SVN Sound Core Replacement

Deathlike2 · Post by **Deathlike2** » Wed Jan 31, 2007 10:12 pm

Heavy work is being done on the sound core at the moment. Please do not report any bugs from SVN until we say it is safe to do so.

The last working revision is 4538.

We will smack you silly if you complain.

Sweet deal!

what is the significance of saying r4538 is the last working revision? do you want bug reports for that revision but not bug reports for special chip games?

People will be asking for a point of reference for when ZSNES was working last. I don't see an issue mentioning that if you thought about it longer.

SVN bug reports should only be limited to non-emulation related stuff. At the moment, we just don't want bug reports at all regarding what is in SVN now because of what is being done.

thanks for clearing that up.

Is SVN being used to present the new sound core replacement? Because I was pretty sure pagefault didn't like using SVN for this.

I think maybe pagefault has finished private development on the sound core and is now merging it with the trunk, for bug testing, etc.

We are using blargg's DSP paired with a souped up version of _Demo_'s SPC.

We made some progress, note we still have some things to work out, so the final version will sound better than this recording, right now we're dropping the occasional sample.

That's for Chrono Trigger fans. A lot of the Lavos sounds which never played right now do. So Square annoyances are almost gone

Note I cut out some silent areas from that file, and there may also be a bit of quality loss from the compression. However if you were familiar with the Lavos sound before, you'll hear how much this is improved.

WOW. That sounds great.

That sounds incredible. I can't wait to test the core myself.

I really need to get some new cables for my SNES so I can hear the original audio again. The new sound core is MUCH better. I can't help but think the lead-up sound effects at the beginning aren't quite right though.

It's unfortunate that we have to keep implementing our own cores into our projects rather than combining them. anomie's core works just fine as well, and if we were to utilize the same core, we could fix bugs in all emulators at the same time.

Ah well, sadly anomie hasn't had much free time lately, anyway. I should check with blargg to see how knowledgable he is with the S-DSP. I have some questions regarding ESA/EDL, and with anomie MIA, it seems we don't really have any experts left who can perform hardware tests :(

Good job on the new core, though. It sounds great so far. Hopefully this will fix the longstanding freezing issue with Der Langrisser. It would be a shame to advise users not to use ZSNES when we finally do release that translation patch.

I told you I cut out some mostly silent parts, compressed it, and still some samples are missing here and there, keep that in mind.

Wow, this new core sounds great. Keep up the good work.

Status update: pagefault is working on the Windows/DOS side of the audio. SDL port should be fine for the most part, but you MUST use libao (it looks like it will be mandatory anyways).

To use libao, make sure to pass in --enable-libao to autogen.sh or configure.

Known issues: There's a ton of them, and they will be dealt with. These issues included savestates, movies, SPC/audio dumping, stuff used by the old DSP core, and other stuff that may not have been mentioned here (this is an important change after all). Also, you will have audio playback issues if you don't hit 50/60fps (a buffer will be implemented to handle that).

The Sound Menu is completely useless at the moment. There are no audio filters to speak of, however we will integrate the portions of the new DSP (whatever it has.. featurewise, just like the latest NTSC filter).

As a reminder, no complaints until we say it is done.

404 error

I also noticed that your whole site is gone (seems that your host is moving to a new server): do you have a temporary mirror for the mp3 until the problem is solved?

Jipcy · Post by **Jipcy** » Thu Feb 08, 2007 5:48 pm

If there was a problem, it seems to be fixed now. I can access the site and download the mp3 no problem here.

Yes, the link to the mp3 is working again (the new sound seems awesome compared to the old one), while the main page is no more (there's only an image saying ex1.edgeemu.com).

Something is wrong with you/your network/your computer, because I have no problems accessing the main site. Are you going to "http://nsrt.edgeemu.com"?

well just my luck... my tv has been busted for 2 months and i just got it fixed today. one of the first things i did was startup zget to get the latest build only to find out the sound doesn't work at all. so i came here and found this.

is there any way to have zget make build that still has sound? if not where can i get a athlon xp optimized version of the last build that did work?

is there an eta on sound implamentation?

thanks

edit: got the newest zget i see how now.

When it asks Update to a particular revision? (y/N), hit y, then enter 4538.

Yes, and it works now...
I use firefox as default browser: I "fooled" the site changing the browser ID to internet explorer (with the "user agent switcher" extension), then I switched back to the usual ID, and now it permanently works, this thing is very weird

According to pf, we will have sound in the Windows port as soon as he finishes writing the Vista driver. Vista uses a different audio system, and although I suspect the sound code would be "ok" with Vista (DSound in Vista uses a wrapper to the Wave output), pagefault wants the sound code be native to Vista, so it can use Vista's sound controls as well.

Post by **Nach** » Thu Feb 22, 2007 8:20 am

And despite having sound in any given port, we're still not done yet with updating the SPC, or tying in any of our considerable list of sound options, or SPC related features. So no complaining until we say we're done.
