Note: Audacity does not have a built-in "Auto-Tune" plugin like Antares Auto-Tune. Instead, this review covers the native tools ( Pitch Correction and Sliding Stretch ) and how they compare to professional pitch correction software.

If you set the "Retune Speed" to a very slow setting (e.g., 0.2 seconds) and the "Threshold" low, you can smooth out a shaky vibrato without turning the vocalist into a robot. I recorded a demo of "Hallelujah" where the chorus was drifting sharp. A light pass of the default correction made it listenable—not perfect, but listenable. auto tune audacity
You select "C Major" and hit OK. Audacity moves every note to the nearest C Major note. Sounds great in theory. In practice, a blue note (like a bluesy flat third) or a passing tone gets snapped to a diatonic pitch, destroying the emotional intent of the performance. There is no option to "keep chromatic notes" or adjust sensitivity per note. Note: Audacity does not have a built-in "Auto-Tune"
Audacity deserves credit for including pitch correction in open-source software. It works mathematically. But in the world of audio production, "mathematically correct" is rarely "musically correct." The artifacts, the lack of real-time feedback, and the destructive editing workflow make it a frustrating tool for anything beyond a one-off fix. I recorded a demo of "Hallelujah" where the
For bass guitar or synth leads, the Sliding Stretch is excellent. It allows you to draw a curve to slowly glide a note up or down over time. This is great for fixing the tail end of a sustained note that went flat. The Bad (And Often, The Ugly) 1. No real-time playback. This is the biggest hurdle. In Reaper (with ReaTune) or FL Studio (with NewTone), you sing, you see the pitch graph, you drag the line. In Audacity, you guess, select, apply, listen, undo, and repeat. For a three-minute vocal track, this turns a 10-minute job into a two-hour nightmare.
After spending three years using Audacity for vocal production (mostly as a hobbyist and occasionally for demo recordings), I have developed a love-hate relationship with its pitch correction capabilities. Here is the long, unflinching review. Audacity comes with two native tools for pitch manipulation: Effect > Pitch and Tempo > Pitch Correction (which uses the MASTER algorithm) and the more surgical Effect > Pitch and Tempo > Sliding Stretch . There is no real-time monitoring, no graphical "blobs" on a piano roll, and definitely no "Chesney" or "T-Pain" presets.
