In this work the audio spectral coder methodology was studied in order to achieve a real-time implementation of the decoder. This work followed two main steps: the study of an integrated solution for Pc developed in C++, and the development of the decoder in C. (...); Neste trabalho faz-se o estudo de uma solução completa de codificação de áudio de alta qualidade designada por ASC ("Audio Spectral Coder"), impl...
