Title in Portuguese
UTILIZAÇÃO DA TRANSFORMADA KARHUMEM-LOEVE EM SÍNTESE DE TONS MUSICAIS
Keywords in Portuguese

Abstract in Portuguese
Sinais podem ser amostrados, armazenados e reproduzidos por computadores digitais. Adicionalmente, sinais podem ser analisados de modo que formas comportadas de sua representação possam ser extraídas, economizando o espaço de memória necessário para o armazenamento. A transformada de Fourier tem sido tradicionalmente utilizada para este fim. Este trabalho trata da utilização da transformada Karhunen-Loeve como método alternativo de representação de tons musicais, possibilitando grande economia de recursos computacionais comparada com a transformada de Fourier.

Abstract in English
Signals can be sampled, stored and played back by digital computers. Furthermore, signals can be analized in such a way that compressed forms of their representation can be extracted, reducing the amount of memory needed to store them. The Fourier transform have been traditionally used in this way. This dissertation deals with the use of the Karhunen-Loeve transform as an alternative method of representing a particular and dynamic signal, the musical tones, allowing bigger savings of computing resources, as compared to the Fourier transform.
