Choosing the right audio format affects both sound quality and file size. Whether you're a music lover, podcaster, or audio professional, understanding the differences is essential.
MP3 — Small Files, Good Quality

**File size:** ~3MB per minute (320kbps)
**Quality:** Good to excellent

FLAC — Lossless Compression
FLAC compresses audio without any quality loss. Files are about 50-60% the size of WAV while maintaining bit-perfect reproduction.
**File size:** ~15MB per minute
**Quality:** Perfect (lossless)
**Compatibility:** Good (most modern players)
**Best for:** Music archiving, audiophile listening

WAV stores raw, uncompressed audio data. It's the standard for professional audio production but produces very large files.
