Soulo Karaoke is a sing along app with a library of popular and public domain songs to rock out to. It can be used with the iPhone 3GS and up, and both iPad devices. It’s possible to record using the built in microphone on these devices, but the company (and our testing) deosn’t recommend it. Instead, they also sell the Soulo Mic, a $70 – $100 microphone accessory made to be used with the app.

The microphone plugs into the headphone port and has a little headphone jack to connect headphones or an external speaker. The app also allows video to be output to an external screen, like a TV, but not currently through AirPlay; the wireless version of the Soulo mic has a video adapter that can be used. According to the support website, “audio out through HDMI is not currently supported while in recording mode, but the audio will work through an HDMI connection to play back your finished recordings.”

The microphone hardware is solid, if a bit light in the hand, and is fairly sensitive picking up vocal sounds. The only issue I had with the microphone is the fact that, because it uses the headphone port, the audio out MUST be via headphone or external speaker. No using the iPad or iPhone speakers. In addition, everytime I used the app, it reminded me to use the Soulo mic, as all mics would not work as well as that one. This is when I was using the Soulo Mic.

Using the app is straight forward. Users simply tap the large “Start Singing” button on the Home screen, choose a song (it can be previewed as well), and start singing along. The volume of the backing music and the original vocals can be set, as can the level of Pitch Enhancement, Tone, Reverb and Echo. Soulo records all the performances, allowing users to share the recording via YouTube, Facebook, Twitter, and Email. If a performance isn’t good enough to share, it can be deleted or saved to work on later without sharing. Users can also sing along to any song in their device’s iTunes library, though resulting performances cannot be recorded or shared.

Soulo comes with a fairly robust library of pop, rock, country, hip hop, and dance tunes, with a ton able to be purchased in the in-app Music Store for $0.99 each.

Bottom line, Soulo Karaoke is a great Karaoke app. My daughter and I had a ton of fun singing along to the songs we downloaded, and being able to share the tracks is a nice bonus feature. It would be great if AirPlay was an option for larger parties, but even without it, I’d use this instead of a big fancy Karaoke machine most days.
