20 <title>Table of Contents </title>
22 A Table of Contents is a description of the data stored on a medium.
23 In the case of audio Cds, the TOC comes in the form of PQ data which
24 is intermingled with the audio data whaen the CD is burnt. Because PQ
25 data isn't part of 'normal' audio file formats such as wav or aiff,
26 this information must be stored in a separate file on your computer (a
27 CUE or TOC file) ready for use by your CD burning software which will
32 At the moment, Ardour can export TOC and CUE files containing the
33 red-book related fields Track, Index, ISRC, SCMS and Preemphasis. The
34 CD-TEXT fields TITLE, COMPOSER, PERFORMER and disc title are also
39 Range markers in Ardour can be 'promoted' to become CD tracks in the
40 locations window. Marks (point markers) can be promoted to be CD
41 Indexes in the same window. All TOC/CUE export operations hinge on
46 Assuming you have several songs on your timeline laid out so that
47 their spacing and level is 'correct' as you hear it, you should then
48 set ranges that represent the start and end points of each track,
49 These will become the start and end points on your CD. The start times
50 are all rounded down to the previous CD frame (Of which there are
51 75/second) on export, so if you want to hear the exact point that your
52 CD player will start from, select 'CD frames' as your snap setting
53 while you do this. If you want track indexes (nobody does, but they're
54 there), set a location marker for each desired index.
58 The locations dialog is useful here, as you can just 'go' to a point
59 to audition the exact position of a marker/range.
64 <title> Pregap </title>
70 A 'normal' redbook CD should have a blank (digital black) space of 2
71 seconds before the first modulation called the pregap. Ideally, your
72 first song will have been placed at 2 seconds when you began, but you
73 can always drag the whole collection of songs to the right position
74 fairly easily at this point.
78 Also, note that this 2 second rule can be fun to break. You can make
79 the pregap as long as you like.. even hide whole songs in there. The
80 player will still play track one when the disc is inserted. Only those
81 listeners with the urge to rewind beyond the beginning will find your
82 hidden song/dog bark. Also keep in mind that there is a pregap for
83 each song. It starts where the previous song ends. In other words, if
84 you leave a gap in the ranges between songs 2 & 3, that gap will
85 only play for those listening through the entire CD. Anyone skipping
86 directly to 3 will miss your secret 'long' intro.
90 After setting a non-overlapping range for each track (overlapping CD
91 tracks are removed on export, from left to right, as are indexes that
92 aren't inside a track), open the locations window and make your ranges
93 into track markers by clicking the CD button. Fill in whatever
94 information you feel is necessary in the boxes below. Unused fields
95 will be ignored as far as the exported TOC/CUE file is concerned.
99 CD-TEXT track titles are taken from the range's name. The CD-TEXT
100 title of the CD is taken from the session name (i should have told you
106 Pre-emphasis is there for those strange types that use it (they also
107 use track indexes). You almost certainly don't want pre-emphasis. A
108 valid ISRC is all capitals, 12 characters.

114 <title> Cue Files </title>
116 Cue files have no notion of 'the end'. Its a drag. They think the end
117 of the file is the end of the last track. If you want to use CUE
118 files, you have to make sure that the session end marker is snapped to
119 CD frames (before you export, of course), or else use the -pad option
124 <section id="export-the-session">
125 <title> Export The Session </title>
127 Now export the session to a file (16bit 44.1kHz for CD), selecting
128 your preferred cuefile type (TOC or CUE). The TOC/CUE file is written
129 to the same directory as your audio file, and has the same name, only
130 with '.toc' or '.cue' appended. Usually you will only be selecting the
131 two master outputs to export, with output 1 always being 'left'. The
132 export is post fader and panner. Don't assume that the sound will be
133 identical after you have truncated/dithered to 16 bits. It can be
134 worthwhile to experiment with different dither settings when making

145 to correct a problem, make your changes, then use the 'export toc file
146 only' option. If you have to change the session end marker, you'll
147 have to re-export your audio file.
154 cdrdao write /home/britney/globalsmash.wav.toc
161 If you don't make any CD Track ranges and export a TOC/CUE file, the
162 entire session is treated as one track with no pregap. Indexes, if
163 present, will be honoured.

170 Why no DDP? ( http://www.dcainc.com/products/ddp/ )
174 A: DCA have been kind enough to get in touch. Hopefully they will
175 allow a GPL implementaton soon.
179 <section id="catalog-numbers">
180 <title>What about catalog numbers for the CD?</title>
182 A: coming eventually.. we need a tab for session-wide variables like
183 these. where to put it? in the export dialog or the options menu?
