MPEG-2 to AIFF Converter

Extract AIFF Audio from MPEG-2: What This Tutorial Covers

This walks you through pulling the soundtrack out of an MPEG-2 file — a DVD-Video rip, a DVB or ATSC broadcast capture, or a .mpeg2 / .m2v master — and saving it as uncompressed AIFF for a Mac or pro-audio workflow. The picture is discarded; you get an audio-only file. The one thing to understand up front: MPEG-2 audio is already lossy (MP2 or AC-3), so AIFF gives you a clean, edit-friendly file but cannot add back detail the original compression threw away.

How to Extract AIFF Audio from MPEG-2

1. Upload Your MPEG-2 File: Drag and drop or click "Add Files" to select .mpeg2, .mpg, .m2v, or DVD .vob-style MPEG-2 video. Batch is supported — drop a whole folder of DVD chapters or broadcast captures and extract them in one pass.
2. Set Audio Sample Rate: Leave Audio Sample Rate on "Original" to keep the source rate (48000 Hz is standard for DVD/broadcast MPEG-2), or pick a specific rate to resample. The output is written as 16-bit big-endian PCM (PCM_S16BE) AIFF — the macOS default — so quality is set by the source and the sample rate, not by a bitrate.
3. Set Audio Channel and Trim (Optional): Use Audio Channel to keep the original layout or force Stereo / Mono, and use Trim (Start time + Duration, in HH:MM:SS.sss) to pull just one song, scene, or dialogue line instead of the whole track.
4. Convert and Download: Click Convert. Files process on our servers and download individually or as a ZIP — no sign-up, no watermark.

Walk-through: getting the audio you actually want

The default extraction takes the file's primary audio track, decodes it from MP2 or AC-3 into uncompressed PCM, and wraps it in an AIFF container. For most DVD and broadcast sources that is exactly what you want. A few decisions change the result:

• Want it to drop straight into Logic Pro or Pro Tools? Leave sample rate on "Original" (48000 Hz for MPEG-2) and keep Stereo. AIFF is the native bounce format for Logic, GarageBand, and Final Cut Pro, so it imports without conforming or re-encoding.
• Want a smaller working file for speech? Set Audio Channel to Mono and Audio Sample Rate to 22050 Hz. A minute of mono 22.05 kHz PCM is roughly a quarter the size of stereo CD-rate PCM.
• Want just one segment? Use Trim — enter a Start time and a Duration. Both accept plain seconds (90) or HH:MM:SS.sss (00:01:30.500). Handy for isolating a single track from an MPEG-2 concert capture or one chapter from a DVD rip.
• Source is 5.1 (AC-3 surround)? See the FAQ below — the extract is down-mixed to stereo by default rather than preserving discrete surround channels.

Common Errors and How to Fix Them

• "The AIFF is huge — bigger than I expected" — That is normal. AIFF is uncompressed PCM at about 10 MB per minute of 16-bit/44.1 kHz stereo (≈1411 kbps), while the MPEG-2 audio inside the video was a 192-384 kbps lossy stream. You are trading size for an edit-stable file, not gaining quality. For a small portable file, use MPEG-2 to MP3 instead.
• "The audio still sounds compressed" — AIFF is a bit-faithful decode of whatever was in the MPEG-2 file. If the source was 192 kbps MP2, the AIFF carries that codec's artifacts; PCM stops further degradation but cannot undo it. Start from the highest-bitrate MPEG-2 source you have.
• "It came out mono / lost a channel" — Check the Audio Channel setting. If the source is multichannel AC-3 and you need both fronts, choose Stereo for an L/R down-mix.
• "Output is silent" — The MPEG-2 file may have no audio track, or its audio is on a secondary track. Confirm the source plays with sound in a media player first.

When This Doesn't Work

A few MPEG-2 sources need a different path. Commercial DVD-Video that is CSS-encrypted has to be decrypted by your ripper before upload — this tool processes the MPEG-2 stream it receives, not protected disc images. If your MPEG-2 file has multiple discrete AC-3 surround channels and you need all of them preserved as separate tracks (rather than a stereo down-mix), a multi-track DAW import is the better route. And if you actually want to keep the video and only re-encode the audio, this is the wrong tool — it discards the picture by design.

Frequently Asked Questions

Will the AIFF restore quality lost by the MPEG-2 audio?

No. MPEG-2 carries lossy audio — MP2 (MPEG-1 Layer II) or AC-3 (Dolby Digital) — and AIFF stores uncompressed PCM. Decoding lossy audio into a lossless container makes the file much larger but cannot recover detail the original compression discarded. "Lossless container" is not the same as "lossless audio." In our testing, a one-minute DVD-rip clip with 192 kbps MP2 audio produced an AIFF around 10 MB at 16-bit/44.1 kHz stereo — about 30x the size of the original audio, with no added fidelity. AIFF's value is that it stops any further generational loss while you edit.

What audio codec and bit depth does the AIFF use?

The converter writes PCM_S16BE — 16-bit big-endian PCM — which is the standard, macOS-default AIFF format. AIFF (Audio Interchange File Format) was introduced by Apple in 1988, based on Electronic Arts' IFF, and stores uncompressed PCM; big-endian byte order is the Apple convention, which is what makes AIFF the Mac counterpart to Windows' little-endian WAV.

What sample rate should I choose for MPEG-2 audio?

Most MPEG-2 audio — DVD-Video, DVB, and ATSC broadcast — is at 48000 Hz, so leaving Audio Sample Rate on "Original" keeps it bit-faithful. Music CDs and some MPEG-1 sources are 44100 Hz. For speech or podcast extraction you can downsample to 22050 Hz to save space. Mismatching the rate adds a clean resampling step but no benefit.

What if my MPEG-2 file has 5.1 surround (AC-3) audio?

MPEG-2 Part 3 and AC-3 support up to 5.1 multichannel. This extraction takes the primary audio track and down-mixes to stereo by default rather than preserving discrete surround channels. AIFF itself can hold multichannel audio, but if you need all six channels kept separate, import the MPEG-2 into a multi-track DAW instead of using a single-file extract.

Why pick AIFF over WAV when extracting from MPEG-2?

Both are uncompressed PCM and are equal in audio quality. AIFF is big-endian and is the default bounce/import format for Logic Pro, GarageBand, and Final Cut Pro, so it round-trips inside the Apple ecosystem without byte-order conversion. WAV is the little-endian Windows DAW default — if your target is a PC workflow, use MPEG-2 to WAV.

How long do you keep my uploaded MPEG-2 file?

Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion. There is no sign-up and no watermark, and files are never shared or made public. The practical limit on a big DVD rip is upload size and time, not your device.

How do I get the audio back to a small, shareable file later?

After editing the AIFF in Logic or Pro Tools, export to a compressed delivery format. For a portable file straight from the source, skip AIFF and use MPEG-2 to MP3; for lossless archival at roughly half the size of AIFF, convert your edited audio with AIFF to FLAC.
