1. Fix your low end with Bass Control

Are you struggling to get your low end to translate across different listening environments? The new Bass Control module is an industry-first tool that solves the major pain point of controlling low-end frequencies. It's an AI-powered tool that lets you easily balance low-end energy, adding drive, punch, and balance to your mix without the guesswork.

2. Restore your dynamics with Unlimiter

Have a mix that's been overly compressed or "squashed"? The new Unlimiter is a groundbreaking, industry-first "undo" button for overly compressed audio. Using cutting-edge machine learning, it can bring back lost transients and transparently revive tracks. Just set the threshold, or click the Learn button, and turn up the missing peaks to restore punch and open up your tracks for easier, cleaner mastering.

3. Fine-tune your mix with Stem EQ

Ever wished you could fix a mix without going back to the mix file? With Stem EQ, you can unlock unprecedented control over your master by separately EQing the vocals, drums, bass, and instruments in your stereo audio file. It's a simple, "feels-like-magic" workflow that gives you the final say over your final balance.
