A Few Words About Bit RatesA Few Words About Bit Rates
• Audio (MP3)
• 32 kbit/s — AM quality
• 96 kbit/s — FM quality
• 128–160 kbit/s — Standard Bitrate quality; difference can sometimes be obvious (e.g. bass quality)
• 192 kbit/s — DAB (Digital Audio Broadcasting) quality. Quickly becoming the new 'standard' bitrate for MP3 music; difference can be heard by few people.
• 224–320 kbit/s — Near CD quality. Sound is nearly
indistinguishable from most CDs.
