Convert MP2 to AIFF

Why Convert MP2 to AIFF?

Converting MP2 to AIFF decodes compressed broadcast audio into uncompressed PCM within Apple's native audio container. This conversion is essential when broadcast recordings need to enter macOS-based production workflows — Logic Pro, GarageBand, and other Apple tools handle AIFF as their preferred working format, providing optimal performance for editing, processing, and mixing.

Broadcast archives often contain valuable content in MP2 format: historical radio programs, television audio tracks, live event recordings, and news broadcasts. Converting these to AIFF creates an editable, uncompressed copy that can be processed in professional DAWs without further quality degradation. While the AIFF file will contain the same audio quality as the decoded MP2 (not original studio quality), it provides a stable foundation for post-production work.

AIFF is particularly valuable in macOS-centric broadcast post-production environments. Facilities using Logic Pro for audio cleanup, restoration, and remastering benefit from AIFF's native integration and zero-overhead playback. The uncompressed format eliminates any MP2 decoding artifacts that might occur during real-time processing, ensuring predictable behavior with plugins and effects.

Be aware that AIFF files are substantially larger than MP2 — a 30-minute MP2 broadcast at 256 kbps (~56 MB) expands to approximately 300 MB as 16-bit/48 kHz AIFF. This size increase is the cost of having uncompressed, DAW-ready audio. For permanent archival, consider FLAC as a more storage-efficient lossless alternative to AIFF.

Key Benefits of Converting MP2 to AIFF:

• Apple DAW Native: Default format for Logic Pro and GarageBand
• Uncompressed PCM: No decoding overhead during editing and mixing
• No Further Degradation: Edit and re-save without generation loss
• Metadata Enhancement: Add ID3 tags, descriptions, and artwork to AIFF
• macOS Integration: Native support in Finder, QuickTime, iTunes
• Plugin Compatibility: No codec-related issues with audio effects
• Broadcast Post-Production: Standard format for Apple-based facilities

Practical Examples

Example 1: Radio Program Restoration in Logic Pro

Scenario: A radio station is restoring historical broadcast recordings stored in MP2 format, using Logic Pro on macOS for noise reduction, equalization, and remastering.

Source: historical_broadcast.mp2 (60 min, 192 kbps, 48 kHz, 84 MB)
Conversion: MP2 → AIFF (16-bit, 48 kHz)
Result: historical_broadcast.aiff (550 MB)

Restoration workflow:
1. Convert MP2 → AIFF for Logic Pro import
2. Apply noise reduction and hiss removal
3. Equalize and normalize audio levels
4. Add metadata (date, program, contributors)
5. Export restored version as AIFF master

Example 2: TV Audio Extraction for Documentary

Scenario: A documentary filmmaker extracts audio interviews from DVB television recordings (MP2) and needs uncompressed AIFF files for editing in Final Cut Pro on macOS.

Source: tv_interviews/ (20 clips, MP2, 256 kbps, 2.5 GB)
Conversion: MP2 → AIFF (16-bit, 48 kHz)
Result: tv_interviews_aiff/ (20 clips, 14 GB)

Documentary workflow:
✓ AIFF integrates natively with Final Cut Pro
✓ Uncompressed audio for precise editing
✓ 48 kHz maintains broadcast sample rate
✓ No quality loss during timeline operations
✓ Can add BWF-style metadata for project management

Example 3: Podcast Episode from Radio Broadcast

Scenario: A public radio station converts their over-the-air MP2 broadcasts into AIFF for post-production in GarageBand before publishing as podcasts.

Source: radio_show.mp2 (90 min, 192 kbps, 48 kHz, 126 MB)
Conversion: MP2 → AIFF (16-bit, 44.1 kHz)
Result: radio_show.aiff (900 MB)

Podcast preparation:
✓ GarageBand reads AIFF natively
✓ Edit out commercials and station breaks
✓ Add intro/outro music and transitions
✓ Normalize levels for podcast standards
✓ Export final podcast as AAC or MP3

Frequently Asked Questions (FAQ)

Q: Does converting MP2 to AIFF restore lost audio quality?

A: No. MP2 is a lossy format that permanently discards audio data during encoding. Converting to AIFF creates a perfect, uncompressed copy of the decoded MP2 audio — but the quality ceiling is set by the original MP2 encoding. The AIFF file will sound identical to the MP2, just in an editable, uncompressed container.

Q: Why choose AIFF over WAV for the converted files?

A: Choose AIFF if you work primarily on macOS with Logic Pro, GarageBand, or Final Cut Pro — AIFF is Apple's native PCM format with seamless integration. If you work cross-platform or on Windows, WAV is more universal. The audio quality is identical in both formats; only the container and byte order differ.

Q: How much larger will AIFF files be compared to MP2?

A: Significantly larger. A 60-minute MP2 at 256 kbps is approximately 112 MB. The same content as 16-bit/48 kHz AIFF is approximately 550 MB — roughly 5x larger. At 192 kbps MP2, the ratio is even more dramatic (~7x). This is the trade-off for having uncompressed, editable audio.

Q: What sample rate should I use for the AIFF output?

A: Match the MP2 source sample rate for a faithful conversion. Most broadcast MP2 uses 48 kHz. If your MP2 is 48 kHz, convert to 48 kHz AIFF. For CD-standard output, 44.1 kHz is appropriate. Never upsample (e.g., 48 kHz MP2 to 96 kHz AIFF) — it increases file size without adding any audio detail.

Q: Can Logic Pro import MP2 files directly?

A: Logic Pro can import some compressed formats, but MP2 support is inconsistent. Pre-converting to AIFF guarantees reliable import, avoids potential compatibility issues, and gives you control over the output format settings. For a smooth professional workflow, always convert MP2 to AIFF before importing into any DAW.

Q: Is AIFF good for long-term archival of broadcast content?

A: AIFF is acceptable for archival but FLAC is generally better — it provides identical audio quality at roughly half the storage cost with better metadata support and built-in checksums. Use AIFF as your working format during production and FLAC for long-term archival. Both preserve the full decoded MP2 audio without further loss.

Q: Will my broadcast MP2 files have any metadata to transfer?

A: MP2 has very limited metadata capability. Most broadcast MP2 files contain little or no embedded metadata. The conversion to AIFF is an opportunity to add comprehensive metadata: program name, broadcast date, contributors, copyright information, and even embedded artwork using AIFF's ID3 tag support.

Q: How long does MP2 to AIFF conversion take?

A: Very fast. MP2 decoding is computationally simple, and writing uncompressed AIFF is purely disk I/O. A 60-minute broadcast recording converts in 1-2 seconds on modern hardware. The bottleneck is disk write speed for the larger AIFF output, not CPU processing. Batch conversion of dozens of files completes in seconds.
