Binaural / entrainment candidate pool — stress-relief "Music" tracks (2026-07-02)

Candidates for evolving the Music audio option into a stress-relief set of binaural-beat / brainwave-entrainment tracks that crossfade between each other (not a single loop). Operator brief: "binaural beats for stress relief."

All 11 below are CC0 (public domain — no attribution legally required; we credit anyway as courtesy), all stereo, all sourced from freesound.org and license- verified by fetching each page. Review gallery (gitignored, local-only, like review_audio.html): simulator/static/review_binaural.html → open /review_binaural.html with the sim server running. It streams each track's public HQ preview so you can audition + tick keepers.

Caveats (operator, read before picking)

  • True binaural (#1–7) needs headphones. The beat is the L/R frequency difference, so on speakers it collapses to a steady carrier tone (no entrainment). #8–11 are ambient sub-bass / pulsing drones that keep the calm feel on speakers.
  • Band coverage: heavy on delta (0.5–1.5 Hz) + one clean theta (4 Hz, #2). No CC0 alpha (8–12 Hz) track surfaced — widen to CC-BY (FMA/ccMixter) if wanted.
  • No clean CC0/CC-BY isochronic or monaural (the speaker-correct entrainment type) was found — every hit was NC/SA or unlicensed (see rejects). For speaker playback, lean on #8–11 for the "beat" feel.
  • Previews vs originals: the cdn.freesound.org/…-hq.mp3 URLs are public streamable previews (verified live, HTTP 206). The originals (WAV/AIF/full-MP3) need a free freesound login; CC0 permits self-hosting, so for keepers download the originals and host on R2 — do not hot-link the CDN in production.

Rejected / could not verify

  • archive.org "Binaural Beats – Alpha/Beta/Theta/Delta" & "Isochronic Tones & Binaural Beats Combined" (loopool / Jean-Paul Garnier) — CC BY-NC-SA 3.0 (NC). The most promising isochronic set — rejected for the NC clause.
  • archive.org "Om Alpha Brainwave Entrainment Loop" (Entraino / KS Chauhan; freesound chauhans/100370) — CC BY-NC 3.0. Rejected (NC).
  • archive.org "1hr 30 Min Theta Binaural Beat (7 Hz)" (Chari G) — no license shown. Rejected (unverifiable).
  • freesound "deadthetawaves.wav" (NoiseCollector/43295) — license fine (CC BY 3.0) but "evil sounding loop of the living dead" — rejected for fit, not license. Back pocket only if an unsettling deep-scale track is ever wanted.
  • TunePocket / dialedggsound / miraclefrequencies / audio.com "Theta 7Hz" — "royalty-free"/commercial pages, murky redistribution, no per-track CC license.

Next

Operator auditions review_binaural.html, ticks keepers (Copy picks). Then we wire the playback: the Music source becomes a multi-track set that crossfades between the kept tracks (architecture decision — replace vs. join the ethereal loop — deferred to that step; see audio-music-option).
