Wrapping Up 2025

Hello,
I’m Jooyoung Kim, a mixing engineer and music producer.

Another year has already come to an end.

As the year draws to a close, I always find myself looking back—wondering how I’ve lived up to this point, and whether I’ve really been living well.
These days, I’ve been stuck in an endless cycle of thinking, and daily migraines have become a familiar companion… 🙂

Still, I thought it would be good to sit down and organize what I actually did this year.

1) Finishing my “Basics of Mixing” blog series

The book itself was published last September, but I continued writing blog posts on the same topic, just like before. I finally wrapped that series up this March.

2) Focusing more on papers and research this year

One year ago, a KCI (Korea Citation Index) paper of mine was published, and this August I published an SCIE-indexed paper with a journal affiliated with the European Acoustics Association.

Thanks to those two papers, I was able to reduce my tuition a bit, and perhaps because my advisor viewed my work positively, I was appointed as a graduate-level lecturer in the second half of the year.

I also developed a Python-based audio measurement tool for my research, implementing THD+N and crosstalk measurements in accordance with the AES17-2020 standard. A paper related to this tool is currently under review, following IRB approval from my university.

As for my deep-learning research, about half of the data was lost, so I’m retraining everything—but surprisingly, the results are turning out quite well. I think I’ll be able to carry out the experiments properly. I’d like to wrap it up by February, though that might be a bit ambitious… haha.

If I had one small wish… it would be nice if lecturers were also eligible for research funding. 🙂

3) Graduating from graduate school

I don’t remember why I ended up sitting in the center, but my graduate school at Sangmyung University held thesis defenses at a retreat facility. It feels like a long time ago, but that photo was taken in May—so only about seven or eight months have passed.

4) Teaching, both regularly and irregularly

In addition to the practical courses I’m responsible for, I also gave thesis-related lectures at graduate school and a few external lectures. It definitely felt very different from the private lessons I used to give upon request to people I knew personally.

5) Starting a sole proprietorship and doing live sound work

Registering the business itself wasn’t anything grand or impressive, so I deliberately didn’t talk about it much on the blog until now. I simply rented a virtual office and registered the business… haha.

I wanted to wait until I had a proper studio before mentioning it, but since I did register it this year, it felt worth noting. At the moment, I’m looking for a small place to set up shop—but finding a location that meets my expectations hasn’t been easy.

As for live sound, there isn’t much that’s been officially released as videos or albums yet, but a performance I supervised as sound director this past summer was recently uploaded to YouTube.

I’ve been doing things like this.

6) Obtaining a stage sound certification (in Korea)

At first, when I learned about this certification, I wondered if it was really necessary. But it turns out it actually helps in real life—so I crammed and got it done this year. Haha.

The audio-related knowledge wasn’t too difficult, but the legal terminology and stage equipment terms were tough to deal with.

7) Attending conferences from time to time

At the moment, I conduct all my research alone, and I do trust my own judgment—but I genuinely want to collaborate and work in teams as well.
Especially when I think about how much faster my current training runs would be with an expensive GPU—what takes weeks now could be done in days.

Beyond that, I really want to explore more interdisciplinary research.

8) Winning an award at a Japanese composition contest

It wasn’t anything huge—just an encouragement-level award—but it still gave me a meaningful boost.

After the contest, three Japanese composer agencies invited me to submit another piece for internal review and potential artist selection. Unfortunately, that didn’t work out in the end.

That meeting was later turned into YouTube content. The submitted tracks themselves weren’t publicly released, but there were critiques for each piece.

If you watch the video, it starts from the part discussing my song.
There was advice that touched exactly on the things I had vaguely sensed myself—especially regarding drums, percussion, and compositional detail. It felt like it was time to think more deeply about those again.

Akira Sunset mentioned that he liked my voice and singing, which was a small comfort. Another reassuring thing was hearing that my pronunciation didn’t sound awkward for a Korean—it felt like the effort had paid off.

9) Studying English seriously

I still feel that my English is far from good enough, but this is probably the hardest I’ve ever studied English in my life.

Back when I took the Korean CSAT, English was my weakest subject, so my strategy was basically “do well on everything except English.” If I remember correctly, I got eight questions wrong—five of them in English. Everything else was a top grade, but English alone landed me in the third tier… haha.

That said, I’m still far from my target TOEFL score. The program I want requires an 86 overall, but with minimum scores for each section, and if I want to apply elsewhere, I really need to break 100.

My best score so far is 85, so there’s still a long way to go. I suspect English will continue to torment me next year too—but there’s no choice but to keep going. Hahaha.

10) Designing my own hardware (still in progress)

It’s not finished yet, but I’ve been designing my own hardware.

If I call myself an audio engineer at all, shouldn’t I design and build at least one piece of hardware before I die?

Back in the day, EMI (now Abbey Road Studios) had a dedicated hardware department called REDD. As a one-person engineer, I figured I shouldn’t fall behind… haha. (Though honestly, the insane price of hardware is a big motivation too.)

Of course, not everything comes purely from my own head. Thanks to AI, I’ve been able to quickly simulate ideas I used to only imagine and lay down the groundwork.

The image above is the schematic of the hardware I’m currently working on.
It’s a tube saturator combined with a Baxandall EQ.

If it sounds good, now that I have a business registered, I’ve even thought about selling it as a DIY kit.

A fully assembled product would obviously be more convenient for users, but in Korea, all assembled electronic devices must pass KC certification.
That process is expensive, and for small-batch production, the cost inevitably gets passed on to the consumer.
All solder would also need to be lead-free.

Well… just indulging in a bit of imagination.

The schematic is mostly done, but I still need to run simulations—so I’ll just have to try it. If it doesn’t sound good… endless revisions await..T.T

11) New gear purchases

  • 2 × RODE NT55
  • 1 × Peluso P87
  • 1 × HA73EQX2
  • 2 × mic stands
  • 1 × Korg MicroKorg XL

That’s about it.
I definitely spent less than last year.
Except for the MicroKorg, everything was bought out of necessity… haha.

Closing Thoughts

I kept saying I’d release music, but in the end, I didn’t release anything this year. I do have some material prepared, but maybe it’s just inertia—or maybe I’ve been too good at making excuses about being busy.

I think personal performance activities would help create some synergy too, but it’s been so long since I last performed or played live that I sometimes wonder if I’ve lost my drive. I think, “Maybe next year?”—but moving forward alone is always harder than it seems.

Still, I really do need to release some music.

I’m 30 now—not exactly young anymore.
That makes me think even more seriously about how I should live. Sometimes I wonder if these are the same kinds of worries Kwang-seok Kim (Korean folk musician) had around this age.

I hope that next year, I’ll be able to wrap things up with a brighter and more hopeful mindset.

Thank you, always, to everyone who visits and reads my blog. I hope the new year brings both you and me many moments where we can smile naturally, without having to force it.

That’s all for this year. I’ll see you again in the next post!

Life Update (Dec 23, 2025)

Hello!
I’m Jooyoung Kim, a mixing engineer and music producer.

The weather has suddenly gotten much colder these days—hope everyone is staying healthy.

As for me… I caught a pretty bad cold and honestly, it’s been rough.

It’s been a while since I last wrote a post, so normally I’d pick a proper topic and organize my thoughts.
But today I’m a bit worn out, so I’ll just keep this as a simple life update.

First, a paper I submitted on a relatively straightforward topic was rejected by JASA.

Rejection itself is nothing new, so that part didn’t bother me too much—but it was a desk rejection that took two months, which honestly stung a little.

As soon as I saw the decision, I resubmitted the work to JAES, since I had already prepared a version in that format. If it doesn’t work out there, well… there are other options. I’ll just have to wait and see.

Next, I sold my HA73EQ and picked up the HA73EQX2.

I’ve been consistently satisfied using it for recording, tracking, and EQ work,
and I’d been wanting to do more stereo tracking as well.

I did consider the Phoenix Audio Ascent, since the price was appealing,
but on the EQ-equipped model, the mic input and line input aren’t separated—which ultimately led me to choose this unit instead.

Of course, I could work around that with a patchbay,
but if phantom power is engaged and a patch cable gets bumped or shorted… well, that could be the end of a very precious microphone..^^;;

I’ve already finished all the measurements on this unit,
so I’ll write a proper review when I get the chance.

Also, the headband on my main headphones finally gave up.

I’ve been using the Ultrasone Pro 2900,
and while replacement earpads are easy to find, I couldn’t find anyone selling just the headband.

In the end, I ordered some Velcro and a headband cushion from AliExpress and fixed it up myself—simple and effective.

And after a very long time, I finally traveled to Japan again.

Actually, now that I think about it, this was my first real trip in ages.
The last time I traveled was around April 2019, to Sapporo—so that makes it about six years and eight months.

I visited Kyoto and Osaka. Kyoto, in particular, stood out for its clean air, mountains, and nature. The farther you go from the city center, the more rural it feels—it reminded me of visiting my grandmother’s house when I was younger.

On the way back after visiting a temple, I came across a small jazz band I’d never heard of before.

I found myself thinking, “Wow, that’s a really compact kick drum—interesting,” as I watched them play. The sound level was comfortable and easy to enjoy, which made the whole experience even nicer.

In Osaka, I visited the famous Osaka Castle.

To be honest, though, the inside felt like little more than a concrete museum, which was a bit disappointing.

I also stopped by Miki Gakki to check out and play some acoustic guitars.

Unfortunately, none of them really moved me.
I tried some fairly expensive models too—like the Collings D2H and the Martin D-42—but still didn’t feel that spark.

I suspect the space itself wasn’t ideal for evaluating guitars acoustically, which may have played a big role.

As for the cold—it probably came from walking long distances during the trip,
and then continuing to work on paperwork back at the hotel without much rest. The fatigue caught up with me.

Please take good care of your health,
and I hope everyone finishes the year safely and peacefully.

I’ll see you again in the next post. ^^

2024 Year in Review

Hello! I’m Jooyoung Kim, an engineer and music producer.

It’s already the last day of 2024…
It feels like I’ve barely done anything, yet the end of the year has come around again. 😊
This year, I want to take a moment to look back on what I’ve done.

First Half of the Year

In January, I started writing introductory posts about mixing techniques.
I’d been wanting to publish articles elsewhere, but after receiving rejections from various outlets, I decided to focus on writing consistently on my blog instead.

I lost count of how many times I revised those posts! Eventually, I submitted them to Kyobo Bookstore’s POD (Print on Demand) service. To my surprise, Joongpil Goo, an engineer from Klang Studio with extensive experience as an SM engineer, graciously wrote a recommendation for the book. Even now, it feels surreal! 😊

This was finally completed by late September, and it was quite an intense journey just to publish a single book.

From January to April, I worked with a studio called Studio Dolphin, producing YouTube videos where AI collaborated with indie musicians to create songs.
We used Soundraw for the AI-generated music, ChatGPT for lyrics, and melodies were composed by indie musicians. The challenge was to create a full song in just 90 minutes.

I participated as both an engineer and a panelist, but unfortunately, the videos didn’t garner much attention, and they’ve since been taken down.

At the start of January, I was extremely busy with various recording and mixing tasks for school projects. In February, I spent a lot of time preparing paperwork to apply for government-sponsored projects. Sadly, none of these applications were successful, which left me feeling rather deflated.

In March, I returned to school, and things got busier from there.

In May, I launched my English blog and started promoting Plugin Boutique products more actively, which kept me even busier.

Summer

From July to August, I worked on producing Danny Boy’s EP from start to finish.
I handled everything—recording, arranging, mixing, and mastering. 😊

At the same time, I collected measurement data for my thesis. The data turned out well enough that I’m now preparing to submit it to an international academic journal.

While processing the data, I found myself delving into coding—a field I never thought I’d explore! Surprisingly, tools like Copilot and ChatGPT were lifesavers. At first, I barely understood anything, but after asking countless questions, things started making sense. 😊

Second Half of the Year

September was tough. I applied for several positions but didn’t get any of them. My final interview was with the Gyeonggi Arts Center, but, well… things didn’t work out. Back in May, I’d also made it to the final round for a position at Kumho Art Hall at Yonsei University but was ultimately rejected. I guess that’s just how life goes. 😊

In October, I filmed a music video, and November passed without anything particularly noteworthy.

In December, I wrote a short paper about loudness in audio and submitted it to a domestic academic journal. It was accepted and will be published in early January.

Also, during this semester, a professor from Sorigeo joined the faculty, and I took his class. In collaboration with him, I gathered data for another research paper, spending two days on measurements. The data looks promising, but I haven’t organized it yet. Once I do, I plan to publish another paper and share the details. 😊

In addition to all this, I continued working on my own music, doing external mixing/mastering, composing/arranging, and providing guide vocals.

Unforgettable Projects

One of the most memorable projects this year was mastering the EP for the Bulkuksa Team’s Random Game. My favorite track was definitely “Microdust.”

A heads-up: the song contains explicit language. 😊

A friend had asked if I could master the track using only an MP3 demo, as they’d lost the original files. I was initially concerned about the sound quality but was blown away by how creative the music was. I couldn’t say no!

Some tracks were well-balanced, while others were completely off, but I managed to improve them significantly through proactive mastering. While the sound quality wasn’t ideal due to the limitations of MP3, the sheer fun of the music made up for it. 😊

Gear Purchases

  1. Stam Audio SA-4000 MK2 Compressor
  2. KEF Kube 15 MIE Subwoofer
  3. Stam Audio SA-2A Compressor
  4. Earthworks M30 Measurement Microphone
  5. Rack Cabinet and Patch Bay
  6. Wharfedale D310 Passive Speakers
  7. Cort A4 Bass
  8. A broken Heritage Audio Successor Compressor

I bought quite a bit this year…

Next year, I’m thinking of adding a tube microphone preamp and an EQ. Maybe another compressor or a mic too? The gear wishlist never ends! 😊
