This algorithm can target IL, LRA, and maximum true peak. This algorithm can target IL, LRA, and maximum true peak. To accurately detect true peaks,
the audio stream will be upsampled to 192 kHz unless the normalization mode is linear.
To accurately detect true peaks, the audio stream will be upsampled to 192 kHz. Use the @code{-ar} option or @code{aresample} filter to explicitly set an output sample rate.
