Are all binaural beats the same?

[Eren Eeager]

many different frequencies and "brain waves"? Are they all the same? Is there a bettrr frequency for meditation for example? 

[Moksha]

Binaural beats in the delta (1 to 4 Hz) range have been associated with deep sleep and relaxation.

Binaural beats in the theta (4 to 8 Hz) range are linked to REM sleep, reduced anxiety, relaxation, as well as meditative and creative states.

Binaural beats in the alpha frequencies (8 to 13 Hz) are thought to encourage relaxation, promote positivity, and decrease anxiety.

Binaural beats in the lower beta frequencies (14 to 30 Hz) have been linked to increased concentration and alertness, problem solving, and improved memory.

If you want to know that answer you'll have to test every audio in existence.

Think about your question before you ask it.
