Supported file formats in Logic Pro for iPad
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, 24, and 32 bits and sample rates of 44.1, 48, 88.2, and 96 kHz. Logic Pro can use the file’s sample rate, or it can perform a real-time sample rate conversion if it differs from the project sample rate.
In addition to audio files, Logic Pro can also import MIDI files.
You can import the following file formats into Logic Pro:
WAV and AIFF files: Wave (WAV) and Audio Interchange File Format (AIFF) audio files are very similar. They can be stored at different bit depths (16, 24, and 32 bit are supported by Logic Pro), in mono and stereo, and at sample rates up to 96 kHz.
Core Audio Format files: Core Audio Format (CAF) files are containers that support integer and float PCM formats, A-law, u-law, and a number of others, including AAC and the Apple Lossless Audio Codec (ALAC). Unrestricted file sizes are possible, at high sample rates and bit depths.
MP3, Apple Lossless, and AAC files: MP3 and AAC files contain compressed audio information. They are usually much smaller than equivalent WAV and AIFF files. This reduction in file size is due to encoding techniques that “throw away” some of the audio information. As a result, there may be a loss in audio quality compared to their WAV or AIFF audio counterparts, depending on the source audio material. Apple Lossless files also contain compressed audio information. As the name suggests, the compression used (ALAC) does not discard audio information in the same fashion as MP3 and AAC files. The sound of the compressed audio file is identical to the original recording.
Apple Loops: Audio loops contain additional metadata, such as time and date, category, mood, key, and tempo. They also contain a number of transient markers, which break them down into small time slices. The main advantage of Apple Loops is their ability to automatically match the tempo and key of a Logic Pro project. MIDI, Session Player, and pattern loops contain information about the included MIDI notes and the required instrument patch. When added to a software instrument track, the MIDI note information can be edited the same way as any MIDI region. When added to an audio track, an audio version of the loop is created.
Standard MIDI files: Standard MIDI file (SMF) is the standard file format used in MIDI sequencers. Standard MIDI files can be read and saved in Logic Pro. MIDI files may contain note, lyric, controller, and SysEx data. You can add them to software instrument tracks in your project.
