Line 2: In [[data compression]] and [[psychoacoustics]], '''transparency''' is the result of [[lossy data compression]] accurate enough that the compressed result is [[perception\|perceptually]] indistinguishable from the uncompressed input. In other words, transparent compression has no perceptible [[compression artifact]]s. 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 [[~~Pulse-code~~linear ~~modulation\|~~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 =
