Re: Koji plejer daje najprecizniji zvuk?

interesantno je ?ta pi?e na FAQ foobara2000

Q: Does foobar2000 sound better than other players?
A: No. Most of ?sound quality differences? people ?hear? are placebo effect (at least with real music), as actual differences in produced sound data are below their noise floor (1 or 2 last bits in 16bit samples). Foobar2000 has sound processing features such as software resampling or 24bit output on new high-end soundcards, but most of other mainstream players are capable of doing the same by now.

Mnogo bolji zvuk nego media pleyer koji nevidjeno sminka, kao i nove 5.x verzije Winampa.

Jedan izvor kaze ovo:

Quote:

Since what the MP3 standard really defines is a decoder, there should be no such thing as a better or a worse MP3 decoder. As long as a decoder is accurate, it'll output the expected quality.

All the most popular decoders these days output accurate enough streams. These include:
Winamp's FhG decoder
mpg123, probably one of the most popular decoders, also used in foobar2000, Otachan's winamp plugin, LAME and countless other MP3 players
MPAdec, a very accurate decoder based on mpg123
Apollo, the most mathematically accurate decoder
MAD, another very precise GPLd MP3 decoder
A MAD input-plugin for WinAmp is available in this HA thread

Using any of the above should be enough for all purposes. Quality differences among them are insignificant.

Drugi izvor kaze da ipak postoji razlika, ali cini mi se da su vezane samo za bite, tj dinamicki opseg, ne za frekvencije, tj bojenje signala.

The results for Apollo 37zm 24-bit output are RMS level 7.169?10−10 and maximum difference 1.192?10−7.

For comparison, the same values for the latest MAD decoder (MPEG Audio Decoder 0.15.1b) built with accuracy optimizations enabled and 24-bit output without dithering are RMS level 8.804?10−8 and maximum difference 4.768?10−7. The difference is quite obvious and favorable to Apollo: RMS level is over a hundred times the one produced by Apollo 37zm and the maximum difference is four times the one by Apollo (interestingly the results for MAD 0.11.4b seem to be somewhat better than for the latest one but they are still worse than Apollo's). Actually, the maximum difference of Apollo's output is the smallest possible deviation in 24-bit data, the only smaller possible value would be zero. This means that at any time, Apollo's output is either exactly the same as the reference output or differs from it by the smallest unit expressible in 24-bit data. Of course, this only goes for the provided test signal, but it should give some picture about the sound quality.

Koliko ja mogu da zakljucim iz ovoga, razliciti dekoderi, ne daju isti dinamicki opseg na izlazu i imaju razlicite najmanje razlike nivoa, tipa jedan ocitava razlike od 0.01 db a drugi 0.04 db , tj. jedan dekoder kao sto pise gore u tekstu 4 puta preciznije ocitava razliku u nivoima unutar pesme.

Bas me zainteresovalo ovo pa sam se bacio na istrazivanje :)

Kad sam otvorio post mislio sam da je besmislen i da razlika uopste ne postoji, ali izgleda ipak postoji, sad, kolika je objektivno i koliko je cujna subjektivno to je vec pitanje.

Word! :) najbolja verzija winamp-a :)

Re: Koji plejer daje najprecizniji zvuk?

ovo pere

FhG decoder
Fraunhofer MPEG Layer-3 Audio Decoder

i samo mu stavis najveci priority u audio drivers i pusta u winampu

apollo sad probam

Re: Koji plejer daje najprecizniji zvuk?

znam da sam malo zakasnio,
ali evo da zabiberim pricu, posto je tema interesantna zbog toga sto se svakodnevni materijal koji se preslusava ne moze bas pustati iz nekog editora [ili sekvencera] a treba nam koliko toliko dobar zvuk, pa makar bile to i mp3-ojke, koje ljudi sve bolje grebuju [valjda su se edukovali].
probao sam mnoge male playere foobar, billy, winamp...
i ipak se winamp sa celom svojom dugogodisnjom istorijom najbolje pokazao ali naravno potrebno je uvek [redovno] skidati najnoviju verziju jer su poboljsanja svaki put tolika da se stvarno vidi da neko radi na njima . evo samo nekoliko poslednjih verzija:
http://winamp.com/player/version_history.php
skoro sam download-ovao novi winamp 5.32 i ima podrsku za 24-bit output, sto je drzalo foobar koliko toliko u trci.
nije lose ni isprobati varijantu DSP bridge za winamp [moze i za foobar] kojim se mogu koristiti VST instrumenti kroz koje ce proci zvuk i time ga definisati drugacije [bolje]. nisam stigao da procitam thread, ne znam da li je neko pisao o tome, ali vredno je pomena.
