What tools would you recommend for someone who has no vocal range and sounds like a death rattle? I just want to record demos. I've looked at some vocal software but the learning curve is probably longer than my life expectancy.
If by "vocal software" you mean synthetic voices like the Vocaloids, I use
Emvoice instead of trying to sing myself. It's really very, very, very easy to use and would be great for demos, if you don't really need to nail a perfect articulation.
If you really don't want a robot demo, but you really don't want to sing, you can always make a
secret robot demo and send it to an online service singer to make a human demo.
