Normalize V1.10 - Documentation of a sort...
Hello all,
It's me again... That crazy hacker from New Jersey. This is the latest
release of NORM.EXE a program to normalize the data contained in a voice
capture file produced by the Farpoint Digitized (A.D. Jones) Well, the
program has gone through quite a bit of modification and I can't really
say it works any better. The algorythm has been rewritten on the Bit level
as opposed to the Byte level, files of any size can be processed, and NORM now
even accepts parameters! (Gee!) Before I go any further I guess I had better
explain a little about how NORM operates...
As you know, the voice file is just a Bit-Stream of data recorded in file
format. Due to interference, improper voltage, or just plain white noise the
digitizer tends to pick up little Bits where there should be no little Bits.
Norm goes through the file in Packets (1 to 10 Bytes in length) and sums the
number of ON Bits. NORM then divides this by the total number of Bits (Smart
this Norm!) and obtains the percentage of ON Bits. This is then checked
against the Drop Ratio. If the percentage is lower than the Drop Ratio, NORM
blanks out the entire Packet leaving it static free. If it is higher, NORM
lets the Packet pass and goes on.
This revision of NORM allows the user to set the Packet Size (1 to 10 BYTES)
and the Drop Ratio to His/Her own standards... These values affect the amount
of erroneous bits to strip from the file, as well as the consideration of which
bytes are erroneous. Experiment with the values to find those to suit your
particular needs. The defaults are 8 Byte packets with a 5% (0.05) Drop Ratio.
Should you have any questions/comments I may be reached on the INTERLINK or
SMARTNET Pascal conferences or my own board 530 Hudson Street - ΣΦE in Wyckoff,
New Jersey, (201) 891-3721 12/24/9600 USRobotics HST 24Hrs/7Days. Address any
questions to Bruce Walter. I encourage any remarks/ideas.
I hate to get legalese on you all, but at least I put it at the end of the
file!
THIS PROGRAM IS PROVIDED AS IS. THE AUTHOR IS NOT RESPONSIBLE FOR IT'S USE,
MISUSE, OR ANY DAMAGES CAUSED DUE TO TAMPERING OR IMPROPER USE.
There, short & sweet. Have fun all!
