“DAC makes the difference!”
So, let’s talk a little about it…Shall we?
Let’s say, that you want to replace your old computer, it is noisy, slow, consumes much energy, etc …
But you also want something economical, low power consumption, that it can manage the lists of your songs on your hard drive and it will be user friendly.
But most importantly, you want to be able to play with the highest quality sound, all of your digital files.
Welcome to the world of Raspberry!
In the above chart we can see that through network we can connect to Raspberry, which runs a server OS (Runeaudio, Archphile, Volumio, etc …) and we can manage/browse our digital files from any of our devices (Computer, Tablet, Smartphone, etc ..).
Well, now you have got the big picture!
But where is the BIG secret ?
In I2S protocol!
I2S, also known as Inter-IC Sound, Integrated Interchip Sound, or IIS, is an electrical serial bus interface standard used for connecting digital audio devices together. It is used to communicate PCM audio data between integrated circuits in an electronic device. The I2S bus separates clock and serial data signals, resulting in a lower jitter than is typical of communications systems that recover the clock from the data stream.
All your digital equipment (CD players, USB DAC, etc..), uses the I2S protocol to deliver you the digital sound.
With the Raspberry and the Mamboberry HiFi/LS/HD DAC+, we plug in the DAC on the Raspberry and in the GPIO interface. So, we have the SHORTEST! path. This is the key element. This is the factor that will deliver us the perfect sound. The sound that no other device can bring.
Now, let’s see what is the software we need.
First of all we want an OS for our Raspberry.
Download the latest image release for your Raspberry Pi version:
Volumio 2 – https://volumio.org/get-started/
Runeaudio – http://www.runeaudio.com/download/
Archphile – http://archphile.org/download
Once download is completed, extract the content of the .zip file with a compressed file manipulation utility (for instance: 7-Zip on Windows, Zipeg on Mac, Unzip on Linux). You will now have an .img (raw disk image) file.
Then write the extracted .img file to your SD card, following the instruction of one of the following guides on elinux.org:
Plug in your Ethernet cable, power up and voila!
You are not happy with the GUI you see? No problem…at all!
The only thing you have to change is the software – client you are using, not the OS on which the Raspberry runs.
These programs called MPD-Clients and you can see some of them on our page …
For example we will take the Gmpc client and we will show you what it can do.
Some pictures of GMPC…
The unique and beautiful GUI:
The preferences page:
And the official site of the client:
As you can see, we can have enough information about the track we hear such as, the lyrics, the Album in which the track is, the band or the artist and much more…
We have no restriction in choosing any MPD client that we like mostly. We can have, one MPD Client in our mobile, another on our computer, another in our tablet, etc …
It is awesome!
We will inform you in the next days about “tricks” and “hacks” that you can do in your raspberry, to add special features and other “small” things that will make your Raspberry more user – friendly, much simpler and your life easier.
It is time to let yourself enjoy your music.
