Diretta audio protocol

[OrigTweaker]

over 2300 euros was invested just to the parts.

Wow! My own Ian Canada + Diretta concoction pales in comparison, but sounds great for less than $500. The trick is using two Raspberry Pi’s linked by a completely isolated network without any other traffic, error correction or control signals.
Explained here.

Just here to say a few things:

1) Thank you so much for this guide.

2) I have had Gentooplayer and Diretta ASIO working on my Holo Red for awhile. For some reason I never had Memory Play and THIS is the way to listen to Diretta. I wish there was a better player interface and it played mp3's, but it is the best for FLAC and WAV by far.

3) You don't need to download and install Diretta Memory Player separately. It is included in Diretta Tools. When you click MPlayCtl from the Tools program it launches the version within the Tools folder anyway. So downloading Memory Player is not needed. Memory Player is offered there separately just in case you are running a Diretta Host somewhere else. There is no advantage to running the Host on a different system if you run everything from Windows.

Okay, folks, I'd weigh in here on a project a good friend of mine has undertaken. He's convinced me to follow him down the rabbit hole.
Here is the link to the Diretta Project on GitHub

I am currently running this solution on two Raspberry Pi units: A Pi4 running as the Diretta Host and a Pi5 running as the Diretta Target.
As of this morning, I have Diretta Mode3 implementing DDS "Diretta Direct Stream" in place of UDP atop the latest version of AudioLinux 4.6.

While David Snyder, the fellow behind this project, focuses much of his work wrangling Roon, I decided that I'd like for it to be less of a "uni-tasker", so I now have RoonBridge and MPD UPnP and its associated client running in tandem. This way I can run either Roon or Audirvana, but not both simultaneously.

Below, I have screen captures

Have fun tinkering, for those who take such pleasure

The latest version 147 really DOES sound spectacular, let's just hope that Diretta won't go away too soon

This isn't about contractual obligations or what's "owed" ; it's about the reality that Diretta is under significant financial stress and needs support to survive.

Those who DO find the last version spectacular also found the previous versions spectacular

Reminds me of this Groucho Marx joke:

French forum user LeDom has made it easier to use Diretta by implementing a UPNP link with a Diretta endpoint:

GitHub - cometdom/DirettaRendererUPnP: The world's first native UPnP/DLNA renderer with Diretta protocol support

The world's first native UPnP/DLNA renderer with Diretta protocol support - cometdom/DirettaRendererUPnP

Give it a try!

One thing I am curious about is the claim that this "bypasses OS audio stack entirely". This claim is somewhat misleading, in my opinion, since it is unrelated to the use of the UPNP protocol, and only depends on how the the "player" outputs a digital signal (to the DAC). So I would be curious to know if Diretta "Memory Play" really does bypass ALSA. Somehow, I doubt it, but who knows (the Japanese developer does)?

For all my audiophile peeps and geeks in the San Francisco Bay area, I heartily recommend attending this Digital Streamer Shootout, where my good friend and partner in tech-crime David C. Snyder will be demonstrating and talking at length about the DIretta Project, of which I have become closely involved.

Audiophile Foundation Digital Streamer Shootout Featuring The Diretta Project

Here is a GitHub link to the project: Diretta Project
The Diretta Project's initial focus was/is Roon, but for those either not familiar with or not friendly with Roon, I have made a point of making sure that it works with software via UPnP, for example, Audirvana, among others.

Mark this event and make sure to attend, as David C. Snyder will actually be on hand to answer your questions. This is a rare opportunity. And if the fates allow, I might make it out there as well.
