Beginning in 1755, he studied singing with Johann Walleshauser.
In Rome, Adamberger sang under the italianized stage name Valentino Adamonti from 1775 to 1777. From 1778-1779 he sang at the King's Theatre in London. After returning to Italy briefly for appearances in Florence and Milan, he joined the Singspiel company of the National Court Theater at Vienna. He made his début there on 21 August 1780. The following year, he married the Viennese actress Marie Anne Jacquet (1753–1804); their daughter was Antonie Adamberger, later a popular actress. In 1783, the Singspiel company disbanded but Adamberger was kept on for the Italian company that replaced it. When the Singspiel company was revived in 1785, alongside the Italian, he again became its leading tenor, and when it was disbanded for the second time, in 1789, he returned to the Italian company. In 1793, he retired from the stage but continued as a member of the imperial Hofkapelle and as an eminent singing teacher. He died in Vienna.
