Need help?Convert AVI to WAV Online
Pull the audio out of an AVI video and save it as an uncompressed WAV file. WAV stores linear PCM samples with no lossy compression, so it is the format of choice when you want to edit, master, or archive a soundtrack, dialogue take, or recording that currently lives inside an AVI container. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark.
How to Convert AVI to WAV
- Upload Your AVI File: Drag and drop your
.aviinto the box or click "Add Files" to pick it from your device. You can queue several clips and convert them with the same settings. - Set the Audio Sample Rate: Leave it on Original to keep the source rate, or pick a value from 8000 Hz up to 48000 Hz — choose 44100 HZ for music or 48000 HZ to match video/broadcast audio.
- Pick the Audio Channel: Keep Original, force Stereo for a two-channel mix, or collapse to Mono to halve the file size when the source is voice or a single-channel recording.
- Convert and Download: Click Convert and save your WAV. No sign-up, no watermark.
AVI vs WAV at a Glance
| Property | AVI | WAV |
|---|---|---|
| Type | Video container (RIFF) | Audio container (RIFF) |
| Released | Microsoft, November 1992 | IBM & Microsoft, 1991 |
| Carries | Video + one or more audio streams | Audio only (usually linear PCM) |
| Audio inside | Can be PCM, MP3, AC3, and more | Almost always uncompressed PCM |
| Compression | Depends on codecs used | None in the standard PCM case |
| Max file size | ~2 GB original; OpenDML (1996) raises it | Under 4 GiB (32-bit size field) |
| Best for | Holding finished video with audio | Editing, mastering, archiving raw audio |
Frequently Asked Questions
Will converting AVI to WAV improve the audio quality?
No — WAV is a lossless target, but it cannot recover detail that was already discarded. If the audio inside your AVI was stored as MP3 or AC3, the WAV is a faithful uncompressed copy of that already-compressed sound, not a restored studio master. You only get true lossless audio when the AVI's internal stream was PCM to begin with.
What sample rate and channel layout should I choose?
Leave both on Original if you just want a clean extraction. Set 44100 HZ for CD-quality music, or 48000 HZ to stay in sync with video and broadcast workflows. Use Stereo for a two-channel mix; switch to Mono for voice, interviews, or any single-channel source to cut the file size roughly in half.
Why is my WAV file so much larger than the AVI?
Uncompressed PCM has a fixed bit budget. A stereo 44.1 kHz 16-bit WAV runs about 10 MB per minute regardless of how quiet or simple the audio is, while the AVI may have stored that same audio in a compressed codec at a fraction of the size. The size jump is expected — it is the cost of storing every sample without compression.
Can I extract just a section instead of the whole soundtrack?
Yes. Open Trim, switch it off Unchanged, then enter a Start time and Duration in seconds (or as HH:MM:SS.sss). The converter writes only that slice to WAV, which is handy for grabbing a single line of dialogue or one passage of music. For repeated cut-and-keep edits, the audio cutter gives you a waveform to work against.
In your testing, how big is a typical AVI-to-WAV result?
In our testing, a 60-second AVI extracted to a 44.1 kHz, 16-bit stereo WAV produced a file of about 10.5 MB, because uncompressed PCM at those settings is a fixed ~176 kB per second. Switching the channel to Mono dropped it to roughly 5.3 MB. If you do not actually need uncompressed audio, AVI to MP3 yields a far smaller file; if the WAV itself is too large to email, WAV to MP3 shrinks it after the fact.
