Serious Business

What I love about the QB team is their dedication to get things to the next level. I’ve had the privilege to work with them and each time they’ve been professional, offering creative insight into their decisions and just…thoughtful. It’s been a blast working with Qb Sound studio.


These guys have been reliable and high quality on every project to date! Definitely recommend.

Anton is one of the most talented guys I’ve had the pleasure of meeting online.
Your work is incredible and impeccable. I was lucky to collaborate with him on some projects because his songs and sound effects always make the level of the work go up.
