WAV vs AIFF
WAV and AIFF are audio containers often used for PCM, but either can hold different encodings. The extension alone does not guarantee quality.
Which format should you choose?
Use the container expected by the receiving tool; agree on codec, sample rate, bit depth, channels, and metadata.
Good fit for WAV
Recording and editing
- Keeping a source recording at a known sample rate and bit depth
Good fit for AIFF
Audio editing and exchange
- Production teams that exchange PCM audio with AIFF-capable tools
Basic information
| Field | WAV | AIFF |
|---|---|---|
| Extension | .wav | .aiff, .aif |
| MIME type | audio/wav | audio/aiff |
| Common uses | Recording and editing | Audio editing and exchange |
| How to open | Open with a media player, DAW, or audio editor and inspect the stream properties. | Open with an AIFF-capable editor or player and check the recipient's software support. |
| Export or convert | For distribution, export to a supported format such as MP3 while keeping the editing original. | For distribution, choose a supported format and retain the editing original separately. |

AIFFKey point 1
WAV is based on RIFF and is widely supported.
More on the differencesKey point 2
AIFF has a distinct container structure and is supported by many audio tools.

Check the actual encoding and audio parameters. Container conversion may avoid lossy encoding when the stream can be copied, but verify metadata and application support.
- Both can store uncompressed PCM, but the formats are not identical.
- Support for metadata and particular encodings varies by application.
Frequently asked questions
Does WAV always sound better than AIFF?
No. When both files carry identical audio data, quality is the same; encoding and settings matter more than the container name.
Does AIFF always sound better than WAV?
No. Compare the actual audio encoding and settings rather than assuming quality from the extension.
