    8282Please note that the bitrates listed here assumes the input audio channels is Stereo and the sample rate is >= 44.1Khz. Mono could require less bits.[[BR]]

    84 - '''libopus''' Usable range '''>= 64Kbps'''. Recommended range >= 96Kbps[[BR]]
     84- '''libopus''' Usable range >= 64Kbps. Recommended range '''>= 96Kbps'''[[BR]]
    8585- '''libfdk_aac default LC-AAC profile.''' Recommended range '''(VBR level 3 to 5) or >= 96Kbps CBR''' (http://ffmpeg.org/trac/ffmpeg/wiki/AACEncodingGuide). [[BR]]
    8686- '''(libfdk_aac or libaacplus) -profile:a aac_he_v2''' Usable range '''<= 48Kbps CBR'''. Transparency: Does not reach transparency. Use LC-AAC instead to achieve transparency[[BR]]
    8787- '''(libfdk_aac or libaacplus) -profile:a aac_he''' Usable range '''>= 48Kbps and <= 80Kbps CBR'''. Transparency: Does not reach transparency. Use LC-AAC instead to achieve transparency[[BR]]
    88 - '''libvorbis''' Usable range '''>= 96Kbps'''. Recommended range >= 128Kbps[[BR]]
    89 - '''libmp3lame''' Usable range '''>= 128Kbps'''. Recommended range >= 160Kbps[[BR]]
    90 - '''ac3 or eac3''' Usable range '''>= 128kbps'''. Recommended range >= 160Kbps[[BR]]
    91 - '''libfaac''' Usable range '''>= 192kbps'''. Recommended range >= 192Kbps.[[BR]]
    92 - '''libtwolame''' Usable range '''>= 192kbps'''. Recommended range >= 192Kbps[[BR]]
     88- '''libvorbis''' Usable range >= 96Kbps. Recommended range '''>= 128Kbps'''[[BR]]

    9494The '''mp2''', '''aac''', '''vorbis''', '''wmav1/wmav2''' and '''libvo_aacenc''' encoders are not worth using.[[BR]]
    9595The '''wmav1/wmav2''' and '''libvo_aacenc''' encoders '''do not reach transparency at any bitrate'''.[[BR]]
    9696The '''mp2''' and '''aac''' encoders can still reach transparency at very high bitrates around '''300Kbps'''.[[BR]]
    97 The '''vorbis''' encoder does not use the bitrate specified in ffmpeg. Most of the times it does sound reasonable, but the bitrate is very high.
