MPG files from DVDs, VCDs, and broadcast captures carry MP2 audio at bitrates typically between 128 and 384 kbps. AIFF (Audio Interchange File Format) is Apple's uncompressed audio format storing raw PCM data — the standard interchange format for professional audio production on macOS. Converting MPG to AIFF decodes the legacy MP2 audio and saves it as uncompressed PCM, producing files ready for editing in Logic Pro, GarageBand, and other macOS DAWs.

Professional audio editing requires uncompressed input to prevent further quality degradation during processing. If you have audio in MPG files — dialogue from DVD rips, broadcast recordings, or VCD captures — converting to AIFF gives you a format that macOS audio tools handle natively. Every filter, effect, and edit can be applied without worrying about codec artifacts accumulating.

FFmpeg decodes the MP2 audio stream from the MPG container and outputs it as signed 16-bit big-endian PCM in the AIFF container. The typical output is 44.1 kHz or 48 kHz stereo (matching the source sample rate). AIFF files are approximately 10 MB per minute for CD-quality stereo audio. The conversion is straightforward — MP2 decode → PCM write — with no intermediate processing unless resampling is requested.

No. AIFF preserves the decoded MP2 audio exactly — it cannot restore detail lost during MP2 encoding. The benefit is having uncompressed audio for editing without further quality loss.

Approximately 10 MB per minute for 44.1 kHz stereo 16-bit audio. A full DVD movie's audio track could be 1-1.5 GB in AIFF.

AIFF is preferred on macOS (Logic Pro, GarageBand). WAV is more universal across platforms. Audio quality is identical. Choose based on your production environment.

Yes. FFmpeg handles both MPEG-1 Layer II and MPEG-2 Layer II (MP2) audio. Both are decoded to PCM and saved as AIFF identically.

AIFF supports ID3-like metadata tags, but MPG files typically contain minimal audio metadata. Any available tags will be preserved where possible.
