\"Cum<\/a><\/noindex>
\nProbabil c\u0103 aproape toat\u0103 lumea \u0219tie c\u0103 odat\u0103 cu lansarea Windows Vista \u00een 2007 \u0219i \u00een toate versiunile ulterioare, API-ul audio DirectSound3D a fost eliminat din Windows, iar \u00een loc de DirectSound \u0219i DirectSound3D au fost folosite API-uri noi, XAudio2 \u0219i X3DAudio. Din aceast\u0103 cauz\u0103, \u00een jocurile vechi au devenit inaccesibile efectele sonore EAX (efectele sonore ale mediului). \u00cen acest articol, voi explica cum s\u0103 readucem acel DirectSound3D\/EAX \u00een toate jocurile vechi care suport\u0103 aceste tehnologii, juc\u00e2nd pe Windows 7\/8\/10. Desigur, gamerii experimenta\u021bi \u0219tiu deja toate acestea, dar poate c\u0103 articolul va fi util pentru cineva. <\/p>\n

Jocurile vechi nu au disp\u0103rut \u00een negura istoriei; din contr\u0103, ele sunt foarte c\u0103utate, at\u00e2t de utilizatorii din genera\u021bia mai \u00een v\u00e2rst\u0103, c\u00e2t \u0219i de cei mai tineri. Jocurile vechi arat\u0103 mai bine pe monitoarele moderne cu rezolu\u021bie \u00eenalt\u0103, pentru multe jocuri apar moduri care \u00eembun\u0103t\u0103\u021besc texturile \u0219i shader-ele, dar \u00een privin\u021ba sunetului s-a \u00eent\u00e2mpinat o problema la \u00eenceput. Odat\u0103 cu lansarea genera\u021biei urm\u0103toare, Windows Vista, dup\u0103 Windows XP, dezvoltatorii Microsoft au considerat c\u0103 DirectSound3D era moral \u00eenvechit \u2014 avea o limitare la sunetul pe 6 canale, nu sus\u021binea compresia audio, era dependent de procesor \u0219i, prin urmare, a fost \u00eenlocuit de XAudio2\/X3DAudio. Deoarece tehnologia EAX de la Creative nu era un API de sine st\u0103t\u0103tor, precum era odat\u0103 A3D de la Aureal, ci doar o extensie a DirectSound3D, pl\u0103cile de sunet ale companiei Creative au r\u0103mas \u00een umbr\u0103. Dac\u0103 nu se folosesc wrapper-uri software speciale, atunci c\u00e2nd joci pe Windows 7\/8\/10 \u00een jocurile vechi, op\u021biunile de meniu care includ EAX vor fi inactive. Iar f\u0103r\u0103 EAX, sunetul din jocuri nu va mai fi at\u00e2t de bogat, amplu \u0219i pozi\u021bionat.
\n<\/a><\/noindex>
\nPentru a rezolva aceast\u0103 problem\u0103, compania Creative a dezvoltat un program-wrapper numit ALchemy, care redirec\u021bioneaz\u0103 apelurile DirectSound3D \u0219i EAX c\u0103tre API-ul OpenAL multiplatform\u0103. \u00cens\u0103 acest program func\u021bioneaz\u0103 oficial doar cu pl\u0103cile de sunet ale companiei Creative, \u0219i nu cu toate modelele. De exemplu, placa modern\u0103 Audigy Rx cu procesor DSP hardware CA10300 nu func\u021bioneaz\u0103 oficial. Pentru de\u021bin\u0103torii altor pl\u0103ci de sunet, cum ar fi Realtek \u00eencorporat, este necesar s\u0103 foloseasc\u0103 un alt driver software numit Creative Sound Blaster X-Fi MB, care este cu plat\u0103. Se poate \u00eencerca \u0219i programul native 3DSoundBack, dar acesta nu a fost finalizat de compania Realtek \u2014 s-a oprit la versiunea beta, func\u021bioneaz\u0103 slab \u0219i nu cu toate cipurile. \u00cens\u0103 exist\u0103 o metod\u0103 mai bun\u0103, care este mai u\u0219or de utilizat \u0219i gratuit\u0103. <\/p>\n

Prima metod\u0103<\/h2>\n

\nVoi \u00eencepe cu pl\u0103cile de sunet ale companiei ASUS. Pl\u0103cile de sunet ASUS DGX\/DSX\/DX\/D1\/Phoebus sunt bazate pe cipuri C-Media, iar cipurile ASUS AV66\/AV100\/AV200 sunt de fapt acelea\u0219i cipuri C-Media, dar remarcate. \u00cen specifica\u021biile acestor pl\u0103ci de sunet este men\u021bionat c\u0103 suport\u0103 EAX 1\/2\/5. Toate aceste cipuri au mo\u0219tenit de la predecesorul lor CMI8738 blocul DSP hardware-software EAX 1\/2, EAX 5 fiind deja software.<\/p>\n

De\u021bin\u0103torii pl\u0103cilor din seria Xonar au avut mult noroc, toat\u0103 lumea a v\u0103zut butonul GX pe panoul driverului, dar poate nu to\u021bi \u0219tiu ce face acesta. Voi ar\u0103ta \u00een capturi de ecran din programul AIDA64, a\u0219a arat\u0103 tab-ul DirectX-sound c\u00e2nd butonul este inactiv \u0219i la de\u021bin\u0103torii pl\u0103cilor de sunet \u00eencorporate Realtek \u00een Windows 7\/8\/10:<\/p>\n

\"Cum
\nToate buffer-ele de sunet sunt egale cu zero, toate API-urile sunt inactive. Dar imediat ce activ\u0103m butonul GX, vedem<\/p>\n

\"Cum
\nAdic\u0103, este foarte convenabil \u2014 nu este nevoie s\u0103 rula\u021bi programe suplimentare, cum ar fi Creative ALchemy, \u0219i s\u0103 copia\u021bi fi\u0219ierul dsound.dll \u00een fiecare folder cu jocul. Aici apare o \u00eentrebare mare: de ce nu a f\u0103cut asta compania Creative \u00een driver-ele sale? Mai mult, \u00een toate noile modele Sound Blaster Z\/Zx\/AE nu folose\u0219te procesorul DSP pentru procesarea EAX, ci o face software prin driver cu algoritmi simplifica\u021bi. Unele persoane cred c\u0103 procesarea software a sunetului este suficient\u0103, deoarece procesoarele moderne sunt mult mai puternice dec\u00e2t procesoarele sound card-urilor de acum 10 ani, care procesau sunetul hardware. Acest lucru nu este adev\u0103rat. CPU-ul este optimizat pentru a procesa comenzi x86, iar DSP proceseaz\u0103 sunetul mult mai repede dec\u00e2t CPU-ul, la fel cum placa grafic\u0103 efectueaz\u0103 rasterizarea mai repede dec\u00e2t CPU-ul. CPU-ul este suficient pentru algoritmi nu foarte complec\u0219i, dar o reverbera\u021bie de calitate, cu multe surse de sunet, va utiliza prea multe resurse chiar \u0219i de la un CPU puternic, ceea ce va afecta FPS-ul \u00een jocuri. Acest lucru a fost deja recunoscut de compania Microsoft \u0219i au revenit la suportul pentru procesarea sunetului cu procesoare DSP \u00een Windows 8, iar compania Sony a ad\u0103ugat \u00een consola sa PS5 un cip dedicat pentru procesarea sunetului 3D.<\/p>\n

A doua metod\u0103<\/h2>\n

\nAceast\u0103 variant\u0103 este potrivit\u0103 pentru utilizatorii pl\u0103cii de sunet integrate \u00een pl\u0103cile de baz\u0103, care sunt majoritatea. Exist\u0103 un astfel de proiect DSOAL<\/a><\/noindex> \u2014 este o emula\u021bie software a DirectSound3D \u0219i EAX cu ajutorul OpenAL (OpenAL trebuie s\u0103 fie instalat obligatoriu \u00een sistem) care nu necesit\u0103 accelerare hardware. Dac\u0103 cipul dvs. de sunet are vreo func\u021bie hardware pentru procesarea sunetului, aceasta va fi folosit\u0103 automat. Programul func\u021bioneaz\u0103 at\u00e2t de bine, \u00eenc\u00e2t prin el EAX a func\u021bionat la mine \u00een toate jocurile vechi, unde exist\u0103 op\u021biunea EAX \u00een set\u0103ri. A\u0219a arat\u0103 fereastra AIDA64, dac\u0103 copia\u021bi fi\u0219ierele DSOAL \u00een folderul programului:<\/p>\n

\"Cum<\/p>\n

Dac\u0103 acest lucru nu s-a \u00eent\u00e2mplat \u0219i ave\u021bi o imagine, ca \u00een prima captur\u0103 de ecran, atunci driver-ul nativ Windows dsound.dll <\/b>nu permite interceptarea API-ului, a\u0219a cum a fost \u0219i \u00een cazul meu. Atunci o astfel de metod\u0103 va ajuta \u2014 va trebui s\u0103 porni\u021bi de pe un CD Windows Live \u0219i s\u0103 \u0219terge\u021bi fi\u0219ierul dsound.dll<\/b> cu ajutorul utilitarului Unlocker (mai \u00eent\u00e2i s\u0103 face\u021bi o copie \u00een caz de revenire) din directorul C:WindowsSysWOW64<\/b> \u0219i s\u0103 scrie\u021bi \u00een locul acestuia acele dsoal-aldrv.dll<\/b> \u0219i dsound.dll<\/b>. Am f\u0103cut a\u0219a \u0219i at\u00e2t Windows, c\u00e2t \u0219i toate jocurile au func\u021bionat f\u0103r\u0103 probleme, ba chiar este mai convenabil \u2014 nu trebuie s\u0103 copiez de fiecare dat\u0103 aceste fi\u0219iere \u00een folderele jocurilor, iar \u00een ultim\u0103 instan\u021b\u0103, le pot returna pe cele originale dsound.dll<\/b> la loc. Adev\u0103rul este c\u0103 aceast\u0103 metod\u0103 se potrive\u0219te, dac\u0103 nu folose\u0219ti alte pl\u0103ci de sunet ASUS sau Creative, pentru c\u0103 \u00een acest caz, DirectSound3D va func\u021biona \u00eentotdeauna doar prin DSOAL, nu prin driverul original sau ALchemy.<\/p>\n

\u2192 Descarc\u0103 biblioteca complet\u0103 a celei mai recente versiuni este disponibil\u0103 aici<\/a><\/noindex><\/p>\n

Compar\u00e2nd cum sun\u0103 EAX pe diferite pl\u0103ci de sunet, am descoperit cu surprindere c\u0103 pe Realtek-ul integrat EAX sun\u0103 mai bine dec\u00e2t pe Asus sau pe Audigy Rx. Dac\u0103 citim fi\u0219ele tehnice, aproape toate cipurile Realtek suport\u0103 DirectSound3D\/EAX 1&2. Rul\u00e2nd AIDA64 pe Windows XP, po\u021bi vedea:<\/p>\n

\"Cum
\nSe pare c\u0103 Realtekii, spre deosebire de pl\u0103cile de sunet ASUS \u0219i Creative, suport\u0103 \u0219i un alt tip de I3DL2 (nu \u00een fiecare fi\u0219\u0103 tehnic\u0103 Realtek este men\u021bionat acest lucru). I3DL2 (Interactive 3D Audio Level 2) \u2014 este un standard industrial deschis pentru lucrul cu sunetul interactiv 3D, o extensie pentru DirectSound3D pentru lucrul cu reverbera\u021bia \u0219i occluzia. \u00cen principiu, este analog cu EAX, dar sun\u0103 mai pl\u0103cut \u2014 reverbera\u021bia pasilor \u00een jocuri este mai pl\u0103cut\u0103 atunci c\u00e2nd personajul fuge printr-o pe\u0219ter\u0103 sau un castel, sunetul tridimensional \u00een camere este mai realist. A\u0219adar, dac\u0103 un joc vechi func\u021bioneaz\u0103 pe Windows XP, eu joc doar pe XP, \u00een caz c\u0103 motorul de sunet poate utiliza I3DL2. De\u0219i DSOAL este un proiect deschis \u0219i oricine \u00eel poate \u00eembun\u0103t\u0103\u021bi, el nu va putea niciodat\u0103 s\u0103 acceseze I3DL2, deoarece OpenAL nu func\u021bioneaz\u0103 cu I3DL2, ci doar cu EAX 1-5. Dar exist\u0103 \u0219i o veste bun\u0103 \u2014 \u00eencep\u00e2nd cu Windows 8, I3DL2 este inclus \u00een biblioteca XAudio 2.7.<\/a><\/noindex>A\u0219adar, sunetul \u00een jocurile noi pe Windows 10 va fi mai bun dec\u00e2t pe Windows 7.<\/p>\n

\u0218i, \u00een cele din urm\u0103, vreau s\u0103-\u021bi amintesc c\u0103 toate aceste tehnologii de sunet 3D au fost dezvoltate pentru c\u0103\u0219ti, pe dou\u0103 difuzoare aproape c\u0103 nu vei auzi sunet 3D. Pentru a te bucura de un sunet detaliat, c\u0103\u0219tile de nivel SVEN AP860<\/b> nu sunt potrivite, din c\u0103\u0219tile ieftine ar trebui s\u0103 \u00eencepi cu Axelvox HD 241<\/b> \u2014 deja va fi o diferen\u021b\u0103 fa\u021b\u0103 de SVEN AP860<\/b>, ca cerul \u0219i p\u0103m\u00e2ntul. Asta este, orienteaz\u0103-te cam a\u0219a.<\/p>\n
