Welcome to Hermetech Mastering

My name is Gregg Janman, and I'm an audio engineer and electronic musician based in Japan. I've been mastering audio for about ten years. The name "Hermetech" is a portmanteau word based on the ancient Greek "Hermes", the messenger god of science, and "Techne", which means craft or art. The idea inherent in the name is that audio mastering is a dynamic synthesis between art and science.

I mainly specialise in mastering electronic music, as I am intimately familiar with that genre, but I am very happy to work with any style of music. As a lifelong music lover with wide ranging tastes, and someone who is extremely concerned with sound quality, I give my utmost attention to detail when mastering your lovingly crafted music. 

I spend a long time just listening to your tracks, both before and after processing, to make sure that things don't just sound louder, but also better. To this end I employ a number of tools such as high quality D/A and A/D conversion, analogue compression and equalisation, and digital limiting. After processing the file I will sample rate convert if needed, and dither down to the target format for the final master, which will then be ready for pressing and distribution.

Please feel free to have a browse around the site, and don't hesitate to contact me if you have any questions or comments, would like to hear more examples of my work, or would like me to master a track for you.
