Anyone know how to dual stream DJ?

[IMGypsy]

I use SAM2014 and so does my partner - we want to dual stream strictly using SAM.  Anyone doing it now?  or if you dual stream using another way, please share.  Thanks

as land only can have one radiostream one would have to broadcast on media, but due to latency and different servers the result may be VERY disapointing, and people need to have media and radio on

the other way would be you create a server at your side and combine the streams on that before sending it to the www

SAM2014 is the broadcaster (shoutcast stream) - broadcasting is no issue at all I am a seasoned DJ the problem is the dual streaming setup. Yes it can be done but I need to understand how to set up SAM to do that.

IMGypsy,

You can dual stream. It's done as follows:

1) Pick which of you will be the on site initiator of conversations and/or the beat keeper of the musical performance. You are the driver of the performance and you have to assume that your co-host will be filling in along with your conversational cues. This is important since the 2nd party will be reacting real time to your conversational or music cues by monitoring your stream as it arrives in their SAM session and as they rebroadcast it + thier voice to the parcel you will be entertaining on.

2) Your 2nd party guest host then adds your stream to thier Play Queue using the Add URL option with your stream and port information. This should be set up in Deck B of thier SAM Session.

3) They add thier own live mic stream to thier Play Queue using the Add Mic/Line option. This should be set up in Deck A of thier SAM Session.

4) Your 2nd party guest host  should be monitoring the AIR transmission with thier headphones. This is the combined stream of your stream + the null feedback [or live feedback] of thier own conversation and performance.

Now, getting the conversational hang of being the 2nd voice takes a bit of learning since you are not actually conversing. It's more like you become the follow on color announcer in the stream. When you get the hang of it is sounds pretty good.

I' e done this a few times with so-so results but that was because both of us wanted to be the lean in the conversations...

This is a bit cludgy I know but otherwise you need a high-speed interent connected mixer in both your studios to do the mixing before SAM.

Option

Now if you both run your own DNAS servers on your own PCs you can eliminate one side of the buffering delay issue by encoding and using the internal port feature to feed the stream to your local DNAS.  If you both have excellent symmetrical Internet Service [High Speed both up and down] you can and can cross stream to each other and listen in to the Air Feed with only a sub-second delay. This allows almost synchronous chatting like in a in studio live show.

By High speed I mean 2mbps / 2mbps minimum.

Then one of you starts a 2nd encoder as the stream source to the relay service for the parcel. This should be the one who has the PC with the most processors available.

In any case, you need a 3rd party to test with that can listen to and record the overall effect and give you the needed feedback so you can fine tune as necessary your delivery and performance and SAM/DNAS settings.

Under no circumstance should you try to monitor from SL and the parcel stream.

This information is definitely valuable!!! Thank you. Crossing my pixel fingers. Thanks.

KarenMichelle, my friend is starting up a karaoke club, which led me to wonder about latency issues. Is it possible to do this? I mean, can someone sing along with a music stream and not be lagging it by a half second or so??

[IMGypsy]

I think it depends on what they use as the Karaoke - now I do have the Monkey Karaoke board inworld - however have not used it yet. There are specific places to use on it like SingSnap.com and some others. Bottomline is that we are becoming more sophisticated SL'ers. And it's the technical aspect that can elude us but dig dig dig - we want it so we will do it.

In a pre-planned karaoke situation, the person singing needs to have the music stream coming in from the source in pass-thru URL Mode via their PC Broadcast Solution where they can hear it on the "On Air" Deck A while they sing to it on the Line/Mic input on Deck B. The resultant mix is then encoded and streamed to the club Parcel. Unfortunately, most karaoke singers are not going to put out $$ for Broadcast Software to accomplish this.

This is also one of the ways the folks that sing together can use to layer a vocal onto someone else's performance.

But this so does not work in the in-world open mic karaoke situation. The Music URL connects to the standard Music Relay service for the Parcel and will be delayed from 0.2 to up to 20 seconds to the ear of the person singing to it. While they may be in-tune and tempo as they hear the stream, the rest of the audience will have variable delay of the source material. The singing that you hear on the Lands Voice channel will always be a bit be out of sync.

I need to play with the Monkey Karaoke board to see if it blacks out the music source channel and redirects the blended performance to the Music URL relay stream or the Voice channel.

well Karen, if you need to test a board come on over and play with our board all you want!

[KarenMichelle Lane]

I will so take you up on that invite when I get in-world with time to spare.

[IMGypsy]

great!!!

talk about a "double stream" is really propagate a wrong concept. In SL stream that can be shared is always just ONE, set on parcel. Then outside SL you can use any sort of trick and tool for do something with others, but what come in SL is always a single stream. Fake.
