Audio Preferences
Audio Preferences: General
Create Overview after recording
To allow you to view new recordings of audio files in the Arrange window, Logic has to
create an overview. Before it can do this, the whole audio file has to be read, which can
be time-consuming, depending on the amount of data involved. If you want to
continue working in the Arrange window without the waveform display, you can
switch off the creation of the overview after the recording. If necessary, the menu
option “Update File Information” in the Audio window will recognize that the overview
is missing, and create it later.
Audio engine overload message
If switched off, the playback will simply stop in an overload situation instead of
displaying an alert box.
Sample accurate automation
As the name implies Sample accurate automation is the most precise type of
automation. However, it requires more overall system performance. Therefore Logic
offers three options:
• Off: needs less system performance and might be required for older songs (pre
version 5 songs);
• Volume, Pan, Sends: the most important parameters are automated with sample
accuracy;
• Volume, Pan, Sends, Plug In Parameters: all of these parameters are automated with
sample accuracy. Please note: not all Audio Unit plug-ins can be automated in this
way.
Recording File Type
Lets you the determine the file type of recorded audio files. The options are:
• SDII = SoundDesigner II
• AIFF = Audio Interchange File Format (Default)
• WAVE = Most common Audio Format on Windows PCs
Crossfade Time
Determines a global crossfade time for all crossfade operations in the Arrange window.
Crossfade Curve
Determines a global crossfade curve type for all crossfade operations in the Arrange
window.
Audio Preferences: Drivers
The Audio Driver preferences are covered in the Audio Driver chapter (see “Audio
Drivers” on page 271).
