MPEG-2 to AIFC Converter

MPEG-2 to AIFC Converter

An MPEG-2 file (.mpeg2) is a DVD-era video program stream that carries MPEG-2 video alongside an MP2 audio track. AIFC (.aifc, AIFF-C) is Apple's audio container, used here to hold uncompressed PCM audio. This tool extracts the audio from the MPEG-2 stream, discards the video, and writes the result as an AIFC file — useful when you want the soundtrack as an editable, uncompressed track for macOS or pro-audio work.

One thing to understand up front: the source MP2 audio is lossy, and decoding it to PCM cannot recover detail that lossy encoding already discarded. The AIFC output will be noticeably larger than the original audio track with no gain in fidelity. If you just want a small, shareable file, an MP3 or M4A is the better target; choose AIFC when an editor or workflow specifically needs uncompressed PCM.

How to Convert MPEG-2 to AIFC

1. Upload Your MPEG-2 File: Drag and drop your .mpeg2 file or click "+ Add Files" to select it from your computer.
2. Set Audio Sample Rate: Leave "Original" to keep the source rate, or pick a value (8000 Hz up to 48000 Hz) if your editor expects a specific rate.
3. Set Audio Channel: Leave "Original" to preserve the source layout, or choose Mono to halve the file size or Stereo to force a two-channel track.
4. Convert and Download: Click "Convert" to extract the audio to AIFC. No sign-up, no watermark.

Frequently Asked Questions

What is the difference between AIFF and AIFC?

AIFF (1989) stores only uncompressed PCM audio. AIFC, also written AIFF-C (Apple's revision dated August 26, 1991), is a superset: its COMM chunk adds compression-type fields so the container can hold codecs like A-law or µ-law. When the compression type is "NONE" — which is what this tool writes — an AIFC file is simply uncompressed big-endian PCM, functionally the same audio as an AIFF.

Will converting MPEG-2 to AIFC improve the audio quality?

No. MPEG-2 program streams carry lossy MP2 audio, and decoding that to PCM cannot rebuild detail the original encoder already threw away. AIFC gives you an uncompressed, edit-friendly copy of whatever the MP2 track already sounds like — not a higher-fidelity version of it.

Why is my AIFC file so much larger than the MPEG-2 audio?

Because uncompressed PCM stores every sample at full size. In our testing, a few minutes of MP2 audio that occupied a small fraction of an MPEG-2 file expanded several-fold once written as 16-bit big-endian PCM AIFC. That is expected: you are trading compactness for an uncompressed, editor-ready track. If size matters more than uncompressed audio, convert to MP3 or M4A instead.

What does this tool do with the MPEG-2 video track?

It discards it. This is an audio-extract conversion: only the audio stream is decoded and written to AIFC, and the MPEG-2 video is dropped entirely. If you need to keep the video, use a video-to-video converter instead.

What plays an AIFC file once I've converted it?

QuickTime Player, VLC, and Audacity open AIFC directly, and most professional DAWs import it. Because the output here is plain big-endian PCM (compression type "NONE"), it is widely readable; the compatibility caveats you may have read about apply to compressed AIFC variants, which this tool does not produce.

Should I pick AIFC or WAV for uncompressed audio?

Both hold uncompressed PCM, so the audio is identical. AIFC uses big-endian byte order and is the more idiomatic choice in macOS and Apple-centric audio workflows, while WAV (little-endian) is the more universal default on Windows and for general interchange. If your editor reads both, pick whichever your project already uses; if you're unsure, WAV is the safer cross-platform option.

Are my files private during conversion?

Yes. Your file is uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours. There's no sign-up, no watermark, and your files are never shared or made public.
