So using the latest builds works fine for you? Also, Sync GPU is only used with Metroid Prime 3 and Trilogy, it won't affect 1/2.

RCA is actually the name for a company. Radio corportation of america. A very large american company that was involved with pretty much anything to do with radio electronics back in the day. Since their equipment was so popular in the industry the cables they used quickly became the standard. The term "RCA" started being widely used to describe the most common connector used on their equipment. Since apparently everyone was too lazy to invent a proper term for it and just decided to name it after the company that invented it instead. Later on people began referring to any cable that uses this connector as an "RCA cable" since originally there was only one standard cable (now there are many, and we still haven't managed to start using terms to distinguish between them). Once consumers start using a specific term to refer to specific products companies are forced to sell and market the products using that name so people can easily identify them. Thus we're now stuck with everybody using this confusing and downright incorrect system of terminology. Subwoofer cables, rca audio cables, composite video cables, component video cables, spdif coaxial cables, and so on can all be referred to as "RCA cables". Stupid isn't it? kinkinkijkin Wrote:which would mean that he WOULD be switching from a digital to audio connection, Switching from a digital connection to an audio connection....

It wouldn't really surprise me if it were the DAC either, onboard audio solutions are all delicate and crappy, with very, very few exceptions I don't see how a DAC crashing an application would even be possible. kinkinkijkin Wrote:And, since I don't work with the micro/software side of audio, I didn't actually know that about HDMI. Though, he would be helped by a new soundcard if he also has S/PDIF optical inputs on his stereo receiver, since optical S/PDIF is superior to (if only more fragile than) coaxial S/PDIF. The thing is, though, optical cables cannot be bent too much or they will snap and become useless. Optical cables provide no improvement in audio quality assuming the same settings are used. And you don't need to work with the "micro/software side of audio" (whatever that means) to recognize that HDMI is a digital A/V connection and therefore doesn't involve your systems analog audio circuits. kinkinkijkin Wrote:Also, Creative still releases audio cards with hardware acceleration for some features of OpenAL, and only when it's through OpenAL. It's almost like they technically own the rights to OpenAL. Yeah, and they're useless. There are maybe a few games in existance that can make use of these features and none of them are demanding enough to actually get any speedup from it (they're all older games). They can only accelerate a limited number of functions in certain extensions to the API and only if they're used a specific way. These days everything these cards can do can be done just as fast in software (CPU based) without all of the restrictions put in place by hardware based solutions. Which is why devs have abandoned it. There is simply no point in hardware accelerated audio anymore. In fact it's often slower than software based solutions these days. It's not like 3D rendering where GPUs are dramatically faster at performing the task at hand than CPUs and we actually need that extra speed to do things that wouldn't otherwise be possible to do.

I meant to write analog, on that second one.
And the third one is product of forgetting what the conversation was about. Fourth, signal quality differs over distances of cable. Optical cables are far better for keeping high-quality signal than electrical cables, enough so that 20' optical cable can be the quality of 5' of electrical cable. The receiving end therefore has to do less guesswork (if it does any at all, if it doesn't then it just sounds worse), meaning that the original audio is better-maintained. Also, optical cables look cooler when the sleeving's taken off than electrical cables do.

You kind of need to make the cable a good 20m long before the electrical one will have noticeable signal degradation when it's a digital signal, though. There needs to be an awful amount of interference to make a 0 look like a 1.

@kinkin
None of that makes any sense. Digital audio transmission either works or it doesn't. There is no gradual loss of quality over long distances as with analog transmission. Once you reach a certain point it just stops working. Or in the rare case it "thinks" it's working and all you hear is extremely fucked up random static. And there is no "guesswork" involved other than parity. The max distance at which this happens in the case of spdif: -is so high that home users would never run into it -is mostly dependant on the quality of the cable, not the type -is generally higher with coaxial, not optical. The LEDs and thin plastic fiber used by optical spdif typically cut out after about 10-20 meters whereas good coax can go 30+. -generally can't be reached unless you chain multiple cables together without a repeater since pretty much all cables are capable of transmitting their full distance (obviously) Some audiophiles have suggested that optical produces inferior audio quality due to the additional clock jitter but there isn't much evidence to back this up. Pros of optical: -higher max bandwidth when using high quality cables which enables higher bitrate audio modes (OP is unlikely to make use of any of these assuming his receiver even supports them, it could be useful for someone trying to run uncompressed surround sound though) -can be used in environments with strong RF interference (unless you plan on having the cable near a big power transformer I don't see this being an issue) -no potential for ground loops (only an issue for stupid people) Pros of coax -higher max distance -no signaling issues with cables being crushed or bent -more flexible and durable cables -less clock jitter in some equipment Price is also mostly determined by the quality of the cable, not the type. Most people just use whichever one their equipment supports (usually optical) since most A/V equipment supports one or the other, not both. Edit: To clarify. This is because digital signals are virtually immune to RF interference and generally have built in error checking systems that reject corrupt data. The cables max length is based not on interference but rather at what point the power losses become so high that not enough electricity/light makes it through to the other end to register as a 1. This is the same to some degree with analog transmission but with analog the quality of the signal is also affected by distance since longer distances = more time to absorb interference.

lol, audio is just pulsed DC. There is no need to think about any HF issue

This thread should probably be moved to another section such as general discussion. I would move it but I'm not sure if it was left here for a reason or if other staff haven't bothered moving this thread.

Blue box != ticked. Just means it'll use the emulator default. Checked means it'll override and always enabled, unchecked means it'll override and always be off.
In most games, you're likely just seeing a placebo effect. (03-31-2014, 11:21 PM)Xtreme2damax Wrote: This thread should probably be moved to another section such as general discussion. I would move it but I'm not sure if it was left here for a reason or if other staff haven't bothered moving this thread. Revision 4.0-1341 got rid of the crackling I mentioned that the Xaudio and DirectSound backends were having. I also dropped a couple of ideas concerning the subject manner...and it seems that certain fellow Aspies went off on a tangent about audio cables...to which I must say that when you use a standard 3.5mm headphone jack, that is analog...Analog works wonders with Synchronous audio because the sine waves vary in carrier signal. When we try using synchronous audio on digital...it cuts off the signal at certain peaks of the sign wave...and it's hard to balance that. Asynchronous audio in most cases allowed for two or more simultaneous streams of the same data. A DAC, as people know, is the Digital to Analog Converter...Any video card still using VGA cables requires a DAC for a proper display because the video signal is digital but must be displayed on an analog monitor. Audio cards on PC's require a DAC circuit for people to use headphones. The benefit to this is that audio card manufacturers take advantage of this to get past the requirement that digital audio signals have time delays. Analog based audio devices have more tolerance for error than digital, but can be expensive to sheild it from (what little) interference the outside world provides. Metalergy is important but, if you use 24k gold plated cables...you are wasting your money because of the way audio equipment moves atoms in one direction...it has nothing to do with magnetism and everything to do with how malleable gold is. Silver is more common and less expensive and is standard for most digital equipment..and copper wire with proper impedance and wire gauge work just fine to deliver signals...I love optical for consistency, but it is so consistent it often sound brassy to me (my Aspie super power is in hearing electrical faults...and trust me...I do get distracted by it lol)... Digital bypasses all that crap and it sounds glorious in consistency... Ugh...before I get too ahead of myself...I hope a revision comes out adding 64bit DLL OpenAL file...it seems that the 32bit DLL still causes some issues with the DSP HLE ROM..

The only game that needs it according to a certain someone on this thread...is Metroid Prime 3...So far...all the games have it blue boxed to emulator default settings of having GPU Sync on...which means it is likely the emulator's core settings that has it on by default when it probably shouldn't. When I tick it, and I get mild crackles in audio (reduced in the revision, but still there)...I leave it blue boxed, the audio doesn't change tempo when there's a mild frame drop, when it's unticked at all (blank box), XAudio's speed stepping kicks in beautifully... Keep in mind that while I don't expect things I point out to be fixed immediately, I do notice things and I will point them out regardless if people already know or not ^_^. I don't mean any disrespect by it. |
