Carrier Frequency Explained: The Base Tone

In the context of binaural beats, the carrier frequency is the base pitch played in one ear. It is the 'vessel' that carries the difference frequency to the brain. While the beat frequency determines the brainwave state, the carrier frequency affects the volume and quality of the perceived tone.

How Carrier Frequencies Work

The carrier frequency is typically a sine wave in the audible range (usually between 200Hz and 1000Hz). The brain perceives the difference between the left and right carrier frequencies as the beat frequency. For example, a 400Hz tone in the left ear and a 410Hz tone in the right ear creates a 10Hz theta beat.

Choosing the Right Carrier

While the beat frequency dictates the state (Delta, Alpha, Beta), the carrier frequency is often chosen for comfort. Higher frequencies can sometimes be perceived as louder or harsher. Binaura allows users to adjust carrier layers, offering a balanced or dark sound profile to ensure the audio is pleasant to listen to.

Advanced Stacking with Binaura

Advanced users can stack multiple carrier frequencies to create complex soundscapes. Binaura supports up to three carrier layers, allowing you to layer different base tones while still maintaining a distinct beat frequency. This is useful for creating rich, multi-layered audio experiences for meditation or focus.

FAQ

No, the effect is determined by the difference (beat frequency), but the carrier affects the volume and timbre.

Yes, in Advanced Mode, you can adjust the carrier frequency to suit your listening preference.

There is no single standard, but frequencies around 200Hz to 600Hz are commonly used.
