Rocking the mic
Soulo sent along the $69.99 wired mic kit for me to embarrass myself with. A $99.99 Bluetooth mic kit is also available.
The mic itself has a pleasant heft to it and the cord gives you an opportunity to swing it around like Roger Daltrey (though this probably voids the warranty and could leave your iPad in ruins).
Soulo has helpfully included a small external speaker to make up for the fact that plugging the mic into your audio jack cancels out the built-in speakers.
You may have to monkey with the iPad's volume switch before singing a song. A patch is on the way to smooth out the volume control.
Soulo songs cost 99 cents, though you get a few free bonus tracks with your mic. The Soulo songs have the advantage of coming with lyrics and cues ready. I tried out several before settling on making a video of "House of the Rising Sun." (See below.)
To my dismay, "Never Gonna Give You Up" is not among Soulo's offerings. There goes my dream of personally Rickrolling everyone I know.
The app does a reasonably good job of lowering the real vocal tracks on your iTunes songs so you can sing along without competing directly with Whitney Houston. You can manually enter the lyrics to your own library through iTunes and Soulo will display them.
Share your masterpiece
The app's audio and video recording and sharing capabilities only come into play with songs purchased from Soulo. This is disappointing, but not surprising considering how copyright kerfuffles can flare up.
You are also limited to sharing one-minute clips, so your friends won't know if you knocked that final note out of the park.
The reverb, echo, and pitch correction controls can make your singing sound a lot better than it actually is. This is great for those karaoke dreamers who can't hold a tune.
Soulo may have some limitations with sharing and official song selection, but the ability to dip into your iTunes portfolio means you'll never run out of material for your home karaoke parties.
