370 Chapter 14 Recording in Logic Express
When finished with your project, bounce it at the desired sample rate. As suggestions
for different situations:
 If the bounced file is destined for an audio CD (assuming you’re not sending it to an
external studio or application for mastering), there’s no need to go any higher than
44.1 kHz, as this is the standard CD sampling rate.
 If you work in the film or television industry, you will probably use the 48 kHz
sampling rate for audio.
 If recording classical or jazz groups (smaller ensembles), or archiving 75 year old
recordings, you may find some benefits to recording at 96 kHz or higher.
Playback of 96 kHz (or higher rate) audio files places a far greater throughput burden
on your system, and uses much more hard disk space. Recording at a 44.1 kHz sampling
rate and 24 bit depth is recommended for most situations.
Setting the Bit Depth
Logic Express defaults to 16 bit audio file recording. If you have suitable audio
hardware, 24 bit recordings offer a significant improvement in the available dynamic
range. 24 bit files use one and a half times the disk space of comparable 16 bit files.
If you require 24 bit recording:
1 Open the Audio preferences by doing one of the following:
 Choose Logic Express > Preferences > Audio (or use the Open Audio Preferences key
command).
 Click the Preferences button in the Arrange Toolbar, then choose the Audio
command.
2 Click the Devices tab, then click the Core Audio tab.
3 Turn on the 24 Bit Recording option.
