    I'm looking for ways to author 24/96 audio files in such a way that I can play them on any DVD player.

    From what I could find out, that can be achieved authoring DVD video discs. The matter seems to not too clear on some googling I did, as it mixes with SACD or DVD-Audio, which need specifically capable players.

    One program I am trying now is Audio DVD Creator, but I'm having some glitches when playing on my BD player. It happens on one file, the player stops in the middle, but I didn't listen to the whole record, where I put about 30 files or so. Already re-authored and looked at the wav file in SoundForge, but the file seems fine and the problem persists, always in the same place.

    As I am not familiar with this type of programs, I don't know what or how to test it.

    What other programs do that same processing?

    24/96 is not part of the DVD Video standard*. Very few DVD players support DVD Audio. Some Oppo models will.

    * Audio within the DVD Video standard is limited to 16/48 PCM stereo.

    No, I do not want DVD-audio discs or SACD discs, as very few players play them.

    It has to be audio authored in the video tracks with high resolution.

    What part of edDV's exactly correct answer did you not understand ?

    24/96 is not part of the DVD Video standard*.
    In other words, you can NOT
    author 24/96 audio files in such a way that I can play them on any DVD player
    If they could be authored into dvd video tracks at those specs, they would not have made DVD-A disc's and special players to play them.

    * Audio within the DVD Video standard is limited to 16/48 PCM stereo.
    The only way to accomplish this is to resample them to what is within the DVD SPECS for audio!
    SO they will no longer be 24/96 high resolution audio.

    DVD-Video allows LPCM streams having 1 to 8 channels of 16, 20, or 24 bits per sample, 48K or 96K samples per second. However, due to the bitrate limitation of 6144Kbps not all combinations are possible.

    Hmm, I recall a discussion back when DVD-Audio players came out. I knew that DVD-Video could have up to 8 PCM tracks but players only are required to play two (or a single stereo pair) at a time.

    I've been looking for evidence 24bit/96KHz files can be played and a proven authoring method. So far I found this
    http://forum.ecoustics.com/bbs/messages/1/584337.html

    That guy said the PCM audio must be placed in an MPeg wrapper.

    The Linn Records site was no help.
    http://www.linnrecords.com/linn-help-download-Burning-downloaded-music-onto-DVD.aspx

    So the questions remain.

    How would one author 24bit/96KHz audio to a VIDEO_TS folder?

    Will all players play these files?

    If the files will play, will the PCM be downsampled to 16bit/48KHz over S/PDIF?

    Correct. Sometimes the "spec makers" are quite stupid alright.


    So the questions remain.

    1. How would one author 24bit/96KHz audio to a VIDEO_TS folder?

    2. Will all players play these files?

    3. If the files will play, will the PCM be downsampled to 16bit/48KHz over S/PDIF?
    1. mplex + dvdauthor ? Muxman ?? ( <-- creation of mpucoder, BTW )
    DVD-lab PRO ???

    2. That's another story, sadly.

    3. Probably. But at least my old SAP does have 6 analog audio outputs.

    Stick it in with a BMP or short M2V and author using Muxman.

    Yes.
    3. If the files will play, will the PCM be downsampled to 16bit/48KHz over S/PDIF?
    Maybe, maybe not.

    [3.6.2] Audio details of DVD-Video
    The following details are for audio tracks in DVD-Video. Some DVD manufacturers such as Pioneer are developing audio-only players using the DVD-Video format. Some DVD-Video discs contain mostly audio with only still pictures.



    A DVD-Video disc can have up to 8 audio tracks (streams) associated with each video track (or each video angle). Each audio track can be in one of three formats:
    • Dolby Digital (AC-3): 1 to 5.1 channels
    • MPEG-2 audio: 1 to 5.1 or 7.1 channels
    • PCM: 1 to 8 channels.
    Two additional optional formats are provided: DTS and SDDS. Both require the appropriate decoders and are not supported by all players.
    The ".1" refers to a low-frequency effects (LFE) channel that connects to a subwoofer. This channel carries an emphasized bass audio signal.
    Linear PCM is uncompressed (lossless) digital audio, the same format used on CDs and most studio masters. It can be sampled at 48 or 96 kHz with 16, 20, or 24 bits/sample. (Audio CD is limited to 44.1 kHz at 16 bits.) There can be from 1 to 8 channels. The maximum bit rate is 6.144 Mbps, which limits sample rates and bit sizes when there are 5 or more channels. It's generally felt that the 120 dB dynamic range of 20 bits combined with a frequency response of around 22,000 Hz from 48 kHz sampling is adequate for high-fidelity sound reproduction. However, additional bits and higher sampling rates are useful in audiophile applications, studio work, noise shaping, advanced digital processing, and three-dimensional sound field reproduction. DVD players are required to support all the variations of LPCM, but many subsample 96 kHz down to 48 kHz, and some may not use all 20 or 24 bits. The signal provided on the digital output for external digital-to-analog converters may be limited to less than 96 kHz and less than 24 bits.

    There are some directions that confirm what I want is available here:

    http://24bit.turtleside.com/

    By the time I read that, I already installed and used Audio DVD Creator.

    http://www.audio-dvd-creator.com/

    I don't quite understand how it is done yet, but it seems to record the 24/96 wav audio files as video files.

    Nah, it's just adding a still image to the audio to create a DVD-Video file. It's the same thing I mentioned before.

    I did such 24/96 things with DVDLab's Audio Title option. Individual still picture for each chapter (since version 2.xx), usual menus and additional video titles if necessary.

    OK. I did try DVDLab Pro 2.3 and it does seem to allow that.

    But it seems that I have to get a new still frame for every music. Is that so?

    edDV was 100% incorrect.

    The reason for the DVD-A standard was to introduce DRM, and to enable 6-channels of 24/96 using lossless compression. (The datarate for 6-channel 24/96 without lossless compression is too high for DVD video). If you only want stereo 24/96, standard DVD video is fine.

    Cheers,
    David.
