Adding Pre-Recorded Media
Pre-recorded media plays an important role in modern audio
production. Combining existing audio loops and other files
provides a quick method for laying down song foundations.
Logic Pro ships with a large collection of audio loops, offering a great starting point for
many of your projects. This chapter explains how you can add pre-recorded media in
Logic Pro, including audio and MIDI files, Apple Loops, and other common loop
formats.
Supported File Formats
Logic Pro allows you to access any digitally stored audio recordings (audio files) on your
hard drives, in the most common Macintosh, and several other, file formats.
Audio files imported into a Logic Pro project can be at any supported bit depth and
sample rate. Logic Pro supports bit depths of 16, 20, and 24 bits, and sample rates of
44.1, 48, 88.2, 96, 176.4, and 192 kHz. Logic Pro can use the file’s sample rate, or can
perform a real time sample rate conversion (see “
Setting the Project Tempo ” on
page 145).
In addition to audio files, Logic Pro can also import MIDI and project information.
You can add the following pre-recorded media file types to a Logic Pro project:
 WAV (including Broadcast Wave), AIFF, and SDII (Sound Designer II) files
 CAF
 MP3 files
 Apple Lossless files
 AAC (MPEG Layer 4) files
 Apple Loop files (audio and software instrument types)
 ReCycle audio (REX, RCY)
