Line 3: A '''transparency threshold''' is a given value at which transparency is reached. It is commonly used to describe compressed data bitrates. For example, the transparency threshold for MP3 to [[linear PCM]] audio is said to be between 175 and 245 kbit/s, at [[44.1 kHz\|44.1 kHz]], when encoded as [[Variable_bitrate\|VBR]] MP3 (corresponding to the -V3 and -V0 settings of the highly popular [[LAME]] MP3 encoder).<ref name="LAME Recommended Encoder Settings">{{citation \| title = LAME Recommended Encoder Settings ~~\| date =~~ \| publisher = hydrogenaudio ~~\| format =~~ \| url = http://wiki.hydrogenaud.io/index.php?title=LAME ~~\| accessdate =~~ }}</ref> This means that when an MP3 that was encoded at those bitrates is being played back, it is indistinguishable from the original PCM, and the compression is transparent to the listener. ==Determination==
