1st paragraph

MPEG is not a single standard, but rather a "family" of standards defined by the Moving Picture Experts Group, which was formed in 1998(it should be 1988)

Frames Per Second

The formula for calculating the MP3 frame size is incorrect. It currently shows:
FrameSize = 144 * BitRate / (SampleRate + Padding)
It should be:
FrameSize = (144 * BitRate / SampleRate) + Padding

There should also be mention of integer truncation in determining the frame size.
The next paragraph says that the "total size of each frame will be 417.96 bytes...".
This is really not correct. The size of unpadded frames will be 417 bytes and padded
frames 418 bytes. There will never be a frame with 417.96 bytes!
