Hi, I'm James, an audio engineer.
I started out as a musician wanting to make my own records.
The decision to study led to me obtaining an Advanced Diploma of Sound Production, which has given me a solid foundation of knowledge and practice to be able to create professional-level audio.
Since my graduation in 2016, I have been working with a host of artists locally and remotely in many different genres including ambient, electro-acoustic, trip-hop, death metal, and many forms of rock and electronic music.
My work involves not just mixing tracks to the utmost quality but also working closely with artists and helping to develop their ideas. I love translating these ideas into reality through writing and performing both arrangements and new parts, to bring the best out of any song.
Should you require services such as general editing like vocal comping, auto tune/melodyne, drum editing, mixing or producing, even a mix of all of the above, I would love to hear from you.
Please contact me to discuss budgets and rates. I understand that every project is different and budgets can be limited, and therefore believe in a degree of flexibility when it comes to bringing your ideas to fruition.
If you would like to hear my work, you can listen to my portfolio or contact me for further examples.
Let’s make awesome music.
