hey,
i have six speakers in my multiroomsetup.
I want to use the beocreate to controll 4 speakers separately. How can I do this? I read something about crossover and DSP-Programming. Please give me some infos to start my work.
Is this howto usefull for me? https://github.com/hifiberry/hifiberry-dsp/blob/master/doc/crossovers.md
the two other speaker i want to controll with my secound raspi (and an amp-board), but this is no problem.
I'm not really sure what you want to do. While the Beocreate is a a-channel amplifier, the interface to the Pi is 2-channel. You can't play back 4 independent channels from the Pi. Is this what you want to do or do you just want to use different volume on different output channels?
Good morning,
i want to play each channel separately.
At the moment i have the problem, that i stream musik in kitchen and living room. ("channel 2").
I want to choose kitchen - OR - living room on my iPhone.
And after a few minutes of search I had read, that is (tricky) possible to use beocreate with 4 mono channels, who only one (Speaker-wire) is active. Some users say "hack" / "hacky"... but hackig is another thing for me.
My idea:
(Left Side House)
- living room (beo)
- kitchen (beo)
- office (beo)
(Right Side House)
- bath (beo)
- hall (AMP2, not beo)
- bedroom (AMP2, not beo)
I want to choose each room seperatly OR right/left side OR all together.
If you're okay that all play the same music, it's possible. However, this will require top create your own DSP profile with switches or volume controls for each speaker. You can control these by setting registers on the DSP (yoiu need to learn about the DSP and its memory first). There is no UI for this, you would have to implement this by yourself.
While the hardware could do it, there's quite a lot of programming required for this.
Thanks for your Answer,
all together and left/right works already. this was the easy thing.
Can you give me some more infos about dsp/beocreate/monocontroll? i need the first (2-3) steps to start my research.
When I open Sigmastudio there are 30 processors to chooose... whitch has the beocreate?
Really bad that I have to programm something for using 4 speakrs seperatly.
It's probably best to just check out one of the project files that we use:
https://github.com/hifiberry/hifiberry-dsp/tree/master/sample_files/dspproj
In general I would not recommend this as a beginners project.
please wait - i post a new answer.
So i study the program sigmastudio. And now i understand some more about the dsp.
Step one:
This is the input part. It seems that four inputs convert to two inputs. right? Maybe i have to remove Nx2-2 to create the abilitiy to use four channels? Or have i to add another nx2-2 (3?) and connect B-IN 12 & 13 to the new nx2-2(3) and remove the wires to Nx2-2?
Step two:
This page allows only to change volume at two channels. (= controll two speakers at the same time). So i have to add also B-In / B-Out?
Step 3:
I have also on this page add two more channels (left, top). Whats about the things signal detector, unmute, check asrc... any changes necessary?
Step four:
Copy the both and connect with my new channels?
Step five:
Copy all of this and change B-IN / B-Out to my new channels?
Step six:
In this page I think there is more to be done. Is this right or is my logics wrong?
Step seven:
In this pircture i dont know what i have to do. maybe nothing? some usefull tips?
Thanks for your help and i hope you understand what i have to say. My last english-learning was 9 years ago.
Important to know: I only use one or two inpus at the same time. I want only have the possibility to use the four channels (EACH SEPARATELY) with maximum two inputs.
The 4 inputs that you see in the profile are 2x SPDIF input and 2x Raspberry Pi input. Both SPDIF and Raspberry Pi are limited to 2 channels. You can't use 4 channels from the Pi.
You can split these 2 channels into 4, but it will only be 2 independent signals.
Only two independent signals are perfect for me. I only want to choose signal one in kitchen and signal two in living room. And if i dont use kitchen and living room, i want to do the same in office and bath. Or in bath and living room. Or in living room and office.
At the moment i have the problem, that the signal is in kitchen and living room (e.g) at the same time. for this reason i want to change the dsp.
Can I use the 4way-iir.dspproj as sample for my beocreate? so that i put in my changes and flash it on the beocreate? Or this sample cant used for this, cause this is for another amp/chip....
You can basically use all profiles from us, but you might need to adapt these. Specifically the MUTE control is different for the DAC+ DSP and the Beocreate. MUTE on the Beocreate is active HIGH, while it's active LOW on the DAC+ DSP.
Good morning, thanks for the tip.
That means the samples are not for the beocreate. Why are no samples for the beocreate available?
I have to try in many hours and really professionals have it done in less a hour.
It's really bad that there is no ready-made solution for this problem. Especially because my request has been made several times and it doesn't seem to be a problem technically.
I've been working with linux and ubuntu for many years. it also works well because there is great documentation. With the Hifiberry beocreate it looks different. Really documentation means this sample..https://wiki.ubuntuusers.de/Startseite/ or https://wiki.ubuntu.com/
Documentation with hifiberry beocreate means...
- a "layer" picture (ports, pins...)
- howto install sigmastudio..
- install dsp..
- "you have to do it on your own"
i would like to work out the solution (and share with comm), but the help and documentation is simply not enough. If there was at least one -real- example of beocreate, that would help. How should I know - WITHOUT MUTE DOCUMENTATION - how something goes from low to high.
Thanks for the really big help - not! that shows how important support is................
I have it done on my own.
At first: Thanks for the advice (not - i know i am funny), that BO have the right dspproj in repo already. (https://github.com/bang-olufsen/create).
So i downloaded it, add 4x mute (adress 0x1303 - 0x1306), activate logging in shairetunes (fork)/LMS, control every 5 secounds the log, and mute/umute the channels via dsptoolkit.
Its not the perfect way but in my case it works.
A new try for good support:
If I want to add-on my beocreate (amp2), what have i to do?
(sigmastudio, adresses, mute?). I dont want a secound raspi.
