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.
The AIFF output faithfully captures every detail that the MP2 codec preserved. Quality cannot exceed the original MP2 encoding — a 192 kbps MP2 decoded to AIFF will sound identical to the MP2 source. The advantage is that subsequent editing and processing will not introduce any additional codec artifacts.
