I've researched surround sound but run into dead ends. Every time.

I am a composer/musician and I want to get the live sound of many instruments playing in one crowded room instead of the many dubs of many empty rooms usual shit sound.

My end goal is to play individual audio files on individual speakers, but have them all synchronized. I can do 2 at a time with stereo. Surround sound systems can get me to 6 or 8 (5+1 or 7+1). I'm looking for at least 12 channels. How can I build such a system?

One avenue I thought of is to make a synchronizing trigger that can for example start multiple surround sound systems together to get me over the 10 channel threshold. Is that as simple just trying the play buttons together? Would I hit grounding issues in this case? My signal processing knowledge is still shit

Is there another way to build a unified system?

>> No.1280607

>get 10 speakers
>get an audio interface with 10 outputs
>put every instrument on a mono channel in a DAW and route it to the relevant speaker

But it won't really give you the sound of a band playing in a room if that's what you want to achieve.

>> No.1280611

>>1280607
Wew I really didn't realize you can get that many outputs on interfaces.

I'm mostly interested in simulating orchestral

What if the requirement changed to 50 ?

>What if the requirement changed to 50 ?

It's possible, I haven't worked with that many channels of output, but I do know that there are many mixing guys that route back 100+ channels into their consoles through D/A converters. You might need to buy several receivers or something.

But tell me, do you record all the instruments yourself? in the same room? I don't understand what you mean by "many dubs of many empty rooms usual shit sound".

Also, orchestras don't usually play in living rooms, so you'd have to use reverb to create the sound that an orchestra gets during a concert, which would mean spreading the reverb return of instruments into the rest of the outputs to simulate the way the sound of each instrument would spread around a big concert space.

tl;dr the idea isn't very good and composers don't actually work like that.

holy fuck, those things are expensive - they any good?
For this, assuming all in same room etc. Id stay analogue, maybe ebay old protools setup, or link a few multi-channel consumer cards together (M-Audio 10 channel Deltas, w/e). Add in distro amps / speakers etc, starts adding up as well tho. I got enough shit lying around to set 50 channels up if the need takes, most audio/equip freaks would have, just, theres literally no reason to. Dont think OPs project/idea whatever is actually all that dumb, be at least interesting, but 50 channels probably way overboard desu.

>> No.1280695

Yes this is the kind of thing I had in mind. How do you link sound cards together? Disregard speakers and amps. What does the software/hardware setup look like for this kind of solution? I have a pile of old computers to dedicate to such a solution

>>1280622
Thanks for the info. For a clarification example say I want to have a 20 violins and piano. I own two very nice condensor mics, a mostly empty house with some sound treatment. I would record the 20 violin files (recording in a dead room or a not dead would need experimentation) rout those to 20 speakers (setup would also need testing) and play piano live. Digital reverb A SHIT. sound character does change between many sound sources in one or two mic's vs tons of single sound sources dubbed over each other.

Yeah it's called phase masking, and it will happen with the setup that you plan because playing them together side by side on different speakers is essentially the same as mixing them together (dubbing isn't practiced professionally ever since the days of multi track tape recorders).

>Digital reverb A SHIT

Digital Reverb is used by the top producers in the industry for orchestral stuff. Unless you have a dedicated reverb chamber in your home (which I doubt), your music just won't have the same impact - especially if you record in a dead room.

>> No.1280710

>>1280701
>Essentially the same
I have heard and used the digital solution. It will not be the same as what I am proposing. The more channels there are the more divergence will be apparant. So yes, virtually the same for 2 violins. I think 20 will be very different quality. Not to mention the sound floor from 20 tracks vs 1 in a pianissimo section

Which will give you the sound of a room, not a concert hall or chamber, and thus not the sound of an orchestra.

Go listen to his music. He did everything himself and followed his results. Along the lines of OP is thinking about, each microphone will pickup or miss certain aspects of the voice, by using several and combining them, he developed a sound for his studio. You may think it's stupid, you siting in front of a computer, making your own music, but he built his studio, played the instruments, recorde, mixed, and he himself pressed the albums, all in a little Bumfuck town in Nigeria.

I don't need to listen to his music to know that it's a dumb idea. I've mic'd up plenty of instruments and singers, that's not how you mic up a singer, the mics will NOT pick up different aspects of his voice (they're the same type of mics), and what's more, they'll actually cancel each other because of phase differences and make it all sound like shit. Don't expect a reward for doing useless shit just because it's special.

I also built my own studio, write my own songs, play instruments, record them and mix them in bumfuck nowhere. There are thousands of people doing the same thing, with the slight difference that most of them actually bothered learning and understanding sound theory instead of just jumbling a bunch of mics of the same model on a narrow sound source.

Audio pro's correct me if I'm wrong but If you want a crisper sound with more depth I'd assume it would be better to have lots of different sized drivers hooked to non-overlapping band-pass filters tuned for each specific one so you'd get better audio definition.

>> No.1281030

Then first thing you need to do is get a decent microphone so you can measure each driver's crossover frequency and map its response curve. Then you can figure out which speakers will handle what ranges and solder together your band-pass filters.

>> No.1281032

>>1281014
Theoretically yes, but that's for constructing a single full range speaker.

If OP had 20 band passed speakers each playing a different track, it'd sound like turbo trash.

If the goal is to emulate an orchestra, the closest and cheapest way is to get 5 or 6 speakers, and slap some reverb and chorus on it.

It's futile to replicate 20 uniquely acoustic instruments with speakers from a spectrum perspective but also a sound direction standpoint.

no, you take whatever gear you have, get it in phase as much as possible, EQ it to cancel out room resonances, adjust the compressor to squelch inputs that are clipping, and then slap a big fucking padlock on the rack.
when some fuckhead customer asks for more "crisp" or "deep" you nudge the programme volume up very slightly. then later on you bring it back down, because this shit is unending and after a couple hours you'd be against the stops. nobody ever asks for less. deaf cunts

>>1281103
Not too complex honestly. You will have to write custom software and make the circuitry, but it's just paralleling out tons of DACs. You could get away with the digital side of the circuitry with a computer compiling multiple digital sounds into a single high bitrate digital stream which would then be passed either via USB or other suitable interface to a microcontroller. The microcontroller would then have to have multiple DACs attached to it to which it would split the data and stream digital sounds at a regular data rate. Pretty sure any semi modern 32 bit microcontroller would be up for the task and your biggest spend would be the DACs and the time you'd have to put into it
