Diretta audio protocol

"Diretta is a new audio transmission technology over LAN (network line). This technology aims to improve sound quality by keeping the load on the receiver constant, with the sending side of the sound source as the "host" and the receiving side as the "target".

I think the best is to load files into RAM and then turn off network completely during playback.

This can be done easily with Wi-Fi but there are new developments with software players which can minimise network activity to nearly zero with copper or fiber ethernet too.

You are right this is a very good approach as soon as you can put the right level of data in ram (DSD files...). I have in mind that audirvana provide this kind of RAM loading/reading, not sure about the other. 
any way having a diretta protocol to feed the ram when it is needed could be a bonus.

 

I think all of the best players provide loading into RAM, Euphony and TAS as well.

Very interesting is the approach of Taiko Audio Server (TAS). This player seems to be able to "clean" the files from network artefacts before playback so the question is if Diretta can improve the SQ further.

What I point is that the idea is nice, implementation is perhaps more difficult depending on the kind of files you are playing and how the ram feeding is done if ram is not enough to feed (Qobuz/tidal streaming, local streaming....).

 

Agree,

at the moment I have only 1GB RAM allocated for tracks pre-load with Audirvana (Qobuz only) and it works fine.

ot makes sense where the player running audirvana or euphony or... is connected to the Dac. If you are using these softwares as servers perhaps a solution like diretta could help. Let me try again :-)

 

You mean a DAC with Diretta input connected to a server with Diretta output?

But even then you have always some network activity between both.

@seeteeyou

Therefore I mentioned that TAS seems to be able to remove network artefacts from the files. That would explain that the files with the better switch sound better even when the network is disconnected (Nenons post).

 

What about the clocking with Diretta, it is not asynchronous like USB.

Here the info from an earlier thread with valuable comments from @Miska:

Is there some feedback in French forums about the new ZERO LINK connection between transport and DAC which is also promoted by Sforzato?

@Miska What do you think about this?

 

Thanks
