Any experience with AES67/Dante?

Post by erlkönig »

Hi all,
i'm going to do a live show on saturday which i want to record multitrack with up to 30 channels. The desk knows Dante. I know about merging technologies module and its daemon, but this is limited to 8 channels (never tried it).

There seem to exist a different solution with gstreamer. I found the following:

https://github.com/voc/aes67-recorder
https://github.com/philhartung/aes67-monitor
and (for testing purposes) https://github.com/philhartung/aes67-sender

So, has anyone experience with this (merging technologies included)? Can you provide some hints, tips?

I going to try to make the gstreamerthing happen, it seems to me to be easiest.

edit: there seems to be a third solution:

maybe i will give this a try because i'm little bit familiar with sox and rtpdump.

Fiddling with sequencers does not evolve into music necessarily and Mac users have smelly feet and guzzle little children.

I decided to record the raw stream with rtpdump and try to extract the audio afterwards. But i'm still burning for tips!

What type of desk is it? Many recent ones have direct USB recording.
I've mainly used a Digico SD10 with MADI which can record 48 channels at 48kHz. Not sure about Dante.

@sunrat
I know, but it's a Yamaha ql5. I know this desk from several jobs, with multitrackrecordings, too - it doesn't seem to have that option. It was always done via Dante (the housetech made that recordings, but on weekend, there will be another one).

But i found this:
https://github.com/bondagit/aes67-linux ... ree/master

it looks very promising, with SAP and stuff.

Looks like a nice console. I haven't used one.
Let us know how you go getting the Dante recording working.

With the Digico MADI interface I had to use Windows as it didn't have a Linux driver. Always worked fine, except for the time I inadvertently left internet active and Windows decided to do updates. :|

Hi @sunrat,
after spending a couple of hours with AES67-linux-daemon and similar applications, which worked, i decided to go the safe way. I boroughed a Windows-laptop and got the 14-days trial-version for VSC (Dante virtual sound card). The guy who supported the audiosystem at the venue was familiar with dante, and we both are absolutely unexperienced with AES67, so i took the safe way. It was easy: starting VSC, connecting it physically to the console and everything was done. I just had to assign the 32 channels from VSC to ardour and recorded the whole evening (4 bands, i mixed three of them). No more configurationtasks. But it was a little hell getting the VCS: registering at the company, retrieving a serialnumber to unlock it...being confronted with all that licensingnoise (i almost felt like Frodo in Mordor must have felt), i think: in the end, for me, it's not worth to depend on an license that is in the end an act of good will (see the discussion around mixbus). Dante seems to be extremly convenient. But from a technical point of view, you don't have any clue, what's happening (PTP-stuff, multicaststuff...). AES67 needs way more configuration, but with that knowledge, you may be in the situation to recognise and solve a problem easier, i think. The only solution to solve a possible problem with dante ist obviously: switching all off and on again. I don't know what it is like in bigger setups, with PA-system fed directly by dante, having microfones that speak dante, using seperate FOH- and monitorplaces, maybe giving an n-1 to the radiostation...then i don't want to solve a problem that may occure. Dante relies heavily on a well managed network and i have enough to do with sole audio setup...
I had also got dantecontroller for safety reasons, but it wasn't needed. An interesting thing: in the preparation/learning phase, it found my AES67 source, but i didn't investigate further. Maybe in the next weeks (if Dantecontroller runs on WINE, because i have to return the laptop to my friend).
