\"Kako<\/a><\/noindex>
\nVjerojatno je skoro svima poznato da je izlaskom Windows Vista 2007. godine, a potom i svih sljede\u0107ih verzija Windowsa, zvu\u010dni API DirectSound3D uklonjen iz Windowsa, a umjesto DirectSounda i DirectSound3D po\u010deli su se koristiti novi API-ji XAudio2 i X3DAudio. Kao rezultat toga, u starim igrama postali su nedostupni zvu\u010dni specijalni efekti EAX (zvu\u010dni efekti okru\u017eenja). U ovom \u010dlanku \u0107u objasniti kako vratiti taj stari DirectSound3D\/EAX u sve stare igre koje podr\u017eavaju ove tehnologije na Windowsu 7\/8\/10. Naravno, iskusni gameri to ve\u0107 znaju, ali mo\u017eda \u0107e ovaj \u010dlanak nekome biti koristan. <\/p>\n

Stare igre nisu oti\u0161le na otpad povijesti, naprotiv, u\u017eivaju ogroman interes kako od strane starije generacije, tako i mla\u0111e. Stare igre izgledaju bolje na modernim ekranima visoke razlu\u010divosti, za mnoge igre izlaze modovi koji pobolj\u0161avaju teksture i shadere, ali s zvukom su isprva imali problema. Izlaskom sljede\u0107e generacije Windows Vista, nakon Windows XP, Microsoftovi programeri su smatrali da je DirectSound3D moralno zastario \u2013 imao je ograni\u010denje na 6-kanalni zvuk, nije podr\u017eavao kompresiju zvuka, bio je procesorski ovisan i zato mu je zamjena postao XAudio2\/X3DAudio. A s obzirom na to da je tehnologija EAX tvrtke Creative bila neovisno API, kao \u0161to je nekada bio A3D tvrtke Aureal, ve\u0107 samo pro\u0161irenje DirectSound3D \u2013 zvu\u010dne kartice tvrtke Creative na\u0161le su se izvan igre. Ako se ne koriste posebni softverski omota\u010di, prilikom igranja starih igara na Windows 7\/8\/10 menu stavke koje uklju\u010duju EAX ne\u0107e biti aktivne. A bez EAX zvuk u igrama ne\u0107e biti toliko bogat, prostoran, pozicioniran.
\n<\/a><\/noindex>
\nKako bi rije\u0161ila ovaj problem, kompanija Creative je razvila wrapper program ALchemy, koji preusmjerava pozive DirectSound3D i EAX u cross-platform API OpenAL. Me\u0111utim, ovaj program slu\u017ebeno radi samo sa zvu\u010dnim karticama kompanije Creative i to ne sa svim modelima. Na primjer, moderna karta Audigy Rx sa hardverskim DSP procesorom CA10300 slu\u017ebeno ne funkcioni\u0161e. Za vlasnike drugih zvu\u010dnih kartica, kao \u0161to je integrisana Realtek, potrebno je koristiti jo\u0161 jedan softverski drajver Creative Sound Blaster X-Fi MB, koji ko\u0161ta novac. Mo\u017eete poku\u0161ati i sa originalnim programom 3DSoundBack, ali on nije dovr\u0161en od strane kompanije Realtek \u2014 ostao je u beta verziji, radi lo\u0161e i ne sa svim \u010dipovima. No, postoji bolji na\u010din, jednostavniji za kori\u0161tenje i besplatan. <\/p>\n

Prvi na\u010din<\/h2>\n

\nPo\u010dnimo sa zvu\u010dnim karticama kompanije ASUS. Zvu\u010dne karte kompanije ASUS DGX\/DSX\/DX\/D1\/Phoebus temelje se na \u010dipovima C-Media, a \u010dak i \u010dipovi ASUS AV66\/AV100\/AV200 \u2014 to su sve iste preimenovane \u010dipove C-Media. U karakteristikama ovih zvu\u010dnih kartica pi\u0161e da podr\u017eavaju EAX 1\/2\/5. Svi ovi \u010dipovi su naslijedili od svog prethodnika CMI8738 DSP modul hardverski EAX 1\/2, EAX 5 je ve\u0107 softverski.<\/p>\n

Vlasnicima kartica serije Xonar je jako sretno, svi su vidjeli dugme GX na panelu drajvera, ali mo\u017eda ne znaju svi \u0161to ono radi. Poka\u017eem na snimcima programa AIDA64, ovako izgleda kartica DirectX zvuka kada dugme nije aktivno i kod vlasnika integrisanih zvu\u010dnih kartica Realtek u Windows 7\/8\/10:<\/p>\n

\"Kako
\nSve zvu\u010dne baferi su jednaki nuli, svi API su neaktivni. A odmah nakon uklju\u010divanja dugmeta GX vidimo<\/p>\n

\"Kako
\nDakle, vrlo je prakti\u010dno \u2014 ne morate pokretati dodatne programe poput Creative ALchemy i kopirati datoteku dsound.dll u svaku mapu s igrom. Postavlja se veliko pitanje za\u0161to to nije u\u010dinila tvrtka Creative u svojim upravlja\u010dkim programima? \u0160tovi\u0161e, u svim novim modelima Sound Blaster Z\/Zx\/AE ne koristi hardverski DSP procesor za obradu EAX-a, ve\u0107 to \u010dini softverski putem upravlja\u010dkog programa prema pojednostavljenim algoritmima. Neki ljudi smatraju da je softverska obrada zvuka dovoljna, jer su moderne CPU mnogo sna\u017enije od procesora zvu\u010dnih kartica prije 10 godina koje su hardverski obra\u0111ivale zvuk. To nije to\u010dno. CPU je optimiziran za obradu x86 instrukcija, dok DSP br\u017ee obra\u0111uje zvuk od centralnog procesora, kao \u0161to grafi\u010dka kartica br\u017ee provodi rasterizaciju nego CPU. Centralni procesor \u0107e biti dovoljan za jednostavnije algoritme, ali kvalitetna reverberacija s vi\u0161e izvora zvuka oduzet \u0107e previ\u0161e resursa, \u010dak i sna\u017enom CPU-u, \u0161to \u0107e rezultirati smanjenjem FPS-a u igrama. To je ve\u0107 priznala tvrtka Microsoft i ponovo je omogu\u0107ila podr\u0161ku za obradu zvuka DSP procesorima u Windows 8, kao i tvrtka Sony koja je dodala poseban \u010dip za obradu 3D zvuka u svoju konzolu PS5.<\/p>\n

Drugi na\u010din<\/h2>\n

\nOva opcija je pogodna za korisnike ugra\u0111ene zvu\u010dne kartice na mati\u010dnoj plo\u010di, kojih je ve\u0107ina. Postoji takav projekt DSOAL<\/a><\/noindex> \u2014 to je softverska emulacija DirectSound3D i EAX-a putem OpenAL (OpenAL mora biti obvezno instaliran u sustavu) koja ne zahtijeva hardversko ubrzanje. Ako va\u0161a zvu\u010dna \u010dip ima neke hardverske funkcije za obradu zvuka, one \u0107e se automatski koristiti. Program radi tako dobro da je EAX radio sa mnom u svim starim igrama gde postoji oznaka EAX u pode\u0161avanjima. Ovako izgleda prozor AIDA64, ako kopirate datoteke DSOAL u mapu programa:<\/p>\n

\"Kako<\/p>\n

Ako se to nije dogodilo i imate sliku kao na prvom snimku ekrana, zna\u010di da izvorni Windows dsound.dll <\/b>ne dopu\u0161ta presretanje API-a, kao \u0161to je to bio slu\u010daj u mom slu\u010daju. Tada \u0107e pomo\u0107i ovakav na\u010din \u2014 potrebno je pokrenuti neki Windows Live-CD i ukloniti datoteku dsound.dll<\/b> ne bez pomo\u0107i alata Unlocker (prije toga napravite kopiju za slu\u010daj povratka) iz direktorija C:WindowsSysWOW64<\/b> i umjesto nje zapisati one dsoal-aldrv.dll<\/b> i dsound.dll<\/b>. U\u010dinila sam to i kod mene su i Windows i sve igre radile bez problema, \u010dak je i zgodnije \u2014 ne trebate svaki put kopirati te datoteke u mape s igrama, a u najgorem slu\u010daju, mo\u017eete ih vratiti natrag. dsound.dll<\/b> Istina, ovaj na\u010din \u0107e odgovarati ako ne koristite druge zvu\u010dne kartice ASUS ili Creative, jer \u0107e vam u tom slu\u010daju DirectSound3D uvijek raditi samo preko DSOAL-a, a ne preko izvornih drajvera ili ALchemy.<\/p>\n

Mo\u017eete poslu\u0161ati DSOAL u ovom videu:<\/p>\n

\r\n \"Pogledajte\r\n
<\/div>\r\n <\/div><\/center><\/p>\n

\u2192 Preuzmite gotovu biblioteku posljednje verzije mo\u017eete skinuti odavde<\/a><\/noindex><\/p>\n

Uspore\u0111uju\u0107i kako EAX zvu\u010di na razli\u010ditim zvu\u010dnim karticama, s iznena\u0111enjem sam otkrila da na ugra\u0111enom Realteku EAX zvu\u010di bolje nego na Asusima ili na mojoj Audigy Rx. Ako pro\u010ditate tehni\u010dke podatke, gotovo svi Realtek \u010dipovi podr\u017eavaju DirectSound3D\/EAX 1&2. Pokrenuv\u0161i AIDA64 pod Windows XP, mo\u017ee se vidjeti:<\/p>\n

\"Kako
\nIspostavilo se da Realtek, za razliku od ASUS i Creative zvu\u010dnih kartica, podr\u017eava i neki I3DL2 (nije u svakom Realtek tehni\u010dkom dokumentu to pisano). I3DL2 (Interactive 3D Audio Level 2) je otvoreni industrijski standard za 3D interaktivni zvuk, to je pro\u0161irenje za DirectSound3D za rad s reverbom i okluzijom. U na\u010delu, to je analogija EAX-u, ali zvu\u010di ugodnije \u2014 ugodniji reverb u igrama koraka, kada lik tr\u010di kroz pe\u0107inu ili dvorac, realisti\u010dniji zvuk prostornog zvuka u prostorijama. Dakle, ako stara igra radi na Windows XP, igram samo na XP jer se nadam da \u0107e zvu\u010dni engine mo\u0107i iskoristiti I3DL2. DSOAL, iako je otvoreni projekt i svatko ga mo\u017ee unaprijediti, nikada ne\u0107e mo\u0107i iskoristiti I3DL2 jer OpenAL ne radi s I3DL2, ve\u0107 samo s EAX 1-5. No, postoji i dobra vijest \u2014 po\u010dev\u0161i s Windows 8, I3DL2 je uklju\u010den u biblioteku XAudio 2.7.<\/a><\/noindex>Dakle, zvuk u novim igrama pod Windows 10 bit \u0107e bolji nego pod Windows 7.<\/p>\n

I na kraju, \u017eelim naglasiti da su sve te tehnologije 3D zvuka razvijene za slu\u0161alice, na dva zvu\u010dnika prakti\u010dki ne\u0107ete \u010duti 3D zvuk. Da biste u\u017eivali u detaljnom zvuku, slu\u0161alice razine SVEN AP860<\/b> ne\u0107e odgovarati, od jeftinijih slu\u0161alica trebate po\u010deti s Axelvox HD 241<\/b> \u2014 ve\u0107 \u0107e biti razlika u odnosu na SVEN AP860<\/b>, poput neba i zemlje. Tako to gledajte.<\/p>\n
