We believe in working with creatives to help develop their process beyond our general services giving ongoing advice across any Audio Production or Engineering projects.



My first time using Bunny’s mastering services, for two analogue masters for a vinyl release, I was not overly confident with one of my mix downs and the mastering results were top class, the masters sounded so much more crisper and solid and really helped clear up the low end I was having issues with. Super quick delivery and gave me feedback for some changes in my mixes , upon which he remastered too, will be using again as my go to mastering services. Thank you mate!

This was my first time ever getting my music mixed and mastered professionally. Bunny definitely impressed me with the quality and the time that it took him to do so. Although the style of music I produce is different to what Bunny personally releases, the song came out exactly how i imagined. Such a smooth process, really shows how knowledgeable, friendly and helpful of a person he is. If I'm ever looking for any mix and mastering services, Bunny is the go-to guy!

I have been working on film & animation projects with Bunny for years now and he is my go to for all things audio. I have had him work as a recordist, foley artist, sound designer and post production mixer. He always happy to consult for me on sound, even when not working the job, and has helped Dont Fret Media develop a standard of audio to match our high quality visuals. Look forward to working with him over the next few months.
