Having started AIR Mastering in 2006 with the legendary engineer Ray Staff, AIR completed the acquisition of Alchemy Mastering in August 2020. The new mastering operation is now branded as Alchemy Mastering at AIR.

Co-founded by Barry Grint and Phil Kinrade, the high-end audio mastering outfit has gone from strength to strength throughout its 22-year history, establishing a distinct reputation as one of the most forward-thinking studios in the industry.

Following the acquisition, AIR will continue its mastering operations while expanding their current facilities at the iconic Lyndhurst site. Meanwhile, a part of the team led by Alchemy’s founder Barry Grint will remain at their current Hammersmith location with a view to joining at the AIR headquarters in the near future.

The new Alchemy Mastering at AIR specialises in all formats of analogue and digital mastering, providing high-end audio services to the global music industry. From independent artists to major labels and cult TV soundtracks to Hollywood blockbusters, our team has the craft and vision to enhance your release.

Your tape or digital audio is fed through our range of top-end analogue/digital processors. We produce a digital WAV file for use on all music streaming services.
We cut your audio onto a 14" lacquer (a pre-master) ready for the pressing plant to create your vinyl records. Our experienced engineers perform the transfer on our VMS80 cutting lathe and ensure your music is optimised for the format.
Previously known as ‘Mastered for iTunes’ Apple Digital Mastering is a specialist workflow that ensures the stamp of approval from Apple when buying or streaming music via their services. Each of our engineers are certified with Apple to carry out this process.
Recording, mixing and vinyl come together as we record live performances from Lyndhurst Hall or Studio 1 directly onto a vinyl pre-master in our mastering room. This is the ultimate pure analogue recording.
Vinyl mastering but with the turntable, electronics and audio set to half its original speed. Your tracks will benefit from improved groove ‘accuracy’ as the cutting takes twice as long to transcribe the audio. This reduces mechanical stress and results in a smoother, more natural top end.
CDs are still commonly used for physical music sales. AIR will master, sequence and create DDP pre-masters for your CD replication.
