.aifb — AIFF-C (Compressed)
Apple · 1988
AIFF-C (.aifb) is a compressed version of the AIFF audio format, offering high quality with reduced file sizes.
Key Features
- Supports lossless and lossy audio compression for reduced file size.
- Maintains high audio fidelity suitable for professional use.
- Based on the flexible IFF container structure.
- Widely compatible with professional audio software and hardware.
Best For
- Preserving audio quality while reducing file size.
- Situations requiring a balance between fidelity and storage.
- Professional audio workflows on macOS and cross-platform systems.
- When a widely supported uncompressed format like WAV is too large.
Less Ideal For
- Streaming audio directly to web browsers (MP3, AAC are better).
- Maximum compatibility with older portable music players (MP3 is king).
- Archiving spoken word where extreme fidelity isn't critical (Opus or AAC might suffice).
- When uncompressed, raw audio data is absolutely required (use standard .aiff or .wav).
Common Use Cases
- Archiving high-quality audio projects with limited storage.
- Distributing audio files where bandwidth or storage is a concern.
- Storing sound effects or voiceovers in game development.
- Professional audio editing and mastering workflows.
How to Open It
- On macOS, QuickTime Player, Logic Pro, GarageBand, and Audacity can open .aifb files.
- On Windows, Audacity, Adobe Audition, and VLC Media Player are excellent options.
- Many professional Digital Audio Workstations (DAWs) natively support AIFF-C files.
- Simply double-clicking might open it in your system's default audio player.
What is a .aifb file?
AIFF-C, often recognized by its .aifb extension, is a variation of the Audio Interchange File Format (AIFF) designed for compressed audio. It allows for efficient storage and transmission of high-quality audio without significant loss of fidelity, especially when using lossless compression techniques. This makes it a flexible choice for professionals who need to manage audio files while conserving disk space. It supports various bit depths and sample rates, making it suitable for a wide range of audio production tasks.

Common Problems with .aifb Files
Frequently Asked Questions
The .aiff extension typically denotes uncompressed AIFF, while .aifb explicitly indicates that the audio within the AIFF container is compressed using AIFF-C standards.
AIFF-C supports both lossless and lossy compression. The specific compression codec used determines if it's lossless or lossy.
Yes, .aifb files can be edited in most professional audio software, similar to uncompressed AIFF files, though editing compressed audio can sometimes introduce generational quality loss.
Technical Details
AIFF-C is a container format that supports compressed audio streams, typically using the "IMA/ADPCM" (shorten to "ALAW" or "ULAW" or "MAC3"/"MAC6" on older Macs) or "FLC" (for Sorenson) codecs. It is based on the IFF (Interchange File Format) structure. Unlike standard AIFF, AIFF-C explicitly indicates the use of compression, allowing playback software to decompress the audio on the fly.
