**A place to meet sound, without maps** Facilitated by **Vesti Gium (they/them)** Everyone enters as they are. No score. No threshold of skill. We follow the room, moment by moment— listening, nudging, letting the music find itself. A breath, a shoelace, a laugh, a footstep— each carries weight. Silence is welcomed; noise is celebrated. There are no wrong directions here. We practise a listening that reaches outward and inward: to ourselves, to one another, to the space we shape together. That is where the music begins. * 🌀 Bring a voice, an object, an instrument, a movement—or nothing at all. * ✨ **Priority given to FLINTA folks and people with migration backgrounds.** * 🎧 No experience needed.

On the 1st of July we will host the next iteration of our monthly Audio Developer Meetup where **Peggy Sylopp** from [sinceare](https://www.sinceare.com/) will be presenting her work on personalization approaches for hearables, and **Vlad Litvinenko** will demo 'Spotykach', a looping playground. See below for details! As always, there will be a chance to network over drinks and pizza. Anyone interested in Audio development is welcome! Doors open at 18:00, talks start at 18:15. Please note: Attendance is **strictly limited** to people who have RSVP'd. Talk details: **Can users train their own audio system?** \- Peggy Sylopp In this talk, we present Sinceare’s closed-loop personalization approach for hearables. Instead of relying on predefined fitting rules or static presets, users teach the system how it should sound through interaction and feedback. These preferences are transformed into personalized machine-learning models that learn how to control existing audio processing algorithms according to individual preferences. Rather than replacing audio DSP algorithms, the generated models act as an adaptive control layer that continuously adjusts algorithm parameters based on user-specific listening preferences. Based on more than eight years of research and a recent study conducted with Fraunhofer IDMT and Charité, we will share insights into user-driven audio model generation, human-in-the-loop machine learning, and the path from research prototype to future embedded hearable deployment. **Spotykach, a looping playground** \- Vlad Litvinenko Vlad is a Berlin based software developer doing e-commerce by day, bleeping machines at night and sometimes music in between. The talk is about device they’ve recently built. It’s “Spotykach”, a looping playground, as they call it. It started from an attempt to do a simple Beat-Repeat kind of plugin, but then evolved into a community project within Synthux Academy with people from different backgrounds and countries.

**This is 100% non-profit. The 15€ sign up fee for everyone is only to minimize last-minute cancellations. The total sum goes to a bar-tap that everyone can use to order drinks until the amount is used up. ‼️NO REFUNDS‼️** **‼️Please don't just show up without RSVPing here and paying the 15€. We have a separate room that has limited capacity and a specific drinks agreement with the bar - so splitting up the bill won't become a mess.‼️** **Small update on how your money get's used from May 2024 onwards:** As of this month, meetup.com has started charging me 34€ instead of 16€ per month. I've decided to distribute this fee evenly among all us participants every month. Example: In the last 12 meetups, the average number of attendees was 17. With 17 attendees I would effectively collect 230€ (after fees). I would now substract 34€ leaving us with 196€ that go to the bar. 15% get's tipped to the wait staff, in this case 30€, leaving us with 166€ effectively to order drinks. Hope everyone is cool with this system. :) Website: https://www.pberg-engineers.me WhatsApp groups: Please come and join us on WhatsApp! \- "PBerg Engineers \- NEWS" \- Only organizers can post announcements or polls \-\> https://chat\.whatsapp\.com/EqMJMmlCZO6LOOfAoG4yTj \- "PBerg Engineers \- DISCUSS" \- Everyone can post \-\> https://chat\.whatsapp\.com/LPuo76J83gF6IZMLUcM4u2 Please join those groups now if you're interested. :) All skill/education-levels welcome! :) Lightning Talks: \- TBD We'll also have a brief "Jobs: Lost & Found section". **Location:** From the street you will have to enter the right hand Cafe Chagall (yes, there are 2).

Most brands track whether they appear in ChatGPT, Gemini, and AI Overviews. But mentions and citations only tell half the story. In this session, Raoul Schreck, our CEO at Buzzmatic will show you how to systematically analyze what AI actually says about your brand: which attributes it assigns to you, which USPs it credits to your competitors, and where your communicative blind spots are. Using a real client case and a concrete 4-layer framework, you’ll learn how to move beyond visibility tracking and uncover the narratives AI systems are building around your brand — and what to do about them the next morning.

Monthly working lunch for Columbus business owners. One specific topic, one to three actions you can run this week. You can be the best at what you do and still be invisible. If local buyers cannot find you, the phone does not ring. Marketing Monday Lunch + Learn is a monthly working lunch for Columbus business owners focused on building relationships, local networking, and local marketing. Every kind of local business welcome. No pitch round, no pressure, no upsell. **This month** Most local businesses pick one or two places to be visible and call it good. The result is inconsistent calls and a feeling that marketing is not working. We will walk through the three places every local business needs to show up, plus the fourth place most owners ignore that quietly produces the warmest leads. **What to expect** Doors open at noon. Order lunch and drinks at the cafe counter or bring your own. You get real conversation with other local owners and a focused marketing lesson. You leave knowing people and with one to three actions to run that week. The room is reserved through 1:30 PM. **Who this is for** Any local business owner who wants clearer marketing direction and real local relationships. Service businesses, retail, home services, professional services, online owners building local presence, anyone serious about being part of the Columbus business community. **Not the right fit if** You are here to pitch the room or recruit for an MLM. **Details** * Second Monday of every month * 12:00 to 1:30 PM * Good Cafe Easton, 4400 Easton Commons, Ste 150, Columbus, OH 43219 * Order lunch and drinks at the counter when you arrive * Free to attend, RSVP required, space is limited **About the host** Rita Suzanne is a local marketing strategist and the founder of Local Marketing Method.

**Practical Curiosity: Learning from Everyday Data** How do we actually get better at utilizing our day-to-day data? Fancy dashboards and complex models might look nice and draw attention, but that’s not where most of us spend our time. In fact those shiny outputs frequently sit unused, while the real insights are drawn from the analyst’s daily practice. Sometimes it’s as simple and as powerful as noticing that a segment is shrinking, a channel is underused, or certain links keep getting all the clicks. There’s many different places that the spark of insight can come from, but you have to keep your head in the data and know where to look. In this session, we’ll explore real-world examples of how segmentation, testing, and click behavior can uncover practical digital marketing opportunities. You’ll leave with inspiration for your own use cases, along with a few simple ways to ask better questions, spot meaningful patterns, and make smarter decisions without overcomplicating it. **About Our Speaker:** [Elaine Armbruster](https://www.linkedin.com/in/elainearmbruster/) is a Director of Digital Experience at the [American Diabetes Association](https://diabetes.org/), where she focuses on using data and insights to create smarter, more effective digital experiences. A lifelong Columbus resident, she has built her career in email marketing and the broader digital user journey, and is finding she most enjoys working in the messy middle where systems, data, and big ideas don’t quite line up yet.

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

You can sleep in on the Sesquicentennial (observed), we’re shifting to the following Friday. But join the local UX community for a chat and some biscuits to catch up. If you were in CA for Figma Config, tell us all the lines and you can tell me how I can animate an SVG without coding it by hand, and why I’d even want to. Thanks to the team at Nationwide of supporting the group.
