Audio Titlesets:

Since version 0.98 you may create 'Audio only' titlesets. Select 'Audio Titleset' from the 'Insert' menu and place the crosshair cursor on the main menu where you want to have the start button. In the following dialog you can select MP2/AC3 files, edit artist/album/title texts and select background images. If you stick accurately to the 'usual' filename pattern:
File name = 'artist - album - track -' with xxx = MP2 or MPA or AC3 (or WAV with MuxMan),
the strings for artist/album/title can be assumed from the filename. The track number may be removed or added as part of the title. If the option 'Use file name pattern' is switched off, or GfD cannot interpret the filename, the whole filename is used as title name. In this case you may preset the artist and album strings BEFORE you add the titles or edit them afterwards (either line by line or with the 'Set for all' option). Background pictures can be used in the usual formats (bmp, gif, jpg, png). The audio files must be already DVD conformal (48 kHz) and within one Audio titleset uniformly (either AC3 or MP2 - using MuxMan also WAV with 48 or 96 kHz; same number of channels...). Within one Audio titleset you can be insert a title only once.  Example:AudioTS1.png

The title sequence corresponds to that in which the titles were added, you may change it however with the up/down arrow buttons. If you prefer a more 'random' order, you can click on the 'Rnd' button, which 'sorts' the titles randomly. The layout can be individually set per audio Titleset. A click on 'Layout' opens a dialog, where the colors, positions and character fonts for the artist/album/title texts can be adjusted.  You can save your favorite layout in the Def. Settings tab "AudioTS".  The 'Audio titleset name' is used as button text for the main menu.
The audio files are automatically checked when you insert them, the info is shown in the last column (scroll right, or smaller the other columns). If a file has the wrong (or not interpretable) properties, the 'note' turns red:

Remark: MuxMan is very strict concerning the standards. Therefore all properties of the audio files within one Audio titleset must be the same: bitrate, number of channels (no mix of mono/stereo/joint stereo files)... This is currently not checked by GfD, you have to take care for yourself.

This infos are not stored. If you reload the dialog, the info column is empty, but you can reread it with the 'Info' button (just below the Layout button)

Create Audiotitleset with Chapters/Titles:
For dvdauthor as authoring engine you may select to create the audiofiles as either own titles or chapters. Using 'Titles', the timecode is reset after each audiofile. Using 'Chapters' the audiofiles are connected and the audio titleset has a continuous timecode (you can nevertheless access each title individually from a menu). As in the official standard only 99 titles are allowed for a DVD (although many players have no problems with more than 100), I would recommend to use 'Chapters'. For MuxMan only the 'Chapters' mode is implemented.
Edit Pre/Post Command:
Starts the VM-command editor. There you may change the pre and post commands for the audio titleset (only for the whole, NOT for each title individually)

Menu for start of individual titles
For menu creation load the appropriate titleset menu and drag & drop the individual titles (like chapters) on the background (or use the 'Grid menu layout' function). To achieve 'meaningful' buttons, select text buttons in the Def. Settings, set the button defaults to no text in  'default text for chapter buttons' and mark 'Add Time/Title' (if required also number).

Technically GfD produces a png file (bmp for MuxMan) with the background picture and the texts for artist/album/title.  This png file is encoded with png2yuv/mpegenc to a single frame m2v file, which is finally multiplexed with the audio file to the MPG file using mplex. As mplex doesn't add navigation packs (except the first one) for 'single frame' MPEGs with a (longer) audio file, insnav (a small commandline program from C. Patel) is used to add these additional navigation packs as a postprocessing step. Using MuxMan this long way round isn't necessary, as MuxMan creates the vob files directly from the BMP images and the audiofile during the DVD creation process. This is much faster and uses less recources, therefore I highly recommend using MuxMan for pure audio DVDs.

- 96 titles per Audio titleset

- Not every DVD player may work with this DVD type (single frame mpeg with long audio file) correctly
