About A little backstory

Supple 9 started out as a small mixing, mastering and film-sound studio run by Alex Leonard.

In 2018, Supple 9 branched out and started a small boutique record label with a focus on lovingly produced electronic releases backed by a physical format.

If you have any questions at all, please don't hesitate to get in touch.

About Alex

After orchestral and choral involvement at a young age, Alex studied music at the Dublin Institute of Technology before getting drawn towards the technical side of things. After completing his music studies, he studied Sound Engineering and Music Technology at the Sound Training Centre in Temple Bar.

Since completing his training he has been heavily involved in a wide variety of music-related activities. He has worked extensively in film sound editing, mixing, design and composition; theatre sound and experimental art installations; studio production of his own electronic output as Ebauche; mixing and mastering of numerous electronic and non-electronic artists; and even as a vocalist in a fusion-bluegrass band in Cambodia.


We believe that it's not the tools that matter, but what you do with them. In this world an audio engineer's most important tools are their ears, their intuition and their experience.
