hello everyone, this is my first post. I hope someone out there has the answer…

I want to read the byte data from an MP3, URLStream. I’ve managed to get the ID3 info by using readUTFBytes and using the corresponding byte positions, but I havent found where the framesync, version, description, bitrate, ect., are located. I am particularly interested in the bitrate. if I understand correctly, that information should be clumped together in 4 bytes.

anyone have any ideas / experience with this?

thanks in advance.
