Stuart Firm - UK

Thanks to SDR Audio and Mr Shaun Rayment I’ve managed to record and absolutely fall in love with my debut EP “Dill With it”…I can’t thank Shaun enough for his faith and support in my endeavors as an artist!….much love

Paul Dillon - UK

My band, Before I Go, just got the finished masters back from SDR and we are very happy with the results. Shaun gave guidance, help and overall 1st Class service and really made the EP what it is. Highly recommend his services and we will definitely call to him again!.

Connor Sasse (Before I Go) - UK

Shaun listened to everything that was required and executed it superbly. A brief extra recording session to finish one track was superbly professional and consultative. All told our experience was a fantastic one, and we will be resuming our partnership with SDR in the autumn.

Phil Stoker (ZenthetiX) - UK

World class mastering. Cheap and fast. I’ve used Sterling Sound before and SDR’s results were better. Easy to work with.

Prahlad Little (Prahlad) - AUSTRALIA

Shaun mastered our EP and it sounds great. I’ve had tracks mastered at London studios for 3x the price and half the quality. Communication is so important in the mastering process and Shaun was in constant contact making sure everything was exactly as we wanted it. Can’t recommend enough.

Minque - UK

Absolute legend of a guy. Definitely record here if you want a top professional job.

Alexander Cooper (Eyes To The Skies) - UK

Professional, quick and patient. Love the sound of the SSL compressor on the mix bus.

Samhain Carter-Brazier - UK

Couldn’t have wished for a better experience than this one. A very pleasant guy to work with, wonderful communication, and he lifts your music to heights you wouldn’t dare to hope for! Be it mixing or mastering your record, Shaun is the guy you want doing it!
Thank you for a marvelous experience and a fantastic result.

Håvard Lunde (Moonscape) - NORWAY

Shaun is an excellent dude to work with, and he’s highly dedicated to deliver you the highest quality mix and master for your project for a decent price. I highly recommend that you take your album-project to Shaun and put it in his highly capable hands.

Lars O. Antonsen - NORWAY

Very pleased with how our single turned out from Mastering. Great suggestions on the mix, communication, and catering to the needs of the genre and customer. Highly recommended!

Kyle Rice (Apheresis) - USA

Worked with Shaun on our latest “Don’t Come Crying To Me” E.P. by Desperate Eyecon.
Shaun was fantastic right from the off, letting me know when our mixes weren’t quite doing us justice and how to sort it. Shaun then Stem Mastered all 5 tracks and the results were fantastic! All the time there was a constant dialogue between us, really taking the time to know what we wanted. We’re thrilled with the results and will be using SDR Audio Production on our next project. Highly recommended!!!!! Thanks Shaun!!!

Desperate Eyecon - UK

Love working with Shaun, he has taught me so much about pre mixing and giving me some great learning tips. He is very easy to work with and he will make sure you do the best you can, so you can get the best out of the product. Shaun has worked with me for the last couple years and we will be working together for many more.

Ian Mortimer (Drop Oblivion & Skin For A Canvas) - UK

Shaun recently mastered 3 tracks for our debut release and we were all extremely pleased with the results. Not only did he fully understand our requirements he did a great job with stem mastering the vocals with the instrumental tracks and, as a result, gave us a good set of masters which we can use for promotion.

Will Kelly (CFO Productions) - UK

Brought really nice space, depth and thickness to my mix, would highly recommend.

Ollie Robinson - UK

Shaun gave me very precious advice on a mix that I was working on; and helped make my mix come out even better with the Mastering that he did. I’d definitely recommend working with him!

Melik (Bitter Heart) - TUNISIA

No word in this page description is exaggerated. Shaun is a great guy who knows his job and really cares about client’s music. I sent a track for mastering and after like couple of hours I had a top quality result on multiple formats for distribution via different medias. Shaun explained what my mix lacked and how he fixed it in mastering, resulting with dynamic, full and lively sound. Definitely worth recommendation I think it’s not the last time we cooperated.

Grzegorz Tusznio - POLAND

If you need a professional mastering service, then all I can say is your at the right place!!
After working with Shaun on our album, the end results are amazing
very well priced very fast turnaround and very professional service indeed
Shaun is a great guy to work with.

Undurskin - UK

Best studio engineer I’ve worked with. Mixed and mastered my projects perfect and added his own ideas on things using his experience. All round solid guy, look forward to working with you again.

Daniel Ebrey - UK

Shaun is the man! Easy to work with, great ear for bringing out the best in your tracks, super organized and professional and just a good dude. Highly recommend.

Tim Herscovitch - USA

If you’re looking for a professional mastering engineer I would highly recommend Shaun Rayment from SDR Audio Production. He did a brilliant job for our audio track which was recorded as a Prophet XL promo (available on Youtube). The bass frequencies sounds very warm and natural , the drum got very organic sound and guitars and synths are just huge. Thanks for making the tune so real.

Andrzej Czaplewski - UK

Highly recommended. I threw a vaguely jazz piece at Shaun, and of course he aced it. I haven’t used an outsider for mastering before (and listening to my stuff again now, it shows). What was great with Shaun was the feedback. I was able to tweak my mix a couple of times so he could bring the best out with his skills. I learned a hell of a lot in those couple of tweaks.

Ivor Randle - UK

What a great guy Shaun is! This is my first release and I needed a bit of hand-holding through the process. Shaun is so patient and also was determined to get the right results for my song, thanks again, Shaun. Speak soon for my next release!

Samantha Scott - UK

Great service and very helpful. Make your track sparkle!

Chris Mather - UK

Excellent work. And professional service. Will defiantly be using again. Highly rated. (Mastering)

Adam Hart - UK

We had our first project with Shaun and it was an absolute pleasure working with this professional. The Quality of the Mix & Mastered sound track was above our expectations. Reliability, communication and professionalism at it’s best. Thanks Shaun for your service and will be in touch very soon with more projects.

Shahid Munir - UK

Very professional and helpful, have learned a few things about premasters, a nice guy too and the results were outstanding. Will definitely use SDR on future projects! (Mastering)

What is Mastering?

Mastering is the final stage of a professional audio recording once the mix is completed. The main purpose is to get the audio to translate the same way as it did in the studio environment in the “real world”, when played back on the vast number of different audio systems, broadcasting and digital streaming providers out there. It turns the final mix of a track into something that is ready for consumption at the standard needed and compared to in today’s music industry. Ensuring things are balanced tonally and hitting the correct target loudness levels required. 

When working with a collection of audio recorded at different recording studios, with different mix engineers and at different times, Mastering can be used to bring the collection of tracks together to sound more like they are from the same recording sessions as each other. Helping them all fit together more convincingly to the ears of the end listener.

When working with problem mixes, some things can be fixed at the Mastering stage. However some things can just never be fixed regardless of how much treatment is applied. For this reason it is always best to be in a position to be able to go back to the original mix sessions to make any adjustments that could be highlighted in the Mastering stage.

Mastering can involve different types of EQ treatment, multiband and stereo compression / limiting, mono and stereo balancing, stereo width enhancement, de-essing, harmonic saturation, noise reduction and much more. It is also at this stage where the final track order is constructed, ISRC codes and track text information is added, and produced onto the formats needed for duplication and distribution of the final product.

When working together you receive a truly personal service, starting with me listening to your material and providing mix feedback that can be invaluable for improving the final product, allowing me to focus on using the Mastering process to fully push for the limits of sonic enhancement, rather than fixing things with more invasive processing.

What type of final mix format is best for Mastering?

There are two ways for the final mix to be sent for mastering. The first is a Stereo WAV file of the final mix, which I always prefer to work with if the mix itself is of a professional standard.

However, for more control over the different aspects and instruments of a mix, the “Stem Mastering” process can be used. This is multiple Stereo WAV files that contain the mix broken down into individual instruments, which once put together recreate the final mix exactly how it was. Stem mastering is recommended for achieving better results with problematic mixes.

More information on Post Mixing & Stem Mastering services can be found HERE

I like to work with 48kHz/24bit WAV files, but 44.1kHz/16bit and 96kHz/32bit is also accepted if the project has been recorded/mixed in that sample rate. What is most important is I work with the same sample rate files as the project has been created with. Please inform me of these details when sending the files.

When rendering/exporting/printing final mixes and stem files for mastering, please keep peaks on the main mix/tracks between -10 dB to -4 dB, but no higher than -3 dB. If the meters are peaking over 0 dB, please lower the individual mix elements to remove the overload. By sticking to these guides, this will ensure I have the headroom needed for professional mastering. If any processing has been done on the overall mix (for example Compression and EQ), please inform me of what has been used. If a version of the final mixes can be rendered/printed without this processing, please include these as extra options for mastering.

Reference Tracks?

Please include any reference tracks you may have of other artist’s material to demonstrate what kind of sound you are aiming for in regards to the final production.

Mastering can be done for CD, Vinyl, Digital formats, and can be completed to “Red Book” standards.

No Revision Limits (within reason).

Final Delivered Mastered Files Include – 24bit Digital WAV, 16bit CD WAV & Highest Quality MP3 formats as standard.

Stem Mastering and other formats (including DDP) are available at additional costs.
