Vodič do savršenog zvuka
DISCLAIMER - Ovaj vodič pisan je u najboljoj namjeri i obrađuje temu izrade zaštitnih kopija legalno kupljenih audio CDa i njihovog arhiviranja na hard disk računala.
SADRŽAJ EAC options
DRIVE options
Compression
UVOD Digitalizacijom zvuka postalo je vrlo jednostavno napraviti identičnu (1:1) kopiju audio CDa popularnim 'ripanjem'. Nažalost tako dobijena kopija iako kvalitetom identična originalu ima dva glavna nedostatka.
Prvi je veličina same datoteke koja zauzima previše mjesta na disku a drugi je nedostatak bilo kakve podrške za tagove u izripanom WAV zapisu što ga čini praktično neupotrebljivim za arhiviranje i katalogiziranje.
Na prvi pogled rješenje oba problema nameće se samo po sebi u vidu MP3 formata. Svoju je popularnost stekao zahvaljujući odličnom omjeru veličine datoteke i kvalitete zvuka i ovisno o stupnju kompresije nudi veliku uštedu prostora. Uz to MP3 ima odličnu podršku za tagove te ga je lako katalogizirati. Nažalost ima i jednu veliku manu a to je da je MP3 tkz. lossy codec odnosno koristi način komprimiranja s gubitkom i zato komprimirana datoteka NIJE identična originalu. Razlika između originalnog i MP3 zapisa proporcionalno dolazi do izražaja ovisno o kvaliteti opreme na kojoj se sluša takav audio zapis. Uz to svako ponovno rekodiranje takvog zapisa dodatno degradira kvalitetu zvuka.
Da bi dobili najbolje iz oba svijeta odnosno identičnu kopiju audio zapisa koja zauzima manje diskovnog prostora od originalnog zapisa a uz to ima i mogućnost katalogiziranja odnosno podršku za tagove moramo se okrenuti tkz. losseless codecima.
Na Hydrogenaudiovoj listi najpopularnijih losseless codeca uvjerljivo vodi FLAC, slijedi ga WavPack i na kraju APE (Monkey's Audio). Svi losseless codeci su zbog svoje bez gubitne naravi kvalitativno isti i u konačnici daju identičnu kopiju originalne datoteke tako da se međusobna usporedba može raditi samo po brzini kodiranja/dekodiranja, 'trošenju' sistemskih resursa i velični izlazne datoteke. Razlike između navedenih codeca tokom vremena svedene su na nijanse i svaki od njih če dobro obaviti svoj posao. Ipak ovaj vodič, iako je univerzalno primjenjiv i na ostale navedene codece, orijentira se na FLAC.

INSTALACIJA i OSNOVNO PODEŠAVANJE
- FLAC - (Free Losseless Audio Codec) je Open Source format za komprimiranje bez gubitka koji uz 30-50% manju veličinu datoteke daje IDENTIČNU kopiju audio zapisa. Popularnost je stekao baš zbog svoga 'otvorenog' karaktera i podrške za razne operativne sisteme: Windows, UNIX (Linux, BSD, Solaris, OS X, IRIX), BeOS, OS/2, i Amigu, tako da je defacto postao neslužbeni standard za losseless kompresiju a u zadnje vrijeme dobija i sve veću podršku proizvođača hardwarea. Iako ne daje najbolju stopu kompresije ni brzinu kodiranja prednost mu je izuzetna lakoća dekodiranja komprimiranog zapisa neovisno o stupnju kompresije i smiješno mala potrošnja resursa što ga čini pogodnim i za slabije strojeve. Instalacija FLACa je trivijalna. Skinite i pokrenite FLAC for Windows with installer sa službene stranice i on će obaviti sav posao. Ako ne želite automatsku instalaciju koja instalira FLAC frontend i dodatne plugine za winamp, neru... itd, skinite zip arhivu u kojoj je samo codec i otpakirajte je u folder po izboru.
- EAC - (Exact Audio Copy) je besplatni i po mnogima najbolji alat za sigurno ripanje audio CDa. Kompleksan program sa hrpom opcija specijaliziran za kreiranje DOSLOVNO savršenih kopija i iako sama instalacija EACa nije komplicirana dodatno podešavanje zna zbunit početnike baš zbog velikog broja opcija i zato ćemo ga detaljno proći. Prvo skinite i instalirajte Exact Audio Copy V0.95 beta 4 sa službene stranice.
Po završetku instalacije dočekat će nas EAC setup wizard:
kojega ćemo preskočiti i krenuti na ručno podešavanje programa.

The Geek Wants OUT
by Ernest Cline
At first glance
I probably appear to be a somewhat ordinary,
somewhat average looking fellow.
Calm, harmless, at ease.
But this is by design.
You see, it is through decades of research and rigorous training that I have crafted this façade of normalcy.
And now, through intense concentration,
I am able to function in a social setting.
I can speak at length with educated people about
pertinent matters of public importance,
such as literature,
or the current political climate in Europe.
I am capable of conversing with you
without ever revealing that just underneath the surface
of this manufactured veneer
there hides an altogether different person.
A monster, some might say.
My alter-ego.
He is the opposite of the image I project.
He is the antithesis of Cool.
He is the LAST person you want to get trapped in a conversation with.
He is The Geek.
The obsessive science fiction movie watching,
comic book collecting,
Monty Python dialogue memorizing,
Dungeons and Dragons playing GEEK
that I struggle daily to keep hidden from the world.
But The Geek Wants Out.
He want to talk to you.
He wants to give you his doctoral dissertation on why
The Adventures of Buckaroo Banzai Across the 8th Dimension
is the greatest fucking film of all time!
He wants to bitch slap you because
you’ve never seen Big Trouble in Little China.
What? Have you been living in a fucking cave?!
He wants to kick your ass in Star Wars Trivial Pursuit.
And he will.
Because he’s a fucking Geek.
And he wants his toys.
He wants the complete set
in mint condition,
still in the box.
He wants every item on the planet that is even remotely related to Ultraman.
Because Ultraman is Airwolf!
He could give a squirt of piss
about sports or politics or rhetoric.
Such things are of no consequence to him.
What matters is the release date of the next Lord of the Rings movie!
You see, The Geek can’t wait.
The Geek has no patience.
He wants what he wants when he wants it.
And all he wants is stupid shit!
He wants his own Tardis.
He wants his own light saber.
He wants to buy a DeLorean and he wants to drive it 88 miles per hour.
He wants movies.
He wants to see the Director’s Cut.
He wants the impossible to find Japanese bootleg with
6 minutes of never-before-seen footage.
He wants to watch Blade Runner. Again.
He wants to watch Brazil. Again.
He wants to watch A Clockwork Orange.
Again and Again!
But I deprive him of these things, as best I can,
until I can no longer ignore his voice
screaming in my head.
I am Jekyl. He is Hyde.
I am Bruce Banner. He is the Hulk.
Especially the Hulk from issues #272 to #378.
But no longer!
I am putting a stop to all this nerdy shit right now!
I’m an adult, for Christ’s sake!
And this body isn’t big enough for the both of us.
One of us has to go, and it’s gonna be him.
I banishing the Geek forever to the Phantom Zone,
just like in Superman II !
Because, in the end –
there can be only one.
