Mixing & Mastering

Karri Kallio on SoundBetter

Hello! I´m a freelance recording/mixing engineer, composer and producer from Seinäjoki, Finland. I´m a part of a music production team called HallaFreakquency. I love to mix and master all kinds of music but I´m most experienced in metal, rock, pop & pop-rock.

I work out of our own in-the-box based mixing studio in Seinäjoki. We have a huge collection of audio software and plugins from the best manufacturers like Slate Digital, Waves, Steinberg, DMG Audio, Cytomic, Native Instruments, Toontrack, UVI, Nomad Factory etc.

I rely on Adam A7X speakers as my main nearfield monitors and also use Sennheiser HD600 headphones to gain another perspective.

I work mostly remotely but if you are located in Finland, you are of course welcome to join me to put in the finishing touches into the mixes.

Interview with Karri Kallio

  1. Q: Tell us about a project you worked on you are especially proud of and why. What was your role?

  2. A: Zerafia´s debut album. I produced, recorded and mixed it together with my colleague. We also played a major part in arranging the songs. It´s the most comprehensive project I´ve been involved in (excluding my own bands).

  3. Q: Analog or digital and why?

  4. A: Digital and in-the-box. Because it is much more convenient (recalling, revisions etc.) and nowadays there are lots of fantastic plugins. I´m also quite good at creating "analog vibes" in the digital domain if that´s what the client wants.

  5. Q: What do you like most about your job?

  6. A: The music. Especially making the music "tick".

  7. Q: What's the biggest misconception about what you do?

  8. A: A lot of people tend to think that editing, quantizing and tuning tracks are a part of mixing. They really aren´t. I do some editing work within my mixing jobs but one shouldn´t assume extensive editing is included in the mixing fee.

  9. Q: If you were on a desert island and could take just 5 pieces of gear, what would they be?

  10. A: My headphones, a laptop, an interface/preamp, an electric guitar and an instrument cable.

  11. Q: What was your career path? How long have you been doing this?

  12. A: I started recording and mixing as a hobby about 10 years ago, doing mostly demos for my own bands. The last couple of years I´ve been working as a freelance audio engineer, composer and producer. In addition to recording, mixing and mastering I write and produce production music and stock music.

  13. Q: Can you share one music production tip?

  14. A: The sound is about the big picture ;)

  15. Q: What type of music do you usually work on?

  16. A: Rock, metal, pop & pop-rock.

  17. Q: What's your strongest skill?

  18. A: Definitely mixing

  19. Q: What do you bring to a song?

  20. A: I take my mixes well beyond getting a nice static balance. I like to use quite a lot of volume automation but I also tend to automate effect sends and EQ´s when I feel the need. I usually like to get the song represent its dynamic and/or dramatic arc as well as possible. My mixes keep the listener glued to the song by bringing up front the song´s focal point in each song section. I also concentrate quite a lot on the long-term dynamics of the song to make it stick.

  21. Q: Tell us about your studio setup.

  22. A: I own a mixing studio with my colleagues. The studio is based around an extremely powerful PC and a huge collection of audio software and plugins. We have Adam A7X as our main nearfield speakers and Sennheiser HD600 as headphones.

  23. Q: What other musicians or music production professionals inspire you?

  24. A: e.g. Adam "Nolly" Getgood, Nino Laurenne, Mikko Herranen, Chris Lord-Alge, Kurt Ballou

  25. Q: Describe the most common type of work you do for your clients.

  26. A: Remote mixing and mastering
