AMBE tone frames are not being correctly identified so that tone audio can be generated.

Hello,

I was having some issues compiling JMBE on various linux systems including a Raspberry Pi running Ubuntu 18.04.2 LTS (64-bit/aarch64), using Open JDK 11.0.2.

The dreaded:

* What went wrong:
Could not determine java version from '11.0.4'.

After doing some digging, I found out Gradle v4.x (what JMBE's wrapper is built with) doesn't support Open JDK 11.x. So I simply modified the build.gradle as follows. (Not pretty)

5c5,6
< sourceCompatibility = 1.8
---
> //sourceCompatibility = 1.8
> sourceCompatibility = '11'
69,70c70,71
< task wrapper(type: Wrapper) {
<     gradleVersion = '4.3.1'
---
> task wrapper1(type: Wrapper) {
>     gradleVersion = '5.0'

And then modified jmbe-0.3.3b/gradle/wrapper/gradle-wrapper.properties.

5c5
< distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-bin.zip
---
> distributionUrl=https\://services.gradle.org/distributions/gradle-5.0-bin.zip

These changes allowed me to build JMBE without any issues on Ubuntu 18.04.2 LTS Server (64-bit/aarch64) running on a Raspberry Pi 3b+, as well as Ubuntu 18.04.2 LTS on x86_64.

Raspberry Pi: Linux RPI 4.15.0-1041-raspi2 #44-Ubuntu SMP PREEMPT Wed Jul 3 15:45:20 UTC 2019 aarch64 aarch64 aarch64 GNU/Linux

Laptop: Linux Laptop 4.15.0-46-generic #49-Ubuntu SMP Wed Feb 6 09:33:07 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

I hope this is helpful to someone, and thanks for SDRtrunk!

Reference the support thread here:
https://groups.google.com/forum/#!topic/sdrtrunk/DX_lMZUFJxI

There's a possibility that the invalid AMBE frames are incorrectly tagged as Tone frames and the library attempts to generate tone audio for the frame.

I want to use this library in my own porject but when ı run gradlew.bat api command, I get "Task 'api' not found in root project 'jmbe' " eror.

When logging the library name, it's reporting 1.0.3 versus the current version.

can you make it dump all data to hard drive to play back later.
something like "IdTimeDate.p25 preserving all the data transmitted.

Create an application that is fully self-contained that downloads the JMBE source code and creates the JMBE library.

Tried compiling on both Ununtu 18.10 and Windows 10 with same error on both

Clicking on links to jmbe_builder.* files on "Version 0.3.2 Update 1" release page (https://github.com/DSheirer/jmbe/releases) results in "The request signature we calculated does not match the signature you provided. Check your key and signing method." error message.

Audio stops soon after monitoring is started with stuttering and buffer issues. All other functions appear to be working normally. The terminal capture reveals:

13:29:03.446 ERROR i.g.d.a.p.AudioOutput - Error while processing audio buffers [87MB/640MB 13%] java.lang.NullPointerException: Cannot invoke "javax.sound.sampled.SourceDataLine.isRunning()" because "this.mOutput" is null at io.github.dsheirer.audio.playback.AudioOutput.checkStop(AudioOutput.java:653) at io.github.dsheirer.audio.playback.AudioOutput.processAudio(AudioOutput.java:509) at io.github.dsheirer.audio.playback.AudioOutput$AudioSegmentProcessor.run(AudioOutput.java:743) at java.base/java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) at java.base/java.util.concurrent.FutureTask.runAndReset(Unknown Source) at java.base/java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(Unknown Source) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.base/java.lang.Thread.run(Unknown Source)

So when I pull up the Users Preference dialog and Output/Tones and just switch between Audio Output Device selections the audio will resume and then once the error repeats, switch the Source back to the original, the audio starts again. This repeats indefinitely.

When running gradlew.bat build I see the following message but when I look in the folder I cant find the jar file (no lib or build directory)

Hi, I am getting this error while running SDR Trunk. I am also getting this error: JMBE audio conversion library NOT FOUND. What do these error mean and how can I repair these errors? I put the jmbe file in the same folder of sdr trunk.

The problem is that build directory doesn't exist and no jar file was actually created.
I can compile it myself but it should be noted the script is claiming to have completed successfully when from what I can tell it created no .jar in the process.

Occasionally there is an audio frame that is decoded incorrectly as a Tone frame and it's producing audio glitching or artifacts. This situation can be detected as a Tone frame that's bounded by an audio frame on either side.

Update the tone generator to only generate tone audio when there is a tone sequence, meaning that the previous frame was a tone and the current frame is a tone.

On the first tone frame, do an audio frame repeat. Since this will cause the initial tone frame to be generated as an audio frame, perhaps we can detect the start and then double the length of the generated tone when the second frame arrives.

Encountered an NPE while developing DMR decoder.

Hi!

Is there a simple way to bypass the error correction routine and be able to supply a 88 bit imbe input Vs the 144 bit.

Is there a simple code mod to bypass it?

Thanks heaps.

Provide an application user interface that can download, compile and copy the JMBE library to a designated location to make it easier on the user to create the JMBE library.

I'm getting no audio when I am listening to P25-2 channels.

After some digging, I found this on the JMBE Wiki:

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

But I never see any of that when I run the sdr-trunk file. I see the following:
i.g.d.a.c.m.ImbeAudioModule - JMBE audio conversion library IMBE CODEC successfully loaded - P25-1 audio will be available [46MB/72MB 64%]

That is the only mention of P25. I double-checked with Command + F as well.

Please excuse my lack of knowledge/proper nomenclature. I am happy to provide more details, just let me know.

The main() method in the IMBEFrame class contains code that is deprecated in JDK 9. Remove the main class.

The AMBEFrame object is created twice, and hence fully processed twice. Rather than creating the AMBEFrame object and passing its reference down the line.

The get audio method used here takes frame data and creates a new AMBEFrame. However an instance of AMBEFrame is created just before this and can be passed it getAudio instead.

Another getAudio method is available that already takes an AMBEFrame object. This way the frame is not decoded, error corrected, and processed twice.
