Brainwaves
Read full descriptionHide full description
Silence is too loud. Music is too distracting. Brainwaves is the focus tool for the brain in between. Compose your own multi-stage session across delta, theta, alpha, beta and gamma. Pick the tone type. Layer the sound. Save it. Studio audio you can actually hear the difference in. WHAT YOU GET • Start from 90+ presets, including 28 multi-stage journeys. Or compose your own from scratch. Pick the frequencies. Set the durations. Save it. Run it tomorrow. • Four tone types. Binaural beats, isochronic tones, monaural beats, or combined. Use whatever fits your setup. • Five brainwave states. Delta for sleep. Theta for meditation. Alpha for unwinding. Beta for focus. Gamma for energy and recall. Fine-tune the frequency inside any of them. • Layer the whole thing. 33 soundscapes with cinematic visual backdrops. 49-track music library. Independent volume on every layer so the mix is exactly yours. • Studio-quality audio. ±0.01 Hz precision. Under 0.001% THD. Listenable for 90 minutes without ear fatigue. • Universal across iPhone, iPad and Mac. One purchase covers all three. Sessions, presets, settings and listening history sync across every device. WHO IT'S FOR If you've cycled through lofi, brown noise, a Brain.fm trial and a Calm week and bored your brain in ten minutes, this holds up at minute 45. Multi-stage means theta into alpha into gamma, not the same loop on repeat. If you wind down at night and brown noise isn't doing it, the delta sessions are built for the brain that can't shut up at 11pm. If you meditate but find guided practice patronising, theta and alpha give you the substrate without the script. Terms of Use: https://resonatelabs.app Privacy Policy: https://resonatelabs.app
