        --tvbr <quality> : encode in True VBR mode, quality=0..127 [default]
        --he             : enable high efficiency (HE-AAC) encoder
                           (cannot be used with True VBR mode)
        --samplerate <auto|keep|value> : control the output samplerate
            auto  : automatically choose the optimum samplerate
                    according to the bitrate and quality [default]
            keep  : keep the original samplerate (if possible)
            value : specify samplerate in Hz; allowed values are

  Quality and speed options
        --fastest : fastest encoding speed, but lowest quality
        --fast    : fast encoding speed, but low quality
        --normal  : moderate speed and quality
        --high    : high quality, but slow encoding speed [default]
        --highest : highest quality, but slowest encoding speed
