# Frequency Generator — Frequently Asked Questions

## What is FrequencyGenerator.com?

FrequencyGenerator.com is a free online tone generator that plays pure healing frequencies directly in your web browser, with no download or app required. You can generate Solfeggio and chakra frequencies as clean sine tones, layer them with white, pink, or brown noise, binaural beats, and a deep subharmonic tone, and bake your custom mix into a Sleep Mix that keeps playing with your phone's screen locked.

## How do I start using the frequency generator?

To begin, click the 'Start Generator' button in the center of FrequencyGenerator.com. It starts with a 174 Hz tone and brown noise by default. From there you can select any frequency, add background noise, binaural beats, or a subharmonic layer, and adjust each layer's volume independently. Press 'Stop' to end playback at any time.

## What frequencies can I generate on FrequencyGenerator.com?

FrequencyGenerator.com offers several frequency sets: Most Popular tones (432 Hz, 528 Hz, and 288 Hz), the nine Solfeggio frequencies (174, 285, 396, 417, 528, 639, 741, 852, and 963 Hz), seven Chakra Healing frequencies (256 Hz Root up to 480 Hz Crown), and both a standard and a lower 432 Hz musical scale. Each set is color-coded and clearly labeled.

## What types of background noise are available?

FrequencyGenerator.com offers three types of background noise: White noise, Pink noise, and Brown noise. You can mix these noises with any frequency to customize your healing experience. White noise covers the full frequency spectrum, pink noise is balanced across frequencies, and brown noise is deeper and low-frequency focused.

## What are binaural beats and how do I use them?

Binaural beats on FrequencyGenerator.com play two slightly different tones in your left and right ears, creating a rhythmic beat your brain perceives. You can choose Delta (2 Hz), Theta (6 Hz), or Alpha (10 Hz), and the carrier tone automatically tunes to your selected frequency. Binaural beats require headphones, because each ear needs to hear its own separate tone.

## What is the subharmonic layer?

The subharmonic layer adds a deep, low-frequency tone derived from your chosen frequency. FrequencyGenerator.com halves your core frequency until it lands in the 22–44 Hz range, so it stays in tune as you change frequencies and adds a grounding, felt-in-the-body depth. A core frequency must be playing to enable the subharmonic.

## Can I combine multiple sounds at the same time?

Yes. FrequencyGenerator.com lets you layer one core frequency together with background noise, binaural beats, and a subharmonic tone, all playing at once and each with its own independent volume. You play a single core frequency at a time, but it can be freely mixed with the other layers to build your own soundscape.

## How do I control the volume of each layer?

Each layer on FrequencyGenerator.com — Frequency, Noise, Binaural Beats, and Subharmonic — has its own volume slider measured in dBFS (decibels relative to full scale). You adjust them independently, so you can place a soft tone under stronger noise, or set any balance that feels right to you.

## What is Sleep Mode and how does 'Bake for Sleep' work?

Sleep Mode lets your mix play for hours with your phone locked. After building a mix, tap 'Bake for Sleep' and FrequencyGenerator.com optimizes it for long background playback, so your device uses less battery and the mix can keep playing in the background with the screen locked. Your mix name and playback controls appear on the lock screen. Tap 'Edit mix' whenever you want to change the sounds.

## Does FrequencyGenerator.com work on mobile with the screen locked?

Yes. FrequencyGenerator.com works in any modern mobile browser, and its Sleep Mode is built for phones. Once you bake a mix and press play, it continues playing with the screen locked and appears on your lock screen, so you can listen through the night for sleep or long meditation sessions.

## Is FrequencyGenerator.com free, and do I need to install anything?

FrequencyGenerator.com is completely free and runs entirely in your web browser. There is no app to download, no account to create, and no sign-up. It works on both desktop and mobile devices.

## What are the Solfeggio frequencies?

The Solfeggio frequencies are a set of nine tones — 174, 285, 396, 417, 528, 639, 741, 852, and 963 Hz — traditionally associated with different aspects of meditation, relaxation, and spiritual practice. FrequencyGenerator.com includes all nine, playable as pure sine tones you can mix with noise and binaural beats.

## Which chakra healing frequencies does the generator include?

FrequencyGenerator.com includes seven chakra frequencies: 256 Hz (Root), 288 Hz (Sacral), 320 Hz (Solar Plexus), 341.3 Hz (Heart), 384 Hz (Throat), 448 Hz (Third Eye), and 480 Hz (Crown). Each button is labeled with its associated chakra so you can navigate them easily.

## How should I choose a frequency for sleep or meditation?

A good starting point on FrequencyGenerator.com is the 'Most Popular' section — 432 Hz or 528 Hz — combined with brown noise at a low volume. For sleep, many people pair a low frequency such as 174 Hz with brown noise and Delta binaural beats, then bake it into a Sleep Mix. Experiment with the layers to find the combination that feels best for you.
