Has anyone solved Flash Audio echo problem?

Any service which uses Adobe Flash to transport two waylive audio, ( for example an audio calling or conferencing app ),will encounter audio echo and feedback when both parties are in a non-headphone environment. Unlike Skype, which can cancel echo and feedback when used without headphones, Adobe Flash fails always. Has anyone heard of a solution to this ? Possibly with server-side echo cancel ?

Ashod,
Unfortunately, with flash, you don't have access to the raw audio stream coming from the microphone. A bug report on adobe's website explains in more detail.

http://bugs.adobe.com/jira/browse/FP-273

Basically, it states: "Flash player has no AEC support yet. There is no AEC support in Flash player 10 beta also. Developers need built-in AEC to create convenient webservices with live audio/video communication without requirement for user to have a headset. According to Speex project website Speex supports AEC."

Hope that helps!

Greetings Ashod!

Could you provide me with more information, links, code, application, etc. that I can use to recreate and analyze the problems in my spare time?

I take it this is some application you are writing. I will sign an NDA before you send me anything if you need me to.

Have a Great Day!

A quick and easy workaround is to require everyone to use headsets. There are obviously circumstances where that's not possible or less than ideal, but it should be noted as a non-technical solution.

Adding a push-to-talk feature can also solve the problem. This will mute your speaker as well as all other microphones in the same room when you are speaking.
