Do I need headphones to use Sigfre?
No. Because Sigfre uses monaural beats and isochronic tones instead of binaural beats, it works on any speaker, not just headphones. Binaural beat apps are locked to stereo headphones. Sigfre plays anywhere.
Is Sigfre's audio AI-generated?
No. Every track is crafted by a human producer with over 20 years of experience. No algorithm. Every layer is intentional.
