Frequently Asked Questions

What MP3 bitrate should I use?

320 kbps for near-CD quality, 256 kbps for excellent quality with good compression, or 192 kbps for a balance of quality and file size.

Will I lose quality?

MP3 is lossy, so some audio data is discarded. At higher bitrates (256-320 kbps), the difference is barely noticeable to most listeners.
