ooooh, great voice!!!

Even though you are just recording on a phone you can actually get quite a good sound if you import it into a DAW and use some effects.

For example this is my entry for this week's #openmic, which is recorded on an iPhone and then I have used Logic Pro to add some effects -

You could probably do something with a free DAW too. Just have a Google around and watch some YouTube videos and experiment :-)

Look forward to hearing more!
