More Audio Track Bug Fix
Download build 1369Pre-release
A pre-release: newer than the current release, build 1315, and still settling in. Most people should use the current release.
Set the audio pitch algorithm to variable. This should reduce the audio demands, but still may not fix the current audio problem. With the new pitch setting, audio increases in pitch as playback speed increases. If this does not fix the problem, the next thing that will be tried will be to remove audio tracks from all angles during playback, apart from the focus angle.
