An MPG file is an MPEG-1 or MPEG-2 program stream — a legacy video container whose audio track is almost always MPEG-1 Audio Layer II (MP2), the lossy codec used by Video CD, HDV camcorders, and many PAL DVDs. This converter demultiplexes that program stream, pulls out the audio, and decodes it to WAV — uncompressed linear PCM that opens in any editor, DAW, or sampler without a codec.
One thing to be clear about up front: WAV is a lossless container, not a quality upgrade. If the MPG's audio was compressed at 192 kbps MP2, decoding it to PCM gives you a faithful, edit-ready copy of that 192 kbps audio — it does not reconstruct detail the original lossy encode already discarded. WAV's value here is editability and universal playback, not added fidelity.
MPEG-1 Audio Layer II (the audio inside most MPGs) at a Glance
| Property | Value |
|---|---|
| Standard | ISO/IEC 11172-3 (MPEG-1, 1993); extended by ISO/IEC 13818-3 (MPEG-2, 1995) |
| Type | Lossy, perceptual subband coding |
| Typical bitrate | 32–384 kbit/s (MPEG-1); lower rates added in MPEG-2 |
| Sample rates | 32 / 44.1 / 48 kHz (MPEG-1); 16 / 22.05 / 24 kHz added in MPEG-2 |
| Where it's used | Video CD, Super Video CD, HDV, PAL DVD audio, broadcast contribution feeds |
| Reverse fidelity | Cannot be restored — data removed at encode time is gone for good |
WAV (your output) at a Glance
| Property | Value |
|---|---|
| Container | RIFF, published by IBM and Microsoft in August 1991 |
| Payload | Linear PCM (LPCM) — uncompressed, lossless |
| Common depth / rate | 16-bit @ 44.1 kHz (CD quality); higher depths and rates supported |
| Data rate (16-bit/44.1 kHz stereo) | ~1,411 kbit/s — about 10 MB per minute |
| File-size ceiling | Under 4 GiB (32-bit RIFF size field); ~6.8 hours of CD-quality stereo |
| Plays in | Any media player, DAW, editor, or sampler without an external codec |
How to Convert MPG to WAV
- Upload Your MPG File: Drag and drop your
.mpgor.mpegfile onto the page, or click "+ Add Files" to browse. Several files can be queued together. - Set Audio Sample Rate: Leave "Audio Sample Rate" on ORIGINAL to keep the source rate exactly, or pick a target rate (for example 44.1 kHz) if your project needs a fixed one.
- Choose Audio Channel and Trim (Optional): Use "Audio Channel" to keep the original layout or fold down to mono, and use "Trim" to export only a start-to-duration slice instead of the whole track.
- Convert and Download: Click "Convert" to get your WAV file. No sign-up, no watermark.
Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — never shared or made public.
Frequently Asked Questions
Will converting MPG to WAV improve the audio quality?
No. WAV is uncompressed, but it can only preserve what is already in the MPG. The audio inside an MPG is normally MPEG-1 Layer II — a lossy codec — so the WAV is a faithful PCM copy of that lossy track, not a higher-fidelity version of the original recording. You get an editable, codec-free file, not restored detail.
Why is my WAV file so much larger than the MPG's audio?
Because WAV stores raw samples with no compression. CD-quality 16-bit/44.1 kHz stereo PCM runs about 1,411 kbit/s, or roughly 10 MB per minute, regardless of how quiet or simple the audio is. A 5-minute clip lands near 50 MB. If size matters more than edit-readiness, convert to MP3 instead.
What bit depth and sample rate does the output use?
The decoder preserves the source sample rate when "Audio Sample Rate" is left on ORIGINAL, so an MPG carrying 48 kHz audio yields a 48 kHz WAV. The PCM payload is standard signed 16-bit, which every DAW and editor reads. You can downmix to mono with the "Audio Channel" option if you only need a single channel.
Does this keep the video, or only the audio?
Only the audio. MPG to WAV is an extract-and-decode operation: the converter discards the MPEG video stream and writes just the audio track to a WAV file. If you want to keep moving pictures, convert the MPG to a video format instead.
Can I extract just one section instead of the whole track?
Yes. Open Advanced Options and use "Trim" to set a start point and a duration, and only that slice is decoded to WAV. For finer cuts, beat-matching, or stitching several clips, run the WAV through the audio cutter afterward.
Is the resulting WAV safe to import into Pro Tools, Audition, or Audacity?
Yes. The output is RIFF/WAVE with linear PCM, which is the most broadly supported audio container in professional software. In our testing, a 30-second MPG with 48 kHz stereo MP2 audio decoded to a roughly 5.5 MB 16-bit WAV that imported into a DAW with no transcoding prompt.
