Synthetic

Acoustic Niche

----------------

Ongoing project (2023 - ) related to the synthesis of artificial biophonic-like sound sources (a database created using synthesizers during recording sessions at WORM Sound Studios as well as digital recipes using SuperCollider SynthDefs) with the aim to create a synthetic acoustic niche generation tool for multichannel sound installations and performances.

Acoustic

Monitoring Tool

----------------

Ongoing project (2023 - ) of a low level optimized software tool designed to run on low cost DIY acoustic monitoring devices for long time recording data in remote locations. Inial tests were carried out with a prototype using: Raspberry Pi Zero/Zero W; INMP441 MEMS I2S microphone module; USB Powerbank (> 10000mAh); and a VHS case. Source code and further information

Axioma

----------------

Modular synthesizer audio plugin modules developed for the open-source VCV Rack library. The plugins were based on specific mathematical models of chaotic behavior and topology, where the visual representation of such models is used either as a control or synthesis method (full source code). The current list of Axioma modules is the following:

The Bifurcator : control sequence generation according to the mapped positions on the bifurcation map. The positions are obtained based on iterations of a selected function type, that according to a bifurcation parameter value, it can lead to chaotic behavior;

Tesseract: output CV control based on the position of each vertex of a rotating Tesseract projected on a 2D space;

Ikeda: CV sequence generation based on the dynamic system map proposed by Kensuke Ikeda which describes a chaotic behavior within a specific parameter range.

Rhodonea: VCO with two oscillators defined by Rhodonea curves. It follows the idea of polygonal synthesis where the waves are created based on a projection of polar into cartesian coordinates.

Composition &

Production

----------------

As a musician, I have an interest in exploring different instruments, music genres and composition techniques. In the last decade I was part of live performances, recording sessions, compositions and EP/Album production in different music projects. The main projects are the following:

  • ATMOSFET : A solo electronic music project using modular analog synthesizers, DIY circuits and algorithmic synthesis/processing methods. I independently released a few EPs/albuns and several videos of live performances;
  • SINTODRAMA : An experimental music duo that focuses on a sonic mixture of acoustic (drums, voice) and electronic (modular synthesizers) sounds processed by real-time algorithmic DSP (Pd, SuperCollider);
  • NEBULA DOGS : Psychedelic Indie Rock band that composed, recorded and produced two full length albums. I played guitar and vocals in the recording sessions and live performances;
  • THE SALTY SEBASTIANS : A sonic exploration duo that brings an analog modulated palette of dubbed sounds, intertwined with world music ranging from Indian drones to Italian opera, with tools varying from a vinyl and tape player to interactive equipment, such as a modular synth or a groove- and shruti box;
  • RIO VALPES/UAPES : Home made electronic jamming duo creating soundtracks for amazonian adventures along the border between Colombia and Brazil;
  • KAWERNOMA : Abnormal growth of internal sounds.

Performances

----------------

Here is a list of recent sound-related performances:

  • [SOLO] Synthetic ecological destruction (2024): synthetic soundscape using analog synthesizes (from WORM Studios) inspired by amazonian ecosystems and their reaction to modern human interaction. Performed at Interrupción event at WORM by Cinema Colombiano;
  • [SOLO] Feedback crickets (2023): headphone-microphone feedback simulation of cricket sounds during Extratonal Infrastructure event #10;
  • [THE SALTY SEBASTIANS] Modulated dubbed live set (2023): Performative dj live set with analog synthesizers and acoustic instruments over a mix of analog media containing world music and beyond! Extratonal Infrastructure event #9;
  • [SOLO] BIRDS AGAINST THE MACHINE (2023): sound performance at Extratonal Infrastructure event #5 based on SuperCollider where a tropical bird soundscape fights to achieve an expected loudness over a chainsaw noise that masks their natural orchestra;
  • [SOLO] ATMOSFET live recap (2022): interactive live set with previous compositions accompanied by improvisation with external analog instruments;
  • [SINTODRAMA] ~ODO release concert (2022): live performance with new songs from the album release, using an interactive live set in SuperCollider accompanied by acoustic drums and sprayed odorants around the audience;
  • [SINTODRAMA] Metendo o Nariz onde não foi chamado (2020): multisensory performance combining sound and odor where the main concept was the sonification of the different odor molecules to create specific timbres and scales (SuperCollider), accompanied by acoustic drums and sprayed odorants around the audience;
  • [SINTODRAMA] Live Cinema - Enter the Void (2019): live sound interpretation of four scenes from the film “Enter the Void” by Gaspar Noé, using acoustic drum sounds combined with digital sound synthesis were played and processed in real time using live coding with SuperCollider;
  • [SINTODRAMA] Live at Itapema (2016): debut live performance containing the first three compositions of the duo, using DIY analog synth modules accompanied by drums with real time processing (Pd and Xbox Kinect sensor).

SuperCollider

Scripts

----------------

SuperCollider is an audio synthesis/processing platform that I have been using in sound performances, installations, compositions and also as an audio software development prototype tool. Here are a few examples of scripts:

-> ODOR MOLECULE SONIFICATION: GUI program script which converts IR spectrum measurements of odor molecules into additive synthesis components, and other features for sound sequence composition using different molecules

-> BIRDS AGAINST THE MACHINE: Performance script used to create a sound battle between birds and chainsaws.

-> SYNTHESIS OF LIFE: Game of life performance GUI script to be used in combination with Korg nanoKONTROL 2.

-> POLAR WAVE SHAPER: GUI-based script to create wavetable shapes based on drawings in polar coordinates.

-> SC WORKSHOPS: ongoing workshops that I ahve been creating to share knowledge about this amazing tool!

Platform

for

Extratonality

----------------

The Platform for Extratonality focuses on sonic (and neighboring) activities that reject distinctions between high and low, exceptional and boring, serious and pop. It streches the classical paradigms of music (balance, contrast, focus, movement, pattern, proportion, rhythm and unity) and expand them with conceptual, technical and performative principles from other disciplines. I am member of this group by participating and/or helping with the organization of conferences, performance evenings, radio shows and workshops.

Research & Work


This section provides brief descriptions and links related to my experience in different research/engineering fields. Here is a technical resume concerning education, work and publications.

----------------

Acoustics

----------------

My initial experience in the field of acoustics was at LVA-UFSC where I worked with numerical vibro-acoustics and psychoacoustics. Later, while working at AIP-TUM, I spent two semesters as a teaching assistant in a course about technical acoustics. For two years (2018-2020), I worked at Hexagon-FFT in the development, support and maintenance of the Actran Software Suite, as well as in acoustic consultancy projects for different industrial areas.

----------------

Audio

----------------

After my Master studies, I spent 3 years working with audio signal processing research projects related to the development of auditory nerve models, both at LVA-UFSC and at AIP-TUM (where I also worked as a teaching assistant in the course of of signal processing for audio technology).

In the last years (2021 - 2024), I worked as an Audio DSP Developer for SoCs (System on a Chip) at Absolute Audio Labs, where I was responsible for software design, validation and tuning of speech and music applications with a main focus on people with hearing loss (firmware for earbuds and hearing aids).

Outro


----------------

Varia

----------------

Varia is a Rotterdam based initiative, which started in 2017 from the need to open up their members' practices and organise ad-hoc public or semi-public moments among different configurations; at its core it aims at developing critical understandings of the technologies that surround us. Varia experiments with tools for building physical and digital infrastructures in a collective way. I am a member of this collective with participation in event organization and support as well as other internal activities such as space and server maintenance.

----------------

Web apps

----------------

There are a few open source simple web apps (manly for desktop browser use, GUI design not extended for mobile browsers) that I created to be used as tools for acoustic design:

Parabolic microphone gain: Graphical tool for estimation of microphone acoustic amplification when attached to a parabolic dish. The estimated response is for an incient plane wave reaching the dish at 0 degrees. One can set up the dimensions for desining such a parabolic dish for an expected amplification.

Coupled acoustic resonators: Graphical tool for estimation of acoustic response when designing acoustic resonators (Helmholtz resonators). One can obtain impedance and absoption values along the audible frequency range, based on specific requested dimensions and material properties. One can also use the tool to design coupled arrays (up to 3 resonators)

Waves on canvas: Graphical tool for visualization of acoustic fields created by combining different types of point sources (monopole, dipole, quadrupole). It can be used as a teaching tool to show in an interactive way how different sources play a role in the acoustic field with respect to amplitude, phase, frequency and direction.

----------------

Virtual reality

----------------

Rebocando o Pavilhão Philips : project from SINTODRAMA where a multichannel sound piece was created to be presented in a virtual environment through an Oculus app. Apart from being part of the multichannel sound composition, I was also the main developer of this app.
