Mp3 audio frame length calculated incorrectly?

It seems as if the mp3 frame length is calculated incorrectly (off by about
a factor of two). All the equations I've seen online (and I've verified
that they work on the files I'm testing) use:
144000 * bitrate / sampleRate + ispadded
whereas TagLib::MPEG::Header uses
72000 * bitrate / sampleRate + ispadded
Am I missing something, or is this incorrect? If it's a mono/stereo issue,
shouldn't the header account for this or is the user supposed to multiply by
2 & subtract 1 if it's padded?
