    1212Transcoding from a lossy format like [[Encoding VBR (Variable Bit Rate) mp3 audio|MP3]], [[AACEncodingGuide|AAC]], Vorbis, Opus, WMA, etc. to the same or different lossy format might degrade the audio quality even if the bitrate stays the same (or higher). This quality degradation might not be audible to you but it might be audible to others.[[BR]]

    165165The bitrates listed here assume 2-channel stereo and a sample rate of 44.1kHz or 48kHz. Mono may require fewer bits.[[BR]]
    166166- '''libopus''' Usable range >= 80Kbps. Recommended range '''>= 128Kbps'''[[BR]]
    167 - '''libfdk_aac default LC-AAC profile.''' Recommended range '''>= 128Kbps''' (http://ffmpeg.org/trac/ffmpeg/wiki/AACEncodingGuide). [[BR]]
     167- '''libfdk_aac default LC-AAC profile.''' Recommended range '''>= 128Kbps'''; see [[Encode/AAC|AAC Encoding Guide]]. [[BR]]
    168168- '''(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]]
    169169- '''(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]]
