Type Binaural beats
License Proprietary

I-Doser is an application for the playback of proprietary audio content. The developer claims the separately purchasable content aims to simulate specific mental states through the use of binaural beats, and much of it is named after prohibited recreational drugs.[1] The I-Doser player has been downloaded more than a million times[2] and is based on the audio technology of a GPL-licensed binaural beat generator, SBaGen.[3] The player can be downloaded for free, but the audio content has to be purchased.


I-Doser tracks are usually 30–40 minutes long and administered with a program called I-Doser V5. The file format containing the encoded sounds ends in .drg which only the I-Doser program can run. Most doses are priced in the US $1.99-$3.99. There are a small number of premium experimental doses costing hundreds of dollars. Some are marketed as intended for relaxation, others to simulate substances and others for mind/mental improvement, like the title Brain+, or 3 called Alpha, Beta, and Theta to target those parts of the brainwaves. There are also mobile applications available for iOS and Android with an extensive in-app store for additional doses. MP3 and CD "packs" can also be purchased, that are simply the doses ported to the format enhanced with ambient sound and music.

The I-Doser .drg files are a derivation of the open source SBaGen file format. The marketing hype behind I-Doser that spread like wildfire over the internet has helped drive its sales.

Evaluation of claims[edit]

Research into the neurological technology behind I-Doser is sparse. Peer-reviewed studies exist suggesting that some specific binaural beat mixes can affect aspects of mental performance and mood,[4][5] act as analgesic supplements[6] or affect perceptions,[7] but there have been no formal studies of any effects of mixes particular to I-Doser. Researchers from Oregon Health and Science University interviewed about I-Doser have expressed skepticism over its scientific basis, citing a four person controlled study of binaural beats that demonstrated no evidence of brainwave entrainment.[8] Other universities have also stated skepticism.[9]
