What Is WAV? A Complete Guide to the WAV Audio Format

WAV is a container based on the RIFF (Resource Interchange File Format) specification. In almost all cases it holds linear PCM (pulse-code modulation) audio: each sample is stored exactly as captured, with no compression. Because there is no encoding stage, WAV files are bit-perfect and place almost no load on the CPU during playback or editing- One reason digital audio workstations default to them. The header technically allows compressed payloads via a format code, but in practice every application assumes a .wav file is PCM. A professional extension, Broadcast WAV (BWF), adds timecode and origin metadata for radio and film workflows while remaining an ordinary WAV to normal players.

CD-quality WAV is 16-bit / 44.1 kHz stereo, which works out to 1,411 kbps- Roughly 10 MB per minute. Studio work commonly uses 24-bit depth and sample rates of 48, 96, or 192 kHz, which grows files further. The RIFF structure imposes a 4 GB size ceiling, and metadata support is limited compared with formats like MP3 with ID3 tags: WAV INFO chunks exist but are inconsistently read by players.

Use WAV whenever audio will be edited, processed, or archived at full quality: multitrack recording, mixing and mastering, sound design, broadcast delivery, and audio destined for video post-production. Because every edit and export stays lossless, WAV avoids the generational quality loss that repeated lossy encoding causes. For everyday listening and sharing, however, its size is overkill- Our MP3 vs WAV guide walks through the trade-off. WAV is also the standard deliverable for mastering engineers and for uploading final mixes to music distributors, most of which ask for 16-bit or 24-bit WAV at 44.1 kHz.

WAV enjoys near-universal support on Windows, macOS, Linux, iOS, and Android, and in every serious audio application. The practical obstacles are size-related: WAV files are slow to upload, quickly fill phone storage, and are rejected by many messaging apps and email attachment limits. Browsers can play WAV directly, which suits short interface sounds, but it is a wasteful way to deliver full-length songs over the web.

To shrink a WAV for sharing, use the WAV to MP3 converter- A 320 kbps MP3 keeps excellent quality at under a quarter of the size, and 320 kbps is a good default for music. If an application demands WAV input, the MP3 to WAV converter repackages your MP3 as PCM (the file gets bigger, but lost detail is not restored). After converting you can normalize loudness or trim the track in the same workflow.
