Chapter 6 Work with projects 150
Match a file’s sample rate with the project sample rate
m Use the Project Audio Browser’s Copy/Convert File(s) command (which is also available by
Control-clicking the Project Audio Browser or using the corresponding key command), then
replace the file in the project.
Logic Pro performs a real-time, native sample rate conversion. Any sample rate available in Logic
Pro (via Audio > Sample Rate) can be used for the conversion—even if your audio hardware
doesn’t support the selected sample rate.
The native software sample rate conversion function matches the sample rate of any audio
hardware, thereby allowing the playback of projects on virtually any audio system, even if
the hardware is—in sample rate terms—not compatible. Nothing is lost in the process. Any
internal processing and bouncing is always performed at the original sample rate, and at the
highest quality, even in cases where the hardware doesn’t support a particular sample rate.
This feature allows you to work on projects originally created on high-end audio systems, with
lower-end setups.
For example, imagine a project was created with audio hardware set to operate at 96 kHz.
Moving this project to another computer (for example, a notebook computer) that doesn’t
support the original project’s sample rate will result in the wrong playback speed. The native
real-time sample rate conversion function will counteract this effect, allowing correct playback of
the project on the portable computer, at any sample rate.
Note: Higher sample rates not only use up more disk space, but also require more processing.
