Processamento de Áudio em Microcontroladores Simples

Abstract

Este artigo descreve o desenvolvimento de dispositivo eletronico capaz de realizar processamento de audio em hardware utilizando microcontroladores de baixo custo. Sao descritos hardwares para a captacao e amplificacao de audio. Demonstra como o microcontrolador deve receber os sinais de audio, como deve processa-los e como deve fornecer os dados de saida. O sinal processado foi enviado atraves da saida PWM para o amplificador e ao alto falante. Para comprovar o adequado processamento e a inteligibilidade dos audios processados, testes com voluntarios foram realizados. Os testes demonstraram 100% de inteligibilidade, comprovando a eficacia do metodo utilizado.
