UU (Ultimate Utility)

UU is a stock Ableton Live alternative to plugins like REFERENCE or MetricAB

It not only lets you use clean reference track inside your session (without tricky routing) but also: 

• Analyze mid and side information 
• Separate midrange to work on better translation for variety of speakers
• Adjust sub, high and kick & bass details
• Control and compare sub level

...and whichever combination you need since it works both for reference and original track with quick "AB" comparison
