During these surreal and crazy times that we are currently living in, I really hope that you and your family are safe.
This is not an easy time for any of us and everyone will have to adjust to a different way of living.
Much like yourselves, here at Swift Mastering we are closely following the impact that the coronavirus (COVID-19) is having on our local communities, small businesses and in particular the music industry.
It is very sad to hear how this virus outbreak is threatening the livelihood of many of our fellow colleagues and perhaps it pushes us to reflect on how fragile our society really is. Difficult times lie ahead of us and there will be tough choices to be made.
But…. we all need to do our bit in order to contain and defeat this virus, so we have decided to shut our London studio until further notice. That means that all our music production and mixing work in our London studio has now been been put to an immediate halt.
However, a silver lining…as many of you will know already, since 2019 we have moved all our mastering operations to our new mastering suite up in the North Yorkshire countryside. For the past 14 months we have worked solely on an online basis. Therefore, even during these trying times,

we want to reassure all our customers that we are be able to keep all our online mastering (and mixing) operations 100% undisrupted.

Stay safe, all the best.

  • Intro

    Since its opening in 2004, we have served both chart-toppers and independent musicians.

     We were one of the first mastering studios in the UK to offer “online mastering” services. Over the last 15 years, we have been continually tweaking and refining our online mastering workflow achieving five stars feedback from both Google and Facebook and by providing services such as iNTouch Mastering.

     We do not offer attended sessions.

    Although we are blessed enough to own some of the finest equipment on the market, what we really pride ourselves on, is the attention to detail we give to all projects (big or small). While you work with us, we will always try to make you feel reassured that your music is in safe hands by establishing excellent communication channels (and yes, you can always reach us at any time!)

Why Choosing Us?

    • We Are Good!

      Ok, you wouldn’t expect us to say anything less would you? 😉 But simply put, you will find very few other mastering studios in the world offering the quality we provide regardless of the price.

    • We Are Honest and Transparent

      Although in today’s economy this is as rare as a pink Unicorn, we do not have hidden charges lurking around and we DO NOT undertake ANY job if we are not 100% sure we can deliver it on time or if, in our opinion, the project is yet not ready to be mastered.

    • We Love What We Do!

      Ok, this might sounds obvious…but after all these years, we are still über-passionate about making artist sounding the best they possibly can!

    • We Are Respectful

      We understand perfectly that not everyone can be top charters! We understand that even the biggest musical genius had to start from somewhere. So, whoever you are, if you make music, you have our respect and you are going to be treated accordingly.

    • We Are Fair On Our Prices

      You can find studios that charges less (even a lot less) but you’ll also find studios that charges tenfold what we do. So how did we set our fees? Simply put, we earn enough to make a living. We don’t believe undercutting out competitors by setting out rates super low or overcharging our clients by abusing their trust, is either good or smart in the long run.
      Our rates represent what we believe to be an honest hourly rate that reflects the quality of the services we offer and the professionalism applied to every project we undertake.

    • We Are Still Learning

      Doesn’t matter who you are, the day that you think you know it all, is the day that you should retire. Learning is a big part of becoming successful and we are humble enough to admit, that from time to time, things could have been dealt differently. BUT, we always have shown the will to learn and not to commi the same mistake again. THIS IS WHY, IN THE LAST 5 YEARS, 100% OF OUR PAST CLIENTS WHERE COMPLETELY SATISFIED OF THE SERVICE THEY RECEIVED! And no, we did not make this one up!
