Shirty Mastering was founded by Josh Shirt

Josh “Shirty” Shirt is a professional mastering engineer, sound engineer and music producer with over 17 years studio experience, working extensively in the realm of commercial music production, as well as radio jingle recording and production, club DJing, and live music sound engineering.

Josh is an expert at taking vague ideas and turning them into fully produced and mastered tracks. His in-depth knowledge of audio production means he can help artists focus on where and how to improve their sound.

Originally from the UK, Josh has had his music blogged, played on BBC Radio and used on numerous commercials. UK supermarket giant ASDA (the Walmart group) used his library music for their summer advertising campaign and Ryanair used his music on their national UK radio commercials.

Josh founded Shirty Mastering in 2019. To see some of our successes so far, check out our blog and reviews.
