MP3

Use Presets - Medium: This preset VBR should provide near transparency to most people on most music. The resulting bitrate should be in the 150-180kbps range, according to music complexity.

Use Presets - Standard: This preset VBR should generally be transparent to most people on most music and is already quite high in quality. The resulting bitrate should be in the 170-210kbps range, according to music complexity.

Use Presets - Extreme: This preset VBR provides slightly higher quality than the "standard" mode. The resulting bitrate should be in the 200-240kbps range, according to music complexity.

Use ABR: An MP3 file that has an average bit rate of 128 kbit/s transfers, on average, 128,000 bits every second. This is a typical setting.
