Get started with the Raspberry Pi High End Audio DAC

This is a High End Audio DAC designed for the Raspberry Pi 2 or 3. Using Volumio it can be used as a stand-alone networked Audio Player and operated through a WebUI.

* Dac to play Hi-Res music
- User: Play mp3
* Dac: Am i a joke to you?

This video has such style. I’m watching it again :)

[jungtarcph]

that was a great intro.... where is the rest?

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....

Amazing! How did you get the TFT working with volumio? B-)

[jorgeenriqueotero]

Can I use it to recording audio for example a sensor with 0.5V with 192kHz?

[guyseide]

Did you have to install additional software to make the monitor work ?

[rutu]

Hi, did the different hats not share the same GPIO pins is that how you stacked them?

[ubacow]

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

[angelor]

how do i configure the monitor to make it work on volumio?

[pngun]

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.

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???

[stakesishigh]

I want all this, but on a larger touch screen monitor for a man cave.

[fabiuh]

well i need a 6ch output dac for a RPi, any advice?

[Dondiplus]

Hi, is it possible to use it without the screen mounted on it? or it could be harmful ?

[JeanPierreVazquez]

This is really neat except for there not being a case to wrap everything up nicely.

[aurelf]

130 euro for this ?with this you can buy an entire dac sistem /come on ....

[nopochoclos]

Hi end audio dac and play mp3 in the video... please kill me...

[ambcog]

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.
