A method for check the consistency of a data is send it more than ones and compare it so this is a common way for check the consistency of a data transmission.
The digital signal and the digital world in general works with a boolean logic. Now I simplify guys but I always advice to read books or find reliable sources no video of someone. Example you send a message to your friend and this message is “A” you can get 2 results your friend receive your message “A” or your friend receive nothing. In no cases your friend will receive the message “B”
If we’re talking about the message being one letter (“A”) then yes there are two possible outcomes. “A” or nothing. But what if the message is the previous sentence and we dropped all the "a"s? It looks like this:
If we’re tlking bout the messge being one letter (“”) then yes there re two possible outcomes.
Now read the original and compare it to the one without "a"s. Did your friend receive message “A” (the original sentence) or nothing? Neither. He received “B” - a message that isn’t the original.
You have to minimally run a 19V PSU for the pi2AES, at least to run SPDIF or AES, the cheapest option is the meanwell 24V PSU they sell on their site.
I recently upgraded mine and it does make a difference, but it’s a good device even with the Meanwell option.
The pi2AES really isn’t the “cheap” option that video makes it out to be, but it is very good for the price, a lot of comparisons with other options over on SBAF.
It is, and if you knew how a digital audio format like a pcm looks like and you knew how a DAC chip and a microcontroller work that was pretty obvious . I answered hoping to help someone willing to understand how it works but since you don’t know it and you’re not willing to understand it, you don’t deserve help.
I saw an improvement switching from the SPIDIF Coax to the BNC. Make sure you’ve got a good cable. I made my own… I mean I bought a really expensive one at deep discount.
The problem here is that “Digital is Digital” is not true to begin with. CAN, USB, Ethernet, etc. all use differential signals. Does not mean I can plug a Car into a network switch.
The next issue is that the real world does not care if your theory works on paper.
Extreme example, but a square wave through some suboptimal trace layout and cable can easily come out looking like this:
A Schmitt Trigger may help to get that to be valid data, clock accuracy is lost on those rolling hills.
If digital was so easy, how do you explain all the forum posts elsewhere of people debugging I2C (and similar) protocols?
Since the last time we had a discussion about the volume control you said that the pc via the usb cable transmit an audio signal to the DAC I can understand your confusion but digital is digital
I had some noise issues due to interference from my pc tried every connection, optical usb. ended up getting a schiit Eitr, hooked up to my Schiit gungnir by coaxial and haven’t had any issues with noise. i’ve tried other dacs with usb, they still get noise but with the Eitr there’s nothing. For only 99$ Its been the best upgrade I’ve made, the noise was intermittent but totally gone now after awhile of use no issues.
