The highest quality MP3 bitrate is 320 kbps at 16 bit. You can encode MP3s as low as 96 kbps. MP3s use a compression codec that removes frequencies while trying to preserve as much of the original recording as possible. This does result in a reduction in sound quality but also a big reduction in file size.

Which is better 128kbps or 320Kbps MP3?

The lower the Kbps, the more data the encoder will eliminate when compressing an audio file; the range for bit rates is from 96 to 320 Kbps. 128 Kbps quality is typically considered radio quality, and a bit rate of 160 or higher is equivalent to CD sound quality. ... To maximize sound quality, 320 Kbps is the best choice.

How many Kbps should an MP3 be?

Audio CD bitrate is always 1,411 kilobits per second (Kbps). The MP3 format can range from around 96 to 320Kbps, and streaming services like Spotify range from around 96 to 160Kbps. High bitrates appeal to audiophiles, but they are not always better.
