Therefore, every second in a 192 kbps MP3 contains 192 kilobits (24 bytes) of data. The higher the bit rate, the more information the MP3 contains; The more information it contains, the quality is closer to the original audio recording. The bit rate also determines the size of the MP3 file: a four-minute song encoded at 128 kbps occupies a little more than 3.5 MB, while the same song encoded at 320 kbps requires more than 9 MB of space.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Choice_of_a_bit_rate\"><\/span>Choice of a bit rate<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>When you convert a sound file or extract your CD collection to MP3, you must specify the bit rate you want the encoder to use. Choose a bit rate based on the type of audio you are encoding and on your desired purpose. If you are converting a conference or other piece of vocal audio, a bit rate of 128 kbps is more than enough. If you are encoding MP3 files for use with a portable media player, a bit rate of 192 kbps usually provides a good balance between audio quality and file size. If you are converting your CD collection to MP3 for archiving, encode the files with a bit rate of 320 kbps.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Variable_bit_rate\"><\/span>Variable bit rate<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Coding with a variable bit rate changes the bit rate of the MP3 depending on the type of data present at a certain point in the audio. For example, a variable bit rate encoder could encode a portion of dense information from an MP3 at 320 kbps; however, when the audio contains a silent section the encoder lowers the bit rate to 32 kbps. If the bit rate of an MP3 has an unusual number (for example, 204 kbps), this indicates that the creator of the MP3 encoded it with a variable bit rate.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Bit_Rate_Conversion\"><\/span>Bit Rate Conversion<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Although most MP3 conversion and encoding programs can modify an MP3 at a different bit rate, this is not a good idea, generally speaking. Converting an MP3 to a higher bit rate does not add audio information to the file, so the sound quality does not increase. Converting an MP3 to a lower bit rate reduces the file size, but it could also introduce audio defects, since the encoder is compressing a file that is already compressed. If you need an MP3 file to have a different bit rate, re-encode an MP3 from the original audio CD or WAV file.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What is the normal bit rate in an MP3?
