Rotates across rain, ocean, rivers, trees, birds, crickets, and night-insect beds where the current catalog fits the selected mood.
Sprint boost
Adds a denser pulse and stronger ambient layer for focus and deep-work sessions. Works best with headphones. No medical claims.
Lower values keep the bed natural. Around 8–16% is the sane range for most sessions; push it higher when you want to stress-test whether the modulation is actually audible.

Audio Modulation and Evidence
What ArgoBeat can measure in audio, and what it cannot promise about your brain
What ArgoBeat Is Trying To Do
ArgoBeat creates listenable music and ambient sessions that include target-rate audio modulation. In practice, that means rendered sessions can be spot-checked for a rhythmic marker near the selected mood frequency, without claiming a guaranteed listener response.
Human EEG activity is often discussed in these broad bands:
0.5–4 Hz
DeltaDeep sleep and very low arousal states
4–8 Hz
ThetaMeditation, REM sleep, creativity, introspection
GammaHigh-frequency activity associated with some attention and perception tasks
Some auditory-beat studies report effects on cognition, anxiety, pain, or EEG measures, but the evidence is mixed and individual response varies. ArgoBeat should be treated as a focus/relaxation audio tool, not a medical or therapeutic device.
Classic Beats vs. ArgoBeat's Current Approach
Feature
Binaural Beats
Target-Rate Audio Modulation
How it works
Two slightly different frequencies in each ear create a phantom beat frequency
Ambience is modulated directly, while music stays mostly clean with a lighter target-rate amplitude layer
Headphones
Required (must separate L/R channels)
Optional, though headphones can reveal stereo modulation more clearly
Sensation
Subtle and listener-dependent
Designed to stay listenable instead of sounding like test tones
Research
Studied, but findings are not uniform
Product QA verifies audio markers, not guaranteed brain response
Best for
Headphone-based experiments and personal routines
Everyday listening where musicality matters
ArgoBeat prioritizes listenable sessions first, then verifies target-rate markers in exported audio.

Everything runs in your browser's Web Audio API. Current sessions use curated music and ambient recordings, keep the music layer mostly clean, and apply most target-rate motion on the ambience side through a user-controlled wet/dry blend, plus compression and analysis on the final mix.

These papers informed the choice of broad audio target ranges and low-arousal content palettes, but ArgoBeat does not treat them as proof that any session will change EEG activity, mood, sleep, or performance for a specific listener.

The export analyzer can spot-check whether a recording contains an audio marker near the selected target. That is QA for the audio file, not a clinical claim about listener response.
The deployable nature catalog is broader than just water loops: current beds include coast birds, forest birds and branches, night crickets/cicadas, rivers and streams, rain, gongs, and singing bowls. Jungle content exists in the broader catalog, but not every branch or deployment ships the same subset.
Why ArgoBeat is Free
Unlike services that synthesize every session on paid servers, ArgoBeat plays curated static audio files and applies lightweight modulation directly in your browser using the Web Audio API.
$0
Server-side synthesis
No per-listen synthesis jobs - curated audio assets are reused at playback time
$0
Server compute
Playback shaping runs in the browser via Web Audio API, not on a per-listen compute backend
$0
Databases or accounts
No sign-up or server-side user accounts; preferences stay in local browser storage
Low
Incremental cost
Hosting and audio delivery still cost something, but reuse keeps marginal playback cost low
ArgoBeat is hosted on Cloudflare Pages and serves audio from Cloudflare-hosted storage/edge delivery. Reusing curated tracks and soundscapes keeps runtime cost low while still allowing a broad catalog.
