What is WAV?
WAV is a container format commonly used to store uncompressed PCM audio for recording, editing, and professional interchange.
WAV technical specifications
WAV is a RIFF-based container, not one codec. That means WAV itself does not have one fixed sample rate, bitrate or bit depth. The values people associate with WAV usually describe PCM stored inside it.
| Property | WAV / WAVE | Common PCM WAV values |
|---|---|---|
| Audio coding | Can identify multiple audio subformats | Linear PCM is by far the most familiar |
| Sample rate | Stored in the format descriptor; not a single WAV-wide fixed limit | 44.1, 48, 88.2, 96, 176.4 and 192 kHz are common; some hardware supports higher |
| Bit depth / sample precision | WAVEFORMATEXTENSIBLE separates valid sample precision from the storage container size | 16-bit and 24-bit integer; 32-bit float is also common in production |
| Channels | WAVEFORMATEXTENSIBLE supports multichannel layouts using a channel mask | Mono, stereo, 5.1 and 7.1 are common examples |
| Bitrate | Depends on the codec or PCM parameters | For PCM: sample rate × bit depth × channel count |
Important: “WAV quality” is therefore not a single specification. A 16-bit/44.1 kHz PCM WAV and a 24-bit/192 kHz PCM WAV are both WAV files, while WAV can also wrap non-PCM audio.
What WAV means
WAV, short for Waveform Audio File Format, is a widely supported audio container. In everyday use, WAV files usually contain uncompressed PCM audio.
That makes WAV simple, predictable, and easy for audio software to process.
Why WAV files are large
WAV files are often large because they usually do not use compression. A CD-quality stereo WAV file stores raw audio data at 16-bit / 44.1 kHz.
Higher sample rates, more channels, and higher bit depth increase file size even further.
When to use WAV
Use WAV when recording, editing, exporting stems, exchanging files with audio software, or preparing audio for further production work.
Use FLAC when you want the same audio preserved in a smaller, better-tagged file for listening or archiving.
WAV vs FLAC
WAV and FLAC can preserve the same audio quality. The difference is storage and workflow. WAV is usually uncompressed and production-friendly. FLAC is compressed losslessly and library-friendly.
Frequently asked questions
Is WAV lossless?
Usually, yes. WAV commonly stores uncompressed PCM audio, which is lossless relative to the source.
Does WAV sound better than FLAC?
No. If both come from the same source, WAV and FLAC should sound identical after decoding.
Why do studios use WAV?
Studios use WAV because it is simple, widely supported, and easy for editing software to process.
Is WAV good for music libraries?
It works, but FLAC is usually better because it saves space and handles metadata more conveniently.
