    en.wikipedia.org/wiki/Transparency_(data...

    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, when encoded as VBR MP3 (corresponding to the -V3 and -V0 settings of the highly popular LAME MP3 encoder). [1]

    Linear pulse-code modulation (LPCM, generally only described as PCM) is the format for uncompressed audio in media files and it is also the standard for CD-DA; note that in computers, LPCM is usually stored in container formats such as WAV, AIFF, or AU, or as raw audio format, although not technically necessary.

    Encoding is limited to constant bit rate (CBR) and up to 20 kbit/s. The first and only version of the codec is WMA 9 Voice. Windows Mobile-powered devices with Windows Media Player 10 Mobile have native support for WMA 9 Voice playback. [30] In addition, BBC World Service has employed WMA Voice for its Internet radio streaming service. [49]

  9. MP3 - Wikipedia

    en.wikipedia.org/wiki/MP3

    The n.nnn quality parameter (-V) is documented at lame.sourceforge.net but is only supported in LAME with the new style VBR variable bit rate quality selector—not average bit rate (ABR). A sample rate of 44.1 kHz is commonly used for music reproduction because this is also used for CD audio , the main source used for creating MP3 files.
