Supports: MPG, MPEG
PCM_S16BE for standard 16-bit AIFF (CD-quality, the macOS default) or PCM_S24LE / PCM_S32LE for high-resolution mastering. AIFF is uncompressed by design, so every codec preserves bit-faithful audio — pick by bit depth, not by compression.AUDIO_SAMPLE_RATE (typically 48000 Hz for MPEG-2 video, 44100 Hz for MPEG-1) or downsample to 22050 Hz / 16000 Hz for speech. Pick STEREO or MONO. Optionally trim using start time + duration in HH:MM:SS.sss format (e.g., 00:01:30.500).MPEG (typically MPEG-1 Part 2 or MPEG-2 Part 2 video) is a legacy container with audio encoded as MPEG-1 Layer II, MPEG-1 Layer III (MP3), or AC-3. The video carries a compressed audio track that's fine for playback but lossy and Windows-PC-centric. AIFF (Audio Interchange File Format), introduced by Apple in 1988, stores uncompressed PCM audio — the macOS counterpart to WAV — and is the native bounce format for Logic Pro, GarageBand, Pro Tools, and Final Cut Pro. Extracting AIFF from MPEG is the standard first step in pulling video audio into a Mac DAW workflow.

Often the AIFF audio file is comparable in size to the entire MPEG video, because AIFF is uncompressed (~10 MB per minute of stereo CD-quality audio) while MPEG video compresses both video and audio aggressively. A 50 MB MPEG-2 clip might yield a 35-40 MB AIFF when extracted at 16-bit/48 kHz stereo. This is normal and expected — you're trading file size for lossless fidelity. If size matters more than fidelity, see MPEG to MP3 instead.
AIFF and WAV are both uncompressed PCM containers and are functionally equivalent in audio quality. AIFF is big-endian (Apple convention) and is the default for Logic Pro, GarageBand, and Final Cut Pro — it round-trips inside the Apple ecosystem without byte-order conversion. WAV is little-endian (Microsoft convention) and is the Windows DAW default. If your editing target is a Mac DAW, pick AIFF; if cross-platform with Windows hosts, see MPEG to WAV.
For MPEG-2 sources (DVDs, broadcast, ATSC): 48000 Hz is the standard rate. For MPEG-1 sources and music CDs: 44100 Hz. For high-resolution mastering: 96000 Hz. Mismatching introduces a resampling step, which is mathematically clean but adds a tiny bit of processing time. Matching the source preserves bit-faithful audio.
16-bit (PCM_S16BE) is plenty for delivery-grade audio and matches CD/broadcast standards. 24-bit (PCM_S24LE) is preferred when you'll do further editing — equalization, compression, gain staging — because the 8 extra bits give you ~48 dB of headroom before quantization noise becomes audible. The MPEG source is rarely better than 16-bit equivalent quality, so going to 24-bit doesn't recover lost quality, but it future-proofs the file for editing.
Yes. Use the trim option to enter start time and duration. Both accept seconds (12.5) or HH:MM:SS.sss format (00:02:15.250). Useful for pulling a single song from an MPEG-2 concert recording, isolating a dialogue line from a broadcast capture, or extracting one chapter of audio from a DVD rip.
Yes — AIFF is uncompressed, but it can only preserve what's in the source. If the MPEG contains MP2 audio at 192 kbps, the resulting AIFF is a bit-perfect decode of that MP2, which means it carries the same lossy compression artifacts already baked in. AIFF doesn't restore lost quality; it just stops further degradation. For best results, work from the highest-bitrate MPEG source you have.
The default extraction takes the primary audio track. AIFF supports multi-channel audio (5.1, 7.1) when set to the appropriate channel count, but most browser-based extractions output stereo or mono — pick STEREO for the L/R downmix. For full discrete 5.1 channel preservation, AIFF supports it but you'll typically want a multi-track DAW import workflow rather than a single-file extract.
Yes — drop in entire folders of MPG/MPEG files. Each extracts in parallel within your browser session and downloads individually or as a single ZIP. Useful for archiving a DVD chapter set, batch-extracting podcast source recordings, or pulling audio from a library of legacy MPEG-2 broadcasts.
After editing in Logic or Pro Tools, bounce/export to your delivery format. See AIFF to MP3 for podcast/web delivery, AIFF to WAV for Windows DAW handoff, or AIFF to FLAC for lossless archival at half the size.
