Abstract: A method and apparatus providing improved audio prioritization is provided. A public safety (PS) application programming interface (API) for an open source operating system provides a public safety extension to an audio management platform by providing configurable and updatable audio priority operation based on call type, call mode, and/or call characteristics.

Abstract: A device and method for lower latency digital audio sample playback is provided. The device comprises: a hardware digital signal processor (DSP); higher and lower latency audio paths to the DSP; a kernel driver; a kernel random-access memory (RAM) including kernel RAM buffers accessible by the kernel driver; and a controller. The controller: prior to digital audio samples being used by an application, pre-loads, using the kernel driver, the samples at the kernel RAM buffers; responsive to a trigger in the application to play a given digital audio sample, determines, using a sample identifier of the given sample, whether the given sample is pre-loaded at the kernel RAM buffers; when the sample is pre-loaded, plays, using the DSP, the given sample via the lower latency path; and when the given digital audio sample is not pre-loaded, plays, using the DSP, the given sample via the higher latency path.

Abstract: During operation, a push-to-talk (PTT) button will have a touch sensor incorporated on its surface. When the touch sensor detects a touch from a user, the apparatus will exit a low-power state and a display on the apparatus will provide PTT information.

Abstract: A mobile subscriber unit (102) transmits a signal including vocoder voices frames to a base unit (104) within a communication system (100). The base unit (104) repeats the signal including error information from the voice frames to one or more final recipient unit(s). The originating subscriber unit (102) listens to these error mitigated repeated frames and compares the received signal having error information to voice frame conditions, such as calculated, delayed and muted signal patterns. Based on the comparison, the subscriber unit (102) adjusts its power accordingly.
