Antares say: “The ATR-1 is a rack-mountable hardware implementation of Antares’s Auto-Tune pitch correcting software. Like Auto-Tune, the ATR-1 employs state-of-the-art digital signal processing algorithms (many, interestingly enough, drawn from the geophysical industry) to continuously detect the pitch of a periodic input signal (typically a solo voice or instrument) and instantly and seamlessly change it to a desired pitch (defined by any of a number of user-programmable scales).”

Inputs & outputs are line-level, balanced on XLR connectors & TRS jacks. External power supply is included

Standard rackmount
