* [JMBE Download Site](https://github.com/DSheirer/jmbe/releases) Follow the instructions on this site for building the JMBE library.
* Copy the **jmbe-x.x.x.jar** file to the same folder where you run the sdrtrunk scripts to start the sdrtrunk program.
* You can use the compiled **jmbe-x.x.x.jar** file right where you compiled it, or it may make sense to copy it to a more permanent location on your computer that is always accessible for sdrtrunk.
* Start SDRTrunk normally and the program will automatically discover and use the jmbe library.
* Start the SDRTrunk application.
* Open the **View >> Preferences** menu item to open the Preferences window.
* In the **Decoder >> JMBE Audio Library** section, click the **Change...** button to specify the
location for the 'jmbe-1.0.0.jar' library is located. (or whichever version you just compiled)
* Start (or restart) any P25 decoder channels to start using the audio library.
## Troubleshooting ##
If you download, compile and copy the JMBE library jar file to the same directory as the SDRTrunk application, you should not have any issues.
SDRTrunk will generate several log entries to let you know if it discovered the jmbe library correctly and where it was looking for the library:
SDRTrunk will generate a log entry to let you know if it discovered the jmbe library correctly for each P25 channel that you have decoding:
> 16:59:28.404 INFO i.g.d.a.c.m.JmbeAudioModule - Loading JMBE library from [/home/denny/JMBE/jmbe-1.0.0.jar]
> 09:38:54.166 INFO d.p.audio.P25AudioOutput - JMBE audio conversion library successfully loaded - P25 audio will be available
> 16:59:28.415 INFO i.g.d.a.c.m.JmbeAudioModule - JMBE audio conversion library loaded: JMBE Audio Conversion Library v1.0.0
Or, when the library cannot be found, each channel will log:
P25 Phase 1 channels when started will log the following entry:
> 09:38:54.166 INFO d.p.audio.P25AudioOutput - JMBE audio conversion library NOT FOUND
> 16:59:28.415 INFO i.g.d.a.c.m.ImbeAudioModule - JMBE audio conversion library IMBE CODEC successfully loaded - P25-1 audio will be available
P25 Phase 2 channels when started will log the following entry:
> 16:59:28.415 INFO i.g.d.a.c.m.AmbeAudioModule - AMBE CODEC successfully loaded - P25-2/DMR/NXDN audio will be available
Note: Phase 2, DMR and NXDN protocols all use the same audio codec. Decoder support for DMR and NXDN may be added at a future time
