Frequently Asked Questions

Is 320kbps the highest MP3 quality?

Yes. 320kbps is the maximum constant bitrate (CBR) for MP3. For higher quality, use lossless formats like FLAC or WAV. Most listeners can't distinguish 320kbps MP3 from lossless in blind tests.

Why is the 320kbps file larger than 128kbps?

Higher bitrate = more data per second = larger file. A 2-minute file at 320kbps is ~5MB vs ~2MB at 128kbps. The quality difference is most noticeable in complex music with cymbals, strings, and spatial effects.
