“Despite only having a relatively short relationship with Louis from Sine Sound Mastering, it has been an exceptionally fruitful one so far. My whole team and I have been universally impressed with not only the excellent results delivered by Sine Sound, but also by their fantastic service. Always on hand to answer queries and with an impressive turnaround time, Sine Sound set a benchmark other mastering services would do well to emulate. As to their results, I have found Sine Sound to be peerless at this level. Their masters are always a perfect blend of warmth, body and clarity and indeed stand up to comparison with anything else on the market. 10/10 would master again.”
