The Only Service That Does & That's Why We Get The Best Results

Mixing - Isaac Grinsdale

My Name Is Isaac. When you work with me, I promise you a world-class final mix.  This is made possible by the top quality analog and digital equipment as well as the monitoring and room acoustics to create the most accurate listing environment possible.  

I also work closely with a dedicated mastering engineer Filip Pietrzykowski to make sure the final result is the best it can be.

After you are happy with the final Mix it is then sent to Filip Pietrzykowski: A dedicated Mastering Engineer.

Mixing Studio

The Mixing Studio

When you work with me, I promise you a world-class final mix.  This is made possible by the top quality analog and digital equipment as well as the monitoring and room acoustics, all of which have been installed to create the most accurate listing environment possible.  

This all means I can make informed decisions about how to mix and master the project at hand, ensuring it translates well to other systems such as the car stereo, headphones, and hi-fi systems.

In short, once it’s mixed here with me, it will sound great everywhere.


The studio has been designed to give me a flat frequency response. This provides me with the optimal environment in which to mix your music. Acoustic treatment includes bass traps in each corner of the room and a series of Vicoustic Multifusers to ensure I can hear excatly what's going on within your music.


My monitoring systems (the speakers that I use to listen with) are a world-class selection of monitors, including a pair of Adam P11 speakers and matching subwoofers, single diver Avantone Mixcubes and Beyerdynamic DT 990 Pro headphones. This collection of various monitoring systems allow me to make accurate mixing decisions with ease.


With my online music mixing and mastering service I have chosen my mixing equipment with meticulous attention to detail, with both quality and versatility in mind.  As an engineer it’s important to have this variety of tools, ensuring I have the gear needed to achieve the vision you have for your songs.

Having another set of ears to make the final changes, with dedicated expertise, world-class mastering equipment and room acoustics always gets the best final results.  
I send my mixes to studio for the final touchs to be made, rather than mastering myself. This is included in the price.

After the final mix is complete your music will be sent to a dedicated mastering facility at Red Mastering Studios. 

They have a larger, even better sounding room, which has the acoustic treatment that is very similar to that of the extremely successful George Messenburg studio.
