About AGU

Hi, my name is Iwan

And I am a professional mixing and mastering engineer from the Netherlands, as well as an independent artist.

I’ve been involved in music for the past 15 years and it’s been the love of my life.

Since 2023 I’ve gone full time as an Engineer and haven’t looked back since!

I also produce music as an Artist under the moniker of AGU.
This project has also really taken off these last years and I’m proud of my work.

Nice to meet you 🙂

Mixing & Mastering

Mixing is the process that comes after the production of a song.

It’s main goal is to get a good ‘mix’ by making sure all volume levels are balanced and bringing the right elements to the center of attention.

By making good use of EQ’s, Compression, FX’s (like Chorus or distortion) amongst others a mixing engineer molds the track into a finished stereo mix.

It is a creative process that can add a lot of flavor, depending on the wants and needs of the client.

Mastering is the process that comes after mixing.

It is the final step before your music is ready to be distributed. A fresh set of ears, superb monitoring and years of knowledge make for the perfect final ‘bastion’ of the production cycle of a song.

A (small) part of the mastering process is also to make sure a song is loud enough to be commercially viable!

In mastering, it comes down to those final 10-15% to bring a song to life and help it translate on all sorts of playback systems.

The most important thing for me is to understand you and your vision for your precious music. I’m here to help you and your music come to life and communication is key!

Some kind words of those who came before you!

This is what they had to say:

François Tétu

“Truly went above and beyond to help me craft a mix that conveyed the emotion of the track properly, giving me feedback AND technical guidance, before he even started to master the track. That’s how much he cares about his customer’s art. Of course the master was also great.”

“AGU / Iwan is truly a wizard of audio engineering. He worked with me so closely through every step of the process and even gave me advice on how to improve my mix. You can tell he not only truly cares about music, but he truly cares about YOUR music. He is the only person I would trust to touch my music and he took my own favourite song of mine and brought it to a whole new level. I will now feel confident putting this song out on all platforms and playing it live too. Thank you so much for being such a wonderful engineer and collaborator AGU. Getting to work with this incredible musician and engineer is truly a privilege!! <3”

“Working with AGU has been an absolute game-changer for my music. The professionalism, attention to detail, and incredible sound expertise he brought to mastering my tracks was beyond impressive. Every track came back sounding polished, dynamic, and club-ready, with perfect clarity across all frequencies. I’m especially impressed by how well the tracks translate across all playback systems, from high-end club speakers to headphones and even car stereos. The turnaround time was fast, and the communication throughout the process was smooth and professional. I’m thrilled with the results and can’t wait to collaborate again on future projects. Highly recommend to anyone looking to take their music to the next level!”

“I honestly love working with Iwan so much. The level of professionalism and knowledge he has to offer is just off the charts! It’s so valuable for a small independent artist like me to have so many tips and information to actually improve my work and get such amazing results. I’m so proud of my music now thanks to Iwan! He knows so much about everything audio it is truly so so valuable. Thanks again for your amazing work and I’ll be back for more!!! (: Cheers!”
