Telemetry

My breakthrough: I asked what an mp3 is. An array of numbers that pushes air, every second. Then I asked what the eye sees. Only 2D. The brain guesses the shadows and the shapes.

Telemetry is the world read as numbers. Sound, images and text all arrive as arrays, and I build the systems that turn them into decisions. Music and OCR are my passions, so most of this started as a challenge I set myself, and the best of it went to production.

Lane 01 · Sound

Air pressure, sampled. Everything else is features.

A song, a voice or a full room is one long array. I cut it into frames, extract what the ear and the room care about, compress it and let the structure show itself.

01wave

the raw array, live or recorded

02frames

short windows, noise filtered

03features

100+ DSP features per frame

04PCA

the few directions that matter

05KMeans

moments that sound alike

06decide

similarity scored, acted on, evaluated

productionlive venue

A room that listens

Real-time crowd detection in a live venue, by filtering for voice frequencies, then 100+ features through PCA and KMeans into similarity scoring. It adapts while people are in the room, and a continuous evaluation loop checks it in production.

The DJ booth as a recommender

Python systems that turn tracks into structured feature spaces for real-time, context-aware music decisions, with cover art alongside the signal for a richer picture of a song. Behind the decks it runs live: sequencing, energy progression, and the floor as the feedback loop.

Lane 02 · Vision · OCR

We only see 2D. The rest is a guess, so I teach the machine to guess well.

An image is a grid of numbers, the same way a song is a line of them. OCR is where vision meets language: find the text, read it, and give it back a shape a database can hold. It is a passion of mine, and the projects are coming to this page.

Lane 03 · Language · NLP

Text is the messiest signal of all.

Scraped pages, spreadsheets and documents come in broken. I clean them, cut them into pieces a model can quote, and build retrieval and agents on top, with telemetry on every step so I can see what it did.

the web and the files

02clean

The sound playground

Twenty tracks. Every one a challenge I set myself.

Where sound goes once you can read it. I built each of these to learn the edge of it, not for a client. Press play anywhere.
