Audio Interleave

In the Audio panels of the Project and Export Movie Settings dialog boxes, you can specify the amount of audio interleave in the Interleave pull-down menu (Figure 18.32). In the Capture Settings dialog box, click the Advanced Settings button to specify interleave (Figure 18.33). Audio interleave determines how often audio information is loaded into RAM and inserted, or interleaved, among frames of video. Previous versions of Premiere referred to audio interleave as “audio blocks,” because blocks of audio are interleaved with blocks of video. Usually, an interleave value of 1 second results in smooth playback. If the audio falters during playback, however, you should adjust the interleave value. A low value needs less RAM but requires the computer to process audio more often. A large value results in larger audio blocks that are processed less often but require more RAM.

Figure 18.32. Specify the audio interleave value in the Audio panel of the Project or Export Movie Settings dialog box. In most cases, 1 second works fine.
