    Let's see if tomorrow, 11-11, I get an extra discount on that Acasis.

  2. A simple solution but it is not true stereo, it's just duplicating the mono audio track.

    This can be done with FFMPEG :

    ffmpeg -i input.avi -c:v copy -ac 2 -acodec pcm_16le output.avi
    input.avi is the captured video file via Virtual Dub and output.avi the file created by FFMPEG with the mono audio track duplicated.

    Duplicating the mono track is not the same, even if you edit the new track a few milliseconds backwards. What was called simulated stereo.

    I am trusting I can feed a stereo track from the source in the device line input, which should be in sync with the video.

    Having a stereo line input I can even add an HDMI mini-DAC in the middle, as I did on my main system before buying the Pioneer receiver. HDMI in/out + RCA out. The sound was great, though stereo. For me stereo is enough, not such a great fan of 5.1.

    But all of this would be just a bet.

    Surprise surprise! The Acasis is "no longer available" for the 11/11 sale!

    Wanna bet that it will show again after the sale?

    Just didn't want to discount it.

    I think I discovered what might have happened: Acasis did release a new model with the same characteristics, including line audio in. Though you can select between two HDMI inputs and outputs.

    It seems better built, but it has no model name.
