AIFC (Audio Interchange File Format - Compressed) is an extension of Apple's AIFF that supports compressed audio codecs within the IFF-based container. AIFC files may contain Apple's Mace 3:1/6:1, IMA ADPCM, or even uncompressed PCM data with a different byte-order marker. Android's Stagefright media framework has no built-in decoder for the AIFC container — the format is not recognized by Android's media scanner, meaning AIFC files transferred to an Android device are completely invisible to the native music player and most third-party apps.
AIFC is a relic of early Macintosh multimedia authoring and legacy Mac sound systems. Files in this format are occasionally found in archived Mac software, old HyperCard stacks, and vintage multimedia CD-ROMs. Since Android has zero AIFC support at any level, converting to Android Audio (AAC in M4A) is the only way to play this audio on Android phones, tablets, and Android-based car infotainment systems.
This conversion also serves archival purposes — AIFC is a declining format with no modern software actively producing it. Converting to a widely supported format like AAC ensures the audio content remains accessible as AIFC support continues to erode across platforms.
FFmpeg identifies the AIFC container variant (compressed or uncompressed PCM with AIFC headers) and decodes the audio to raw PCM. For Mace-compressed AIFC, the legacy codec is decoded to 16-bit PCM at the original sample rate. The PCM is then encoded to AAC-LC at 128-256 kbps in an M4A container with Android-compatible metadata. If the AIFC contains IMA ADPCM, decoding restores the full PCM dynamic range before AAC encoding.
AIFC files compressed with Mace 3:1 or 6:1 were already heavily degraded — these were 1990s codecs optimized for System 7 on Motorola 68k processors. AAC encoding from these sources preserves the existing quality without additional degradation. For AIFC files containing uncompressed PCM, the AAC encode is a clean single-generation lossy conversion with excellent results at 192+ kbps.
