AEC 10.3 swc

Avatar

Level 10

Hi ,

I am just putting a drop of LCCS 10.3 swc that supports echo cancellation based on player 10.3 beta release yesterday. Its a local build for me and not tested and it doesn't have the multicast stuff either( as I just built it on our player 10 swc). I just wanted to throw out something for ppl to try out echo cancellation.

I am attaching the swc

Things you will need if you are using flex builder

a) you need to have additional compiler option as -target-player=12

b) You need to have the 10.3 playerglobal.swc in your Flex SDK

c) You need to have flash player 10.3 installed on your machine.

Since there are additional classes , we will in future have to give out a new swc for 10.3 in all likelihood. But for now, test and let us know how AEC works for you.

Hope this helps

Thanks

Hi - is there a Flash-compatible version of the LCCS API swc with AEC?

Hi Nigel & Arun,

Thanks for referring me back to this thread in your post on AEC in http://forums.adobe.com/message/3709913#3709913.  That's great that you have an prerelease AEC version of the swc for each of your releases.

Since I'm using the prerelease swc (and source code) that includes your initial CPU spiking/ratcheting fix, does that also include the code necessary to test AEC?  If not, would it be possible to get the swc and source that includes both the CPU spiking/ratcheting fix and AEC?

Much apprciated,

Hi Trace,

We build and release the 10.3 swc along with our regular release. So

10.3 swc would have all the changes we made since our last release. So

you can expect the 10.3 swc with the CPU spiking/ratcheting fix in our

next release which is very soon.

Thanks

Ah great - thanks Arun.

So just to confirm, that 10.3 .swc and source code will include access to AEC as well?

Thanks,

Hi Trace,

We werent providing src for 10.3, but we could provide one along with the next release.

Thanks Arun, having access to the source to 10.3 will be very helpful for debugging.

Will that have AEC, or if not, could another AEC patch (with the understanding that our mileage may vary) be made available?

Just to confirm, based on items from other threads, you do echo cancellation for us and we don't need to set

  view.audioPublisher.useEchoSuppression = true;

or

  view.audioPublisher.codec = SoundCodec.SPEEX;

right?

Thanks,

Hi Trace,

useEchoSuppression by default is set to false, and codec is set to SPEEX by default. But AudioPublisher.useEchoSuppression is a wrapper to the "Reduce Echo" field in the Flash Player Microphone settings panel, and "useEchoSuppression" functionality is ignored in enhanced mic (with AEC support)

For more info - http://www.macromediastudio.biz/devnet/flashplayer/articles/acoustic-echo-cancellation.html

Thanks

So just to double-check, you're saying that there's nothing we need to do from our side to enable AEC if we're using the 10.3 SWC then?

We're asking because we've been hearing a fair bit of echo recently even when running under 10.3 with AEC, but the users in question were speaking loudly and there were other computers nearby connected to the same room.

Thanks,

Yes Trace, You don’t have to do anything to enable AEC.

Let us know if you hear echo under a different setting.

Thanks

I have no echo now with the new swc. Audio is getting close to perfect. I still make those two calls in the API, but not sure if it's necessary or not.

Thanks.

I have been out of the "LCCS" game for a few months working on php for a project, so I apologize for my ignorance here, but am I correct in thinking the AEC 10.3 swc has not been officially released yet?

I just reinstalled the LCCS SDK Navigator, as well as downloading the latest SDK, and the library is still at version 10.1!  Am I missing something or is 10.3 still in beta?

Thanks,

Hi Matt,

Yeah, it's not quite released yet. Very, very soon though. The swc in the

forums here works pretty well though.
