About this app
Quantify the vibe.
You've walked into a room and tried to put the feeling into words — "this place has a nice energy", "it's too dead in here", "I can't focus, it's chaotic". Humm turns that gut feeling into a number you can act on and share.
Tap Listen. For four seconds, Humm records a fragment of the air in front of you, runs it through a Rust DSP core to pull four acoustic signatures — Volume, Pulse (transient density), Brightness (spectral centroid) and Chaos (spectral entropy) — and then translates those four numbers into a single 0–100 score under the mode you care about:
• Focus — quiet, steady, non-voice, low-chaos rooms score high. Built for deep work, study, coding, reading.
• Party — loud, busy, broadband, bright rooms score high. Built for events, gigs, packed rooms, hype checks.
The result lands as a generative aura — a living shape whose colour, size, jaggedness and pulse all move with the metrics. No two rooms look the same.
Why you'll keep it on your phone:
• Settle arguments. "It's too loud in here" — is it though? Humm gives you the number.
• Scout study spots. Walk into a library / café / co-working space and know in 4 seconds whether it'll actually work.
• Tell the story of a night. The aura from a quiet 6pm bar vs a packed 1am club are visually unmistakable.
• Share it. One-tap Add to Insta Story posts your aura with the score and the four metrics baked in. Generic share works to anything else.
How it works:
• Sources cited inside the app under "Why this score?".
Privacy first!
• 100% offline. No accounts. No login. No cloud. No analytics.
• The microphone buffer lives in volatile RAM for the duration of the analysis (~4 seconds), then it's gone. We never write the audio to disk, and we never send it anywhere.
Built for old phones too, to ensure no one gets left out from the fun!
Try it. Share your weirdest room. #ShareTheHumm
