Mastering is the final stage in your music production and highly recommended for any release. 

It’s the icing on the cake; ensuring your track is sonically balanced across all playback systems. 

If you’re releasing an album or EP, online Wav mastering also ensures a consistent, clean sound across all tracks. The 24 bit final master audio can then be duplicated and distributed across various mediums for sale. 

With many singers, songwriters and artists choosing to take an indie approach to making music, not everyone has the budget for big studios and expensive production costs. So, how can you get your tracks mastered to a high quality without breaking the bank?

Well, I have just the answer including free mastering options…

It goes without saying that Abbey Road Studios is one of the most iconic studios in the world. With award-winning audio engineers and a vast catalogue of vintage and state-of-the-art equipment, quality masters are guaranteed.

Our review of Abbey Road Studio

Overall, the whole process was incredibly easy. The Studio’s website is very clear and intuitive to use. Simply upload your track to the Abbey Road website, select a specific mastering engineer and provide any reference tracks or notes to help specify what sound you’re looking for. 

Furthermore, the turnaround was quick thanks to the studio’s 5-day turnaround guarantee. 

In regard to the audio, my opinion is obviously subjective. I listened to the master on multiple devices and speakers in order to give a comprehensive, honest review…

The master, in my opinion, sounds warm and full. It’s created a sonic depth in the track that wasn’t there before. Everything sits well in the mix with levels balanced beautifully. My only possible critique is the amount of low end. 

I personally feel that the master has an almost cluttered lower end that feels almost muddy compared to other masters in this review. 

Ease of Use rating: 5 / 5

Pricing rating: 2 / 5

Audio Quality rating: 3 / 5

Overall Rating (Average): 3.3 / 5

2. BandLab

BandLab has been creating quite a storm with indie musicians, producers and artists over the recent years. 

The service provides a free DAW that allows you to create and collaborate across platforms with unlimited cloud storage. Most interestingly though, they provide a free online mastering studio service to enhance your tracks to the next level. 

With this free online audio mastering service, however, you get what you pay for… In this case, not a lot! 

BandLab, although intuitive to use, doesn’t offer anywhere near the number of features that other services offer in this review. 

Perhaps that makes it ideal for those wanting a simple master without having to mess around with the complicated producer lingo? 

Features offered are limited too: ‘CD-quality audio’, ‘bass boost’ and ‘enhance quality’.

Our review of BandLab

Despite its simplistic service, I am quite impressed with the end result. BandLab’s master has taken our mix and created a well-balanced track with most noticeably an improvement on the crisp tightness of the guitars. 

My only fault with this master is its lack of depth and power. Compared to masters from the top UK studios, BandLab’s feels thin and lifeless compared to that of Abbey Road and Metropolis. 

My overall opinion though is this isn’t too bad! 

This free audio mastering would be ideal for artists on a tight budget or those wanting to up the quality of their tracks for a simple portfolio (session musicians recordings to show off talents etc).

Ease of Use rating: 4 / 5

Pricing rating: 5 / 5

Audio Quality rating: 2 / 5

Overall Rating (Average): 3.6 / 5

Our Review of Landr

Landr’s master feels nicely balanced with each instrument cutting through the mix well. There’s a clear warmth to this which I personally like. 

I personally love the low end to this master. It feels warm and clean with lots of depth. Unfortunately, I can’t say the same for the top end. 

Sonically, the top end in this master feels thin and lifeless. If I could take the top mids and highs from BandLab and combine them with the bottom end of Landr’s master, I’d be very happy. 

Regarding the service and its user experience, I don’t really have a lot to say – Simple and to the point!

Like BandLab, features are extremely limited, Landr only allows you to select the intensity of your master – A real shame considering the subscription fees and additional charges to...
