They say that the MP3 format "flattens" out the dynamics - the differences in pitch and volume - in a song. In addition, some musicians and audio engineers say that the MP3 format is changing the way music studios mix recordings. In a way, the music industry is returning to its roots - the music single is becoming popular after nearly dying out during the CD era. With music services like Amazon and eMusic, customers can buy music by the song. There's no denying that, quality issues aside, the MP3 format is changing music.

But other people argue that it's impossible for the human ear to detect the difference between an uncompressed CD file and an MP3 encoded with a 320 Kbps bit rate. They argue that even at the highest bit rate settings, MP3 files are inferior to CDs and vinyl records. Some audiophiles - people who seek out the best ways to experience music - look down on the MP3 format. Many music sites and blogs urge people to use a bit rate of 160 Kbps or higher if they want the MP3 file to have the same sound quality as a CD. Using a bit rate of 128 Kbps usually results in a sound quality equivalent to what you'd hear on the radio. Bit rates range from 96 to 320 kilobits per second (Kbps). The lower the bit rate, the more information the encoder will discard when compressing the file.

Most MP3 encoding software allows the user to select the bit rate when converting files into the MP3 format. It's "perceptual" partly because the MP3 format uses characteristics of the human ear to design the compression algorithm. To make a good compression algorithm for sound, a technique called perceptual noise shaping is used. So we're familiar with compression algorithms for images and words and we know they work. Is it possible to compress a song without hurting its quality? We use compression algorithms for images all the time.
#Kbps audio quality download
This lets you download a song much more quickly, and store hundreds of songs on your computer's hard disk. With MP3, a 32-megabyte song on a CD compresses down to about 3 MB. The goal of using MP3 is to compress a CD-quality song by a factor of 10 to 14 without noticeably affecting the CD-quality sound. The MP3 format is a compression system for music. Over a 56K dial-up modem, it would take close to two hours. Even with a high-speed cable or DSL modem, it can take several minutes to download just one song. If an average song is three minutes long, then the average song on a CD consumes about 32 million bytes (or 32 megabytes) of space. Let's break that down: 1.4 million bits per second equals 176,000 bytes per second.
