About MP2 to AIFF Conversion
Converting MP2 to AIFF decodes broadcast-standard MPEG Audio Layer 2 and stores the resulting PCM in Apple's uncompressed format. MP2's typical broadcast quality (192-384 kbps at 48 kHz) decodes to high-quality PCM that AIFF preserves without any additional degradation.
This conversion is standard in broadcast post-production — extracting MP2 audio from DVB transport streams or DAB recordings into AIFF for editing in professional DAWs on macOS. AIFF's uncompressed format provides the optimal editing environment for broadcast audio processing.
Why Convert MP2 to AIFF?
Broadcast post-production on Apple systems uses AIFF as the standard editing format. Extracting MP2 audio from broadcast streams into AIFF enables editing in Logic Pro, Pro Tools, and Final Cut Pro without the overhead of real-time MP2 decoding during timeline scrubbing.
AIFF also serves as an archival decode format for broadcast MP2 content. Institutions that archive broadcast audio may decode MP2 to AIFF for long-term preservation, ensuring the decoded audio is accessible without MP2 decoding infrastructure.
Common Use Cases
- Extracting DVB broadcast audio from MP2 to AIFF for post-production editing
- Decoding DAB radio recordings to AIFF for mastering and rebroadcast preparation
- Archiving broadcast MP2 audio in uncompressed AIFF for institutional preservation
- Creating edit-ready audio from DVD-Video MP2 tracks for film post-production
- Preparing broadcast MP2 recordings for mixing and music production in Logic Pro
How It Works
FFmpeg decodes the MP2 subband audio to PCM at the source sample rate (typically 48 kHz for broadcast, 44.1 kHz for consumer) and writes it into an AIFF container with big-endian byte order. The output is usually 16-bit or 24-bit depending on requirements. Broadcast MP2 at 384 kbps decodes to full-bandwidth stereo with quality approaching CD level.
Quality & Performance
AIFF output preserves the full decoded quality of the MP2 source. MP2 at 384 kbps provides excellent broadcast audio — the decoded AIFF captures this quality without adding any artifacts. The file is approximately 5-10x larger than the MP2 source. No quality improvement occurs — AIFF stores exactly what the MP2 decoder produces.

Tips for Best Results
- 1Preserve the 48 kHz sample rate from broadcast MP2 — do not downsample for editing
- 2Use 24-bit AIFF if your DAW project uses 24-bit sessions, even though the MP2 source is 16-bit equivalent
- 3For archival, consider FLAC over AIFF for 40-60% storage savings with identical quality
- 4Add broadcast metadata (date, channel, program) during conversion for proper archive cataloging
- 5Batch decode MP2 broadcast recordings to AIFF for efficient post-production preparation
