2.1.13. Learn source range
The learn source range parameter allows you to enable or disable learning for source range.
While active, source range will be adjusted to accomodate the min and max input loudness. This is useful for quickly setting the source range to match the input loudness. Once the source range is set, you can disable learning to prevent the source range from changing.
Learn accounts for source distribution asymmetries, making it great for hitting a target range accurately.
