    Okay, it's the second time now i'm encountering this problem.

    After i've encoded an .avi source file with handbrake, and i use the preset Apple TV 3 or just standard avi to mp4 I'm getting this problem with the audio.

    Once the audio was very slow and sounded really low, like an old drunk guy was talking, the other time it was too fast, and everything sounded like in a cartoon ...

    What am i doing wrong, i'm not messing with any audio presets in handbrake ...

    Handbrake version: Version 0.9.9 x86_64 (2013051800)
    Mac Os Mavericks

    thanks

    If it can help, i've noticed my movie time of the converted file is double as long as the original. I use the setting "same framerate as source"

    Would have to see an activity log from Handbrake to be able to tell. Hb keep a log of all encodes.

    https://trac.handbrake.fr/wiki/ActivityLogByPlatform

    copy and paste it to a pastebin site (pastebin.com is a decent one) and post the link to it here.

    No other way to tell.

    My guess: some kind of mismatch between what HB thinks is the audio sampling rate and what the sampling rate actually is.

    Well ... this tells me it is a defective source

    Code:
    [mp3 @ 0x102392a00] Header missing
    The audio track is missing the header info, which HB wants.

    HB uses libav (a branch of ffmpeg) to decode these types of files. This one you have is malformed.

    When you download torrents, you get what you get from whoever you got it from. Bogus source.

    ----------

    One thing you could try is to download a nightly of hb and give it another try. The nightlies us a newer rev of libav and may be able to grok the audio better but I wouldn't count on it.

    Why do you spend your time with those avi movies anyway?
    Most material worth watching (BDrips) is in mkv to begin with.
