About Free Sound Machine

Free Sound Machine is a free, browser-based audio tool designed to help you focus, relax, meditate, and sleep better. Our platform offers two powerful sound generation tools that work entirely in your web browser - no downloads, no installations, and completely free to use.

What We Offer

🎵 White Noise Generator

Our noise generator creates six different types of algorithmically-generated noise in real-time:

  • White Noise: Equal energy across all frequencies - perfect for masking background sounds
  • Pink Noise: More natural-sounding with emphasis on lower frequencies - great for relaxation
  • Brown Noise: Deep, rumbling sound with strong low-frequency emphasis - ideal for sleep
  • Blue Noise: Crisp, bright sound with high-frequency emphasis - excellent for focus
  • Violet Noise: Sharp, bright sound with strong high-frequency content - perfect for masking high-pitched sounds
  • Grey Noise: Psychoacoustically balanced for equal perceived loudness across all frequencies

All noise is generated in real-time using advanced Web Audio API algorithms - no pre-recorded files needed!

🧠 Binaural Waves Generator

Our binaural waves generator creates brainwave entrainment frequencies designed to help you achieve different mental states:

  • Delta Waves (1.5 Hz): Deep sleep, healing, and regeneration
  • Theta Waves (6 Hz): Deep meditation, creativity, and REM sleep
  • Alpha Waves (10 Hz): Relaxation, light meditation, and calm focus
  • Beta Waves (18 Hz): Relaxed focus, active thinking, and alertness
  • Gamma Waves (50 Hz): High focus, cognitive processing, and peak performance

Customize both the base frequency and beat frequency to create personalized brainwave entrainment experiences. Works best with headphones!

Pink or brown noise combined with alpha or theta binaural waves can enhance meditation practices and help you achieve deeper states of relaxation.
