Vanessa Campbell has Singaling (iTunes Link) for the iPhone, iPod Touch, and iPad in the iTunes App Store for FREE (regularly $6.99) for a limited time.

Singaling turns your iPad and iPhone into a vocal effects processor.

To get started, simply connect a pair of headphones and sing into your device. (Vocalists can also connect an XLR, studio, or other professional microphone).

Singaling’s clean and fun interface will have you manipulating your vocals in no time, helping you re-create the sounds of your favorite artists, or inventing your own custom vocal effects settings for a whole new world of musical possibilities. Save your favorite settings as presets. Record yourself singing, rapping or talking with Singaling’s studio-quality effects. Share your recordings via text, email, or iTunes (iOS 7).

If you’re looking for a professional vocal pedal to use for recording and/or for live performance, Singaling allows you to connect an XLR, studio or other professional microphone. Plug in your Apple Earpods, iRig mic, Apogee Jam, or other audio connector and sing live using Singaling as your vocal effects pedal.

Singaling is compatible with Audiobus, so its easy to use with other Audiobus-compatible music apps.

For the professional and novice vocalist alike, Singaling combines a state-of-the-art multi effects processor with an incredibly simple user interface to make playing around with vocal effects as easy as possible. Onstage, in the studio, or with friends, Singaling is the fun way to add quality to your voice.
