    Hello audio guru's

    I realize that AAC audio is fairly new, so I don't expect much solutions, but..

    After searching through the guides for any WAV -to- AAC how to's, I couldn't find any in the
    listings. Then, at the bottom where it lists (via links) I saw a wav-to-aac, but that is a doom9
    guide and it listed tools that are .NET or not so compatible to my old and aging windows 98 system.

    So, I'm basically looking for some pointers on WAV -to- AAC (perferably with command-line tools)
    from anyone who have done some work in that area already. Basically its for uploading some
    ready-made (h264 via .mp4 videos) onto youtube, obviously with good quality.

    I am using the x264 cli command line tool to encode the videos to h264, but there is no audio.
    So obviously I have to do the audio part separately and then MUX the two together. I'm not
    sure of the steps, but I'm sure I'll figure it out along the way. I'm just not sure of the way(s)
    to WAV it to AAC, etc.

    Thank you,

    The free Nero aac encoders are considered to be the "best".

    http://www.nero.com/eng/nero-aac-codec.html

    Syntax is something like:

    neroAacEnc.exe -br 96000 -if input.wav -of output.m4a (or aac)

    Thank you for the quick response. I will check it out and research it for Windows 98 support,
    and if goes well, I'll report back my success

    Well, looks like we have a winner It worked like a charm. Thanks pal.. though I managed using
    the param script you provided as a bases (below) to encode a demo audio:

    --> neroAacEnc.exe -br 96000 -if input.wav -of output.m4a (or aac)

    ..semed to do ok, that is, it worked.., but not without resorting to learning how to MUX the
    [audio|video] together for a final MP4 (h264) video. I had to jump through lots of hoops in
    search of a how to, which I could not find, alas, I did, in the end, though I'll spare you the
    long story. Anyway. I was doing this for several of my analog cabletv captures of the star wars
    freekin saga of this past week, and I wanted to post some clips of it. Thanks for your help.

    Right now, I'm not sure of what is an acceptable encoding strategy for AAC and MP4 videos
    for YT streaming purposes.

    Yes! Why do you ask ??

    Yeah, I can use Yamb. You know it was a success in another post elsewhere. But my main
    drive for this is for my on-going tool developments with command line apps. One idea I have
    is to conjure up a one-click, dran'n'encode tool, where I just drag a script or project or some
    file into it (or whatever the tool) and away it goes. Nothing fancy or looser configure-able.

    Just curious. Mp4box has a lot of parameters (well, not compared to ffmpeg). There's a modded version called NicMp4Box that always resulted in perfect iPod compatible mp4 files on the stuff I tried it with.

    Sorry for not responding back, suppafresh, I've been very busy with my personal time
    and also reviewing the Star Wars trilogy's they were broadcasting (for the ivtc-able applications)
    over the past two weeks. They were using the excuse just so they (SpikeTV) could broadcast
    the Episode III movie first, so they made a big deal over it all, though 4:3 fullscreen. Anyway.

    Just curious. Mp4box has a lot of parameters (well, not compared to ffmpeg). There's a modded version called NicMp4Box that always resulted in perfect iPod compatible mp4 files on the stuff I tried it with.
    Yea, I did D/L the NicMp4Box version, too. But I haven't played with it just yet. So far, I've been
    working inside x264 cli and then reviewing applications with MP4box, though I did have a problem
    with it (param string setup) at first -- it was tricky.

    But, if mp4box (or its 'nic' alternate) can be useful in my h264/mp4 endeavors, then that is the
    way I will go with this new video format.

    I am actually doing many things at the moment. Multi-tasking is a chore for sure

    Anyway. This is all prob for another topic, however
