Learning how to master your tracks is extremely time-consuming and finding the cash to pay for an audio engineer is difficult when you’ve got (one hundred) other things you need to spend your money on. You’re already hustling independently and finding creative ways to get your music heard, from promotion to securing live bookings. Time and budget are valuable, especially when you’re starting out.

Following the advancement in technology in the music industry, there has been an evolution in algorithmic online mastering tools and services. We compiled a list of our preferred online mastering tools that are easy to use and budget-friendly.

Before your song is ready to be mastered, you will need to make sure it’s properly prepared. Our friends at Masterchannel broke it down into 3 easy steps on how to prepare your music for mastering.

1. Masterchannel

Masterchannel was co-founded by the superstar DJ Tom “Matoma” Stræte Lagergren – himself one of the most popular producers in the world, with over three billion streams amassed of his tracks – alongside German Mastering Engineer and Audio Researcher Simon Hestermann and Norwegian serial entrepreneur Christian Ringstad Schultz. The three share a burning desire to be a positive change in the music industry, so they joined forces to create their automated online mastering solution: Masterchannel!

Masterchannel aims to democratize the mastering process, offering a premium service at an affordable price, and per track instead of a subscription. This flexibility was designed for smaller labels with limited recording budgets, and to open up opportunities for independent artists to supply studio-level sound enhancement in earlier demo versions of their tracks.


Key features

Other AI-driven products on the market compare the tracks users upload to existing songs and genres, but Masterchannel took a different approach. Instead, their unique algorithm mimics the thought processes of a human mastering engineer to deliver an impressive result.

4. eMastered


eMastered is an online automated mastering service that uses artificial intelligence to master tracks. The service was co-founded by Grammy Award-winning engineer Smith Carlson and hit EDM singer/producer Collin McLoughlin to create a mastered product that meets professional standards.

You can upload your song to their platform (in MP3, WAV, or AIFF) and have it mastered in seconds using their AI-powered mastering engine. Their algorithm is built on automation and will analyze your song to choose the best tools that will help enhance your track so it sounds like eMastered says, “more full of life”.

It’s not 100% automated, with some control over the intensity of several aspects like EQ, compression, volume, stereo width, and the overall "strength" of the master. There's also a simple 3-band EQ (Low, Mid, High) that you can boost/cut to your liking for each recording.

eMastered uses machine learning to improve each song it masters and is compatible with any genre. The premise of their service is to use traditional mastering techniques in an automated format.

Key features

  • You get a quality-sounding master regardless of genre. 
  • Reference mastering. You can upload a reference track to be analyzed by the system. It then applies effects to your song in order to create a sound that is similar to the reference.
  • Advanced options/customizability. Allow for manual control of compression, EQ, and other factors so that the AI isn't performing all of the jobs without any help from the user.
  • Cloud storage. All of your masters should be backed up on the eMastered server.
  • One subscription plan which unlocks unlimited masters and downloads.



eMastered has one plan that you can pay for in three different ways. Upon subscribing, you get unlimited access to their mastering tools and downloads. Additionally, you get access to their reference mastering, shareable library page, cloud storage, and track statistics. 

Here are the three payment options for their plan. 

  • Yearly (billed monthly) at $24 per month. A one-year commitment is required with this plan.
  • Yearly at $14 per month. ($168 billed upfront).
  • Monthly (billed monthly) at $49 per month (you can cancel anytime).

Tip: If you want to get free months of unlimited mastering, eMastered has a referral program. Read about their offer here.


☑️ Affordable pricing
☑️ Several mastering settings that you can easily adjust
☑️ Quick turnaround and easy to use
☑️ Sonically it fills the complete frequency spectrum
☑️ Master your song using a reference track
☑️ Share your finished track with your fans


❌ The mastered track lacks a little magic that you get when you employ a dedicated mastering studio
