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.
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.
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.
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.

MP2 to AIFF is the standard path for extracting broadcast audio into an uncompressed editing format. Quality equals the decoded MP2 source.
