Subject: Quick VBR calc question

Quick VBR calc question

From: Scott Bronson <>
Date: Wed, 12 Feb 2003 15:39:30 -0800 (PST)

How does Rockbox calculate the average bit rate of the MP3
so quickly? Within 1/2 second of hitting play, what looks
to be a fairly accurate VBR appears on the WPS.

My desktop machine either says that it's a 64kbit file (since
most songs start with silence and it doen't update the display
after the first frame) or takes two seconds or so to scan over
the song.

Where's the magic? :) Thanks,
