Mastering is a very important stage in music production. Without mastering, the tracks would sound dull, or at best, like a noisy hot mess.

All you have to do is to upload your track and then wait for it to be mastered by Majordecibel’s servers, a process which takes only a few minutes. The tracks are mastered using various techniques including stereo-linked multiband compression, linear phase equalization, bass, and sub-bass enhancement, stereo enhancement and gain and limiting to widen the sound stage.

Majordecibel’s mastering produces a signature sound based on how the process has been tuned and developed. When using Majordecibel, it is important to export your tracks when they are in WAV form, which allows the platform to deliver masters of the highest quality possible.

It is also important to avoid performing excessive dynamic processing on your tracks when using Majordecibel to master your tracks. Majordecibel also does not provide any active noise reduction techniques so it is important to upload your best recordings for the user to get optimal results.

Majordecibel provides three mastering options; Low, Medium and High. With High, some of the dynamic range is sacrifices to favor a sound which is punchier and louder. Low works to preserve more dynamic range and work well in the loudness. These three mastering options are available to all users.

Final Thoughts

Online mastering platforms do a good job improving the quality of a track. The master tracks much faster than when the same tracks are mastered by human mastering engineers. They have also managed to make mastering available to many artists.

These platforms also offer a cheaper alternative for mastering compared to human mastering engineers who are much more expensive.

Mastering platforms, however, have a lot of catching up to do since experienced human mastering engineers still produce tracks which are of much better quality. These platforms should carry out frequent platforms to improve the quality of the masters they produce.

I would suggest you use one of these online mastering platforms to master your tracks if you cannot afford a human mastering engineer or if you are short of time. However, if you can comfortably afford an experienced mastering engineer, you should master your tracks with them.

Pro Tip: The Best Alternative to Online Mastering Services

eMastered, Landr, Cloudbounce are great, but they can be quite expensive after a few months

That’s why I strongly recommend you take a look at Ozone by Izotope. Just like online mastering platforms, it includes a one-click instant and automated mastering process that provides you an easy and fast mastered version of your track (with many juicy extra features).

But the huge difference is that you pay only once and you are set for life!

Of course, it’s more expensive that 1 month of subscription with an online platform, but in my opinion it’s definitely worth the price if you are interested to learn the basics of the tool.

That’s now what I use everyday in my workflow instead of eMastered or Landr, and I am so glad I made the change. With Ozone I saved hundreds of dollars and gained a great amount of creative freedom with my masters, so don’t hesitate to check it out!
