Seán Mac Erlaine · mastering engineer

Make your music stand up and out in the world.

Mastering is a means for me to bring the best of my knowledge to your music. I have been training my ears in the minutiae of music, frequency, noise and quality since my training in my early years and 25+ year career as an instrumentalist.

Today I work with people internationally to bring their music to a finished state where it stands alongside the world's finest. I bring decades of music industry experience to your work and I couple that with a long running passion for analogue equipment, programming and sonic excellence.

Recent mastering industry recognition by way of UK charts top 10, Bandcamp Best Contemporary Classical Music 2025, Mojo Top 10 Folk Albums 2024, #2 Irish Independant Album charts 2024, Bandcamp Best Selling 2024 albums, Bandcamp 'best of' 2022, Four RTÉ Folk awards nominations, The Guardian folk album of the month, international radio playlists, etc.

“Seán is one of the best mastering engineers in Ireland. He was both patient and very skilled in his approach to getting the best out of my mixes. I couldn’t ask for better.”

~ Stephen Shannon (producer, Real World, Domino, Netflix)

“You have absolutely KNOCKED it out of the park Seán. It’s perfect! Amazing job thank you so much! Whatever black magic you are working up there is a fine spell! If you need any mastering done, Seán is a safe pair of ears."

~ Richie Egan / Jape

“Seán has been a joy to work with - he's quick, insightful, and precise in all the right ways. He's great at providing and absorbing feedback, and admirably focused on quality and consistency."

~ Winter Aid / Shane Culloty (San Francisco-based viral sad song sensation)

It's so reassuring to work with someone so mistakefree and fussfree as Seán. If we were sculptors Seán would be the master polisher, he'd make your work sell in the exhibition.”

~ Rónán Ó Snodaigh (Kila)

"His meticulous approach to mastering has elevated the sound of my albums to new heights, bringing out the subtle nuances and textures that make the music truly come alive. Seán is a rare and invaluable gem in the world of audio mastering."

~ Myles O'Reilly (Arbutus Yarns, filmmaker, musician)

“Seán has mastered a few projects for me now, all completely different styles, and I've been delighted with each. He has a fantastic ability to add the final glue needed to make an album feel whole and consistent. It's been wonderful to have someone with a true understanding of mastering to be the final ears in the process.”

~ Steve Lynch (composer, BBC, Hulu, Dolby, Beats by Dre)
