Flash Player’s Advance Echo Cancellation suffers a serious defect ??

While recently working with the new Flash Player features, i came across a definitive issue in the new claimed AEC (Advance Echo cancellation) feature.

While Adobe says that AEC removes all echo problems that may happen in 2 way communications, i really doubt that the issue is far from resolved. In fact this introduces a new kind of issue.

The AEC algorithm actually tries to clear echoes, and mic feedback residues. However the interesting thing to note is the feedback issue will happen only if you have set Microphone.setLoopback(true); Else you will never need AEC anyways.

Now when you have Microphone.setLoopback(true); and you use AEC to save the day, you will notice that it often kills your own mic feed thinking it to be  echo from the other side. Thus back to my original statement.. we never did solve the Echo problem.

In fact i found a issue reported on Adobe forums that has not been responded to. It seems that the issue happens when you use the EnhancedMicrophone api http://forums.adobe.com/thread/899119

Hence i will conclude this is a flash player AEC bug?? If any one may want to comment on this, and thinks otherwise (that AEC works for you), please let me know.

Avanti GUI + FFMPEG – Open source alternative to Adobe Media Encoder

Avanti GUI + FFMPEG make a perfect open source alternate to Adobe Media Encoder. The Avanti GUI also needs “Avisynth” optionally for some extra features. but basically if you intend to own a desktop tool for your video/audio needs, such as conversions, audio extraction, video extraction etc etc: then this is the thing for you. Avanti with FFMPEG renders Adobe Media Encoder completely unnecessary.

Avanti can be downloaded from: http://avanti.arrozcru.com/

Avanti comes with some rather intriguing tools for bit-rate calculations, fixed file size conversions, size estimations,  frame crop editor and much more. As instructed on their site you need to download ffmpeg executable separately from specified links according to your operating system platform. Just drop it into the ffmpeg folder and you are good to go.
