Surfing online, often see people asking questions like  this: “Does anyone know how to convert 5.1 AAC to AC3? If so, what software do  I need and encoding/conversion settings. Thanks in advance for any help.” As a  matter of fact, this is a normal question, because some of our usually used  multimedia devices can decode or read audio codec selectively only, we have to  do format conversion to meet their requirements. For example, some theatre  amplifier can only decode AC3 5.1 format, while Apple TV can only deal with AAC  audio, or whatever. In this post, I’d like to document a easiest way to convert  AAC 5.1 to AC3 5.1, in the near future, if I have enough spare time, I’d like  to talk more about how to convert AC3 to AAC, that may be in my another post.

To convert AAC 5.1 to AC3 5.1, you just need Pavtube Video Converter only.  This program is capable of reading a wide range of video and audio formats,  including videos from DVs or camcorders (JVC, Panasonic, Cannon, Sony, etc.),  TiVo (*.tivo), DVDs (*.vob), Blu-ray (*.m2ts,), YouTube (*.flv, *.f4v), and  many other videos in common media formats, like mp4, avi, mkv, ts, tp, evo,  aac,dts and so on. The detailed process is as below:
