About 15+ years ago I work in the recording and divulgation of sounds recorded in nature. I studied together with the curator of the neotropical sound archive, Jacques Vielliard, at the State University of Campinas (UNICAMP) in Brazil.

I am currently a contributor to the sound collection Macaulay Library, the most important nature sounds library in the world.

In February 2014 I was the winner of the first edition of the SuperBrains program - broadcast by the National Geographic channel - for my ability to identify birds by their songs.

I have published more than 12 works portraying the sounds of birds in the Americas. I have also lectured and taught courses in various conferences focused on nature in general and birds in particular.

An event that marked my career was to be invited to Cornell University, in New York (United States), where I offered a conference entitled "A World of Sounds" in which sound landscapes of the places where I recorded were protagonists with its emblematic sounds

The recording technique that I chose for these sounds gives a very special detail.

 For you to enjoy them I recommend you use headphones. It's like listening in HD.

I recorded this unique selection of sounds in Argentina, Brazil, Colombia and Paraguay.

A soundscape lets you know a place in a relaxing way. The sound sensations cause peace and tranquility. Over the course of several years I have recorded many dawns, sunsets, nights... sounds that will make your stress level go down.

Bird Audioguides

A bird audio guide portrays the sounds of birds in a country, a region or just the birds that occur in a forest. In my career I have recorded many species of birds mainly in Brazil, Paraguay and Colombia.

Sound Editing

Prepare dialogues for the most diverse uses; Restore old recordings; Mix sounds for a telephone station...


These are some examples of what I am prepared to do, always with the highest levels of technology so that the result of the work is first world.
