Olá pessoal,

minha dúvida é bem simples tenho um player de MP3 e gostaria de exibir o bitrate da musisca é possivel? se sim como?

valew pessoal ...

No Flash 8 (AS 1/2.0) não tem como ser feito a não ser que você pegue o tamanho do arquivo, tempo do som e tralalas e calcule manualmente o bitrate, acho que assim é possivel mas posso estar muito errado sobre isso

Já com AS3 e Flash 9 é possivel... aqui uma classe de um MP3 Player em Flash 9

nossa cara que código assustador ...

Então de flash naum manjo muito essas paradas de classes ... mas eu posso importar essa classe neh ???

E pelo q vi dessa classe ela é um player neh ?
