Core Production Software
Logic Pro
Logic Pro is a powerful hybrid 32/64 bit digital audio workstation (DAW)—a software application used for recording, editing, and producing audio files—and MIDI sequencer. Originally developed by Emagic before being acquired by Apple in 2002, it provides a full array of synthesizers, software instruments, and recording facilities.
The software includes a variety of audio effects such as equalization filters, dynamics processors, delays, and distortions. A standout feature is the Space Designer plugin, which uses convolution to simulate the acoustics of real-world environments, from small rooms to vast mountain echoes. Logic Pro also supports real-time musical notation, including drum notation, chord abbreviations, and guitar tablature.
For high-demand projects, Logic Pro supports distributed processing via an Ethernet LAN. By using the Logic node app on secondary machines, users can offload synth and effect processing to other computers on the network, achieving near-real-time performance on gigabit Ethernet connections.
MainStage
While Logic Pro is designed for the studio, MainStage is built for the stage. Its primary purpose is to centralize virtual instruments—typically used in Logic Pro—for use during live performances. These instruments can be triggered via MIDI controllers or pre-recorded MIDI files.
Beyond instrument hosting, MainStage functions as a multi-effects processor for vocals and guitars and allows performers to play back pre-recorded backing tracks.
Soundtrack Pro
Soundtrack Pro is a dedicated application for audio editing and music composition. It comes equipped with over 5,000 professional, royalty-free instrument loops and sound effects. To streamline the final delivery, multitrack projects can be exported directly using Compressor settings.
Specialized Utilities and Encoding
Compressor
Compressor is a professional media encoding application used primarily with Final Cut Studio and Logic Studio. It supports a wide range of formats, including MPEG-1, MPEG-2 (for DVD), QuickTime .mov, and MPEG-4 (H.264). Through third-party QuickTime Exporter Components, it can also export to formats like Windows Media.
Advanced features include the ability to convert between NTSC and PAL standards and the capacity to upconvert standard-definition video to high-definition, utilizing feature detail detection to maintain visual quality.
Apple Loops Utility
This companion utility for GarageBand, Logic, and Soundtrack Pro allows users to create audio loops that support time-stretching. It enables batch tagging, allowing multiple files to be assigned musical information (such as tempo and key) and publishing data (such as author and comments) simultaneously. While it reads both WAV and AIFF formats, it converts WAV files to AIFF when saving tagged information.
Waveburner and Impulse Response Utility
Waveburner is a multimedia content creator used for assembling, mastering, and burning audio CDs. It is designed for professional distribution, supporting up to 99 tracks, ISRC codes, CD-Text, and the creation of DDP (CD-image) files. It also includes features for copy prevention and pre-emphasis.
Additionally, Apple provides the Impulse Response Utility, a specialized tool used to create custom convolution reverbs for use in audio processing.

Frequently Asked Questions
What is the difference between Logic Pro and MainStage?
Logic Pro is a full digital audio workstation intended for recording and producing music in a studio setting. MainStage is a streamlined host for virtual instruments and effects specifically optimized for live performance.
Can Apple Loops Utility handle WAV files?
Yes, Apple Loops Utility can read WAV files; however, it will convert them to the AIFF format when saving the file with tagging information.
What is distributed processing in Logic Pro?
Distributed processing allows Logic Pro to offload the CPU-intensive processing of software instruments and plug-ins to other Mac computers on a local Ethernet network using the Logic node app.
What professional mastering features does Waveburner offer?
Waveburner supports professional industry standards including ISRC codes for track identification, UPC/EAN codes for the album, CD-Text, and the creation of DDP images for mass production.
How does Compressor handle video quality when upconverting?
When converting standard-definition video to high-definition, Compressor uses feature detail detection to help prevent serious quality losses during the upconversion process.
