* Dac: Am i a joke to you?
that was a great intro.... where is the rest?
This video has such style. I’m watching it again :)
Amazing! How did you get the TFT working with volumio? B-)
Did you have to install additional software to make the monitor work ?
I have an important question. I had an idea to integrate this concept into an analog mixing console and have one of these in every channel strip. Interfaces need to operate with bus cables like USB FireWire lightening protocol and those have real drawbacks to audio quality especially in today's lossless Hi-Res and DSD capabilities. Most interfaces right now max out their quality per channel at 192khz 24-bit at 8 channels. You also have latency issue and buffer. My question is, how can we as out-of-the-box console mixers use a individual device with Hiquality playback that can synchronize each and every channels devices through MIDI SMPTE timing clocking synchronization? This compact recorder would be very useful for people with large format consoles and mix entirely independently of a computer DAW or interface over a transfer medium cable. I think in theory it could work. But, in the size that each screen could fit within the size of it's own channel strip at the bottom where your hands rest. With the touch screen, have a way to touch the screen and manipulate parameters and plugins or to have as independent spectral analysis screens....
Can I use it to recording audio for example a sensor with 0.5V with 192kHz?
Hi, did the different hats not share the same GPIO pins is that how you stacked them?
could this be used with pianoteq?
Is there any way to make an audio player that doesnt have a touch screen? I just wanna play songs and scroll through with manual buttons
Mee too. Something like panel bluetooth mp3 modules from Aiyma or wuhuama, but board replaced with Rpi.
Hig End Audio DAC with MP3?
how do i configure the monitor to make it work on volumio?
What are the instructions for installing the DAC drivers AND installing the 2.5" screen? Instructions for the DAC require an audio distro with no screen instructions, and vice versa for Raspbian. Need a step by step.
Kinda looks like a bomb
I want all this, but on a larger touch screen monitor for a man cave.
well i need a 6ch output dac for a RPi, any advice?
5.1??
I want that to integrate this concept into a mixing console with above 32 channels. Any ideas?
It's seems to be more of an audio player.
I wish I saw this video before undertaking my RPi project to build the same thing... Unfortunately, the comment link for details / ordering is no longer valid, and there are no details (or product SKUs) of the components used in the video, specifically the DAC HAT and the TFT Touch Screen HAT. I'm trying to build the same thing with a HiFiBerry DAC2 Pro and an Adafruit PiTFT Touch Screen... and this route is not as easy as your video (very challenging project). Any chance of posting more details or posting a new updated video with new components???
For some reason today I had the same idea. Poor pie is sitting in my drawer for more than a year now....
HiEnd and MP3?
This is really neat except for there not being a case to wrap everything up nicely.
Jean-Pierre Vazquez They have cases available.
If only there were 3D Printers!!!!!
Hi, is it possible to use it without the screen mounted on it? or it could be harmful ?
Hi Paolo, it can be used without the screen without any problems. ;)
@@ElektorTV Thaks ;)
@@ElektorTViam trying for months of 2023 ...only waveshare 3.5 inch comes as Blank Screen bro...even though Touch Display is active and installed in Volumio Plugin section...I connected via GPIO pins...
why not add battery and casing to it
...why?
130 euro for this ?with this you can buy an entire dac sistem /come on ....
True. One that won’t have nearly as many bugs either. But what’s the fun in that?
Hi end audio dac and play mp3 in the video... please kill me...
this is runuaudio not volumio...
Does runeaudio have built in drivers for that touchsreen?
not high end at all
So not high end. Not even HiFi. You're using a crappy DAC. I know this, because there is no high end DAC for Pi yet.
You've added a touchscreen. Screens add noise that's one of the reasons laptops suck for audio.
Switching power supplies suck. Period. Even the fancy ones like the IfI. And you will hear the difference if you're system is up to the task.
And the Raspberry Pi doesn't even put out true 44.1. Not even close to high end.
High end Pi is Pi/Allo Digione or USBridge/high end DAC. With the Pi using an Sbooster power supply, or better. Then you're getting close. Except an SoTM SMS 200 is better, and an Ultra is much better then that. And both get even better again if you use a linear power supply. Preferably an Sbooster, or better. Now that's high end.

www.elektor.tv Oh God! Delta Sigma. Ugh hh! All set with oversampling. Especially with that old chip. Next time try taking the digital filters off. And maybe running the output through transformers. Then you're getting close to high end. Like I said. This is not high end. As it is. I'm sure it sounds funny. Just like every other delta sigma design that's not seriously tweaked.
@@amb3cog this is high end compared to standard mp3 quality built-in rpi sound or any consumer built in audio playback (smartphone, laptop, etc); this project aims to be a pono-like version but based on open source software; you cant compare this $180 solution to $1000 dedicated external DACs; but for $180 is a good step up from said default built-in audio playback of many devices
@@alerey4363 No it's not. That's like saying I own a luxury sports car, and then I pull up to meet you in a Toyota Corolla with fur seat covers, a fur steering wheel cover, and big wide rims with high speed rated tires. You say "I thought you had a luxury sports car?", and my reply? "It is a luxury sports car compared to any normal mass marketed car in it's class. It's more comfortable, and handles better too".
Your logic is completely flawed my friend. Just like there are actual, real, luxury sports cars made by BMW, Mercedes, Maserati, etc
There are actual, real, high end audio DACs, and this isn't one of them. It's that simple. Call it what it actually is.
What I don't get is why you would waste your time trying to defend the person who made this video? I understand why they lied about it. To get people to click on it, obviously. You I don't get at all?
@@amb3cog luxury is totally subjective; on the contrary, facts are undeniably objective; as a totally capable 24bit-192khz playback device, all these (budget, under $200) audiophile boards for the Rpi ARE TRUE high definition audiophile quality; as a 16bit-44Khz (or even worst 320kbps mp3) most mobile phones or set-top boxes consumer devices are not; your silly analogy of luxury objects wont matter here, if I put a "luxury U$1000 jewel case" to a consumer phone capable of only CD qualtiy that doesnt make it hi-res audio device; see how silly you are? now go back to basic physics and electronics classes, then come back when u have some knowledge
