Learn more↓An instrument that never stops
HumHerd is an always-on, collective tone. Everyone online picks a frequency between 40 and 1,000 Hz (or up to 20 kHz via manual entry). All those tones average into a single shared drone that shifts as people join and leave. It's a continuous, living sound shaped by real people humming live together right now. The collective frequency never stops as long as someone is here.
Every sound is generated live on your device in the moment you play it. No samples, no uploads, no streaming, no AI. Pure tones, zero latency. Free to use, no account required, no subscription. Just open the page and start humming.
What people use it for
Sleep and relaxation
Set a low frequency, enable delta wave binaural beats, layer in rain or ocean sounds, and drift off. The drone sustains indefinitely with no ads or interruptions. Works through silent mode on iPhone.
Focus and deep work
Many people use alpha wave entrainment (8-14 Hz) for concentration. Pick a comfortable tone, put on headphones, and use it as background audio for studying, coding, reading, or creative work.
Stress and anxiety relief
Theta wave brainwave entrainment (4-8 Hz) encourages deep relaxation. Combine it with a breath guide and ambient soundscape for a calming session you can run anytime.
Sound therapy and healing
Tune to specific solfeggio or chakra frequencies used in sound healing practices. Use HumHerd as a tone generator for vibrational therapy, or join a live sound bath with singing bowls and gongs.
Meditation and mindfulness
HumHerd's Zen mode turns your frequency into a drone meditation session. A sacred geometry mandala shifts with your tone, ambient soundscapes fill the background, and binaural beats guide your brain toward deeper states. Meditate alone or with a group in real time.
Binaural beats generator
Generate binaural beats targeting alpha waves (focus), theta waves (deep relaxation), or delta waves (sleep). The app creates a subtle frequency offset between left and right channels to encourage brainwave entrainment. Isochronic tones also available.
Group meditation online
Host a meditation room and guide a group through a shared soundscape. Everyone hears the same ambient layers and brainwave tones while their individual frequencies contribute to the collective. Meditate together with anyone, anywhere.
Soundscapes, brown noise, white noise
Layer in rain, ocean waves, forest ambience, crackling fire, cosmic drift, granular shimmer, or pure brown noise. Brown noise is the deep low-frequency hush popularized for ADHD focus and deep sleep. Session hosts can share soundscapes with the whole room. Works as a standalone ambient noise generator too.
Tinnitus relief
Identify the pitch of your tinnitus and play notched pink noise that masks the ringing while denying your auditory cortex input at that frequency. Research-backed approach (Pantev et al.). Find it in Practice → Vibe → Tinnitus relief. Headphones recommended.
Breathwork guide
Eight breathing patterns including box breathing, 4-7-8, and belly breath. A 4-count gets you settled before each session. The sacred geometry mandala expands on each inhale, holds, and contracts on each exhale, giving you a visual anchor that breathes with you.
Sound healing and frequencies
Tune to solfeggio frequencies, chakra tones, Schumann resonances, Tesla numbers, or any frequency that calls to you. HumHerd is a frequency generator with continuous control from 40 Hz to 1,000 Hz on the ribbon (or 20 Hz to 20 kHz manual). Land on traditional healing frequencies or explore the spaces between them.
Solfeggio frequencies
Schumann resonances
The Earth's electromagnetic resonant frequencies. Use binaural beats to target these or set your tone nearby.
Tesla and angel numbers
Nikola Tesla said "if you only knew the magnificence of 3, 6, and 9." Angel numbers and Tesla's 369 pattern show up across frequency healing traditions.
Fibonacci and golden ratio
Fibonacci numbers translated to Hz. Some practitioners use these for meditation rooted in natural mathematical patterns.
Online sound baths
Join a live virtual sound bath where a Shepherd plays singing bowls, gongs, crystal bowls, and chimes. The mandala reacts to each strike. Close your eyes and listen, or watch the sacred geometry respond in real time.
Tone and frequency generator
Use HumHerd as a pure tone generator for sound therapy, chakra balancing, vibrational healing, or instrument tuning. Slide to any Hz value, choose a waveform (sine, triangle, square, sawtooth), and sustain it as long as you need.
Music creation in your browser
Loom mode turns HumHerd into an online synthesizer, drum machine, and step sequencer. No downloads, no plugins, no accounts needed. Everything is rooted in the frequency you choose, and you can make music with others in real time.
Orb: radial instrument
A circular synthesizer wrapped around the mandala. Tap wedges to trigger notes with chorus, delay, and reverb. Expressive and immediate, like a touchscreen theremin crossed with a drum pad.
Pads: drum machine and tone grid
Tappable pads for drums and melodic voices. Pick from synth voices like warm sine, bell, pluck, saw, and square. Octave controls let you shift two octaves up or down from your root frequency.
Sequencer: step patterns
Build patterns with up to 32 steps across tone and drum tracks. Kick, snare, hi-hat, clap, plus melodic synth voices. Note extension for sustained tones and subdivisions for hi-hat rolls, snare drags, and triplets.
Loom: build a full song
The bar system lets you arrange sections into a complete song. Lock a bar, advance to the next, and build out your arrangement one section at a time. Copy patterns forward or start fresh. Play back bar-by-bar or loop the whole song. Solo or collaborative.
Jam sessions and collaboration
Start a multiplayer jam session and invite friends. Each person claims a track in the shared sequencer. Everything stays in sync across all players. Build music together from a shared root frequency, in real time, from anywhere.
Hive: democratic beat building
In Hive mode, the herd votes on each step of an 8-step sequencer. When enough people agree, a step activates. Nobody plans the beat alone. The collective rhythm emerges from the group.
How the sound works
Every note you hear is made on your own device in the moment you play it. Nothing is pre-recorded, streamed, or generated by AI. That's why there's no latency, nothing to download, and nothing stored on a server. The instrument is your browser.
Pure tones
Basic waveforms (sine, triangle, square, saw) plus processed voices (warm sine, bell, pluck, harp, lush, glow). Each voice has its own character: the bell rings, the pluck decays, the harp breathes with body resonance.
Shared space
All Loom instruments share a warm effects space: gentle chorus, stereo delay, and convolution reverb (from algorithmic to full cathedral). Percussion stays dry and punchy. The result feels like real instruments playing in a real room together.
Binaural and sub-bass
Brainwave entrainment uses dual slightly-detuned tones panned to each ear. Your brain perceives the difference. Sub-bass adds an octave-down layer tuned to your root for physical resonance. You feel it as much as hear it.
One clock, everyone
When you play together in a Loom or Hive, everyone shares the same beat clock. Your patterns lock to the herd automatically. Frequency data flows live between everyone online. The collective chord updates the instant someone joins, leaves, or changes their tone.
Sacred geometry visualization
A real-time audio visualizer and mandala generator that responds to everything happening in HumHerd. Your frequency, the collective, each instrument hit. Nine sacred geometry patterns morph and blend based on the tones being played.
Instruments trigger visual reactions. Kicks send shockwaves, snares scatter triangles, hi-hats sparkle, claps ripple the web, and tones bloom outward. Waveform shape changes the line style of the geometry. Motion trails smooth the animation for a meditative, psychedelic visual experience.
Cymatic mode: the geometry is the math
Switch from sacred geometry to cymatic visualization (Practice → Vibe → Mandala) and the mandala becomes the actual standing-wave nodal field at your current frequency, the same pattern that frequency would produce on a Chladni plate covered in sand. Each Solfeggio frequency renders a distinct mode: 174 Hz produces a six-fold snowflake, 528 Hz a five-petal star with two radial rings, 963 Hz a complex eight-fold field. Sit with a frequency and see what it actually does to matter.
A music and meditation community
HumHerd is built around shared experiences. Follow people whose tones and tracks you like. Add friends for quick room invites. Discover what others are making on the feed. Host persistent rooms that stay open for your community to drop into anytime.
Follow and discover
Follow other users to see their tracks in your feed. Browse public profiles and listen to what people are creating from their frequencies. One-tap follow, no approval needed.
Friends and rooms
Add friends for mutual connection. Friends show up as quick invites when you host a room. Run persistent meditation spaces, jam rooms, or hive sessions that your community can join anytime.
Share what you make
Record tracks from the sequencer and share them with a link. Share your current frequency as a card with a custom tagline and mandala render. Every shared link generates a dynamic preview image.
Streaks
Track your daily streak (consecutive days humming) and continuous streak (longest unbroken session). Build a practice. Shepherds leave a ghost tone in the collective for 24 hours after disconnecting.
Echoes at a frequency
Each Solfeggio frequency is a place with stories. Tap the ✶ glyph on any frequency card to open its echoes: anonymous, 140-character notes left by people who've sat with that tone. "174 after my dad died." "528 for the panic."The frequency stops being a number and becomes a place.
Two modes, one frequency
Everything in HumHerd starts from the frequency you choose. Zen is the meditation side. Loom is the music side. Switch between them anytime, and the mandala stays with you.
Zen
Contemplative mode. Drone meditation with sacred geometry, binaural beats, ambient soundscapes, and guided breathwork. The mandala expands and contracts with your breath. Tune to solfeggio frequencies, layer in rain or ocean sounds, and let the tone sustain.
Loom
Creative mode. Three instruments built around your root frequency: a radial Orb synth wrapped around the mandala, tappable Pads for drums and tones, and a step Sequencer for building patterns. Use the bar system to arrange sections into a full song, solo or with others.
Six session types
Host a room and invite anyone. Each session type shapes how participants interact. Some are contemplative, some are collaborative, and some are both.
Meditation
Guided group meditation with shared soundscapes and brainwave entrainment. Host controls the ambient layers while everyone contributes their tone to the collective.
Sound bath
One Shepherd plays singing bowls, gongs, and chimes. Everyone else listens and watches the sacred geometry respond. An immersive, live sound healing experience.
Jam
Multiplayer music collaboration. Invite friends, claim tracks in the shared sequencer, and build music together from a shared root frequency.
Convergence
Everyone picks a frequency, then all tones slowly pull toward the group average until they merge into one. A collective experience of unity through sound.
Hive
Democratic beat building. The group votes on each step of the sequencer. The beat emerges from collective agreement. Nobody controls it alone.
Loom
Collaborative songwriting, bar by bar. Everyone contributes to a shared arrangement. Lock bars, advance together, and build a complete song as a group.

Frequently asked questions
What is HumHerd?
HumHerd is a collective frequency instrument and meditation app. You pick a tone, it joins a shared frequency with everyone else online, and you can meditate or make music from that shared root. Every sound is generated live: no samples, no uploads, no AI. Just pure tones from real people in real time.
Who am I humming with?
Real people humming live, plus the occasional ghost tone: a tone a member leaves humming for the collective after they close the app. Nothing you hear is recorded, uploaded, or made by AI. To keep the space human, HumHerd quietly reads subtle signals from the way people interact, with no captcha and no sign-in wall to get in your way. It is designed to keep bots out, and the live counter only counts people humming right now.
Is it free?
The core experience is completely free. Pick a tone, join rooms, and use both modes (Zen and Loom) with no account needed. Signing up (free) lets you host rooms, save tracks, and build your profile. Shepherd ($7/mo) unlocks all synth voices, unlimited tracks, public rooms, sound bath hosting, and ghost tones (a tone that keeps humming for the collective for up to a day after you close the app).
Do I need to download anything?
No. HumHerd runs entirely in your browser. No downloads, no plugins, no MIDI setup. It works on any device: iPhone, Android, tablet, desktop. Add it to your home screen for a full-screen experience that keeps playing even when the phone is silent.
Does HumHerd listen to my microphone?
No, not unless you ask it to. The one mic feature is optional: tap the mic, hum a note, and HumHerd listens just long enough to find the pitch of your hum so it can tune your tone to match. Your browser asks permission first, the sound is analyzed on your device in the moment, and nothing is recorded, stored, or uploaded. The mic turns off as soon as your note locks in or you close it.
What are solfeggio frequencies?
Solfeggio frequencies are a set of tones used in sound healing and meditation practices. They include 396 Hz (liberation), 417 Hz (change), 432 Hz (harmony), 528 Hz (transformation), 639 Hz (connection), 741 Hz (intuition), 852 Hz (clarity), and 963 Hz (oneness). The frequency ribbon covers 40 to 1,000 Hz, and manual entry supports 20 Hz to 20 kHz.
How do binaural beats work?
Binaural beats play a slightly different frequency in each ear. Your brain perceives the difference as a third tone and tends to synchronize with it. HumHerd generates binaural beats targeting alpha waves (8-14 Hz, focus), theta waves (4-8 Hz, deep relaxation), or delta waves (0.5-4 Hz, sleep). Headphones are recommended.
Can I use HumHerd for sleep?
Yes. Set a low frequency like 174 or 285 Hz, enable delta brainwave entrainment, layer in rain or ocean soundscapes, and let it run. The tone sustains indefinitely. On iOS, add HumHerd to your home screen so audio plays through silent mode.
Can I use it for focus or studying?
Yes. Alpha wave binaural beats (8-14 Hz) are designed for focus and concentration. Pick a comfortable frequency, enable alpha entrainment, and use it as background audio while you work. No ads, no interruptions.
How do sound baths work?
In a HumHerd sound bath, one person (the Shepherd) plays singing bowls, gongs, and chimes while everyone else listens. The sacred geometry mandala responds to each instrument in real time. Participants watch the geometry react and feel the vibrations. Sound baths can be hosted live for groups online.
What is the collective frequency?
The collective frequency is the live average of every tone being played across all of HumHerd. It shifts in real time as people join, leave, or change their frequency. The mandala, orb, and audio all respond to it. It never stops as long as someone is humming.
How do I host a room?
Sign in, tap "+ Rooms" at the top of the screen, and pick a session type under "Start a session": Meditation, Sound Bath, Jam, Convergence, Hive, or Loom. You can name the room, set a fixed root frequency, and share the link with anyone. Rooms work on any device.
What makes the sound?
Every sound in HumHerd is generated live on your device: nothing pre-recorded, nothing streamed, nothing made by AI. You choose from pure waveforms (sine, triangle, square, saw) or processed voices (bell, pluck, pad, harp), and each one is literally made in the moment you play it. That's why there's no latency and nothing to download.
What is Hive mode?
Hive is a democratic beat-building session. Everyone votes on each step of an 8-step sequencer. When enough people agree on a step (40% threshold), it activates. The herd builds the beat together, one vote at a time. The result is a collective rhythm that nobody planned alone.
Does HumHerd have brown noise for ADHD focus?
Yes. Brown noise is in the soundscape picker (Practice → Vibe → Soundscape → Brown noise). It plays a steady, unchanging deep-low-frequency hush: no movement, no wobble, no reverb. Many people with ADHD find brown noise uniquely effective for sustained focus. Pair it with alpha-wave isochronic pulses (Practice → Brainwave → Pulse) for a focus stack that works through speakers.
Can HumHerd help with tinnitus?
It includes a tinnitus relief mode based on notched pink-noise therapy (Pantev et al.). You identify the pitch of your tinnitus by sliding a frequency control until the test tone matches what you hear, then the app plays soft pink noise with a notch filter cutting energy at exactly that frequency. The broadband sound masks the perceived ringing while your auditory cortex is denied input at that frequency. Find it in Practice → Vibe → Tinnitus relief. Headphones recommended. Not a medical treatment. See an audiologist for persistent tinnitus.
What is cymatics? What does cymatic mode do?
Cymatics is the study of how sound creates visible patterns in matter: sand on a Chladni plate, water in a cup. Each frequency produces a specific geometric pattern. HumHerd has a cymatic mandala mode (Practice → Vibe → Mandala → Cymatic) that renders the actual standing-wave nodal field at your current frequency. Sit with 528 Hz and see the same five-petal pattern that 528 Hz would produce on a vibrating plate. The visual stops being a metaphor and becomes mathematical truth.
What is the difference between A=432 and A=440 tuning?
A=440 Hz is concert pitch, the standard tuning reference for Western music since 1939. A=432 Hz is a healing-tuning subculture that argues the slightly lower reference produces a calmer, more resonant feel. HumHerd lets you choose either (Practice → Vibe → Tuning → A=432 / A=440). When set, your tone snaps to the nearest equal-tempered grid note for that reference. Default is "Free": any frequency you choose stands as-is, no quantization.
What is the difference between binaural beats and isochronic tones?
Binaural beats play a slightly different frequency in each ear. Your brain perceives the difference as a phantom third tone and tends to synchronize with it. Headphones required. Isochronic tones pulse a single tone on and off at the target frequency. No headphones needed, works through speakers. HumHerd offers both: Practice → Brainwave → Pulse (isochronic) or Beat (binaural). Both modes work with delta, theta, alpha, beta, and gamma presets.
How do I leave an echo at a frequency?
Sign in, open Practice → Browse, find a Solfeggio frequency card, and tap the ✶ glyph on the right side. That opens its echoes: anonymous notes, 140 characters max, one per hour, left by people who have sat with that frequency. The frequency becomes a place with stories: "174 after my dad died." "528 to sleep through panic." Read others, leave your own.
How does humming activate the vagus nerve?
Humming and chanting create vibrations that are thought to stimulate the vagus nerve, which governs your parasympathetic ("rest and digest") response. Slow exhales while humming a low tone are a favorite way to practice this. HumHerd is built around exactly that: pick a low frequency (174 Hz Foundation works well), enable a slow breath pattern (Practice → Breathe → 4-7-8), and let your hum match the tone. Even silently mouthing the hum while breathing slowly engages the same nervous system response.
