acoustics

Is there a Java-based ray tracing model that can be adapted for use in underwater acoustics?

I am looking for an open-source Java-based raytracing system suitable for use in modeling underwater ray-based acoustics. Such a package might be similar to the Comprehensive Acoustic System Simulation (CASS) with the Gaussian Ray Bundle (GRAB) but I would prefer an open-source, free-to-use or free-to-modify model that I can use in pres...

Drive an DAC from a stream that is clocked from another source?

Hi, My DAC is internally clocked at 48khz, I need to feed it from a stream that is also 48khz but is clocked from a different source. The two sources will drift over time and any buffering in between will inevitably overflow or underflow. Unfortunately, there is no rate control mechanism available for the source. How can this best be...

Loading the data for a Simulink Lookup Table from a file

Hello, I've built a Matlab/Simulink model that I'm using to simulate the performance of an underwater robotic vehicle that uses acoustics for various key navigation and localisation functions. Since the characteristics of the ocean change with seasonality and geolocation, I would like this data to be dynamically loaded into the model f...
