BrainWave: Altered States ™11.0.1 - App Store

Combine Mind Altering Binaural Sequences with Soothing Nature Sounds, Ambient Music, your own iTunes Music (with the built-in iTunes playlist creator), or play alongside apps like Spotify and Audio Book Readers. * Powerful Binaural Programs for Lucid Dreaming, Mindful Meditation, Dreamy Sleep, Astral Projection, Zen Meditation and much more! * Universal app with built-in UIs for iPhone/iPad * Different states of mind are associated with specific brainwave frequencies that would inaudible if played directly, but can be induced by playing two different audible binaural tones into each ear, which, after being processed by the brain, are perceived as an inaudible low frequency beat matching the target brainwave frequency. As you listen your brainwaves fall into step with this inaudible beat, and after several minutes synchronize with the target frequency.

Uses the most advanced multi-stage binaural sequences available, combined with the flexibility to choose from a range of relaxing ambient backgrounds, other audio apps, or your own iTunes Music, allowing your mind you to relax and synchronize with your desired state. It achieves this using our unique process called Progressive Brainwave Entrainment.

*** Progressive Brainwave Entrainment ***

Progressive Brainwave Entrainment algorithms use layers of frequencies and carrier signals assembled in precise sequences to create profoundly unique experiences. Each program gently brings your brainwave frequencies to your desired state using a more natural frequency progression.

*** Advanced Features ***

- 22 Brainwave programs each specially designed for a different situation and desired mental state.

- 24 ambient background sounds to choose from.

- Clear Lock Screen after Stop: This option is enabled by default and clears the app from the device lock screen after the Stop button is tapped. This option is only relevant when the Background Mode is set to "Ambience Only", as this is the only mode for which iOS places the app on the lock screen. This feature was added to help prevent car audio systems from resuming the app upon connection. Most car audio system automatically send a Bluetooth play command upon connection, which causes any audio/video app present on the lock screen to begin playing.

- Auto-Resume after Interrupt: This setting causes the app to resume playing if it was interrupted by a short call.

- Gray, Green, and Velvet Noise

* How it Works *

During the entrainment process, two different carrier tones are played into the left and right ears. The frequency difference between these tones matches the brainwave frequency of the target state of mind. The listener will hear these carrier tones as an audible tone, however, when processing these two different tones the human brain will perceive the small frequency difference between the tones as an inaudible periodic beat. When exposed to this beat the listener's brainwaves will begin to synchronize with the beat frequency. What allows the human brain to perceive this beat is our directional hearing system, located in the brain stem. The brain's directional hearing system calculates frequency shifts between sound entering the left and right ear to quickly locate the direction of a sound, but when that difference is rhythmic, as with binaural tones, the brain synchronizes with the pattern. This process is more effective in the presence of background noise or ambience, which allows humans to hear and locate even subtle sounds, like an animal moving nearby in a forest that is filled with noise.

As an example, the human ear can't directly perceive the 1 - 2 Hz Delta-wave frequencies associated with deep sleep because it is well below the human hearing range, but if you wear headphones or earbuds with one side playing a 135 Hz tone and the other playing a 136 Hz tone your brain will perceive the 1 Hz difference between those frequencies as a periodic beat, in this case matching a low delta wave frequency associated with sleep. As you listen, your own brainwaves will begin to match that frequency.

Warning: Do not use this app while driving or operating machinery.

The 10.0 update also includes several new settings as well as new binaural programs and background audio. The new options are located in the app's General Settings, which is accessed by tapping the wrench-button on the main screen:
* Reduce Other App Volume - Option to enable audio ducking which instructs iOS to reduce the volume of other apps by 50% while this app is playing. iOS does not allow the volume reduction to be customized.
* Wave Amplitude Boost - Option to boost the amplitude of the binaural carrier waves by a fixed amount to provide an additional increase in volume. This option is provided as an on/off toggle setting.
* Carrier Signal (2 Options)- Option to switch between the default low-frequency binaural carrier wave and a medium carrier wave of ~250 Hz. This will not alter the frequency of the binaural tones. Example: A 1 Hz tone on a low-frequency carrier uses 121 Hz Left and 120 Hz Right, but with a Mid-carrier uses 221 Hz Left and 220 Hz Right.
* Option to export time spent listening to Relaxation and Meditation programs to the Apple Health App as Mindful Minutes.

* Brainwave Frequencies *
Different states of mind will display a dominant frequency, but all brainwaves are present in a mix at all times.

Gamma waves (30-44 Hz):
Associated with high-level information processing, multi-tasking, excitement, and high energy.

High-Beta waves (18-29 Hz):
Associated with mental activities such as math, planning, and design.

Mid-Beta waves (15-17 Hz):
Increased problem-solving ability, focus, and alertness.

Low-Beta waves (12-14 Hz):
Relaxed, yet still mentally sharp

High-Alpha waves (10-11 Hz):
Relaxed, centered, tranquil

Low-Alpha waves (8-9 Hz):
Relaxed, almost meditative but still aware

Theta waves (4-7 Hz):
Associated with deep meditation, creativity, intuition, and dream-like states. Theta waves also occur during REM sleep and the early stages of deep, slow-wave sleep.

Delta waves (.5-3 Hz):
Deep, slow-wave sleep. Slow-wave sleep allows the brain to recover from daily activities. It is important for hormonal regulation, growth, memory retention, and physical renewal. 8.1.3 10/04/2019 * Headphones or Earbuds are Required for Binaural Tones to be Effective

* Added the ability to play and pause audio using Remote Controls *only* when using Brainwaves with the included Ambience. In modes that allow other audio apps or iTunes Music to be playing these controls will only affect iTunes or the other app. This is because in modes where our app allows other audio to play that other app becomes the "Now Playing" app--and there can be only one "Now Playing" app on iOS.
* Added a 5th Ambience Mode: Ambience + Other App. Remote Controls will not control our app in this mode because we allow another app to be playing.

* How Brainwave Entrainment Works *
During the entrainment process, two different carrier tones are played into the left and right ears. The frequency difference between these tones matches the brainwave frequency of the target state of mind. The listener will hear these carrier tones as an audible tone, however, when processing these two different tones the human brain will perceive the small frequency difference between the tones as an inaudible periodic beat. When exposed to this beat the listener's brainwaves will begin to synchronize with the beat frequency. What allows the human brain to perceive this beat is our directional hearing system, located in the brain stem. The brain's directional hearing system calculates frequency shifts between sound entering the left and right ear to quickly locate the direction of a sound, but when that difference is rhythmic, as with binaural tones, the brain synchronizes with the pattern. This process is more effective in the presence of background noise or ambient sounds, which allows humans to hear and locate even subtle sounds, like an animal moving nearby in a forest that is filled with noise. It is also what allows humans to perceive the beat frequency produced by tuning forks.

As an example, the human ear can't directly perceive the .5 - 2 Hz Delta-wave frequencies associated with deep sleep because it is well below the human hearing range, but if you wear headphones or earbuds with one side playing a 135 Hz tone and the other playing a 136 Hz tone your brain will perceive the 1 Hz difference between those frequencies as a periodic beat, in this case matching a low delta wave frequency associated with sleep. As you listen, your own brainwaves will begin to match that frequency.

* Brainwave Frequencies *
Different states of mind will display a dominant frequency, but all brainwaves are present in a mix at all times.

Gamma waves (30-44 Hz):
Associated with high-level information processing, multi-tasking, excitement, and high energy.

High-Beta waves (18-29 Hz):
Associated with mental activities such as math, planning, and design.

Mid-Beta waves (15-17 Hz):
Increased problem-solving ability, focus, and alertness.

Low-Beta waves (12-14 Hz):
Relaxed, yet still mentally sharp

High-Alpha waves (10-11 Hz):
Relaxed, centered, tranquil

Low-Alpha waves (8-9 Hz):
Relaxed, almost meditative but still aware

Theta waves (4-7 Hz):
Associated with deep meditation, creativity, intuition, and dream-like states. Theta waves also occur during REM sleep and the early stages of deep, slow-wave sleep.

Delta waves (.5-3 Hz):
Deep, slow-wave sleep. Slow-wave sleep allows the brain to recover from daily activities. It is important for hormonal regulation, growth, memory retention, and physical renewal. 8.1.1 09/06/2019 * This update is required for iOS 13 compatibility.
