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 tones being played 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 AI audio generation. The shared collective is free and needs no account. Shepherd adds expanded rooms and creative tools, but anyone can open the page and start humming.
What people use it for
Sleep and relaxation
Set a comfortable low tone, choose a slow pulse if you enjoy one, layer in rain or ocean sounds, and use the session timer as you settle. No ads or interruptions.
Focus and deep work
Pick a comfortable tone, steady brown noise, or a subtle pulse and use it as uninterrupted background audio for studying, coding, reading, or creative work.
Calm and decompression
Combine a gentle pulse with a breath guide and ambient soundscape for a quiet session you can return to anytime.
Sound practice and ritual
Explore solfeggio and chakra-frequency traditions as reflective prompts, use HumHerd as a flexible tone generator, 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 geometric mandala shifts with your tone, ambient soundscapes fill the background, and optional beat or pulse textures give you another rhythm to rest attention on. Meditate alone or with a group in real time.
Binaural beats generator
Generate binaural beats at pulse rates commonly labeled alpha, theta, or delta. The app creates a subtle frequency offset between left and right channels. Isochronic pulse tones are available too. Responses vary, and the labels are not promises of a particular mental state.
Group meditation online
Host a meditation room and guide a group through a shared soundscape. Everyone hears the same ambient layers and pulse 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 gives you a steady low-frequency hush. Session hosts can share soundscapes with the whole room, and each soundscape also works on its own.
Tinnitus listening mode
Match a perceived pitch and shape soft pink noise with a notch around it. This is optional comfort tooling, not treatment, and research on notched sound is still mixed. Keep the volume low and talk with an audiologist about persistent tinnitus.
Breathwork guide
Eight breathing patterns including box breathing, 4-7-8, and belly breath. A 4-count gets you settled before each session. The mandala expands on each inhale, holds, and contracts on each exhale, giving you a visual anchor that breathes with you.
Sound traditions and frequency tools
Tune to solfeggio frequencies, chakra tones, Schumann resonances, number patterns, or any frequency you want to explore. 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). Traditional names and associations are offered as cultural and reflective context, not as medical effects.
Solfeggio frequencies
Schumann resonances
Schumann resonances are electromagnetic frequencies measured between Earth's surface and the ionosphere. HumHerd can use the same numbers as audible pulse rates, but it does not reproduce Earth's electromagnetic field.
3-6-9 patterns and angel numbers
These number patterns appear in contemporary spiritual and numerology practices. HumHerd offers them as tuning prompts, not scientific effects.
Fibonacci and golden ratio
These presets use Fibonacci numbers directly as Hz values. It is a creative mapping for listening, not a natural acoustic law.
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 meditation, sound practice, frequency exploration, or instrument tuning. Slide to any Hz value, choose a waveform, 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. Save 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. A tap does not wait for streamed audio before making sound, and raw audio is not stored on a server. The instrument runs on your device.
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.
One sound space
Loom instruments share gentle chorus, stereo delay, and room reverb so they feel like part of one mix. Percussion stays clear and direct.
Binaural and sub-bass
Binaural mode uses slightly detuned tones panned to each ear, creating the perception of a rhythmic difference. Sub-bass adds an octave-down layer tuned to your root for deeper resonance.
A shared beat
When you play together in a Loom or Hive, everyone shares the same beat clock. Patterns stay aligned while the collective chord follows people joining, leaving, or changing their tone.
Geometry that moves with the sound
The mandala responds to your frequency, the collective chord, and each instrument hit. Nine geometric patterns morph and blend as the sound changes.
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
Cymatic mode is a Chladni-inspired mathematical visualization. Your frequency selects and blends modeled nodal patterns, so each part of the range has a different symmetry. It is an artistic simulation, not a physical measurement of a plate or room.
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 a geometric mandala, 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 optional pulse tones. The host controls the ambient layers while everyone contributes their tone to the collective.
Sound bath
One host plays singing bowls, gongs, and chimes. Everyone else listens and watches the mandala respond.
Jam
Invite friends, claim instruments in the shared sequencer, and build a loop from one root frequency.
Convergence
Everyone picks a frequency, then all tones slowly pull toward the group average until they meet.
Hive
The group votes on each step of the sequencer. A step turns on when enough people choose it.
Loom
Build a song together, one bar at a time. Save a bar, move to the next, and keep arranging as a group.

Frequently asked questions
What is HumHerd?
Pick a tone and HumHerd blends it with the tones other people are playing. Sit with the shared sound in Zen, or turn your tone into loops and songs in Loom. Every sound is generated live on your device, with no samples, uploads, or AI audio generation.
Who am I humming with?
Live participants, plus the occasional ghost tone: a tone a member leaves humming for the collective after they close the app. Nothing you hear is recorded or uploaded, and HumHerd does not offer AI audio generation. 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 excludes ghost tones.
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 for free lets you host rooms, save tracks, and build your profile. On the web, Shepherd is $7/mo or $49/yr at the founding price. It unlocks all synth voices, a much larger public loop catalog, advanced room hosting, sound bath hosting, and ghost tones, which keep humming for the collective for up to a day after you close the app. Your Shepherd membership follows your HumHerd account.
Do I need to download anything?
No. The web app runs in a modern browser with no plugins or MIDI setup. You can use it on iPhone, Android, tablet, or desktop, and adding it to your home screen gives you a full-screen experience.
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 tones used in some meditation and sound-practice traditions. People associate them with themes such as change, connection, or clarity, but those associations are reflective prompts rather than proven medical effects. 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, creating the perception of a rhythmic beat at the difference between them. Some people use them as a meditation or focus aid, but responses vary and the evidence for specific outcomes is mixed. Headphones are required for the binaural effect.
Can I use HumHerd for sleep?
Yes. Set a comfortable low tone, choose a slow pulse if you enjoy one, layer in rain or ocean soundscapes, and use the session timer as you settle. Keep the volume low enough for extended listening.
Can I use it for focus or studying?
Yes. Pick a comfortable tone, brown noise, or a gentle pulse and use it as uninterrupted background audio while you work. Some people find steady sound helpful for focus, but HumHerd does not promise a particular cognitive effect.
How do sound baths work?
In a HumHerd sound bath, one host plays singing bowls, gongs, and chimes while everyone else listens. The mandala responds to each instrument in real time, giving the group a shared visual focus.
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 is pre-recorded, streamed, or made by AI. Choose a basic waveform or a shaped voice such as bell, pluck, pad, or harp. Since the instrument runs locally, a tap does not wait for streamed audio before making sound.
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 focus?
Yes. Brown noise is in the soundscape picker. It plays a steady, deep hush with no movement or reverb. Some people prefer it as background sound while working or reading. HumHerd does not treat ADHD or guarantee improved focus.
Can HumHerd help with tinnitus?
HumHerd includes an optional tinnitus listening mode that lets you match a perceived pitch and shape soft pink noise with a notch around it. Some people use shaped sound for temporary listening comfort, but this is not a medical treatment and results vary. Keep the volume low, stop if symptoms worsen, and see an audiologist for persistent tinnitus.
What is cymatics? What does cymatic mode do?
Cymatics is the study of visible patterns formed when sound vibrates matter, such as sand on a plate. HumHerd’s cymatic mandala is a responsive mathematical visualization inspired by standing-wave patterns. It reacts to your frequency, but it is not a physical simulation of a particular plate, room, or material.
What is the difference between A=432 and A=440 tuning?
A=440 Hz is the common concert-pitch reference in Western music. Some listeners prefer the slightly lower feel of A=432 Hz, though it has no established healing advantage. HumHerd lets you choose either reference. The default Free setting preserves any frequency you choose without snapping it to a tuning grid.
What is the difference between binaural beats and isochronic tones?
Binaural beats use a slightly different tone in each ear so you perceive a rhythmic difference between them, which requires headphones. Isochronic tones pulse one audible tone and work through speakers. HumHerd offers both as optional listening textures with delta, theta, alpha, beta, and gamma labels. Those labels describe pulse rates, not guaranteed mental states.
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.
Why hum during meditation?
Humming gives a slow exhale a sound and a physical sensation you can follow. Many people find that grounding, especially with a comfortable low tone and an unforced breath pattern. HumHerd supports the practice without claiming that humming activates a particular nerve or treats a health condition.
