    I have some aiff files that are too big for a cd-r but would fit on a
    dvd-r. They're standard cd audio format: 44.1Khz 16-bit pcm. Can I
    create either a DVD-Audio or audio-only DVD-Video image with this data,
    _without_ resampling? What software would I need to do this? I own
    Toast 6, iLife 5 and ffmpegx, but I'm not clear that any of these tools
    can do this. I'm happy to build and use opensource unix/linux apps if
    that's a viable alternative. I'm also willing to upgrade to the latest
    Toast and/or iLife, if that would help. I'm probably not willing to
    spend a lot of money on professional software, though, at least not
    right now.

    If resampling is a requirement (eg if for some reason dvd audio has to
    be 48K rather than 44.1), what osx utility does the best job?

    Following up my own post here --

    Thus turns out to be very easy, and I apologize for having posted the
    question before I did enough research. For anyone else who might be

    1. Download the sources from

    2. Build the sources (unzip, cd to the src directory, type 'make')

    3. Run the following command in Terminal:

    dvda-author -o MyDVD -g mydata.wav

    where MyDVD is the name of a new directory where the data will be
    written, and mydata.wav is the name of the audio file. You can include
    multiple -g values.

    A minute later, the program will have created the new directory with an
    empty VIDEO_TS and suitably formatted data in the AUDIO_TS. It's a very
    fast process. This directory can now be burned to dvd-r as a udf image
    with Toast, resulting in a properly authored DVD-Audio disc that should
    play in any DVD-Audio player (though I can't verify this until my player
    arrives next week).

    No resampling is necessary: the DVD-Audio standard includes support for
    44.1/16 data and dvda-author handles it without issue.

    The only small downside with dvda-author is that it only accepts wav
    (and flac), whereas my files are aiff. But aiff->wav is a quick
    lossless conversion I can do easily with Quicktime Pro.
