Olá pessoal…
Estou construindo um pequeno player utilizando a biblioteca chamada JLayer, porém estou com dúvidas para parar (stop) a execução do áudio?
Alguém pode me dar alguma sugestão?
Grata!!!
Bom fiz um player uma vez utilizado essa biblioteca http://www.javazoom.net/mp3spi/sources.html e adicionei o jar jl1.0 que está na pasta lib a classe ficou assim e para parar o mp3 usei o close() como pode ser observado no codigo abaixo

Muito Obrigada!!!
Mas, seria possível voce também anexar o código da classe FiltrarArquivo, por favor.
Agradeço!!!
obs. essa classe não é minha!
