Note: Sing only supports wired headset because the bluetooth headset generates latency and therefore the voice may not be synchronized with the backing track. You do not have the songs to sing? Go to the support site of the app and read how to do ... Are you a singer? Sing! Are you not a singer? Sing! Sing is the revolutionary app that helps you in taking control of your music and exploring your vocal skills! You can use it live, thanks to its zero latency, or to practice over your songs, recording and listening to your performances! Import your songs from the Library, Email, and other apps present in the device and sing along with them, while you get a full control over your voice and your tracks! Add effects to your voice to sing like a pro using the effect pedals provided in Sing! All the effects are top class, and come with advanced customizations for professional use. Reverb pedal comes for free with the app, and you can buy all the other pedals to complete your kit: add compressor, delay and equalizer filters to Sing and find out why this app is the best in its genre! You only need a pair of headphones: Sing records your voice without latency and mixes it with track, you can use the internal microphone (you will be impressed by the quality of the recordings!) or your own external mic, attached using one of the many peripherals available for iOS (for example Tascam iXZ, iRig Pro, iRig Mic and iRig PRE). Once you are happy with the results, why don't you listen to the outcome and share it via email or using one of your apps for sharing contents (like Dropbox or SoundCloud)? With Sing a couple of taps is all it takes! Sing and unleash the star in you! Note: tested with Tascam iXZ, iRig Pro and iRig Mic. Only tracks without DRM can be imported. *** If you have problems just fill the form on the support website, you will be contacted ASAP.
