Pre-release

@DSheirer DSheirer released this Sep 23, 2018 · 6 commits to master since this release

Assets 3

NOTE: this is an 'alpha' release which means it is NOT feature complete and it may contain bugs, but is provided as an early preview of significant enhancements to the software.

This preview (alpha) release contains a complete redesign of the channelizer sub-system and a new reusable buffer concept. These two enhancements dramatically reduce memory usage and reduce/stabilize overall CPU utilization.

This release should perform significantly better on computers with reduced CPU and memory resources.

WINDOWS: double-click the file, or open a terminal to the download location and type: java -jar sdr-trunk-all-0.4.0-alpha.5.jar

LINUX: open a terminal window to the download location and type: java -jar sdr-trunk-all-0.4.0-alpha.5.jar

Note: place a copy of the JMBE library in the same directory as the sdr-trunk-all-0.4.0-alpha.5.jar to enable P25 audio decoding.

Requirements:

Java Version 8 (or newer): http://www.oracle.com/technetwork/java/javase/overview/index.html

Optional Requirements

JMBE version 0.3.3 is used for decoding APCO25 digital audio. Instructions for compiling this library are located at: https://github.com/DSheirer/sdrtrunk/wiki/JMBE
