Why convert WAV to FLAC?
WAV and FLAC serve different purposes. Converting between them lets you use whichever format works best for your situation.
What is a WAV file?
Waveform Audio File Format: WAV stores audio without any compression. What you hear is exactly what was recorded, with no quality loss. The trade-off is large file sizes, a 3-minute song takes about 30 MB.
Created by: Microsoft and IBM, first released in 1991
Used for: Music production, audio editing, CD-quality masters, sound effects
Technical details: Uncompressed PCM audio. Supports various sample rates and bit depths. A standard CD-quality WAV uses 44.1 kHz, 16-bit stereo.
Compatibility: Plays on virtually every device and audio application.
What is a FLAC file?
Free Lossless Audio Codec: FLAC compresses audio without losing any quality. Think of it as a ZIP file for music. The original audio is perfectly preserved, but files are about half the size of equivalent WAV files.
Created by: Xiph.Org Foundation, first released in 2001
Used for: Music archiving, audiophile collections, lossless streaming, music production backups
Technical details: Lossless compression, so decoded audio is bit-identical to the original. Typically compresses to 50-70% of WAV size. Supports metadata tags and album art.
Compatibility: Supported by most desktop and mobile music players, streaming services (Tidal, Qobuz), and web browsers (Chrome, Firefox).
