## What is Solfeggio Mixer?

You can find plenty of Solfeggio music and healing audio tracks on video streaming sites, but it’s hard to tell if they actually produce the frequencies you’re looking for, isn’t it? Plus, most of them are just boring. With this app, you can reliably combine multiple frequencies tailored to your needs at any given moment and listen to them while playing music or videos. Since it uses binaural technology to generate fluctuations like alpha waves and Schumann resonance, using headphones or earbuds is most effective. Please adjust the volume so that the sound is low enough not to interfere with your music.

For example, during meditation, you can use 174Hz + 963Hz + 4096Hz + theta waves; for sleep, the highly therapeutic 285Hz + 396Hz + 528Hz + delta waves; and when you want to focus on studying or work, 432Hz + 741Hz + 852Hz + Schumann resonance—you can create various combinations to suit the situation. In addition to a total of 11 frequencies, there is a mode modeled after a singing bowl. However, on older iPhone models, enabling too many frequencies at once may cause noise. If this happens, please reduce the number of frequencies you mix.

You can use all features during the 10-day free trial period. Even during the trial, you can purchase a lifetime license at any time using the button at the bottom of the screen. Please scroll down if it is hidden.

Feature Description:
- You can synthesize the following Solfeggio frequencies:
    174Hz: Expansion of Consciousness
    285Hz: Natural Healing Power
    396Hz: Release from Anxiety
    417Hz: Embracing Change
    528Hz: Love, Miracles, DNA Repair
    639Hz: Harmony from Conflict
    741Hz: Improved Expressiveness
    852Hz: Enhanced Intuition
    963Hz: Higher-Dimensional Consciousness
    432Hz: Stress Relief & Focus
    4096Hz: Angelic Frequency
    Bell: Singing Bowl Mode

- In Singing Bowl Mode, up to three harmonics (2.7x, 4.3x, 5.8x) of the active frequency are synthesized. Since the Angel Frequency is a high-frequency sound itself, Singing Bowl Mode is disabled for it.

- Tap the waveform display to view a list of frequencies, allowing you to select a frequency while confirming its effects.

- Tap the “i” button to display the frequency details dialog. Details are displayed one item per page, so swipe horizontally to find the item you want. The latter part also includes explanations of Schumann resonance and delta to gamma waves.

- The left-right phase difference (modulation) can be set from 0 to 50 Hz in 0.01 Hz increments. If set to 0 Hz, the left and right channels will have the same frequency, allowing you to play pure Solfeggio frequencies.

- You can set the following fluctuations with a single tap. Since the frequency is set to approximately the center of each frequency range, please use the ±0.01 buttons for fine-tuning.
    • δ waves 2 Hz (less than 4 Hz): Brain waves that appear during deep sleep. They contribute to cell repair and strengthening of immune function.
    • θ waves 5.5 Hz (4–7 Hz): Brain waves that appear during light sleep, such as REM sleep, or during deep meditation. They contribute to memory formation when absorbing new information.
    • Schumann Resonance 7.83 Hz: The Earth’s natural frequency. Effective for stress relief. Synchronizes consciousness with the Earth.
    • Alpha waves 11 Hz (8–13 Hz): Brain waves that appear during relaxation or meditation. They indicate low stress levels and a calm, composed state of mind.
    • Beta waves 22 Hz (14–30 Hz): Brain waves that appear during wakefulness and concentration. Excessive beta wave activity can cause stress and anxiety.
    • Gamma waves 40Hz (30–80Hz): These brain waves are strongly present when multiple neural networks are active simultaneously.

- Use the gear button to save up to five named combinations, which can be restored with a single tap. To rename a combination, tap the text field.
