    58 For AAC only: (Because it is a little bit confusing, with 3 encoders available)[[BR]] 
     56For AAC-LC: 
    5957{{{

    7270The '''>=''' sign means greater or the same quality.[[BR]] 
    73 Even though AAC should generally give better quality than MP3 at the same bitrates, libmp3lame should give better quality output than `libfaac`.[[BR]] 
    7471This list is just a general guide and there may be cases where a codec listed to the right will perform better than one listed to the left at certain bitrates. [[BR]] 
    7572The highest quality internal/native encoder available in FFmpeg without any external libraries is aac.[[BR]] 
    7673 
    77 Please note it is '''not recommended''' to use `vorbis` for Vorbis encoding; use `libvorbis` instead.[[BR]] 
     74Please note it is '''not recommended''' to use the experimental `vorbis` for Vorbis encoding; use `libvorbis` instead.[[BR]] 
    7875Please note that `wmav1` and `wmav2` don't seem to be able to reach transparency at any given bitrate.[[BR]]

    105102- '''libmp3lame''' Usable range >= 128Kbps. Recommended range '''-aq 2 (>= 192Kbps)'''[[BR]] 
    106103- '''ac3 or eac3''' Usable range >= 160Kbps. Recommended range '''>= 160Kbps'''[[BR]] 
    107 - '''libfaac''' Usable range >= 160Kbps. Recommended range '''-q:a 330 -cutoff 15000 (>= 192Kbps)'''.[[BR]]

    125122---- 
    126123 
    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]] 
     124When compatibility with hardware players doesn't matter then use `libvorbis` in a MKV container when `libfdk_aac` isn't available.[[BR]] 
     125When compatibility with hardware players does matter then use libmp3lame or ac3 in a MP4/MKV container when `libfdk_aac` isn't available.[[BR]] 
    129126Transparency means the encoded audio sounds indistinguishable from the audio in the source file.[[BR]] 
    130127Some 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 efficient than CBR but may not be as hardware-compatible.[[BR]]
