My machine-learning tools for mastering

Some time ago, I aquired EXPOSE from the Mastering The Mix and some month later, I updated to EXPOSE2, which is an audio quality control application that helps identify issues with your music production. So many tracks get distributed with a poor EQ balance, true peak clipping, over-compression, phase issues, and more. Mastering the Mix wants to catch these issues before it's too late. With EXPOSE 2, delivery of the best listening experience and release can be done with reasonable confidence.


EXPOSE is a stand-alone app where reference tracks and own music productions can be uploaded and analyzed. This concept is good for some reasons, but can become tedious since the process of analysis, optimization and again analysis affords a lot of back and forth between Logic Pro X (or another sequencer) and EXPOSE.


With the recent aquisition of the Komplete 14 (Native Instruments, Berlin), the iZotope 10 mastering tool containing machine-learning algorithms came into my "LakeView Studio". This is a plug-in that integrates into the output channel containing all mastering tools in a single piece of software. The integration into the sequencer as a plug-in has the significant advantage that the workflow is seemless and fast without the need of changing between apps. Therefore, I completely switched to iZotope 10 in the meantime, while the mastering chain still contains some other tools from Mastering the Mix (e.g. LEVELS and MIXROOM). Moreover, iZotope 10 contains all necessary tools (e.g. EQ, adaptive EQ, compressor, maximizer, limiter, stereo imaging etc.) that are needed for mastering in a single and easy to understand GUI (graphical user interface). Once some educating videos available on iZotope's homepage have been digested, you're ready-to-go!


The process of mastering my own music productions prior assistance of machine-learning tools like iZotope 10 was pretty time consuming:

  1. Mixing
  2. Assembly of the mastering effects chain in Logic Pro X
  3. Adjusting the parameters of the individual mastering tools manually
  4. Hearing the results on several different earphones and speaker systems
  5. Repeat line items 3 & 4 several times

This process took me at least 14 days in total with intervals between adjustments and listening phases to keep the ears "neutral".


Now, since using iZotope 10, this process is shortened tramendously - within 1-2 hours only, the results sound so much better then using the old / tedious and manual process, this is really AMAZING! And the good thing is - all parameters can still be manipulated manually and be adjusted to your personal "taste" so that your sound is remaining your own. Most striking for me is that the mastered files are sounding equally good on all different loud speaker and earphones that I've tested (please refer to the list of studio equipment for details). This benefit can't be rated high enough since it normally differentiates between semi- and professional recordings from each other. 


Additionally, I recently aquired Nectar 3 to mastering my vocal tracks based upon machine-learning algorithms. In practice, it turned out that Nectar 3 is easy to use and manage once you learned how to use iZotope 10 already. The results of the mastered vocal tracks are stunning, the clarity and brightness is noticable even in the final mix, compression and effects are subtle but noticable and every parameter or section can be easily adjusted to the individual taste and preferences. By applying maschine-learning algorithms even the first round of adjustments already provides a significant improvement of the vocal track/s and it's needless to say that Nectar 3 is shortening the mastering process of vocals significantly. Very little to no manual manipulations of the vocals are needed anymore - awesome!



The integration of AI tools within the music mastering process has opened up new avenues of creative exploration and efficiency. Sequencers like Logic Pro X provide a platform for harnessing the power of AI, enabling producers and musicians to achieve professional-quality results with enhanced precision and speed. While AI tools offer valuable insights, time-saving automation, and consistent results, it is important to strike a balance between AI assistance and human creativity. Ultimately, the final judgment and artistic decisions still lie with the musicians and producers. AI tools act as valuable collaborators, augmenting the capabilities of professionals and serving as powerful aids in the pursuit of sonic excellence. As technology continues to advance, the future of music mastering holds exciting possibilities, and the marriage of AI and human creativity is poised to reshape the landscape of music production.
