\nDet er nok n\u00e6sten alle bekendt med, at med udgivelsen af Windows Vista tilbage i 2007, efterfulgt af alle de kommende versioner af Windows, blev lyd-API'et DirectSound3D fjernet fra Windows. I stedet for DirectSound og DirectSound3D begyndte man at bruge de nye API'er XAudio2 og X3DAudio. Som f\u00f8lge heraf blev de lydm\u00e6ssige specialeffekter EAX (lydeffekter til omgivelserne) utilg\u00e6ngelige i gamle spil. I denne artikel vil jeg fort\u00e6lle, hvordan man kan f\u00e5 det gamle DirectSound3D \/ EAX tilbage i alle gamle spil, der underst\u00f8tter disse teknologier, mens man spiller p\u00e5 Windows 7 \/ 8 \/ 10. Selvf\u00f8lgelig ved erfarne gamere alt dette, men m\u00e5ske vil artiklen v\u00e6re nyttig for nogle. <\/p>\n

Gamle spil er ikke blevet begravet i historiens affald, tv\u00e6rtimod er de i h\u00f8j kurs b\u00e5de hos den \u00e6ldre generation samt de yngre. Gamle spil pr\u00e6senterer sig bedre p\u00e5 moderne sk\u00e6rme med h\u00f8j opl\u00f8sning, og der kommer mods til mange spil, der forbedrer teksturer og shaders, men hvad ang\u00e5r lyden har det fra starten v\u00e6ret en udfordring. Med udgivelsen af den n\u00e6ste generation Windows Vista, efter Windows XP, mente Microsoft-udviklerne, at DirectSound3D var moralsk for\u00e6ldet \u2014 det havde en begr\u00e6nsning p\u00e5 6-kanals lyd, underst\u00f8ttede ikke komprimering af lyd og var processorafh\u00e6ngigt, derfor blev det afl\u00f8st af XAudio2 \/ X3DAudio. Da EAX-teknologien fra Creative ikke var et selvst\u00e6ndigt API, som A3D fra Aureal engang var, men blot en udvidelse af DirectSound3D, blev Creative's lydkort sat p\u00e5 sidelinjen. Hvis man ikke bruger specielle software-wrappers, vil menuvalgene, der inkluderer EAX, v\u00e6re deaktiverede, n\u00e5r man spiller p\u00e5 Windows 7 \/ 8 \/ 10 i gamle spil. Uden EAX vil lyden i spillene ikke v\u00e6re s\u00e5 fyldig, detaljeret og positioneret.
\n<\/a><\/noindex>
\nFor this problem, Creative has developed the ALchemy wrapper program, which redirects DirectSound3D and EAX calls to the cross-platform OpenAL API. However, this program officially works only with Creative's sound cards, and not all models. For instance, the modern Audigy Rx card with the hardware DSP processor CA10300 does not officially support it. Owners of other sound cards, such as integrated Realtek, need to use the Creative Sound Blaster X-Fi MB software driver, which costs money. You can also try the native 3DSoundBack program, but it was never completed by Realtek \u2014 it got stuck in beta and works inconsistently with some chips. But there is a better way; it\u2019s easier to use and free. <\/p>\n

Den f\u00f8rste metode<\/h2>\n

\nLet\u2019s start with ASUS sound cards. ASUS sound cards DGX\/DSX\/DX\/D1\/Phoebus are based on C-Media chips, and even ASUS AV66\/AV100\/AV200 chips are just rebranded C-Media chips. The specifications of these sound cards mention that they support EAX 1\/2\/5. All these chips inherited the software-hardware EAX 1\/2 from their predecessor CMI8738, while EAX 5 is already software-based.<\/p>\n

Xonar card owners are quite fortunate; everyone has seen the GX button on the driver panel, but not everyone knows what it does. I will show it using screenshots from AIDA64; this is how the DirectX sound tab looks when the GX button is inactive, especially for owners of integrated Realtek sound cards in Windows 7\/8\/10:<\/p>\n

\"S\u00e5dan
\nAll sound buffers are equal to zero, and all APIs are inactive. But as soon as we turn on the GX button, we see<\/p>\n

\"S\u00e5dan
\nDet er meget praktisk - man skal ikke starte ekstra programmer som Creative ALchemy og kopiere dsound.dll-filen til hver spilmappe. Dette rejser et stort sp\u00f8rgsm\u00e5l: Hvorfor gjorde Creative ikke dette i deres drivere? Desuden bruger de i alle nye modeller af Sound Blaster Z\/Zx\/AE ikke en hardware DSP-procesor til EAX-behandling, men g\u00f8r det programmatisk gennem driveren ved hj\u00e6lp af forenklede algoritmer. Nogle mennesker mener, at softwarelydbehandling er tilstr\u00e6kkelig, fordi moderne CPU'er er meget kraftigere end de lydkortprocessorer, der var for 10 \u00e5r siden, som behandlede lyd hardwarebaseret. Det er helt forkert. CPU'en er optimeret til at behandle x86-kommandoer, mens DSP'en behandler lyd meget hurtigere end centralprocessoren, ligesom grafikkortet rasteriserer hurtigere end CPU'en. CPU'en er tilstr\u00e6kkelig til enkle algoritmer, men kvalitetsreverberation med mange lydkilder vil tage for mange ressourcer, selv fra en kraftig CPU, hvilket vil p\u00e5virke FPS i spil. Dette er allerede anerkendt af Microsoft, som har genintroduceret DSP-lydbehandling i Windows 8, og Sony har ogs\u00e5 tilf\u00f8jet en separat chip til 3D-lydbehandling i deres PS5-konsol.<\/p>\n

Den anden metode<\/h2>\n

\nDenne mulighed er velegnet til brugere med et integreret lydkort p\u00e5 moderkortet, som der er mange af. Der findes et projekt DSOAL<\/a><\/noindex> er en softwareemulering af DirectSound3D og EAX med OpenAL (OpenAL skal v\u00e6re installeret p\u00e5 systemet) som ikke kr\u00e6ver hardwareacceleration. Hvis din lydchip har nogle hardwarefunktioner til lydbehandling, vil de blive brugt automatisk. Programmet fungerer s\u00e5 godt, at EAX har fungeret for mig i alle gamle spil, hvor der er en EAX-mulighed i indstillingerne. S\u00e5dan ser AIDA64-vinduet ud, hvis man kopierer DSOAL-filerne ind i programmappen:<\/p>\n

\"S\u00e5dan<\/p>\n

Hvis det ikke er sket, og du har et billede som p\u00e5 det allerf\u00f8rste screenshot, s\u00e5 betyder det, at Windows dsound.dll <\/b>forhindrer API-tilfangetagning, ligesom det var tilf\u00e6ldet for mig. S\u00e5 kan f\u00f8lgende metode hj\u00e6lpe - du skal starte fra en Windows Live-CD og slette filen dsound.dll<\/b> med hj\u00e6lp fra v\u00e6rkt\u00f8jet Unlocker (forinden lave en kopi i tilf\u00e6lde af, at du skal rulle tilbage) fra mappen C:WindowsSysWOW64<\/b> og erstatte den med dsoal-aldrv.dll<\/b> og dsound.dll<\/b>Jeg gjorde det samme, og b\u00e5de Windows og alle spil fungerede fejlfrit, og det er endda lettere \u2014 man skal ikke hver gang kopiere disse filer ind i spillenes mapper, i n\u00f8dstilf\u00e6lde kan man altid f\u00e5 de originale tilbage. dsound.dll<\/b> Denne metode passer dog kun, hvis du ikke vil bruge andre ASUS eller Creative lydkort, for i s\u00e5 fald vil DirectSound3D altid kun fungere gennem DSOAL, og ikke gennem den originale driver eller ALchemy.<\/p>\n

Du kan lytte til DSOAL i denne video:<\/p>\n

Da jeg sammenlignede hvordan EAX lyder p\u00e5 forskellige lydkort, opdagede jeg overraskende, at EAX lyder bedre p\u00e5 det indbyggede Realtek end p\u00e5 Asus eller p\u00e5 min Audigy Rx. Hvis man l\u00e6ser databladene, s\u00e5 st\u00f8tter n\u00e6sten alle Realtek chips DirectSound3D\/EAX 1&2. Ved at k\u00f8re AIDA64 fra Windows XP kan man se:<\/p>\n

\"S\u00e5dan
\nDet viser sig, at Realtek, i mods\u00e6tning til ASUS og Creative lydkort, ogs\u00e5 underst\u00f8tter et eller andet I3DL2 (det st\u00e5r ikke i hverken Realtek datablad). I3DL2 (Interactive 3D Audio Level 2) er en \u00e5ben industristandard for arbejde med 3D interaktiv lyd, en udvidelse til DirectSound3D for h\u00e5ndtering af rumklang og okklusion. Det er i princippet et alternativ til EAX, men lyder mere behageligt \u2014 mere behagelig rumklang i spil n\u00e5r karakteren l\u00f8ber i en hule eller slot, mere realistisk rumklang af surround lyd i rum. S\u00e5 hvis et gammelt spil k\u00f8rer p\u00e5 Windows XP, s\u00e5 spiller jeg kun p\u00e5 XP, i tilf\u00e6lde af at lydmotoren kan tr\u00e6kke p\u00e5 I3DL2. DSOAL, selvom det er et open source projekt og enhver kan forbedre, vil aldrig kunne bruge I3DL2, da OpenAL ikke arbejder med I3DL2, kun med EAX 1-5. Men der er ogs\u00e5 gode nyheder \u2014 fra og med Windows 8 er I3DL2 inkluderet i biblioteket XAudio 2.7<\/a><\/noindex>. S\u00e5 lyden i nye spil under Windows 10 vil v\u00e6re bedre end under Windows 7.<\/p>\n

Og til sidst vil jeg minde om, at alle disse 3D-lyd teknologier blev udviklet til hovedtelefoner, du vil n\u00e6sten ikke h\u00f8re 3D-lyd p\u00e5 to h\u00f8jttalere. For at nyde detaljeret lyd skal hovedtelefoner af niveauet SVEN AP860<\/b> ikke v\u00e6re tilstr\u00e6kkelige; blandt de prisvenlige hovedtelefoner b\u00f8r man starte med Axelvox HD 241<\/b> \u2014 der vil allerede v\u00e6re en forskel i SVEN AP860<\/b>, som nat og dag. S\u00e5dan kan du orientere dig.<\/p>\n
