Hello,
A brand new version of Circe is available 
! This version is available as VST3 and AudioUnit plugins, as well as an automatic application. It is compatible with MacOS (M series only), Windows and Linux.
Circe lets you modify the pitch and tension of the voice. Used as a plug-in, these parameters can be controlled automatically by analyzing these characteristics from a second audio track defined as a side-chain. Circe can also be used to create a hybrid timbre between the original track and the one defined as a side-chain.
Circe neural auto-encoder model is developed by Frederik Bous and Axel Roebel at IRCAM Analysis-Synthesis Team of the STMS Laboratory.
Circe plug-in and Circe standalone application are designed and developed by Pierre Guillot at IRCAM IMR department.
