Abstract: Systems and methods are provided for master media clock recovery. In various embodiments, recovering a master media clock may comprise receiving clock reference format (CRF) packets carrying timestamps (Ts). Differences of Ts between adjacent CRF packets may be calculated, and an average difference of Ts between adjacent timestamps may be calculated. A recovered frequency of a master clock may be based on the calculated average difference of Ts between adjacent timestamps. The recovered frequency may be used to regulate a timing of, for example, a kernel module and/or a media application.

Abstract: A mounting system for mounting a loudspeaker to a substrate includes a mounting assembly having an elongated screw, a support member received on and movable along the screw, and a mounting arm rotatably connected to the support member and having a resting position and a working position. A guide housing receives the mounting assembly with the screw extending longitudinally therethrough and includes a wall structure with an open front side and a cap at a top portion of the wall structure. In the resting position, the support member is positioned along the screw at least partially received within the cap and the mounting arm is substantially contained within the wall structure. In the working position, the support member is positioned along the screw to be outside of the cap and the mounting arm is spring-biased away from the screw and extends outwardly through the front side of the wall structure.

Abstract: A system and method for estimating secondary path impulse response (IR) for an active noise cancellation (ANC) system to enhance performance of the ANC system in a near-imperceptible manner is provided. An adaptive music interference canceller (AMIC) uses music signals as test signals and ANC error microphones to estimate the secondary path IR between all speakers and microphones. The system validates that the music signals have sufficient audio content to be considered an adequate test signal. Furthermore, the system employs additional signal processing to ensure that a unique IR for all speakers and microphones can be obtained using the audio test signals. New coefficients of the AMIC filter are calculated, in real time, using the music signals and can be copied into the estimated secondary path for the ANC system. A supervisor unit manages enabling and disabling the AMIC as needed for calculating and copying coefficients.

Abstract: A handsfree system and method to modify at least one microphone output based on a linearized correlation between a modified Speech Intelligibility Index (mSII) and a Mean Opinion Score (MOS). The at least one microphone output signal is compared to predetermined thresholds for the mSII that correspond to a noise condition and the microphone output signal is modified to optimize Speech Intelligibility and Sound Quality for the noise condition.
