WAV to FLAC FAQ
Common questions about converting WAV to FLAC.
No. FLAC is mathematically lossless, meaning the audio data is identical to the original WAV. When you play a FLAC file, it decodes to the exact same audio as the original WAV.
FLAC typically achieves 50-70% compression, so a 100MB WAV file becomes 30-50MB as FLAC. The exact ratio depends on the audio content - simple recordings compress more than complex ones.
Some professional audio software works better with WAV, and WAV has slightly faster load times since no decompression is needed. For archiving and playback, FLAC is generally better.
No. All FLAC compression levels (0-8) produce identical audio quality. Higher levels just use more CPU time during encoding to achieve smaller files.
Yes, absolutely. Converting FLAC to WAV produces a file that is bit-for-bit identical to the original WAV. This is the beauty of lossless compression.
