Audio: plans for supporting adpcm based samples ?

[OzzyOuzo]

From what i can read from the docs only 8bit samples are supported.

Zerosquare do you have plans for 4bit adpcm samples in the future ?

I'm not going to presume to speak for ZeroSquare, and please don't take this the wrong way...

 

In the past we have recieved multiple requests to add this or that feature, which we (sometimes) have then spent a lot of work on, only for the person requesting to go and produce absolutely nothing, ever.

 

The best way to get a feature implemented it to show us why you need it, in something tangiable.

[Zerosquare]

Implementing audio codecs with more efficient compression has been on the todo-list for a long time. 4-bit ADPCM is definitely possible (Orion_ did use it for Elansar), but what I'd really like to do is go beyond that, since DSP has some untapped number-crunching power. Unfortunately, it also has little local memory, which makes implementing more complex algorithms challenging. I have looked into designing an audio codec that's especially tailored for the Jaguar, but it's a big amount of work and it's still in the preliminary stages.

 

Also, the audio engine needs to be rewritten from scratch. As it is, it's both too rigid and too bare-bones.

 

TL;DR: Is something better planned? Yes. Will it be released any time soon? Unlikely.

 

And I fully concur with @CyranoJ's statement.

Well, adpcm implementation is not too complex it is just requiring a small table for delta values (less than 100 words) and compression / decompression code is tiny aswell.

Resulting in half sized samples for more sfx or better quality output.

 

This is not something i'm requesting though, it would be a very nice addition that's all.

 

Finally i'm working on a port of Captain Barrel for the Jaguar if it's tangiable enough for ya ^^

Nice to see a Jaguar port of a Neo Geo game you made, Ozzy. Maybe you can have Fragmare use Open MPT to convert the music to modules?

Hey there

 

I just joined the forum, and I thought that after giving my regards to my friend @CharlieCat my next visit would be to the fine fellas of the Jagstudio crew

I make games with OzzyOuzo as Neo Byte Force; this port of Captain Barrel is our first experience with the system, and we are both thrilled about it!

So I wanted to thank you guys for the work done on JS and the help & advice provided.

Hah! You did well - seems you have noticed we had a problem with prints, small and big 🤭

Sure, credit where credit is due, we'll be happy to add an in-game screen with the mention "powered by Jagstudio / Raptor API" and their logos if that is fine, as well as credit on the prints.

Just to be sure, these are the currently approved logos, right?

 

Thanks! 🍺

 

[+CyranoJ]

Welcome, thank you, and yes those are the logos

 

Look forward to the game.
