WAVELAB Preparing a Basic Audio CD 17 – 361 Checking the total length of the CD The total length of the CD is displayed at the bottom of the Basic Audio CD window. Playing files in the track list There are several ways to play back a file in a Basic Audio CD. •Click with the right mouse button in the track column for an item (any type of marker will work), and select from the menu items. The items should be self explanatory. Please note that clicking on a track end marker allows you to play a transition between two tracks with a short pre-roll time. •Double click on a track name, or select it and press [Enter] or [F8]. This plays the entire list, from that point and on, including pauses. Hit [F7] or [0] on the numeric key pad to stop. •Double click on a Length field. This plays the section between this and the next marker. •You can drag and drop a track title onto the Play button on the Transport bar. This is just the same as double clicking on the track name. Please note: • What you hear during playback is identical to the way the audio will be played back from the actual CD, that is, all pauses and other adjustments are taken into account (this includes the Advanced Settings unless otherwise stated). • During playback, a progress bar appears at the bottom of the window. There will be no play cursor in the actual Wave window. • During playback, you can toggle between track-local time and CD global time by clicking on the time counters in the bottom right corner of the window. • Changes to markers are not taken into account during playback (you need to stop playback and start again). • If you have material in the list that does not have the correct sample rate (44.1kHz), this can still be played back. However, when you activate playback, all files will play back at the same rate. The inherent rate of the selected file (the one that plays first) will be used for all files. Playing back via the Master Section To make the audio play back through the Master Section, activate the cor- responding option in the Preferences–CD Burning tab, and open the Master window. The default setting for this is off.
WAVELAB 17 – 362 Preparing a Basic Audio CD Creating a disc image There might be situations where you want to “freeze” an entire Basic Au- dio CD, without actually burning a CD. This is done with the “Save as CD image” command. 1.Set up the track list so that it is exactly as you want it. 2.Select “Save as CD image” from the CD menu. 3.Find a directory for the files (we recommend that you create a new direc- tory, since the “image” is made up of three different files), and type in a name. 4.Click OK. Now, the following is created in that folder: • A Basic Audio CD file, with the specified name. This is the file you will want to open the next time you want to access this “CD image”. • A single wave file, containing all the tracks, with markers inserted at all the correct positions. • A marker file with the same name (it is this file that actually contains the markers). • A peak file for the wave file.
WAVELAB Preparing a Basic Audio CD 17 – 363 Exporting audio files from a track list There are situations where you might want to save the items in a Basic Audio CD as audio files on your hard disk (e.g. for archiving or when you use the Basic Audio CD as a general play list for preparations of files for other purposes). You can either save the tracks as separate files or as one single audio file. As separate files To save the files in a Basic Audio CD as separate files, proceed as follows: 1.Set up the track list so that it is exactly as you want it. 2.Select “Save each track as a separate audio file” from the CD menu. The “Save each track as a separate audio file” dialog. 3.Find a destination folder for the files. 4.Click the large audio properties button to decide the output format for the files. This opens the Audio File Format dialog, in which you can select the desired format and make settings for it. Click the question mark icon in the dialog for details. 5.Fill out the other options in the dialog. Click the question mark icon in the dialog for details. 6.Click OK. Now, the tracks in the list are saved as separate files, in the specified folder.
WAVELAB 17 – 364 Preparing a Basic Audio CD As one file To turn the entire Basic Audio CD into one long file, proceed as follows: 1.Set up the track list so that it is exactly as you want it. 2.Select “Join all tracks into one virtual file” from the CD menu. 3.Fill out the other options in the dialog. Click the question mark icon in the dialog for details. 4.Click OK. The new file appears in a Wave window. 5.Save the file, like any other wave file. Preparations done! If you have set up a Basic Audio CD to your liking, the next step is of course the actual CD burning process. This is described in the chapter “Burning an audio CD” on page 571.
WAVELAB 18 – 366 About the DVD-Audio format Background information With its unique ability to create and burn DVD-Audio compatible discs, WaveLab is a major step forward in bringing this versatile audio format to a wider consumer market. DVD-Audio offers high resolution and multi-channel audio plus extra con- tent such as still images and text. DVD-Audio is likely to become the stan- dard media for audio in the future. The structure of a DVD-Audio project About albums, groups and tracks To understand DVD-Audio projects, let’s start with a look at the structure hierarchy: •A single sided DVD-Audio disc can contain one album. •An album can contain up to 9 groups. In WaveLab, a group corresponds to a Montage, but it can also be looked upon as a playlist for tracks – see below for further details. •Each group can contain up to 99 tracks. Tracks are defined by DVD track start and end markers in the Montage. A given track may be referenced by more than one group. One group can consist of a complete list of songs played in a certain order. Another group can be a separate playlist of the slow, acoustic numbers from the song list, while a third group might be a playlist of the up tempo tracks, all taken from the same collection of material. A group can of course also contain alternative mixes of the “original” tracks or just different tracks altogether.
WAVELAB About the DVD-Audio format 18 – 367 What can a DVD-Audio project contain? The DVD-A specification allows for three main content groups: •Audio content DVD-Audio allows for audio files in a variety of channel configurations and resolutions, e.g. high resolution stereo and multichannel (surround) formats with up to 6 channels. Each group (i.e. Montage) can have different channel configurations and audio resolution set- tings. See “Audio format considerations” on page 369 for details regarding audio formats. •Value-added content (optional) Real time text and still pictures can be added to the DVD-A project. A compatible DVD- player connected to a video display can for example display real time text as a song is play- ing, as well as displaying a slideshow of pictures. There are special tracks in the Montage where you can add pictures and text directly on the time line – see “Using DVD-A picture and text tracks” on page 546. •DVD-V content (optional) This can be video and audio material authored to the DVD-V format. You can add such con- tent to a DVD-A project in WaveLab, but it has to be authored in another application. DVD- A discs that contain video content are referred to as “hybrid” discs. To view movie contents you need to play back the DVD-A either in a universal DVD player, or a standard DVD-V player (see “Types of DVD players” on page 370). In addition to the above, a DVD-ROM sector can be added to the disc, containing any type of data files. See “Creating a DVD-Audio compatible disc” on page 589. An example DVD-Audio project could contain the following: •A group with 5.1 surround mixes of various songs, including real time text and still pictures. •A group with high resolution (up to 24-bit/192 kHz) stereo mixes of the same songs. •A group with a different playlist of some of the same songs, perhaps de- fined by style and/or tempo. •Video clips (interviews, promo videos, etc.).
WAVELAB 18 – 368 About the DVD-Audio format Data structure of a DVD-Audio disc The contents of a DVD-Audio project are stored in a folder named AUDIO_TS (Audio Title Set), which includes all audio, still picture, text and visual menu data. The AUDIO_TS contents are created when you render a DVD-Audio project, and are data files in various special formats readable by the DVD-A player. These cannot be opened or edited in WaveLab. It is also possible to add a VIDEO_TS folder (authored in another applica- tion) containing video content which can be viewed in standard video DVD players and in universal DVD players (see “Types of DVD players” on page 370). Audio formats For Montages that are to be included in a DVD-Audio project you must use a PCM (uncompressed) audio format. Apart from this, a DVD-Audio project can contain audio in a wide variety of resolutions. Supported sample rates and bit-depths are: You can use other bit resolutions for audio files in a Montage, but they will be stored on the DVD-A disc as either 16 or 24 bit audio samples, re- gardless of the original resolution. The bit resolution of the DVD is speci- fied in the DVD-Audio options dialog – see “Using DVD-A picture and text tracks” on page 546. Sample Rates Bit-depths 48 / 96 / 192 kHz 44.1/ 88.2 / 176.4 kHz16 / 24
WAVELAB About the DVD-Audio format 18 – 369 Audio format considerations There are two main considerations when planning a DVD-Audio project: •The total size of the album. A single album cannot contain more data than 4.7 GB (using a standard single layer DVD). In the table below you can see the maximum recording time on a single sided, single layer DVD for various formats. •The maximum allowable data rate for a group. The data rate is the data “bandwidth” necessary to reproduce a given number of channels at a certain bit resolution and sample frequency. The DVD-Audio specification allows for a maximum data rate of 9.6 Mbps (Mega bits per second) when using an uncompressed PCM audio format. For example, a group containing a 24-bit / 96 kHz 5.1 surround Mon- tage would exceed this 9.6 Mbps limit, thus it would not be possible to use this group in a DVD-Audio project. To keep a DVD-Audio project within the allowable data rate limit, use the table below as a guide: • If a group’s number of channels and sample rate exceed the 9.6 Mbps data rate a warning will appear when using the Check function (see “Using the Check function” on page 568). Number of channels Bit resolution/sample rate Max recording time 6 16-bit / 96 kHz or 24-bit / 48 kHz 64 minutes 2 24-bit / 192 kHz 64 minutes 2 24-bit / 96 kHz 129 minutes 2 16-bit / 44.1 kHz 421 minutes Number of channels Maximum bit resolution/sample rate 6 Up to 16-bit / 96 kHz or 24-bit / 48 kHz 4 Up to 24-bit / 96 kHz 2 Up to 24-bit / 192 kHz
WAVELAB 18 – 370 About the DVD-Audio format Types of DVD players There are three basic types of DVD players: •DVD-Audio player. This could either be an audio-only player (AOP), or a player capable of displaying visual menus, text and still images. •DVD-Video player. This is referred to as a “V-Player” (Video Player), and is capable only of playing back video contents contained in the VIDEO_TS folder. •Universal DVD-Audio/Video player. This is capable of playing back DVD-Audio data, displaying menus, text and still images. It can also play “hybrid” DVDs with both DVD-A and video content (contained in a VIDEO_TS folder), as well as standard video DVDs. About DVD disc formats Virtually all common types of recordable DVD formats can be used for burning DVD-Audio compatible discs. Supported formats are as follows: Format Description DVD+R Non-rewritable with a recording capacity of 4.7 GB. DVD-R Non-rewritable with a recording capacity of 4.7 GB and 9.4 GB. DVD+RW Rewritable with a recording capacity of 4.7 GB. DVD-RW Rewritable with a recording capacity of 4.7 GB. DVD-RAM Is rewritable and available in capacities up to 9.4 GB.
