That question messed with me for years.
I've been obsessed with audio since I was a kid. When it was time to pick a major, Audio Engineering wasn't really a choice, it was the only thing I could see myself doing. The first time someone in class asked me if I could identify which frequency just got boosted, I realized I had no idea. I'd been guessing my entire life.
The answer everyone gave me was the same: practice. So I did. Hours in my home studio, opening the DAW, EQing reference tracks, training my ears the slow way. Problem was, study load + assignments + work meant the practice time left over was tiny. And studio monitors aren't portable, I couldn't train on the bus, on lunch breaks, between classes. All that dead time was wasted.
I kept dreaming of something I could just pull out of my pocket. Plug in headphones, run a 5-minute round wherever I was, no DAW required. Couldn't find one I liked, so I started building it myself.
A few weeks later it shipped. It's called Freqy. I use it every day between sessions and the difference in my mid-range judgment has been honestly humbling. Turns out my ears were guessing way more than I thought.
Curious how others here got past this. Did you train with pink noise, real tracks, or something else? What actually moved the needle for you?
