cocoaPath Description

Free tool that implements an HF Channel Simulator cocoaPath is a free and easy to use Mac OS X Universal Binary Cocoa based application that implements an HF Channel Simulator. cocoaPath uses the ionospheric propagation model that is based on the paper "Experimental Confirmation of an HF Channel Model" by Clark Watterson, John Juroshek and William Bensema which was published in the December 1970 issue of the IEEE Transactions on Communication Technology. What's New in This Release: · Signal-to-Noise Ratio display now reads to 2 decimal places. · Output attenuator range is changed from 24 dB to 48 dB. · The sampling rate of 16000 samples/second was not working before, the internal FIFO has been increased to handle that sampling rate. · The input section selection (Generator, File, Device) was not saved to the plist. This caused cocoaPath to default to the Generator selection each time it is launched. The input selection should now be saved to the plist. Recording duration is now reported in the output section, and there is now an auto record setting: · When Auto Record is selected and input data is started, the Auto-recording window appears and there is a field to automatically stop the input stream after a set amount of time. In addition, if you have selected either a Generator or a sound file as input, and leave the output Playthrough unselected, the recording can be done at up to 8 times the real-time rate. (The actual speed up depends on the speed of the processor.)
