frequencies of the two separate tones used to create the binaural-beat sound effect. As a result, its overall application is limited by its inability to independently provide both disruptive and patterning stimuli to different brain regions and separate hemispheres. Binaural beats are physiologically ineffective above about 20Hz (Oster, 1973), yet gamma frequencies in the range of 40Hz have recently been discovered to be critical to the quantum aspects of brain function, especially hemispheric coherence (Hameroff, 2010). SAM is not confined by these same limitations. Comparing the signals used for binaural beats, monaural beats, and isochronic tones with those presented for SAM, it is clear that Spatial Angle Modulation offers a wealth of possibilities that are not available with these other methods. The most significant factors in the SAM signal format for creating a shift in consciousness are (1) the differences in signal delay that occur as a sound in a natural environment reaches the ears of a listener and (2) the way these delay differences change as the signal source moves in the environment. In addition to controlling the nominal frequency of the sound source and the frequency at which the arc tremolo effect is produced, there are several other parameters that can be adjusted to control spatial aspects of the signal and its neurological effects. As well as controlling the SAM carrier frequency and tremolo frequencies, SAM also provides more degrees of

freedom in controlling arc parameters. By controlling the peak phase deviation, an equivalent sound source can follow arcs of different sizes or even extend into situations that have no physical correlate. By controlling the pair of phase constants in the SAM format, movement arcs can be assigned to different apparent angular locations in longitude and latitude. Neglecting volume as a parameter, which is common to any sound format, the basic binaural-beat format, for example, offers only two important degrees of freedom in its choice of left and right frequencies; SAM offers five degrees of freedom with its choices of carrier frequency, modulation frequency, peak phase deviation, and the angular offset provided by a pair of constants and the combination of different angular presentations. There are other naturally occurring means of entering into similar altered states, such as that of extreme relaxation, breathing techniques, and/or singing and chanting. The SAM audio support technology was designed and intended to be used in conjunction with these and other consciousness-shifting techniques (such as sitting in a darkened room), social-psychological conditioning tools (such as intra-group affirmation, affinity and/or communion), and educational curriculum (in which new cognitive, “consciousness expansion” skills are learned, i.e., breath work, visualization, etc.).
SAM is intended to be a safe and effective means of facilitating altered states in which the listener can engage in personal exploration and/or address a variety of physiological and/or psychological concerns. SAM has applications in a number of areas, including: inducement of sleep, lucid dreaming, heightened awareness during the normal waking state, focusing of attention, increasing mental and physical relaxation, enhancing intellectual performance in various mental disciplines, the enhancement of creativity, and the acquisition of “extraordinary” abilities such as nonlocal knowing, etc. Next Page 5 TMI JOURNAL 2012 In short, SAM is distinct from other audio-guidance technologies intended to facilitate shifts in consciousness in the listener in that (1) SAM works more quickly than other methods, (2) SAM technology utilizes a distinct signal format from other audio technologies, and (3) the SAM signal format is unique in its increased flexibility in breadth and arrangement of signals (specifically, its carrier frequency, modulation frequency, peak phase deviation, and the angular presentations). This allows for increased options for creating a greater number of signal “symphonies,” thereby also allowing for a wider variety of psychological-subjective and neurological effects in the listener.
