Get a free test master or mix evaluation

Use the form to choose a free test master or free mix evaluation, then tell us a little about your track and what you’re looking for.

Choose a free test master and we’ll master a section of your track so you can hear how your music could sound after mastering before placing an order.

Alternatively, choose a free mix evaluation and we’ll check your track for anything that may benefit from attention before mastering. If we hear a problem, we’ll let you know what we’d recommend changing.

Every mix is checked before we begin mastering, whether or not you’ve requested an evaluation.

IMPORTANT

On the next page, upload your audio files (WAV or AIFF only; please do not send compressed files such as MP3) and enter your own email address.

Smash will email you a verification code.
Enter this code in Smash to complete your upload.


Your files will then be sent directly to Orange Polygon.

Working with reference tracks

If you have reference tracks that represent the sound you’re aiming for, you’re welcome to send them with your project. They can help us understand your preferences for things such as tonal balance, dynamics, overall level and character.

A reference isn’t essential, and we won’t simply try to make your music sound like another release. We’ll use it as a guide while making mastering decisions that are appropriate for your own mix.

Why choose Orange Polygon for Music Mastering?

Online Mastering Worldwide

We work with established and emerging artists, producers and labels worldwide. Our online mastering service makes it easy to send us your music wherever you're based, whether you've recorded in a professional studio or your home setup. Masters can be prepared for streaming, vinyl and CD production.

Revisions Included in Your Mastering Price

We provide honest, transparent communication throughout the mastering process. Up to two revisions per track are included in our pricing, so if you feel your master needs an adjustment, you can request changes at no additional cost.

Mastering Tailored to Your Music

Every project is approached individually. You can discuss your music directly with a professional mastering engineer and tell us what you're looking for, whether that's a particular tonal balance, overall character or a reference track you'd like us to work towards.

Competitive, Release-Ready Sound

We master your music to translate reliably across different playback systems and sit confidently alongside commercial releases. Loudness, clarity, dynamics and overall tonal balance are carefully judged for the music, rather than treated as one-size-fits-all targets.

Experience & Mastering Equipment

More than 25 years of music industry experience informs every mastering decision. We work in an acoustically treated studio using carefully selected analogue and digital processing, choosing the tools that best serve the music rather than following a fixed processing chain.

Our Studio

Our purpose-built mastering studio provides an accurate, controlled listening environment where we can make confident decisions about your music.

Careful acoustic treatment, detailed monitoring and a combination of high-quality analogue and digital equipment allow us to hear what a mix really needs — and just as importantly, what it doesn’t.

Every mastering chain is built around the music. We choose the processing and signal path to suit each project rather than applying the same approach to every master.

Frequently Asked Questions

Everything You Need to Know About Online Mastering

Mastering is the final stage of audio production, where a finished mix is carefully prepared for release. We assess areas such as tonal balance, dynamics, stereo image and overall level, making adjustments where needed so your music translates reliably across different playback systems.

Every track is treated individually, with the aim of enhancing the mix while preserving its character and the decisions you made during mixing.

Most masters are completed within a few days to a week of ordering. We’ll keep you informed throughout the process and let you know when your masters are ready to download.

Your mastered tracks will be supplied as high-quality 24-bit WAV files, ready for digital distribution and streaming. If you’re releasing on vinyl or need files in a different format, let us know and we can provide masters prepared for your specific requirements.

AI mastering can be a useful automated option, but it can’t make the same considered decisions as an experienced mastering engineer. We listen to your music, assess what it actually needs and tailor the mastering accordingly, using analogue and digital processing where appropriate. You can also discuss your music directly with us and request revisions if needed.
