The Dream 2.2 branch is relatively stable for AAC decoding. When I get some time I want to finish the xHE-AAC decoder.
2.2 works well on OSX and can work OK on linux although I'm still not sure what the best audio driver should be.
But we have this nasty build problem on Windows 10. If anyone can help make a build and an installer that will make working Windows 10 installs easy it would be really helpful.

Hi Julian, I am sure you will find multiple volunteers, me one among many.
I have been trying without much success to buld a working dream with xHE-aac support for last one week. I have tried multiple branches, with MSVC as well as QT creator and all I get is thousands of build error thrown at me for every error I fix. You can check the last few messages to find my ordeal.
I will be happy to help write build instructions for Windows if you can fix this for good.

After recompiling all necessary dll, and lib files, I can run Dream2.2 over windows10. But I have these problems:
When I selected input device through "sound card select" drop-down menu, programe crashed. This is QtCreator IDE screen shot. If I inserted "try.. catch"expression in the suspicious "CSoundIn::Close()", the Qt exception warning disappeared, but programe crashed just the same.
Note that Dream2.1 have the same behaviour, albeit with much less frequency.
In debug mode, it behaves slightly differently: UI constantly flashing after programe starts. When I switched the soundcard input source in the drop-down selection menu, flashing stops. If I proceeded with multiple selection iterations, programe crashed. This is the screen shot.
Thanks, if debug is different from release it is usually an uninitialised variable but it would be even more useful if you could step through the programme and let me know what line it crashes on. Also can you post the output of qmake so I know for certain which libraries are being pulled in.
FYI the sound card code has changed somewhat, to try and take advantage of changes between windows 95 and windows 10. It is obviously still work-in-progress. I couldn't get the QAudio version working on Windows, it is the default now on OSX with portaudio still an option. On Windows I expect you to be still using mmsystem.

Sorry, I'm just a qtcreator newbie, so I really don't know the right procedure to do step by step debug.
Anyway, if I start debugging through 'debug'->'start debugging of "dream"' menu, I get this message:

I think I've solved the UI problem about sound card input. Except for occasional crash when xHE-AAC decoding(a feature under implementation), so far so good.
Note: the xHE-AAC decoder from FDK is useless. It simply can NOT produce any audible signal.
What did you change to fix the UI? I can give you write access to subversion if you want to create a branch and submit code, or just attach changed files here.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Your handling of superframe is correct, but unfortunately the xHE-AAC decoding support is NOT complete in FDK (or they are withholding some important details). Because even if I supply the decoder with correct data frame (frame CRC checked), it still can not parsing it properly and consistently. Note that xHE-AAC comes in many flaviours. The manifesto of FDK doesn't explicitly claim it compatible with DRM bitstream.
P.S.
OK, for the completeness of this thread and not to mislead other FDK users, I retract my claim about the incompatibility of FDK. For the record, FDK IS indeed compatible with DRM bitstream, whether normal AAC or xHE-AAC. My bad experience is due to BAD compiler compatibility: I used the VC++6.0 and it generated half-baked code ( normal AAC works but not xHE-AAC!!).
After I saw the success of kiwiSDR, I realised some thing's wrong with the way I used the FDK.Sorry for the confusion I caused to other users.

My version works on Dream2.1.x, and it needs static library "fdk-aac.lib"at link time. So, you still have to built your own fdk library one way or another due to copyright issues. On the other hande, building your fdk lib is quite easily.Just go to https://sourceforge.net/projects/drm/files/helper%20files/

You have to choose files with "fdk-aac" prefix. Only FDK library supports xHE-AAC, while FAAD does not. The source code is self-contained, ie. no need to copy extra files. If MSVC reports missing files, check your include path in your project setting.

Thats helpful. Could you run a debug build and see if we get any better information such as a line number or the kind of exception that is thrown?
In debug mode, it behaves slightly differently: UI constantly flashing after programe starts. When I switched the soundcard input source in the drop-down selection menu, flashing stops. If I proceeded with multiple selection iterations, programe crashed. This is the screen shot.

4 files need to change in my case. see the attachment. BTW, line133 in "SoundCardSelMenu.cpp" is redunant or your typo?
insert " CMutex mutexSound; " to "creceivedata.h" and change "creceivedata.cpp" according the attatchment.

I'm pretty sure the FDK decoder works. The problem is the sliding superframe which I know roughly how to handle but haven't found time to get working.
The superfame is at section 5.3 here: https://www.etsi.org/deliver/etsi_es/201900_201999/201980/04.01.02_60/es_201980v040102p.pdf

Ok, I am not a programmer and need some help here.
This is what i did.
- Installed Installed MS visual studion 2019 community edition
- In a Folder name libfaad extracted faad2_project_files.zip from https://sourceforge.net/projects/drm/files/helper%20files/
I then open the project file called "libfaad2_dll_drm.vcproj" from vsual studio 2019 and click Build => Build Solution => and get below output with missing .C and .H files
I found all these missing files here: https://sourceforge.net/projects/faac/files/faad2-src/faad2-2.7/ and copied them and re run Build => Build Solution => and get below errors
I am now not sure what I am doing wrong. Some help will be appreceated.
