LCCS Audio Feedback issues.

Working on a video/audio chat project and I am dealing with a ton of feedback from certain computers in regards to the audio. I tried adding the UseEchoSuppression flag and that doesn't seem to help.

I have notice other flash video/audio chat not having those issues (testing it on the same machine that has issues with my LCCS app). Is there something in regards to best practices or any documentation on how best to set-up audio on LCCS?

I tried using the Audio example in the LCCS sdk as well and get feedback.

Any help would be great!

Thanks,

Romke

There are a lot of questions that needs to be answered before p2p. Which

SDK .swc you are using 9,10 or 10.1 ?

If you are using 9, there is no p2p since flash player 9 doesn't support it

If you are using our player 10 swc, then you will get the p2p with a

maximum of three streams

If you are using our player 10.1 swc, then you will get p2p with

multicast with as many p2p streams as you need.

The default is always p2p if you are using 10 or 10.1 unless you have a

older player, a non-rtmfp connection or a firewall.

You need to refer to our developer guide for more details on p2p using

10 or 10.1 .

Thanks

Yeah flash does not have acoustic echo cancellation so without

headphones you will get feedback. That echo cancellation you see now

really just turns down the mike gain. We've all been fighting this

for years.

There's a long standing bug with the flash player team about it. The

good news is they announced in that bug the other day that AEC will be

in the next beta release of 10.2 so cross your fingers

Thanks for the heads up on the status of the AEC implementation esteimle.  That's great news - can't wait to try it out when it's available!

You might want to try SoliCall. It will do AEC for you (either on client or the server side) and is available today.

Have you tried SoliCall? I'm curious about the performance.

Yes - it works very well. You can easily try SoliCall Pro. It dramatically reduces echo/feedback

I have the impression the echo problem was NOT fixed in 1.2. I'm surprised this is not a top priority for adobe. We should receive at least the quality such as free services like skype. also the price for voice should be lowered.

Hi there,

Echo cancellation has definitely been a priority - sometimes "priority"

means that we need to take extra time to make sure we get it right. I can't

promise release dates for the player team (Mr. Basu took a stab at this, to

our peril). I can tell you that we've been testing an internal build of

an upcoming player release, in which echo cancellation is working really

well. It should be coming out later this year. We'll let you know when we

have firmer dates. And you do realize we don't charge more than

$0.01/user-hour if you're doing p2p voice, right? It's hard for us to charge

less than that without losing money.

thanks,

nigel

I pray for quality....cause I cant post my app otherwise  Im afraid we must reach skype quality as minimum.

I use


    import com.adobe.rtc.collaboration.AudioPublisher;
    import com.adobe.rtc.collaboration.AudioSubscriber;

how do I make sure users stream with p2p voice?

any disadvantages in regarts to p2p voice?

THANK YOU FOR YOU GREAT WORK!!!
