Abstract: An apparatus provides personalized binaural audio rendering of an input signal. The apparatus has a left ear transducer configured to generate a left ear audio signal and a right ear transducer configured to generate a right ear audio signal. Moreover, the apparatus has processing circuitry configured to determine, based on a current target direction of the input signal, an adjusted current target direction using a personalized adjustment function that describes a functional relationship between a plurality of reference target directions of a reference sound signal and a plurality of perceived reference target directions of the reference sound signal as perceived by a user. The processing circuitry is further configured to implement a target direction renderer configured to generate based on the input signal and the adjusted target direction a first driving signal for driving the left ear transducer and a second driving signal for driving the right ear transducer.

Abstract: A suppressor includes baffles with geometry and spacing minimizing sound level in the human hearing range, and overlapping tapers on consecutive elements replacing welds. The geometry includes conical baffles with approach angles between 153.7 and 163.7 degrees and at least one inch separation. The suppressor is assembled by compressing the elements between threaded end caps, thus expending the overlapping tapers against the interior of a suppressor tube to center and align the baffles. The suppressor may be attached to a rifle using a quick disconnect mount which includes an adapter fixed to the rifle barrel and having an “L” shaped slot with a first leg parallel to the barrel and a second leg turned greater than 90 degrees towards the front of the adapter. A post in the suppressor engaged the slot and a spring biases the suppressor forward and holds the post at the end of the turned leg.
