Yep! Our mix. To be fair, the sound of Neighboring Sounds owes its quality to a handful of professionals, each one contributing its bit to the final result. Without Ricardo's work, I'm sure we wouldn't have such a praised work of sound (the movie is the winner of the Rotterdam FIPRESCI Award 2012 "For evoking an atmosphere of paranoia and menace through a highly ambitious use of sound and cinematography...").
Here is the complete post
sound credits, as in IMDB
(which needs correction, as Pablo Lamar also designed the sound):
Catarina Apolônio .... sound editor
Ricardo Cutz .... sound re-recording mixer
Kleber Mendonça Filho .... sound designer
Carlos Montenegro .... sound mixer
Gera Vieira .... sound mixer
Thanks, Ricardo, for bringing my attention to this.
