22 Chapter 1 Setting Up Your System
Hard Disks
It’s also a good idea to have a large hard disk with plenty of available space to store
the media (audio and video) files you use with Soundtrack Pro. As you work with the
application, you’ll likely want to acquire a large collection of sounds to use in your
Soundtrack Pro projects. Hard disk performance is a critical aspect of your editing
system: the storage capacity and data rate of your disks must match or exceed the
requirements of the audio (and video) formats you are using.
If you store media files on an external hard disk, make sure the disk has a fast enough
seek time and a high enough sustained data transfer rate for use with video and audio
files. Consult the manufacturer’s specifications.
Dedicated Hard Disk
Every minute of stereo digital audio (recorded using a 44.1 kHz sample rate and 16-bit
depth) requires roughly 10 MB of hard disk space. If you plan to record large amounts
of audio in Soundtrack Pro, you may want to record to a hard disk dedicated to storage
for your Soundtrack Pro projects.
