URB is a research project designed to collect and store raw data from soundscapes analysis. This paper presents a survey about using URB based on the analysis of work developed by several artists, focusing on the description of their creative process and outcome. By comparing the processes and statements of each artists, the authors identified diverse systematic approaches to reinterpreting raw data provided by urban soundscapes, raising questions about the artistic outcomes vs original sound sources. Furthermore, some considerations are inferred about the artistic relevance of using this process in the creation process.

Este artigo apresenta os resultados obtidos da exploração dos vetores de características gerados de técnicas de word embedding (especificamente word2vec e wang2vec) a partir de um banco de textos na ordem do bilhão de tokens em comparação com os gerados a partir de bancos pequenos na ordem de dezenas de milhar, na aplicação de detecção de discurso de ódio na língua portuguesa. Dando continuidade às pesquisas desenvolvidas por outros autores no Brasil e em Portugal, e aproveitando os recursos e sugestões por eles disponibilizados, conseguiu-se uma melhora de até 2,5% na taxa de acerto na classificação, em relação ao estado da arte em língua portuguesa.

In this paper we present the motivations, processes and results of two experimental music pieces. Two approaches as how the soundscape can catalyze direct inspiration and raw material to the creation of music. By describing the processes and results of public presentations, we identified approaches reinterpreting raw data in music composition. The first work is a 9 minute piece for tape, small orchestra and improvisation ensemble. The main purpose was to capture the soundscape identity around the concert hall and transform it in a music piece. The second work is a 6 minute piece for 4 channel (quadriphonic) tape. The purpose of this piece was to experiment a more purist approach to create music with the data information taken from a random soundscape of a random full day from an urban space also chosen randomly. Furthermore, some considerations are inferred about the artistic relevance of using this approach, raising questions about the musical outcomes vs. original sound sources.
