Sein Mackay speaking about his passion and drive for great sound.

"The ability to record sound, edit, transform and layer audio has fascinated me most of my life.  I got my first sound recorder at the age of 5 and started performing music at 7.  By age 14 I moved onto PC DAW production and began experimenting with audio and things like modifying an analog multi-track recorder to work as a Theremin and sensor to control MIDI.


Sound inspires, and every sound has its own story.  Hearing is such a huge part of the human experience and I am here to help you with outstanding services because consistent audio is paramount for a great sound experience!"
