Convert XviD to AIFF — Free Online Converter

XviD emerged from the open-source community as a free alternative to DivX — its name a deliberate reversal of the proprietary codec it aimed to replace. Scene release groups adopted XviD as their standard codec, encoding DVD rips into 700 MB AVI files that could be burned to a single CD-R and traded across the early internet. The audio in these releases was typically MP3 at 128-192 kbps, though DVD rips sometimes carried AC3 surround sound.

AIFF (Audio Interchange File Format) is Apple's uncompressed PCM audio standard, storing raw audio samples without any compression. Converting XviD to AIFF extracts the compressed audio track and decodes it into uncompressed PCM data — providing a lossless foundation for professional audio editing on macOS in Logic Pro, GarageBand, and Final Cut Pro.

Professional audio workflows on macOS require uncompressed input for editing, mastering, and sound design. AIFF is the native uncompressed format for Apple's creative tools, and importing AIFF into Logic Pro or Final Cut Pro avoids any runtime decoding overhead. If you need audio from XviD recordings for sampling, sound design, or podcast production, AIFF provides the cleanest possible starting point.

Unlike lossy formats like AAC or MP3, AIFF preserves every sample from the decoded audio without any additional compression. While you cannot recover quality lost in the original MP3 encoding, AIFF ensures no further degradation occurs — making it a safe intermediate format for multi-step production workflows.
