    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]]
     88- '''libvorbis''' Usable range >= 96Kbps. Recommended range '''-aq 4 (>= 128Kbps)'''[[BR]]
     89- '''libmp3lame''' Usable range >= 128Kbps. Recommended range '''-aq 3 (>= 160Kbps)'''[[BR]]
    9090- '''ac3 or eac3''' Usable range >= 128kbps. Recommended range '''>= 160Kbps'''[[BR]]
    91 - '''libfaac''' Usable range >= 192kbps. Recommended range '''>= 192Kbps'''. Faint artifacts can still be heard on some samples.[[BR]]
     91- '''libfaac''' Usable range >= 192kbps. Recommended range '''-q:a 330 -cutoff 16000 (>= 192Kbps)'''.[[BR]]
     92Example of usage:
     93{{{
     94ffmpeg -i input.wav -c:a libfaac -q:a 330 -cutoff 16000 output.m4a
     95}}}
    9296- '''libtwolame''' Usable range >= 192kbps. Recommended range '''>= 256Kbps'''[[BR]]
    9397
    9498The '''mp2''', '''aac''', '''vorbis''', '''wmav1/wmav2''' and '''libvo_aacenc''' encoders are not worth using.[[BR]]
    9599The '''wmav1/wmav2''' and '''libvo_aacenc''' encoders '''do not reach transparency at any bitrate'''.[[BR]]
    96 The '''mp2''' and '''aac''' encoders can still reach transparency at very high bitrates around '''300Kbps'''.[[BR]]
     100The '''mp2''' and '''aac''' encoders can still reach transparency at very high bitrates around '''300Kbps'''. Use a cutoff of 15000Hz for aac[[BR]]
    97101The '''vorbis''' encoder does not use the bitrate specified in ffmpeg. Most of the times it does sound reasonable, but the bitrate is very high.[[BR]]
