What Is a WAV File?
WAV files explained: the uncompressed audio format standard, when to use it, and how it compares to MP3 and FLAC for music production and distribution.
WAV is an uncompressed audio format developed by Microsoft and IBM that stores sound as raw PCM samples. It is the production-standard format for music because it preserves every detail of the recording with no compression loss.
How WAV stores audio
WAV files contain raw pulse-code-modulated (PCM) audio samples plus a small header. Because nothing is compressed away, a WAV is an exact digital copy of the recorded signal.
The trade-off is file size — a stereo 44.1kHz/16-bit WAV is about 10 MB per minute of audio.
WAV in production and delivery
Studios, mastering engineers and distributors use WAV for intermediates and final masters because it is universal and lossless.
For streaming delivery, uploading WAV lets platforms transcode to all their formats from the best possible source. Zaventra Music Group accepts high-resolution WAV masters.
WAV vs FLAC vs MP3
WAV is uncompressed (largest), FLAC is lossless-compressed (same quality, half the size), and MP3 is lossy (smallest, reduced quality).
Use WAV or FLAC for your archive and distribution masters, and MP3 only for convenience copies.
Key Points
- Uncompressed PCM audio format
- Universal production standard
- Large file sizes
- Best source for distribution
Frequently Asked Questions
Is WAV better than MP3?
For quality, yes — WAV contains the full recording while MP3 discards data. MP3 is smaller, which suits casual listening.
Can I convert MP3 to WAV?
Technically yes, but you cannot restore the data MP3 removed. Converting a lossy file never improves its quality.
What WAV settings should I deliver?
24-bit/44.1kHz or higher is the distribution standard for music masters.
