Converting OGA to AIFF decodes Ogg Audio content and stores the resulting PCM in Apple's uncompressed AIFF format. This conversion bridges the open-source audio world (Xiph.org's Ogg container) with Apple's professional audio ecosystem (Logic Pro, GarageBand, Final Cut Pro).
For OGA files containing Vorbis, the decoded audio includes Vorbis compression artifacts. For OGA files containing FLAC, the decoded audio is a bit-perfect reconstruction of the original source — AIFF captures this lossless quality in an Apple-compatible uncompressed container.
Apple's professional tools work most efficiently with uncompressed AIFF for editing and mixing. If you have audio in OGA format from Linux-based recording workflows, open-source music production, or podcast recording that needs editing on macOS, converting to AIFF provides the optimal editing format.
AIFF also serves as a reliable intermediate format for further processing or format conversion. Decode OGA to AIFF once, then export to any needed format without re-reading the Ogg container.
FFmpeg reads the Ogg container, decodes the Vorbis or FLAC audio to PCM, and writes the samples into an AIFF container with big-endian byte order. Output is typically 16-bit/44.1 kHz or 16-bit/48 kHz depending on the source. OGA/FLAC sources decode to the original bit depth and sample rate. The AIFF file is significantly larger than the OGA — approximately 10x for Vorbis and 2-3x for FLAC.
From OGA/FLAC: AIFF output is bit-perfect — identical to the original uncompressed audio. From OGA/Vorbis: AIFF captures the decoded Vorbis audio without additional degradation. Quality is limited by the Vorbis encoding but no further artifacts are added. The AIFF stores everything the decoder produces.
