Summary: In this paper we present and dicuss a new algorithm for the compression of audio signals in which we are currently working. Backward-adaptive quantization, a fundamental innovation that differentiates this from other perceptual audio coders, is justified for its multiple advantages. We conclude with a discussion of some issues related to the design of the various components of the coder we are developing.

A utilização de quantização retro-adaptada, uma inovação fundamental que diferencia este de outros codificadores perceptuais de áudio, é justificada pelas suas múltiplas vantagens. Concluímos com uma discussão de algumas questões relacionadas com o projecto dos vários componentes do codificador que estamos a desenvolver.UA Editora2001-01-01T00:00:00Zjournal articleinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://proa.ua.pt/index.php/revdeti/article/view/18135oai:proa.ua.pt:article/18135Eletrónica e Telecomunicações; Vol 3 No 4 (2001); 362-364Eletrónica e Telecomunicações; vol. 3 n.º 4 (2001); 362-3642182-97721645-0493reponame:Repositórios Científicos de Acesso Aberto de Portugal (RCAAP)instname:FCCN, serviços digitais da FCT – Fundação para a Ciência e a Tecnologiainstacron:RCAAPenghttps://proa.ua.pt/index.php/revdeti/article/view/18135https://proa.ua.pt/index.php/revdeti/article/view/18135/13038Rodrigues, João ManuelTomé, Ana Mariainfo:eu-repo/semantics/openAccess2022-09-26T11:00:24Zoai:proa.ua.pt:article/18135Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireinfo@rcaap.ptopendoar:https://opendoar.ac.uk/repository/71602025-05-28T10:30:01.480745Repositórios Científicos de Acesso Aberto de Portugal (RCAAP) - FCCN, serviços digitais da FCT – Fundação para a Ciência e a Tecnologiafalse
