"I discovered Katie and her mastering service through my mixing engineer Elliot Vaughan. He highly recommended her, at the time I was considering some of the more well known studios who proved to be very inflexible and added significant costs for every little addition, such as formatting the masters as A/B audio files for vinyl, providing a DDP image etc and doing tweaks and revisions. 

I agreed to try Katie and the results speak for themselves. Her and Elliot ping-pong'ed the tacks between them and gave my album so much more attention and love than it would have received at one of the bigger studios and for a fraction of the cost. The sonics of the record we have created have far surpassed my original vision and that's due mostly to both Elliot and Katie's skills, perfectionism and professionalism. 

The masters turned out fantastic and Katie has added the final dusting to this record, maintaining the integrity of what I was trying to do and generally enhancing the listening experience and sonics of this record. I would highly recommend her."

"When I go to Katie for mastering I know that I have zero worries about how the record is going to turn out. It’s refreshing to know my mixes will always come back as a better version of themselves. That’s what I want from Mastering and Katie delivers every time. 

On the odd occasion where small (they’re always small) tweaks are needed, Katie is ready and willing to make sure everyone is happy. She provides a service that is worth 10x the price and it truly annoys me if I have to go anywhere else. 

On top of all the great audio, she’s just really fantastic to work with. A genuinely good human who is generous with her time and her knowledge. She loves what she does and that is contagious. 

The best. 5 Stars"

Andy Davies 

"When producing the new All Tied Up EP, I wanted to find a British mastering engineer that was in-touch with the underground rock scene – someone who really gets what we were trying to achieve on the record. After coming across Katie a few times on Facebook audio engineering groups and discovering that she was the mastering engineer behind the excellent Sonic Boom Six records, I knew she’d be a good fit for the project and I wasn’t disappointed! She instantly grasped the direction we were going for and was able to take the production the final 10% of the way from my mixes to enormous, open, hard-hitting masters. Turnaround was extremely fast, she’s easy to communicate and engage with, was very accommodating with mine and the band’s revision requests and is amazing value for money; I personally think she sells herself very short with the quality she delivers... 

Been a pleasure working with you; hope to work together again on many future projects!"

All Tied Up 

"We went to Katie as we wanted to be able to take our EP "Breaking Silence" to the next level sonically (something which we had previously been unable to do ourselves), and after checking out her work we knew we would be in more than safe hands. 

Katie was an absolute pleasure to work with - even though there are 4 very strong personalities within the band, she totally understood our vision and has breathed life into our work with her extraordinary mastering skills 

Katie's abilities and skill defy her budget friendly pricing and we absolutely cannot wait to work alongside her again on future releases 

Thank you SO much Katie - and here's to the future!"

- All Tied Up 


"I am so glad I chose Katie to master my record; she was a delight to work with, I am extremely happy with the result, and would hire her again in a heartbeat. She was patient, communicative and meticulous, and the mastering process felt much more mutual and interactive than with any engineer I've previously worked with, giving a real shine and balance to the album. I can't emphasise enough how great she is!"

"I have worked with Katie professionally for over 5 years now, most recently on my classical-contemporary album 'Changing Stations'. 

I'd known Katie had worked on an array of diverse recording projects, ranging from acoustic singer songwriters to full bands, classical musicians to contemporary and modern art projects across the world. With this in mind, I was keen to have her on board for the audio engineering of my album. She has a wealth of knowledge in the recording world; along with added experience of musical performance, writing and production. I was impressed by her ability to think outside the box and to be able to collaborate; providing suggestions to enchance the sound and stylistic feel of the project. The advice and care Katie had for my album enabled me to be able to sit back and relax, knowing the mastering was in very capable (and talented!) hands."

James Routh / Sonic Boom Six 

"Since 2012, Katie has been my 'go to' mastering engineer. From demos to full scale commercial album productions, she understands the final product and produces great sounding, professional results. The turn around of work is quick and efficient, and she has often offered constructive, simple feedback which has improved the standard of my mixing."

- James Routh, Sonic Boom Six

Eric Openshaw 

"I recently had the pleasure of having Katie Tavini as a guest speaker for my classes at Broadview Entertainment Arts University in Salt Lake City, and was impressed by her careful consideration when interacting with my students. Finding ingenious ways of demonstrating real world audio engineering scenarios, Katie made the class feel welcome, and comfortable, while still teaching necessary material in a personable, and concise way. Katie is passionate about audio engineering and has a determination to get anyone with a willingness to learn the necessary skills to be successful, while encouraging the same excitement that she has toward the skill set."

Bill Leader 

"I have worked with Katie on several recording sessions over the last two years and I have been consistantly impressed with her reliability, and the skill and insight she brings to both recording and mixing sessions. Her enthusiastic and pleasant demeanour and willingness to get stuck into whatever task is to hand enables her to function in a recording project at a high level."

- Bill Leader, Limefield Studio

Haydn Dickenson 

"Having worked with Katie Tavini on a number of occasions in the studio, I have found our collaborations both absorbing and inspirational. Katie, whose enthusiasm for all she does is infectious and dynamic, is of course a violinist of high calibre across a broad spectrum of genres. She brings this intense creativity into her work at the mixing desk also, where her work is consistently intuitive, daring and questingly original."
