Frequently Asked Questions
What is FLAC format?
FLAC (Free Lossless Audio Codec) is an open-source lossless compression format. Unlike MP3 or AAC, FLAC preserves 100% of the original audio quality while reducing file size by 30-50%. It's the gold standard for audiophiles and archival purposes.
Will I lose any quality converting WAV to FLAC?
No, FLAC is completely lossless. The audio quality is bit-for-bit identical to the original WAV file. You can convert WAV to FLAC and back to WAV with zero quality loss. The only difference is FLAC files are 30-50% smaller than WAV.
What compression level should I choose?
Level 0 is fastest with less compression (~40% size reduction). Level 5 (default) balances speed and compression (~50% reduction). Level 8 provides maximum compression (~60% reduction) but takes longer. All levels are lossless - higher levels just compress more without affecting quality.
Why use FLAC instead of WAV?
FLAC offers identical audio quality to WAV with 30-50% smaller file sizes. FLAC also supports metadata tags (artist, album, etc.) which WAV handles poorly. For storage, archiving, and lossless music collections, FLAC is superior to WAV in every way except raw simplicity.
Is FLAC compatible with my devices?
FLAC has excellent support on computers, many modern smartphones, dedicated audio players, and streaming devices. However, some older devices and car stereos may not support FLAC. For maximum compatibility with legacy devices, use MP3 or AAC instead.
