Welcome to Tonalex

Affordable online mastering for the unsigned and independent music sector.

Hello There

We are Tonalex.

Terry Waker Bex Waker
Tonalex was established in 2012 by mastering engineer, Terry Waker, to provide affordable online mastering for the unsigned and independent music sector.

With an exponential rise of impersonal and sub-standard algorithm-based online mastering and the unaffordable reality of attended mastering sessions, Tonalex was created to provide reasonably-priced mastering, but without compromising on quality.

Growing up as a keen bass player and drummer, Terry studied at the Liverpool Institute for Performing Arts (LIPA) graduating with a degree in Sound Technology. He has worked in various roles in the music industry since 2006 and in his early career Terry worked in live sound at venues such as The Royal Albert Hall and Wembley Arena.

Bex joined Tonalex in 2022 to support with marketing and social media. A saxophone player herself, she has a passion for music, photography and more recently multimedia design.

What is Mastering?

Demystifying the elements of mastering.


Having a tonally balanced record helps to ensure that it sounds great across lots of different playback systems. Whether you listen on a phone, car radio or headphones, your track will sound great.


Great dynamics are essential to bringing your track to life! It's what gels your mix together, gives it energy and governs perception of volume.

Noise Reduction

This can be a hiss or hum in the background, ambience at the start/end of a track or noises that occur during; if they're not supposed to be there then we can attenuate them.

Stereo Width

Just like a landscape, everything has its place. If a track is too narrow then we can expand the stereo width to give it more depth and scope (and vice versa).

Album Sequencing

Track order, fades and spacing can have a huge impact on the final impression of your record. A dynamic album sequence can ensure that your record plays smoothly and keeps listeners engaged.

A Critical Ear

Often it's just a good idea to get another pair of experienced ears on your mix. Not only do we offer our ears but we can also advise you on CD replication, vinyl cutting and digital release.


We love what we do, check out some of our work.

Our Service

Affordable yet uncompromised.

We take great pride in giving unsigned artists and the independent music sector access to affordable online mastering, but without compromising on quality.

Here at Tonalex your track is not just another piece of data processed by an algorithm. Every master is uniquely crafted by the human ear.

Our rates begin at £30 per track. We're also able to offer alternate masters (vinyl, high resolution, etc) and DDP files (for CD replication).


Don't just take our word for it.

"Terry first did some mastering for my group Sandtimer in 2015 and we loved the results.

Our music is mostly acoustic-based so we needed someone who could apply a light touch while also delivering energy and warmth.

Everything he has done for us has been fantastic and we have never looked back!"

"I have worked with Terry from Tonalex since 2016, his support through my early days of music production has proved invaluable.

Terry has taken the time to understand my sound bringing out the very best in my vocal performance.

Tonalex gets the very best from my recording and mixing with their ability to explain in layman's terms when/where I may need to make amendments in the mix.

I would highly recommend Tonalex for their attention to detail and value for money."

"I’ve worked with Terry for many years and wouldn’t hesitate to recommend him to any other producers needing their work mastered.

He is very professional in what he does. Very prompt in replying and getting the job done.

Terry takes the time to understand your needs, is very accurate in his work and is a pleasure to deal with.

A top mastering engineer!"
