This is honestly such a weird and interesting idea 😄 I actually have the same question about how practical it ends up being once you use it for more than a few minutes, because the concept is really creative. The combination of sound frequencies, Morse code, and text editing feels chaotic in a fun way, but also strangely experimental and artistic at the same time.

I’m also curious how accurate and responsive the translation is, especially when things get noisy or when typing faster. It almost feels like a Morse code audio translator pushed into abstract territory taking raw audio signals and continuously trying to interpret them into meaningful text in real time. That’s what makes it so fascinating: it sits somewhere between a communication tool, a coding experiment, and a piece of interactive art. Projects like this are fun because they explore communication in such an unconventional way, and I’d love to know what inspired you to build it in the first place. Definitely feels like one of those “this shouldn’t work, but somehow it does” kinds of projects.

Thank you for the kind words 😄

The accuracy mostly depends on your microphone quality and how noisy your environment is. I tried to make it more adjustable through the config file, where you can change the tolerance settings. If I remember correctly, the default tolerance is around ±5 Hz (though I might be wrong 😅).

Faster typing is technically possible — it only needs around 200 ms to detect a frequency,  but I honestly wouldn’t recommend it. I tried typing quickly myself and it was pretty painful.

And yeah... you’re right, it probably shouldn’t work, but somehow it does. I was mostly just bored, and when I’m bored I tend to build weird stuff like this.

The main inspiration was a video by Code Bullet where he recreated Guitar Hero using an actual guitar and used frequencies to control his mouse and type. That video basically made me think: “what other dumb but interesting thing could I build with frequencies?” 😄

If you want, here is that video.
