In order to achieve a truly realistic rendition of the musician’s performance, we use state-of-the art miking placement and techniques. Our studio is fitted with a wide range of assorted microphones and preamps (tube, condenser, dynamic, ribbon) in order to meet each artistic requirement on every song that we record. Most of the time, the recording engineer’s decisions and know-how allows the artist to completely forget about the technical aspects. This is critical because only a faithful rendering will contribute to the band’s unique character.

Mixing is the art of combining all the previously recorded audio tracks in a stereo space. For a perfect blend of all audio elements, we use filters (parametric equalizer, compressor etc) and effects (reverb, delay etc). To achieve the highly sought-after “warm” sound and to guarantee compliance with the song and artist’s interpretation, the Studio Sanatorium is fitted with a Digital Audio Workstation (ProTools HD), routed for frequency processing and summing to an analogue TAC Amek console of the Matchless series, having proven its value over many years. Various dynamics and effects processing are carried out by hardware devices selected among the wide available studio range of rackable units.

Mastering is the final step on stems or mix. Whether you need to balance the many tracks of an album or calibrate the output level in compliance with a broadcasting standard (Red Book, Spotify, Youtube etc) Studio Sanatorium offers various solutions. On a stereo mix output, all processing will be carried out in the digital domain with powerful tools. When mastering stems, an analogue summing of audio buses will be carried out upstream through the console, including some frequency adjustments if required. Once printed, the summing result will be ultimately processed through digital tools.
