MPG to AIFF Converter

MPG to AIFF — Extract the Soundtrack as Uncompressed Audio

This tool pulls the audio track out of an MPG (MPEG Program Stream) video and saves it as AIFF, discarding the picture. The honest catch worth knowing up front: an MPG's audio is already lossy (usually MP2), so the AIFF you get is a lossless container wrapped around already-lossy audio — bigger on disk, but it cannot restore anything the original compression threw away. Extract to AIFF when your destination is a Mac DAW that wants uncompressed PCM input; if you just want a small shareable file, MPG to MP3 is the better fit.

MPG Audio vs AIFF — Side-by-side

When to Extract MPG Audio to AIFF

• You're importing into a Mac DAW — AIFF is the native bounce format for Logic Pro, GarageBand, and Final Cut Pro, and Pro Tools imports it without conforming. No decoder plugin, no byte-order conversion.
• You'll edit the audio further — uncompressed PCM stops generational loss. Every EQ pass, gain stage, and re-export stays bit-faithful from here on, even though the starting material was lossy MP2.
• You're archiving the soundtrack separately — pulling a DVD rip's or broadcast capture's audio into a standalone uncompressed file keeps it editable without re-decoding the whole MPG each time.
• A sample library or forensic tool expects AIFF/WAV — Kontakt, EXS24, and iZotope RX work cleanly on uncompressed PCM without artifacts from re-decoding compressed audio.

When to Pick Something Else Instead

• You want a small file to share or upload — AIFF balloons to ~10 MB per minute. MPG to MP3 re-compresses to a few hundred KB per minute with no false "lossless" framing.
• Your editing host is a Windows DAW — WAV is the same uncompressed PCM in little-endian (Microsoft) order. MPG to WAV avoids a byte-order conversion on Windows hosts.
• You only need the audio for casual playback — a lossy format is smaller and sounds identical for listening; reserve AIFF for editing pipelines.

How to Convert MPG to AIFF

1. Upload Your MPG File: Drag and drop or click "Add Files" to add MPG or MPEG video. DVD rips, broadcast captures, and legacy MPEG-1/MPEG-2 clips all work; batch is supported.
2. Set Audio Sample Rate and Audio Channel: Leave both at "Original" to match the source (typically 48000 Hz for MPEG-2 video, 44100 Hz for MPEG-1), or downsample for speech. Pick the channel layout — keep the source's stereo or downmix to mono.
3. Pick the PCM Codec and Trim (Optional): Under Show All Options, the Audio Codec defaults to "PCM 16-bit Big Endian" for standard AIFF; choose a higher bit depth for editing headroom. Optionally set a start time and duration to extract one segment.
4. Convert and Download: Click Convert. Files process on our servers and download individually or as a ZIP — no sign-up, no watermark.

Frequently Asked Questions

Why is the AIFF bigger than the original MPG if it came from the same audio?

Because AIFF is uncompressed. The MPG stores audio as lossy MP2 at a few hundred kilobits per second; decoding that to PCM expands it to ~1411 kbps (about 10 MB per minute of CD-quality stereo). You're not gaining quality — you're spending disk space to stop further compression. A short MPG clip can easily produce an AIFF that rivals the whole video file in size, which is normal and expected.

Does extracting to AIFF make the audio lossless?

Only the container is lossless. The audio inside an MPG is already lossy (MP2, sometimes MP3 or AC-3), so the AIFF is a bit-perfect decode of that already-compressed signal — it carries the same artifacts the original encoder baked in. AIFF prevents any further loss during editing, but it cannot recover detail the MP2 step discarded. For the best result, start from the highest-bitrate MPG you have.

Why pick AIFF over WAV when extracting from MPG?

Both are uncompressed PCM and identical in audio quality and size; the difference is byte order and ecosystem. AIFF is big-endian (Apple convention) and is the default for Logic Pro, GarageBand, and Final Cut Pro, so it round-trips inside the Apple world without conversion. WAV is little-endian (Microsoft convention) and is the Windows DAW default — for that target, use MPG to WAV.

What sample rate should I choose?

Match the source to avoid a resampling step. MPEG-2 sources (DVDs, broadcast, ATSC) are usually 48000 Hz; MPEG-1 sources and music-CD-rate material are 44100 Hz. Leaving Audio Sample Rate on "Original" preserves the native rate. Resampling is mathematically clean but pointless here, since it can't add detail that the lossy source never had.

Should I extract at 16-bit or a higher bit depth?

16-bit PCM matches CD and broadcast delivery and is plenty for a finished file. A higher bit depth gives extra headroom if you'll do further EQ, compression, or gain staging — but it does not recover quality lost in the original MP2 encode. In our testing, a one-minute stereo MPG clip extracted at 16-bit/44.1 kHz produces an AIFF of roughly 10 MB; moving to 24-bit raises that to about 16 MB without making the already-lossy source sound better.

How are my files handled, and how long are they kept?

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

What if my MPG has multiple audio tracks?

The extraction takes the primary audio track. AIFF can hold multi-channel audio (5.1, 7.1) at the right channel count, but a single-file extract typically outputs stereo or mono — pick the channel layout you need. For discrete surround channels from a DVD rip, a multi-track DAW import is usually the better workflow than one flattened file.
