Scrambled Audio

    CloneDVD mobile does a beautiful job of converting 16:9 (widescreen) video into a 4:3 AVI file I use on my Arcos AV320. The audio on the other hand, is unusable. It's all scrambled and unintelligable. Since everything is kind of "behind the scenes", I don't know what CloneDVD mobile is doing with the audio. Any ideas?

    Thanks

    The audio is complete gibberish, or just out of sync? Do the AVIs play fine on your PC?

    The scrambled audio is in sync. The best way to describe it is kind of like someone trying to gargle and talk at the same time. The AVI file plays great on the PC and on a Divx capable DVD player. Maybe it's something as simple as variable bit rate verses constant bit rate but I have no way of knowing what CloneDVD mobile is doing in the background or even what MP3 encoder it is using.

    The relevant section of the DEVICES.INI file for your device is as follows:

    [AV320]
    Manufacturer=Archos
    Res1=320x240
    ResAna1=320x180
    ResExpand1=320x240
    VCodec=mpeg4
    VTag=DIVX
    Acodec=mp3
    ARate=44100
    ABRate=128
    MVolume=10
    Format=avi -noodml
    FileType=avi
    Quality=23
    useMencoder=1
    SubTitle=1
    lavcopts=vcodec=mpeg4:acodec=mp3
    MaxVBitrate=2000


    This shows that it's using a 44.1KHz 128Kb/s audio stream, and since there's nothing to suggest that it's VBR, I would assume it's CBR - this is supported by examination of DivX files I've already generated.

    If you split out the MP3 from the AVI using an appropriate utility, does it play by itself on your Archos?

    Do you have a program in mind that I could use to strip the MP3 audio stream from the AVI file?

    Funny... I thought it would take 30 seconds to find a little freeware app to spit out the mp3... but I'm surprised to find that it's not that easy! Have spent half an hour looking for you, no joy so far! lol

    Anybody else?
