Скачать или смотреть Federico Russo: MIDI Controlled Audio Effects – Real-Time Reshaping of the Audio Signal

Csound 30 Conference, 25-27 November 2016, Maynooth University.

Explanation of the general structure of the instrument
It is a MIDI controlled audio effect, which is divided into 4 modules. Each module processes the audio signal in different ways, except for the audio input, which is needed to get the source signal. The audio signal flows trough the modules thanks to a dry/wet system based on internal busses.

Explanation of each module of the instrument (code order)
-Module 1: audio input.
-Module 2: audio shift, warp and freeze, separated for spectral amplitudes and frequencies, controlled via MIDI. Implemented with an LFO controlled binaural movement.
-Module 3: audio resynthesis, using a vocoder-like structure, with selection of waveform to blend the incoming signal with.

Explanation of the workflow
The instrument was created module by module, testing the correct functionality each time a line of code was written. Creative use of references was applied, looking at the use that other developers had of opcodes in their instruments, to understand their functions and possible applications in the instrument.

Applications
The instrument finds its usefulness in cinematic sound effects for voices and non tonal based music, due to its random behaviour from the pvsfreeze opcode (the freeze of the frequencies is triggered by the keyboard).

Federico Russo began to study the electric bass when he was 13 under Andrea Grossi, enrolling in the courses of the Accademia Nova of Rome.
He also studied cello, with the concert performer and professor of the Istituto Superiore di Studi Musicali Gaetano Braga of Teramo Matteo Scarpelli.
During his studies, he also played, composed and arranged music with his band, Libra: the band played in some of the more important stages of the Roman scene, but also in other cities thanks to the promotional tour for the album Sottopelle (Volcan records), this landed the band on MTV new generation.
After that he started to study sound engineering at the Saint Louis college of music in Rome, where he founded with two colleagues the One Got Fat Collective for experimental electronic music and videos. In addition to that, during the sound engineering studies he met the experimental music composer Luca Spagnoletti, who introduced him to audio programming, specially the object programming of Max msp.
