So you might want to do some reading about achieving this without many speakers. That's what Head Related Transfer Function research is about. (HRTF). WHY do you hear sounds coming in three dimensions, and how to replicate that. That's possible with many fewer loudspeakers.
Next, the latest theater sound systems are designed around the idea of sound "objects" that are then mapped onto 2 or more speakers. Dolby Atmos and Datasat's Auro are like this. So, you may find much about recording and playing back in 3D this way.
As I understand it, and I understand it very little... the idea is that instead of a set of recordings mapped to a track, and then mixed to speakers, you create a sound object, like a space ship, and decide where in 3D space it should be. This let's the composer think in terms of space instead of tracks.
The idea comes I think from games, and virtual sound fields.

Yes. it's the idea of sound object.I do not know how to explain it yet, because i still do not know exactly what I would do, but the idea of the composer who thinks in terms of space attracts me a lot.
And yes, i was just thinking of reducing the number of speaker's, and maybe do a 5.1 system without the sub. Maybe a sort of 5 full range active speakers.
I'm searching for a low budget/decent speakers. If you've got some hints, don't hesitate!

Well, the playback is different than the composition. :)
I make all my own speakers, but I have to rely on off the shelf decoders either built into my BluRay players or receivers, etc.
If you want a reference grade 2-way speaker system, my free kit plans are available online, but at around $350/pair may be a lot if you want to put 24 speakers or something. :)
So, just for understand, I would need, in addition to the speakers and the software that makes me the encode, also a receiver that do the decode, right?
So, it will be a little expensive thing. But i think i'll do.
And yes, your speakers price is too much for me, at the moment, sorry :/ Maybe in the future, when i will understand and will have done a little of experience.
Yes. I mean, you are basically doing home theater. :)
So it's not just a matter of the speakers, but the decoder, power, etc.
Using a pure PC setup however.... you could do multitrack with multi-track outputs. You'll still need 1 amp per speaker, but you could do the multi-tracking and output all on the PC.
For that, you'll need to research professional PC mastering software. Of course, there's versions for Mac and PC.

Yes yes. I've got the software. This is the only thing that i have. It's an extension for MaxMsp: http://spatium.ruipenha.pt/
But regarding the hardware, I've nothing.
The last thing I want to ask is: if I take a receiver, I would not need an audio interface, is it true? The receiver will make the audio interface/mixer function?
If you are using a desktop PC, they have 7.1 outputs in the form of a cluster of mini-jacks.
If you want more than that, you'll need a professional PC multi-channel interface. Some are USB, while some are PCI/ISA interface based.
That's if you don't need to create a DVD or multi-channel DSD presentation.
If you want to send your creations out as DVD audio or the like, then listeners would need a consumer HT decoder or something like that. Music-in-the-Round has a lot more on that.
Best,
Erik
