Approach
Every project starts with the story.As a Re-recording Mixer and Sound Supervisor, I build clarity, space and emotion into every soundtrack while keeping the workflow structured, allowing creative decisions to remain focused and intentional.To me, audio post-production is about far more than technical precision. It’s about using atmosphere, rhythm and emotion to serve the story.During the mix, I focus on how dialogue sits, how space is shaped and how dynamics support the performances on screen. The goal is always to create mixes that feel clear, immersive and emotionally connected to the picture.I keep workflows organised and efficient so the technical process remains predictable, leaving room for confident creative decisions.Collaboration is central to my approach. I work closely with directors, producers and post-production teams to develop a clear sonic vision while maintaining a calm, efficient and enjoyable working environment throughout the mix.

What clients say
"Alex is definitely one of the best I’ve worked with. His technical knowledge is incredible - the enhancement he brings to the viewers listening experience is amazing. He also seems to be able to clean up the roughest of sound. He is also immensely creative,enthusiastic and adds to any production. He really is very very good, and I totally endorse him."
Ollie Parsons - Director
"I have worked with Alex on different series since his days in Hackenbacker on Robozuna and again on my current Netflix series HDR Dolby Atmos.For the current show he worked collaboratively with the Director to set a style and tone which is contemporary and dynamic and makes the most out of Dolby Atmos while remaining in keeping with the creative vision.Alex is a true professional, his attention to detail and communication is second to none and he is frequently ahead of the scheduling curve which makes working with him stress free and reliable. To top it off, he is a lovely guy and a real pleasure to work with."
Alex Cameron, Animation Producer
"I worked with Alexander on the Studio Killers 404 pilot. Because the pilot is based on a musical group the sound design and mixing were of huge importance to get just right. And Alexander knocked the ball out of the park. Everything came together wonderfully and became even bigger and better than we ever hoped and dreamed. I highly recommend Alexander to anyone looking to elevate their projects sound."
