Binaural Beats and Monaural Beats with Python

AccelBrainBeat is a Python library for creating the binaural beats or monaural beats. You can play these beats and generate wav files. The frequencys can be optionally selected.

Description

This Python script enables you to handle your mind state by a kind of "Brain-Wave Controller" which is generally known as Biaural beat or Monauarl beats in a simplified method.

Dependencies

Use-case on console

You can study or work while listening to the Binaural or Monauarl beats. Before starting your job, run a batch program on console.

Create and play "Binaural Beat" on console

Run the batch program: play_binaural_beat.py.

python play_binaural_beat.py -l 400 -r 430 -t 60 -v 0.01
usage: play_binaural_beat.py [-h] [-l LEFT] [-r RIGHT] [-t TIME] [-v VOLUME]

Create and play the Binaural Beat.

optional arguments:
  -h, --help            show this help message and exit
  -l LEFT, --left LEFT  Left frequencys (Hz).
  -r RIGHT, --right RIGHT
                        Right frequencys (Hz).
  -t TIME, --time TIME  Play time. This is per seconds.
  -v VOLUME, --volume VOLUME
                        Sound volume.

Create and play "Monaural Beat" on console

Run the batch program: play_monaural_beat.py.

python play_monaural_beat_beat.py -l 400 -r 430 -t 60 -v 0.01
usage: play_monaural_beat.py [-h] [-l LEFT] [-r RIGHT] [-t TIME] [-v VOLUME]

Create and play the Monaural Beat.

optional arguments:
  -h, --help            show this help message and exit
  -l LEFT, --left LEFT  Left frequencys (Hz).
  -r RIGHT, --right RIGHT
                        Right frequencys (Hz).
  -t TIME, --time TIME  Play time. This is per seconds.
  -v VOLUME, --volume VOLUME
                        Sound volume.

Use-case for coding

You can use this library as a module by executing an import statement in your Python source file.

Create and play "Binaural Beat"

For example, if 400 Hz was played in left ear and 430 Hz in the right, then the binaural beats would have a frequency of 30 Hz.

Import Python and Cython modules.

from AccelBrainBeat.brainbeat.binaural_beat import BinauralBeat

Instantiate objects and call the method.

brain_beat = BinauralBeat()

brain_beat.play_beat(
    frequencys=(400, 430),
    play_time=10,
    volume=0.01
)
  • The type of frequencys is tuple. This is a pair of both frequencys.
  • play_time is playing times(per seconds).
  • volume is the sound volume. It depends on your environment.

Create and play "Monaural Beat"

The interface of monaural beats is same as the binaural beats. MonoauralBeat is functionally equivalent to BinauralBeat.

from AccelBrainBeat.brainbeat.monaural_beat import MonauralBeat

brain_beat = MonauralBeat()

brain_beat.play_beat(
    frequencys=(400, 430),
    play_time=10,
    volume=0.01
)

Create wav file of "Binaural Beat"

Call the method.

from AccelBrainBeat.brainbeat.binaural_beat import BinauralBeat

brain_beat = BinauralBeat() # for binaural beats.
brain_beat.save_beat(
    output_file_name="save_binaural_beat.wav",
    frequencys=(400, 430),
    play_time=10,
    volume=0.01
)
  • output_file_name is wav file name or path.

Create wav file of "Monaural Beat"

The interface of monaural beats is also same as the binaural beats.

from AccelBrainBeat.brainbeat.monaural_beat import MonauralBeat

brain_beat = MonauralBeat() # for monaural beats.
brain_beat.save_beat(
    output_file_name="save_monaural_beat.wav",
    frequencys=(400, 430),
    play_time=10,
    volume=0.01
)

Description

The function of this library is inducing you to be extreme immersive mind state on the path to peak performance. You can handle your mind state by using this library which is able to control your brain waves by the binaural beats and the monaural beats.

Concept of Binaural beats and Monauarl beats

According to a popular theory, brain waves such as Delta, Theta, Alpha, Beta, and Gamma rhythms tend to be correlated with mind states. The delta waves(1-3 Hz) are regarded as the slowest brain waves that are typically produced during the deep stages of sleep. The theta waves(4-7 Hz) are offen induced by the meditative state or focusing the mind. The alpha waves(8-12 Hz) are associate with relaxed state. The beta waves(13-29 Hz) are normal waking consciousness. The Gamma waves(30-100 Hz) are the fastest of the brain waves and associated with peak concentration and the brain's optimal frequency for cognitive functioning.

By a theory of the binaural beats, signals of two different frequencies from headphone or earphone are presented separately, one to each ear, your brain detects the phase variation between the frequencies and tries to reconcile that difference. The effect on the brain waves depends on the difference in frequencies of each tone. For example, if 400 Hz was played in one ear and 430 in the other, then the binaural beats would have a frequency of 30 Hz.

The monaural beats are similar to the binaural beats. But they vary in distinct ways. The binaural beats seem to be "created" or perceived by cortical areas combining the two different frequencies. On the other hand, the monaural beats are due to direct stimulation of the basilar membrane. This makes it possible to hear the beats.

Please choose either binaural beets or monaural beats. If you set up 5 Hz, your brain waves and the frequency can be tuned and then you are able to be the meditative state or focusing the mind. Or what you choose to be relaxed state is the alpha waves(8-12 Hz).
