rtltcpaccess is a drop-in replacement for RTL283XACCESS.dll that connects to an rtl_tcp server and streams the samples from there. Its main purpose is to allow DAB reception on GNU/Linux and OS X through running the Windows software in Wine, but it works on Windows as well.
The installation script (dab_install.sh) fetches the DAB software as well as a pre-built version of the library which is also available from here:
To get the installation script, run:
wget https://raw.github.com/steve-m/rtltcpaccess/master/dab_install.sh chmod +x dab_install.sh ./dab_install.sh
If you want to build the library yourself, get MinGW and run 'make'.
Just run rtl_tcp (which comes with librtlsdr). Since the default auto-gain setting doesn't always result in the best SNR, you might want to play with the gain option [-g]. When rtl_tcp is running, start the DAB application.
By default, rtltcpaccess tries to connect to localhost:1234, you can change this by creating a key in the Wine registry:
Those are the names of the registry keys:
[HKEY_CURRENT_USER\Software\rtltcpaccess] "address"="192.168.1.1" "port"=dword:00009999 "testmode"=dword:00000000
address is a string, port is a DWORD. If the testmode is enabled it checks for lost samples, just like rtl_test.
