When people say "auto-tune" (lowercase), they are usually referring to Antares. Released in 1997, Auto-Tune is the industry standard. It is the sound of the iconic "Cher effect" and the T-Pain style hard tuning used in modern Hip-Hop and Trap.
Auto-Tune operates on two main modes: Automatic and Graphical.
Waves Tune Real-Time is often described as "smoother" and "creamier" than Auto-Tune. While it can certainly achieve the hard-tuning effect, its default algorithms tend to glide into pitch correction rather than snapping abruptly. It excels at transparent correction where the listener shouldn't know processing is happening. waves real time tune vs autotune
Waves RTT handles fast retune speeds differently. Instead of sliding, it often creates a stepped, "formant jogging" effect. Because it doesn't look ahead, when you hit a note 20 cents sharp, RTT immediately snaps it to the grid. This creates a slight "glottal chop"—a tiny click in the vocal fry.
Subjectively:
Antares Auto-Tune Pro, when used in Low Latency Mode, sits around 1.8ms to 2.5ms depending on your sample rate. This is excellent. However, for live sound engineers (using Auto-Tune Live), the stability is good, but the CPU hit is slightly higher than Waves.
True to its name, Waves Tune Real-Time is built for speed. It is incredibly lightweight on CPU and features a clean interface focused almost entirely on the "Automatic" style of correction. It lacks the deep, manual note-by-note editing of Antares’s Graphical Mode or the full MIDI editing capabilities of the standard Waves Tune plugin.

Many top engineers use both. Here is the workflow:
This gives you the best of both worlds: Instant response during recording + surgical precision during mixing. Antares Auto-Tune Pro, when used in Low Latency
When comparing Waves Tune Real-Time (WTRT) and Antares Auto-Tune, the choice usually boils down to price vs. prestige. Waves is the "budget beast" that offers deep control for a fraction of the cost, while Antares is the industry standard with a smoother, more "expensive" sonic character.
