Hailed as a \"holy grail of recording,\" by Recording magazine (and adopted worldwide as the largest-selling audio plug-in of all time), Auto-Tune corrects intonation problems in vocals or solo instruments, in real time, without distortion or artifacts. Auto-Tune also preserves all of the expressive nuance of the original performance - with audio quality so pristine that the only difference between what goes in and what comes out is the intonation. All with a user-interface that is a model of clarity, speed and ease-of-use. For most common pitch problems, Auto-Tune Evo\'s Automatic Mode instantaneously detects the pitch of the input, identifies the closest pitch in a user-specified scale (including minor, major, chromatic and 26 historical and microtonal scales), and corrects the input pitch to match the scale pitch. A Retune Speed control lets you match the retune rate to virtually any performance style. For meticulous tweaking, the Graphical Mode displays the performance\'s detected pitch envelope and allows you to specify the desired pitch using a variety of graphics tools. This mode gives complete control over the correction or modification of the most elaborate expressive gestures. Auto-Tune is used daily by thousands of audio professionals around the world. Whether to save studio and editing time, ease the frustration of endless retakes, to save that otherwise once-in-a-lifetime performance, or to create striking special effects, Auto-Tune Evo is the tool of choice.Here are some key features of \"Auto-Tune Evo\":
