01Summary
MP3 is compressed and better suited for sharing and streaming due to smaller file sizes and broader compatibility. While WAV offers superior sound quality, it requires more storage and may not be supported by all devices. MP3 files vary in quality by bitrate, with 320 kbps providing clear audio, though lower bitrates result in noticeable loss.
