Our London Studio

Our acoustically treated mixing and mastering room has been specifically designed to create the perfect listening environment for professional mastering music. We spent years on improving quality of room so that it can provide optimal mastering and mixing services. It has made-to-measure the auditory treatment resulting in a clear and precise sound every time, allowing us to really hear the song that we are working on. This means that not only are we able to pick out even the tiniest of details, but coupled with our state of the art equipment we are able to produce masters that will sound great on any system time after time.

Mastering Equipment

Our mastering and mixing services have managed to acquire such impeccable popularity because we use some of the best digital and analogue mastering equipment.These have been specifically chosen over the years to function well with the studio and for generating the best possible results.

Audio Mixing and Mastering Engineer: Filip Pietrzykowski


Mastering Audio

Pre-Mastering Audio is the final and last stage of mastering music online. The engineer appraises the material from a technical point of view to give it a final polish before duplication. In case of an album, all its elements are being brought together to make them sound as a united whole.

The most important part of professional audio mastering is critical listening the audio material in a room with good acoustics and a very accurate monitoring system. In these conditions, a mastering engineer is able to pick up even minor flaws in the mix which can then be rectified before the material gets released.

Audio Mastering entails a degree of audio processing like equalisation, level adjustment, compression, limiting etc. in order to enhance the sound of the material and optimise its translation on various playback systems. Please read more here.

CD Mastering vs Mastering for Vinyl

CD Mastering services must not to be confused with digital mastering. The latter is a process of working 'in the box' and using plugins only. It is the most popular form of delivery of audio masters and one that our clients usually opt for. But Red Mastering also focuses on Mastering for Vinyl, which is becoming increasingly popular due to the renaissance of that medium.

Owing to the years of experience, our engineer understands what the audio must sound like before being sent for cutting and for the vinyl to sound perfect. Vinyl has its physical limitations and an engineer needs to know how to use the EQ to reduce overly wide stereo low frequencies and check for excessive high frequencies, making sure they are not too fast or abrasive. If such issues are not fixed and looked at, the vinyl will not play properly once it is cut, causing the needle to jump about at the sound of every high or low frequency. 

While handling CD mastering services or mastering audio online for vinyl, our engineer uses very little compression, no limiting and never clipping a/d - which is very common when mastering for digital distribution.

It also helps to have a good relationship with the cutting studio, know what equipment they use and understand its capabilities. A mastering engineer can then be confident that the audio file they send out for cutting will sound exactly as they intended once pressed on vinyl.

Mastering Vinyl technically also involves the process of cutting the vinyl. Before the era of digital mastering, a mastering engineer would not only prepare the sound for the vinyl but also cut it. Nowadays, the cutting studio receives a digital file and then the vinyl is cut.



Stem Mastering


With respect to professional mixing and mastering services, stem represents an instrument or a group of instruments so that you can control the changes you make to each sound individually. A mastering engineer will usually work with a few stems which, when added all together at equal volume, will create a whole sound as though it was simply a single stereo file.

How many stems the mix is broken down into depends entirely on the clients’ and producers’ needs and can range from two stem mastering, where it will usually be the vocals and the backing track, or it can even include a stem for each individual instrument.

As each stem can be manipulated and adjusted individually without compromising any of the other sounds/stems, this gives the engineer more control and makes it far easier to fix any faults in the mix, as well as apply any artistic influence that may be wanted by the client.  

Stem mastering is almost an in-between mixing and mastering services and is not chosen as a standard service, as it is more costly and involves more work. Stem mastering is usually not needed and may be required in the case where, for example, only one track has issues that need fixing. It is also a useful service if a client cannot afford a mixer as well as a mastering engineer - in that case, they can use stem mastering, which will cover some basic aspects of mixing and provide a clean final master.

While stem master has many benefits, having access to stems can also result in changes that the client may not like. Receiving one stereo file usually stops this happening as the engineer cannot make changes to the individual stems. But if the client wants changes or some form of artistic input, then stem mastering can be the answer. If you have any queries or questions regarding stem mastering, please get in touch with us and we will be more than happy to help.
