Looking to use JAMULUS for ADR practicing.

[Montxo]

Hello,
I am sending this message because I am trying to find a way to use JAMULUS together with an ONLINE CLOUD application used for ADR Dialog Replacement education users.
Please allow me to explain about this more detailed.

I have developed an online CLOUD web site www.idoblaje.com to allow the Users (teachers and students) rehearsal and record voices for films, etc. to users connected to this site.
I already have a working site for practicing recording and review for the dialogs. This is working well now.
For effective and good educational sessions the users need a realtime audio communication for rehearsal:

For example: 4 or 5 students and 1 instructor professor are connected at their own homes, each one of them connected to the www.idoblaje.com site. We are currently using ZOOM for audio communication and sharing the professor display but…..
The audio latency for the students and very very high so the connected people cannot hear in “realtime” the audio that they need to while looking to the shared Instructor screen.
This is an capture of the current ONLINE application:

So, I would try to find a way to add the low latency features of JAMULUS to provide AUDIO communication between the simultaneously user of my platform to practice and study DIALOG REPLACEMENT.

Anyone can let me know how can I do this or in fact maybe to hire a Jamulus programmer to add this task to my app or make an special version of JAMULUS for me?
I can give more details to someone interested to talk about this project.

Thanks a lot in advance. Take care.

@Montxo

Jamulus is open source. The developers are not paid for developing it. You are free to pay someone to add features for you but your use is, of course, bound by the licence, which is GPL 2.0 (or later).

@DavidSavinkoff I'm afraid Jamulus is distributed exclusively under the terms of GPL v2 - we do not as far as I am aware say "or any later version" :-( So we're just like the Linux kernel :-)

We DO plan to have an exception statement to allow distribution from the Apple Appstore though, but that's a bit of a different matter.

Are you sure? The linked file is a copy of GPLv2 and I assume that it will always be that.

The code -- and I think this is what matters -- explicitly mentions This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.

[gilgongo]

@hoffie Ah - so it does! :-) In which case, the question is has it always said that? In which case we're OK (although the "ASP loophole" we discussed still exists).

[hoffie]

In which case, the question is has it always said that?

The initial version commit (f787f8d) already includes it, so it has been there for a very long time. Can't verify for the pre-git versions obviously.

[gilgongo]

That's good then. I guess I must be used to seeing distributor preambles in licence files under which the licence is then pasted, so Github fooled me into thinking we were GPL v2 only. I don't think it changes anything though.

I'm not sure that Jamulus would necessarily help. The purpose of the low latency in Jamulus is so that the participants in a group can hear each other approximately at the same time, which is important for a group of musicians playing together.

It appears that the requirement above is to synchronise the audio with a video stream. A video stream will have its own latency, which might be different for different participants watching the same stream. Jamulus would not necessarily help with that.

Or have I misunderstood?

[Montxo]

Hello. The sync between video and audio is already resolved in my web appilcation. This already record and replay in sync the audio with video.
What I am looking for is, exactly what you mention: ACTORS (students) and like the musicians. They need to hear each other "ACTORS" playing his role at the same time while rehearsing before they record their roles in my web site.

It is exactly like the musicians requirements.
Just hear each other at the same time to play in sync.

Sorry if my english is not too good to explain accurately.
Hope this help you to understand.

I don't exactly understand your requirements, but running Zoom and Jamulus at the same time is very possible and used, for example, for the WorldJam concerts.
Just turn the audio in Zoom off and use Jamulus for the audio. You get low latency sound of Jamulus and the Zoom typical high latency video.

[Montxo]

Hello. thanks for the reply.
We will use ZOOM to share the screen of ONE of the participants. It seems that when sharing the screen the audio transmision has a better lower latency... but audio of the rest of the participants (not sharing screen) has a high latency. So this is the reason we need to find a way to provide low latency to the NOT SHARING PARTICIPANTS.

[chrisrimple]

It seems like Jamulus, without modification, may provide you with what you're seeking: multiple students able to hear each other (and the instructor) in "real time" and respond. This the same for musicians and choral singers using Jamulus.

BUT, the latency that students experience will depend on their physical distance from the Jamulus server. If you want near-real-time sound, everyone should be within 500 miles of the Jamulus server.

[Montxo]

Hi Chrisrimple. thansk for the reply.
Then the critical issue it to set a JAMULUS server within those 500 miles. Can anybody help me on how can I do this? For example, I would need a server in MADRID SPAIN at the moment.
Can anybody help for this? THANKS.
