Niamh O'Sullivan on SoundBetter

Creative and passionate mix engineer with a masters degree from Berklee College of Music, Valencia. Taught by Grammy award nominated engineer Dani Castelar, and Grammy award winning engineer Leslie Brathwaite. Worked with artists in the past such as Ugolino, Rachel Angel, Adja Turek, Christian Dias and JNKY.

Originally from Dublin, Niamh moved to Spain in 2021 to complete a masters in production and engineering at Berklee College of Music, Valencia. Soon after graduating, Niamh was offered an internship at the renowned Power Station, New York. She jumped at the offer, and got the opportunity to learn from incredible engineers and help with a broad range of sessions, spanning from animation VO recording to 30 piece orchestra tracking. She also assisted the in-house technicians with repairs and upkeep of equipment across the four studios.
In September 2022, Niamh was invited to attend, in collaboration with We Are Moving the Needle, a week long Mix With The Masters seminar with the Grammy award winning mix engineer, Leslie Brathwaite. The seminar was held in Studios La Fabrique, Saint-Remy-de-Provence, France, where Niamh got to fine tune her mixing skills with the guidance of one of the best mixers in the world.
Straight after finishing up in Power Station, Niamh moved to London and was thrilled to join the Miloco team in March 2023. She's been quickly learning the ropes of all of Milocos state of the art studios and has been assistant engineering across a range of projects.

  4. Review by Madi Cox

    I have worked with Niamh on several jobs and she is an amazing mixing and studio engineer. She had quick turn around time between mixes and was very responsive and communicative when giving feedback. After a couple rounds of mixing I had an incredible track that I am so excited to release into the world! She is one of the most kind and professional people I have worked with remotely and in the studio. Can’t wait to work with her again!
