a good quality one, or any good tips on how to clean up my voice on Audacity. I have Razer headphones, and i don’t know if they are good, but for this thing i’m doing, i want the quality to sound really great when i do sing, so, any help? Online recorders, downloadable programs, or tips for the program called Audacity?!
