Frequency Lab
Explore Solfeggio tones, ambient audio and a customizable binaural beat generator. You can also switch to Independent Ear Control to choose a completely different frequency for the left and right ears.
Traditional meanings are often associated with specific frequencies, but individual experiences vary. This is a recreational listening and experimentation tool, not a medical treatment, diagnosis, or substitute for professional support.
Embedded video previews are provided by YouTube and may connect to that service when loaded. Its privacy practices and terms apply to those previews.
Simple, consistent tones without additional music or ambient sounds.

A lighter collection of tones with an atmospheric style. “Angelic” describes the theme of the recordings rather than a scientifically defined class of frequencies.

In standard binaural mode, one tone is sent to the left ear and a slightly different tone is sent to the right ear. The difference between those tones is the binaural-beat frequency. Independent Ear Control lets you choose both ear frequencies separately.
Use stereo headphones for channel separation and the intended binaural effect. Keep the volume comfortable. If any tone feels uncomfortable, lower the volume or stop playback.
Choose a preset or create your own difference below. Preset names describe common listening uses rather than guaranteed effects.
Choose a starting tone or set any custom carrier from 80Hz to 1000Hz. In standard binaural mode, the right ear is automatically calculated from this carrier plus the beat difference.
Turn this on to choose a completely separate frequency for each ear. For example, you can send 174Hz to the left ear and 528Hz to the right ear.
Tone sent to the physical left stereo channel.
Tone sent to the physical right stereo channel.
When the tones are close together, their numerical difference is the binaural-beat difference. If you choose frequencies that are far apart, the generator is simply playing two independent stereo tones. This tool does not claim that particular frequencies diagnose, treat, cure, prevent, monitor or manage a health condition.
Left 220Hz • Right 228Hz
Layer generated ambient sound underneath the stereo tones. Every layer can also be adjusted individually.
Mix multiple generated background sounds together. Changes happen live while the generator is playing.
While the generator is playing, use Left and Right to confirm your stereo channels. Return to Both for normal binaural or independent-ear listening.

Binaural beat, stereo tone and soundscape labels describe listening formats and common terminology. They are not medical treatments and individual experiences can differ.
