Subject: peak meter log problem
From: Andreas Stemmer (Andreas.Stemmer_at_web.de)
Date: 2002-09-29


I had a short look at the original Archos peak meter recently, it has 16
bars only. Therefore it is incredibly easy for the Archos programmers to
calculate the log from a 16 bit number for the dBfs scale: search the
highest bit and fill the bars from left to the bar with the according
number. Finished!
Perhaps this helps a little bit for the peak meter design, but of
course, this reduces the resolution of the display.
