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.
