The Pitch ‘N Time LE 3.0 Software from Serato is a professional time-stretching and pitch-shifting plug-in that can change the length of a piece of audio with natural sounding results. It can be used as a creative tool in applications such as sound design, films, recording, mixing, and more. It can also change the key of the audio up or down in pitch (or transposed) without compromising quality, definition or intelligibility. The software can modify the tempo from 1/2 to 2x speed of the original.
