Online mixing & mastering services

Welcome to your one-stop source for bold & striking audio

Why GreenRoom Sound?

World-class mixes & masters. Modern approach. Artist-friendly rates. 

Our goal is to provide each client with an experience that rivals much bigger and more established studios. We strive where most big and often outdated studios fail – offering world-class, flexible mixing & mastering services tailored to the present-day band, artist, or brand. We simply aim at producing the best recordings possible, in the smoothest way possible.

The studio is operated by multi-awarded musicians and audio professionals active on the music scene, being aware of and actively participating in the modern music trends and the world of audio production. With the ever-growing, high-quality gear list, our attention to detail, and the ability to build, shape and transform a rough idea or mix into a radio-ready song, we’re certain that we can meet and exceed our client’s expectations.

Up-and-coming artist in need of creative input and technical solutions to your audio “problems”? Ambitious band looking to level up and create your own sound and define your style? Seasoned professional looking for a “second set of ears” and sonic polish? We’d like to hear from you!



A mix can really make or break the sound of a song or album. We strive for punchy & bold  mixes carved meticulously using a variety of analog and digital gear.

We specialize in rock, metal, alternative pop, and modern progressive genres, although all genres are accepted – sonically enhancing the message and the emotion of a song is always a priority, regardless of the genre!

We’re strongly against the templated, cookie-cutter, one-size-fits-all approach, and we like to treat every project differently. Rates vary depending on the project, so please get in touch for a quote.  No project is too big or too small for us.

No matter where you are in the world, we’d love to help you get the best results with your music!


Mastering is the last step before your music is released to the public. It’s not only quality control – making everything technically correct is only a part of the process. A good master translates the power and emotion of the song to a wide range of playback systems, expanding its appeal to the widest possible audience. 

During mastering, we enhance and sometimes fix your mixes, ensuring that the final result is a pristine master, optimized for any streaming platform or physical medium.

Stem mastering is also available, and it’s our preferred method for self-produced, home studio projects as it gives us more control over the important elements and the balance of your material.

Please contact us for a quote. We’d be happy to supply a free mastering sample if required!

All-round song enhancement

Here at GreenRoom Sound, we take pride in our relationships with past and current clients. We strongly believe that providing knowledge and supporting up-and-coming artists is the most effective way to keep the music going forward.

Along with the mixing & mastering services, we offer a FREE review of your mixes or songs in general and FREE mastering sample to all new clients.

Editing, tuning vocals, MIDI programming, and audio restoration services are available at artist-friendly rates.

Need something extra for your song? An epic guitar solo, background vocals, or full arrangement makeover? You’re in the right place!

In short, feel free to get in touch for ANY question or requirement you may have!

Free mastering sample or mix consultation, if requested, will be provided at this stage as well. 

Once the project is defined we’ll start working on your music. A link to the first completed mix/master will be sent for you to review. At this stage, you can approve it as a final version, or request a revision. Once you’re 100% happy with the result, we’ll send you the final mixes/masters.
