Please fix bad audio emulation

[Riptor]

MS3 and MSX have both very bad audio emulation. Please fix this!

I honestly don't know what you mean unless your PC can't handle the game for some reason or it's playing just under a playable frame rate causing audio skipping/stuttering. This is a direct emulation port of the arcade game with online multiplayer, achievements and better controller support as well as 16:9 aspect ratio. I highly doubt they purposely put in lower quality audio into a game that's only a few hundred megabyte cartridge. The game even has the same amount of slowdown as the arcade version because it's an arcade port with software emulating Neo-Geo's arcade hardware.

It would be better if you explained it further or posted a video of the issue to help show it off as well as what audio drivers you have and what your sound card is running at under your prefered device's Advanced Speaker Properties.

The issue he speaks of is well-documented; the audio (most noticeably the music) sometimes plays a bit faster/slower than usual for short intervals. This does not occur on the Neogeo release of MSX. It is not an issue with his hardware, it happens to nearly everyone as far as I can tell. However, it's not very noticeable and people who aren't looking out for it may miss it entirely.

The framerate probably jumps too high or too low and causes the music to play too fast, or so would be my guess with emulation and is it only MSX? Because I know I haven't heard it on MS3 at all, not on Steam or on my Android. I'd notice it, I mean the music slows down when the game does during intense scenes but so far nothing too bad, nothing to make it unplayable or anything like that for me at least.

If you want to be real picky you can hear a big diffrence in the GO sound and continue count down vs other emulated versions of both Metal Slug games.

I'll have to give it a try then because out of the handful of times I played it on Android and PC I didn't notice it besides like I said, the slowdowns or speedups.

A lot of the sounds are wrong. Mostly the high pitched laser-esque sounds

Those among other sounds, I noticed a lot of sounds are too scratchy and also higher pitched than they should be. Can't believe I totally missed that. Specially since I used to own the MS MVS cabinet. I also noticed the music is usually slower than it should be, not just occasionally, it's like, always slower than normal. Guess I didn't notice it because the first few times I played the PC version I had my sound system off and the only time I did play with sound on was with family so I wasn't really paying attention to the noises but wow, yeah, there's something up, I'd say it's either emulating the sound wrong (duh, obviously.) OR (and I'm not sure exactly how the Neo Geo handled sound.) but maybe the sound device it's emulating is emulating too slow or too fast? Or it seems like it's using the wrong tones plus a mix of the two. I tried changing my sampling rates and nothing changed either so it's not a sample rate compatibility problem and since it's so wide spread I'd doubt it would be linked to a specific set of hardware compatibility unless it dislikes Realtek audio devices which most PC's have.

The fanfare music is particularly bad.. Them drums.

I think the real issue is the frame timing of the emulation.

People with sharp eyes will notice that the game itself speeds up and slows down regularly in bursts (just a little bit), which creates the impression of slightly stuttering framerate because the 30 in-game frames are not being displayed at regular intervals.

I would assume that the sound emulation core is tied to the overall emulation core, which would cause the music to speed up/down during these "stuttering periods".

So, in order to fix the sound, DotEmu needs to fix the uneven frame pacing their NeoGeo emulator has. But this has been going on since the first day of their Metal Slug 3 Steam release and I do not expect a fix, neither soon nor ever.

If I am wrong (and please, DotEmu, make me wrong) I would REALLY like to see the fix applied to not only MSX, but also MS3 (or any other Metal Slug releases they may have at the time, as well as any future releases).

Yeah, that's it for me. I remember the good ol' days with one of the best soundtracks i have ever heard – now reduced into some glitchy distortion. I buyed the bundle (MS, MSX and MS3) to have a nice Metal Slug comeback. But damn, with all this glitches is really unplayable.

that's really sad they still didn't fix this. I noticed all the ports have a 1cc achievement which is cool, but to mess up the sound emulation is criminal.
