New decoder for Tetra and diferents modes

[OldRabbit]

Issue solved !

I was running my RTL stick on an USB hub - and it worked with SDR# - but not with OpenEar. As soon as I plugged it directly into the laptop, I have a live waterfall and sound - - but:

Decoding WFM transmission (radio broadcast) - sound is very deep and sounds like when you slow down a recording. Odd...

Sample rate issue ?

 

[OldRabbit]

have an issue I can reproduce: When using ADS-B decoding - application crashes if I move gain above about 50% on the slider.

Distorted audio reported above gone after a reboot

No such issue on POCSAG.

in next releases i try to support more sample-rates

I think it would be really helpful to support 96k sampling rate for the next release, and therefore support decoding from raw DSD+ samples.
The addition the audio recording function is another helpful addition in v1.7.0.
I too am struggling with consistent audio output/decoding of digital signals (DMR, NXDN): both are very choppy.

It's fairly easy to resample wav files with most audio editors.

Just installed OpenEar 1.7 yesterday - and have a couple of issues.
1. Running on a Surface Pro - with a high resolution screen - user interface is seriously distorted. I managed to fix it mostly with a compatibility setting. I am running at 200% enlargement - required to read anything on this screen.
2. No sound so far - but then having VBCable installed -and having fiddled around a lot with all the confusing Windows 10 sound settings - that may be my fault. SDR# outputs sound to the speakers no problem though.

Also had issues making my cheap RTL-SDR dongle work properly - piping from SDR# and using AirSpy at least gave me visible signals in OpenEar - but so far no decoded sound.

POCSAG did decode text - so input should be OK.

I am very excited about this application - appears so much easier to use and more promising than DSD+ Fastlane - which I really struggle with.

high resolution issue: yes there is some bad placement and some coding need to solve this (try to do in free time )

No sound so far: in v1.6.0 software uses default output device as voice output then user dose not have chance to change the output but it was good for first click to sound, but on v1.7.0 user can change the output path, and default is not windows default and it is first indexed on windows settings and user must set the desired output to get voice, but for easier procedure maybe it is better that i set windows default at first selected output option on software (on next release)

Also had issues making my cheap RTL-SDR dongle work properly - piping from SDR# and using AirSpy at least gave me visible signals in OpenEar - but so far no decoded sound. i can't understand the issue, sorry, please describe more

POCSAG did decode text - so input should be OK. :
i tested POCSAG on v1.7.0 but maybe needs more test! do you have this issue on v 1.6.0?

very nice programm. like a swiss knive..
everything working fine on my Win7 32bit. But: No sound. Decoding of ADSB working fine.
Why no sound?
hopefully there will come support for Airspy mini...

thanks for your attention
about output sound, it is about same path for output settings of software and windows sound settings
in version 1.7.0 user can change output sound path (device) and user must check that what is the selected sound device on windows and then on software find that from list and select for output.
this note is more complicated when user uses input audio as input device then user must take attention to prevent from mixing of output decoded sound with input audio! all can be done by correct input and output settings

about multi hardware support, it is on plan but no time specified

yes good idea, this feature was developed but under more tests ( in 1.7.0 version user can play with external player and set input, to audio input on software, but on version 1.7.x user can load directly the demodulated audio records for input)

"I too am struggling with consistent audio output/decoding of digital signals (DMR, NXDN): both are very choppy."
there is two notes:
for nxdn (specially 48 with ~6khz bw) because of narrow BW the correct selection of signal is hard task, user try to zoom and i found the issue on zoomed click! i try to solve soon issue on zoomed click

also for audio input mode user must care that prevent for mixing of decoded output voice with input audio, it is possible with correct selection of input and output

All missing sound problems appear to have gone - as soon as I plugged the RTL dongle directly into the laptop. The USB hub - for some reason - caused issues with OpenEar - but not SDR#.

Something else may have changed- but the direct connection to the dongle appear to be what was needed.

Any chance to see DMR text decoded ?

i did not check connection rtl-usb with usb-hub, but i try to use it with usb-hub and see issue
about DMR text if your meant about text message decoding, maybe after some interested protocols, i try to it
but if your meant about some text output about network and call info like source, target,... yes also it is on plan

 

[OldRabbit]

I was thinking of DMR Text messages - and whatever other data transmission format there may exist between DMR radios.

Since a couple of week GitHub page has been removed.
Maybe the project has been discontinued ?

Hello
this GitHub page removed because of forces from DMCA (!) GitHub with some challenge in Tetra decoder!
then i removed page until i find solution for this issue
about openear, it will continue in next year with updates
but user can send empty email to openear.notifier@gmail.com to receiving latest news and updates

 

[ronenp]

Maybe you will publish somewhere the software without the tetra section after all it decoded also DMR and Other beside tetra its pitty to cancell all just because problems in the tetra

Hello @moneriom

I've downloaded your software a few time before it was deleted, i read a post regarding the DMR BP feature, and i tried the last downloaded version, sad to realise i can't find the BP section, my version was on X86, size 42 MB ;
which was the last version ? can it be downloaded somewhere ? i'd be glad to test it hope to have a new version, even if it doesn't include TETRA ... thanks for your work and good luck for your next improvement .

 

[Kazzaw]

Hello @moneriom

the DMR BP feature

IIRC this was an extremely limited paid release

 

[FMFR]

Ok i didn't understand that thank you .

 

[tango20k]

Absolutely the best DMR decoder in voice quality , waiting to see further improvements and updates in the future.

thank you for your great work Moneriom.

 

[gtab]

it's sad that software is deleted from github...
i'm starting my sdr adventure due to boredom at "covid lockdown" and this software is easy to use...
can anyone reupload any of the software version from downloads? Google drive or anything else will be great
