OGG Vorbis delivers lossy compressed audio with excellent quality-per-bitrate from Xiph.org's open-source project. AIFF (Audio Interchange File Format) is Apple's uncompressed PCM audio container, created in 1988, storing raw audio samples at full fidelity with big-endian byte order. AIFF is the traditional uncompressed format for macOS audio production.
Converting OGG to AIFF decodes the Vorbis-compressed audio to raw PCM samples and stores them in Apple's AIFF container. This prepares the audio for professional editing in DAWs that prefer or require uncompressed input, preventing cumulative generation loss during processing.
Professional audio editing workflows require uncompressed input to avoid compounding artifacts with each processing step. Converting OGG to AIFF creates the uncompressed PCM baseline that Logic Pro, GarageBand, and Pro Tools expect. The decoded Vorbis audio is captured at full decoded fidelity, ready for effects processing, mixing, and mastering.
AIFF is also the expected delivery format for some mastering facilities and broadcast systems running on macOS. When OGG files must enter an Apple-native production pipeline, AIFF conversion is the standard preparation step.
FFmpeg decodes the Vorbis stream from the OGG container to PCM (signed 16-bit or 24-bit), then writes the samples into an AIFF container with big-endian byte order. The output preserves the source sample rate (typically 44.1 kHz or 48 kHz) and channel layout. A 5-minute Vorbis file at quality 5 (~10 MB) expands to approximately 50 MB as 16-bit 44.1 kHz stereo AIFF.
The conversion itself is lossless — every decoded Vorbis sample is stored perfectly in AIFF. However, AIFF cannot restore information discarded during the original Vorbis encoding. The AIFF output sounds identical to the OGG source but occupies significantly more disk space. Think of it as a perfect capture of what the Vorbis encoder preserved.
