    99 The bitrates listed here assume 2-channel stereo and a sample rate of 44.1kHz or 48kHz. Mono may require fewer bits.[[BR]]

    127 When compatibility with hardware players doesn't matter then use `libvorbis` in a MKV container rather than `libfaac` when `libfdk_aac` isn't available[[BR]] 
    128 When compatibility with hardware players does matter then use libmp3lame or ac3 in a MP4/MKV container rather than `libfaac` when `libfdk_aac` isn't available[[BR]] 
     127Some codecs have a more efficient variable bitrate (VBR) mode which optimizes to a given, constant quality level rather than having variable quality at a given, constant bitrate (CBR). The info above is for CBR. VBR is more efficent than CBR but may not be as hardware-compatible.[[BR]]

    129130Transparency means the encoded audio sounds indistinguishable from the audio in the source file.[[BR]]
