In the majority of cases, users want the in- and the out- crossfade components to be of equal duration and to change together. Marking the Preserve Timing checkbox while working in Centered mode effectively locks the fades together. Dragging with the Crossfade tool then changes the durations of both fade components equally.

Another useful crossfade technique is the rolling edit. In a rolling edit, the Playlist Events do not move, and the fade durations and edit point maintain their relative relationships, while the entire crossfade slides as a time window over the Events. You can accomplish a rolling edit in either Overlap or Centered mode by first engaging Preserve Timing, and then dragging with the Trim tool.

For more accuracy in adjusting fade durations, the Nudge In and Out buttons enable you to change either fade component in increments of whatever duration you enter in the Nudge Time field, which is located immediately below the buttons. By default, the Nudge buttons perform quantized versions of the Move Event tool''s actions in Overlap mode and the Crossfade tool''s actions in Centered mode. Holding down the Option key causes the Nudge buttons to perform quantized versions of the Trim Event tool''s actions in either mode.

In the List View, you can enter fade durations as text by clicking in the I-XF-T (In Crossfade Time) or O-XF-T (Out Crossfade Time) column, and then directly editing the value. Entering durations directly offers the greatest precision.


The Red Book specification for CD-DA (standard audio CDs) defines a Pause marker. Though inserting a Pause in most disc-burning applications creates silence before the next track, the Red Book spec says that the Pause marker''s actual function is to trigger a CD player to show a countdown to the beginning of the next track. Often, this occurs in an area of silence between tracks; however, in some situations, such as a live-concert recording, it may be desirable to have the Pause countdown occur when audio, such as audience applause, is actually playing.

In Peak Pro 6''s Waveform View, you can treat a Pause marker and a gap of silence (that is, a negative overlap) independently. Create a negative overlap in Overlap mode by simply dragging an entire Event until it no longer overlaps the adjacent Event.

You can create a Pause by entering a value in the List View Pause column, or by using the Arrow (Select) tool to grab the handle of the Pause indicator (a yellow line) at the head of an Event and then dragging it to the left. A live time indicator next to the green area designating the Pause helps you set the duration correctly.


Peak Pro 6 adds substantial capabilities for editing metadata in audio files, but the Playlist also supports metadata commonly associated with audio CDs. ISRC (International Standard Recording Code) values are used to uniquely identify each track and are used by some music services to retrieve information about a CD. Although you can enter ISRC values directly in List View by clicking in an Event''s ISRC column, it is common for successive tracks to have sequential ISRC codes.

To ease the need for repetitive entry, you can enter ISRC values along with track-specific CD-TEXT data. Clicking in the CD-TEXT checkbox in List View opens a CD-TEXT dialog box in which you can enter CD-TEXT information specific to the selected track (see Fig. A). At the bottom of the dialog box is a field for the ISRC value, with a Copy From Previous button adjacent to it. When you click on it, this button will import the most recent ISRC value defined. Duplicate ISRC values are not allowed, so be sure to change any value you copy to give each Event a unique ISRC value. Click on the Audio Compact Disc Info button to open a dialog box for entering data that applies to the entire disc.
