results of P.E.O.PS spu2 plugin

[jareg]

Nice Plugin in the bios the sound was music to my ears ofcourse it had some flikkers but at least its sound

[refraction]

nice to finally hear sound guys!!! this is the problems i can distinguish with it.

1. Sound doesnt seem to be flushing the buffer, just playing the same bit looped over n over rather than getting the next data.

2. Only 1 channel plays at a time in each speaker (1 in left and 1 in right) that i can hear.

oh and another thing, was looking at the source, and it was saying sound format 44100, i thought the PS2 was 48khz ADPCM?

The SPU2 has a looping sound buffer. This is the cause of the first error. Chances are this will be fixed, remember this is a far from complete beta. Secondly I believe the sweeping between speakers is due to some effects PEoPs is attempting to mix. And thirdly it does play at 48KHz, so that is an error.

ehehe, sure... the more stuff is running in pcsx2, the better the plugin can get... currently I've done most of the spu emulation "blindly" (or better "deaf" ), based simply on guessings of other people

hard to say... the few sounds I have heard were mixed fine, though.

ah, no, there is some misunderstanding here... sure, the real PS2 is having a 48 KHz output, but that doesn't mean that all the voices are running at 48 KHz all the time (as a matter of fact the voices run at all kind of different frequencies). They will just get up/downsampled to 48 KHz from the real PS2.

On PCs it doesn't make much sense to use this output frenquency (since not all sound cards can do it), so it's a better way do up/downsample the voices to something _all_ nowadays cards can handle... and that's what the P.E.Op.S. plugin is doing...

well pete, your the man! you know your stuff my hat is off to you lol. im more than sure you can fix all the problems in next to no time, if you can do this much blind coding!

you have an old version of GSMax. The new versions of PCSX2 had some internal changes that made it incompatible. Sorry there is nothing that can be done about this.

[Songoo]

So where can i download newer version of GSMax?
I downloaded all from http://www.pcsx2.net/downloads.php .

Okay dude, um your totally off topic.

Anyways I just tried the plugin running the SCPH NTSC BIOS 10000 Jap and holy cow I was scared as hell. The sounds were great but sounded like a scray movie. Is there any way I can record the sound to show you guys? God I almost peed my pants. I wanna show you all how it sounded. But I need to know how I can record sound :/

i think theres an option in the spu plugin config (mentioned in the release info) about writing a wave file to disk while running the emu, give it a shot.

[Razor Blade]

Cool. Thanks. Okay heres recorded sound from the Bios. It starts off neat and then almost turns into a funky techno. LOL. Download it and check it out.

Not really scary movie IMO, but still intresting uhh.. product a bit quiet tho but i guess it is good result from ps2 sound plugin =P

Good to know, thanks for the information. I just knew that the core SPU2 frequency is 48000 Hz or 48 KHz.

The new version is in development. don't ask when it'll come out. just be surprised and happy when it does.

First congrats to Pete, excellent plugin, great progress so far.



Now to clear up all this confusion over the sources and other stupid posts as Elly mentioned Pete saw our sources yes because I sent him and email asking for his help, since he has done work in Spu emulations and the ps2sp team started out knowing very little about Spu2 emulation but anyway below is the email he sent to me giving helpful advice that the whole team is greatful of As for ps2sp and peops spu2 I don't see any reason why we all can't work together to help each plugin progress further.


Email attached.

Hi Kanodin,

I had some time this weekend, so I looked at your spu2 plugin. Well, it's a VS.net project, so I couldn't compile it (I still use the VS6.0 here, for various reasons), but I read through the sources, to see how far you have got.

Well, no offense, but I think you have currently around 5% of the real PS2 spu emulated... it's some kind of luck that you can hear some sounds occasionally

Most likely you know it already, but basically you have to do the following to progress further:

1. remove the current fmod sound buffer filling from the writeDMA7Mem func... that's simply an hack

2. create a sound thread or sound timer func or a sound func triggered by spu2async, where you can do all the Vag-decoding on the fly, meaning: look for each of the 48 channels, if it should play (key on register)... if yes, decode some of its data, and feed it to your fmod sound system.

3. if you have the #2 basics, you can start with adding more and more real PS2 spu register emulation funcs... volume and pitch first, adsr and reverb prolly last... the more registers you have emulated, the better the compatibility will get (since games can and will read certain register values to work properly).

So I think you have still a lot of work to do

Maybe I will do a Peops open source spu->spu2 port, to give you a more complete open source plugin you can work with.

Cu
Pete




Again thank you Pete for your help in spu2 emulation heh besides a little competition is always fun

sound familier?

I kinda expected to see one released shortly after receiving the email, I'm glad Pete has released a spu2 port it helps us all out with the spu2 programming.

Oh, the P.E.Op.S. spu2 version 1.0 has still a lotta bugs (especially in the spu address decoding), so I hope you will not use too much infos from it... better wait for version 1.1, I will release it soon (this week, I think... I just have to find a way how to run the same plugin in PCSX2 0.6 (spu2 interface version 2) and the next PCSX2 (spu2 interface version 3).... mmm... maybe I will just release two different binaries, we will see.

[chesso]

good to hear...

Hmmm, interesting I suppose so but still I have to admit it is great none the less :P hopefully we can both have fully working spu2's in the near future.
