What is an AIFC file?
The AIFC extension represents the AIFF-C (Audio Interchange File Format - Compressed) standard, an extension of the original AIFF specification developed by Apple. Unlike standard AIFF, which stores uncompressed PCM data, AIFC supports various compression codecs defined in the format's 'COMM' chunk, such as IMA 4:1, MACE 3:1, MACE 6:1, ALAW, and ULAW. This allows for reduced file sizes while maintaining the chunk-based structure of the EA IFF 85 standard. It is commonly used in legacy gaming audio and QuickTime applications.
How to open an AIFC file
AIFC files are natively supported on macOS via QuickTime Player and Apple Music. On Windows, native support is limited; however, legacy versions of Windows Media Player may open them if the specific internal codec (e.g., IMA ADPCM) is supported. The most reliable method for opening AIFC files on non-Apple operating systems is VLC Media Player or the cross-platform command-line tool FFmpeg, both of which can decode the specific compression algorithms wrapped within the AIFC container.

What is an AIFF file?
The AIFF (Audio Interchange File Format) is a lossless audio container format developed by Apple Inc., functioning as the standard uncompressed audio format for the Macintosh platform. Based on the EA IFF 85 standard, AIFF files store data in Pulse Code Modulation (PCM) format using big-endian byte ordering. It is functionally analogous to the WAV format used on Windows but differs in its header structure and byte sequence. AIFF is widely used in professional audio recording and editing due to its lack of compression artifacts and high-fidelity signal retention.
How to open an AIFF file
AIFF is the native uncompressed audio format for macOS, allowing files to be opened immediately in QuickTime, Apple Music, and Logic Pro. Windows users can open AIFF files using Windows Media Player, though some metadata may not render correctly. For professional manipulation or playback on Linux and Windows systems, VLC Media Player and Adobe Audition are the industry-standard recommendations, ensuring accurate interpretation of the big-endian PCM data streams.
