Digital Audio and CD Mastering: sessions are conducted with discrete analog equipment and the shortest audio signal path possible to ensure audio integrity. Before your session, our engineers will discuss your expectations, likes, dislikes and your mixes will be evaluated. This information is then taken into consideration while Infrasonic works to deliver your vision with the best tools available in a precise listening environment. 

Vinyl Mastering: is handled on our vintage Scully LS-76 cutting lathe as well as our original Neumann Lathe with custom RCA electronics. Infrasonic creates masters for 7″s, 10″s, and 12″s at 33 and 45 rpm as well as dub plates (reference acetates) for DJs and as a pre-plating test master. Having trained with acclaimed vinyl mastering engineer Richard Simpson (RCA), our engineers have the experience necessary to deliver an exceptional record combined with the fresh perspective of a fellow musician (when they're not working, you can find most of our engineers on tour or in the studio with their own bands).

Mastered for iTunes: Infrasonic's engineers are "Mastered for iTunes certified" and work within the best practices of Apple's encoding and file delivery requirements.
