I hate to add further confusion to the bonfires, but the pregap length and silence have nothing to do with each other, per se. You can have 2 second pre-gaps with zero inter-track silence. Casualty: your CD player's time elapsed value will look strange around track transitions compared to a "normal" CD mastered with P subcode bits set appropriately. Most people seem accustomed to see the timecode "countdown" from -00:02 during two second "pause" gaps between tracks. Pre-gap is only silence if the P subcode flag says it is. I will give two examples of controlling silence values in a DAO table of contents listing: (This is in cdrdao syntax, which resembles "professional" formats) // Track 3 TRACK AUDIO NO COPY NO PRE_EMPHASIS TWO_CHANNEL_AUDIO FILE "track3.wav" // Track 4 TRACK AUDIO NO COPY NO PRE_EMPHASIS TWO_CHANNEL_AUDIO FILE "track3.wav" [ no silence ] If you want silence: TRACK AUDIO NO COPY NO PRE_EMPHASIS TWO_CHANNEL_AUDIO FILE "data.wav" // Track 4 TRACK AUDIO NO COPY NO PRE_EMPHASIS TWO_CHANNEL_AUDIO SILENCE 00:02:00 FILE "data.wav" If you want 2 seconds of silence with a 2 second "countdown" timer between the tracks, with index points defined every minute within the track: TRACK AUDIO NO COPY NO PRE_EMPHASIS TWO_CHANNEL_AUDIO FILE "track3.wav" // Track 4 TRACK AUDIO NO COPY NO PRE_EMPHASIS TWO_CHANNEL_AUDIO SILENCE 00:02:00 START FILE "track4.wav" INDEX 01:00:00 INDEX 02:00:00 INDEX 03:00:00 INDEX 04:00:00 (Yes, I know it's tempting to make a bunch of these to play some havoc with cd-player displays.) Incidentally, you can specify offset/length parametres to FILE to write out only a portion of one monolithic track file, as was asked before. Like so: FILE "track.wav" 00:04:00 10:00:00 (dump track.wav from the 300th through the 44,999th frames, inclusive) The pre-gap is demarcated by "INDEX 0" of the track. You may chase me 'round the Antares maelstrom, but I shall never give up Quality, =MB= -- A focus on Quality.
