-This project wouldn't be possible without a few good people providing me plenty of sample audio files to run over and over again. Special thanks to jurek1111, KrisMar, noamlivne, racingfan360, iScottyBotty, LimaZulu, Forts, thewraithe2008, RayAir, Cretu, and others for the many hours of wav samples and information provided by them. Most importantly, HRH17, whose insight, information, samples, and willingness to let me remote into a computer half-way across the globe in order to test trunking features are what make DSD-FME what it has become. I'd also like to thank mrscanner2008 for providing an additional remote where additional NXDN Type-C, 'Idas' Type-D, and XPT decoding and trunking could be sorted out. Thanks to volo-zyko for cleaning up a lot of code. Thank you everybody.

+## Audio Plumbing
+
+While using DSD-FME to demodulate and decode RF Audio, you will find it necessary to properly plumb (or route) audio from each input source and output sink properly. This mini tutorial aims to help you do such when using Pulse Audio.
+
+You will first want to locate and run the virtualsink.sh script file via `sh virtualsink.sh` command. This will create two null-sink, or 'virtual sinks' for us to plumb audio from point A to point B. 
+
+Here are screenshots of a proper setup using pavucontrol, or "Pulse Audio Volume Control", having voice input from the encoder listening to your microphone, the RF Output going into the "Virtual_Sink" null-sink, and on the playback side, playing back voice to our speakers, with RF modulated audio being monitored on "Virtual-Sink" null-sink.
+
+![Audio 1](https://github.com/lwvmobile/dsd-fme/blob/aw_dev/examples/pavucontrol_plumbing1.png)
+
+![Audio 2](https://github.com/lwvmobile/dsd-fme/blob/aw_dev/examples/pavucontrol_plumbing2.png)
+
+The general idea is that we want to route RF modulated audio into our Virtual_Sink and have our decoder listen to the same sink. Voice Output should always be to Audio Hardware (speakers, headphones, etc).
+
+Note, that using the virtualsink.sh will create these sinks for us for the duration of your computers boot. If you reboot, they will not persist. Configuration files can be modified to always have these sinks available, or the `virtualsink.sh` script can be executed on login, but you must do so at your own risk and own research, it is out of the scope of this tutorial to create persistent sinks.
+
+In case of the usage of a headless environment and pavucontrol is not viable, you may use alternatives such as pulsemixer which is similar in functionality, just as a CLI tool and not a GUI tool.
+
+Users can now use the `-O` CLI argument to list out all pulse audio input sources and output sinks and pass an optional argument alongside `pulse`, appending the name or index number to select the device each time. This method will work in both Linux environments as well as Cygwin builds (making sure to start the pulseaudio.exe server in the back first with the specified .bat file or command, see below).
+
+For Example:
+
+The Output (truncated) of `dsd-fme -O`
+
+```
+=======[ Output Device #1 ]=======
+Description: Family 17h (Models 00h-0fh) HD Audio Controller Analog Stereo
+Name: alsa_output.pci-0000_0d_00.3.analog-stereo
+Index: 1
+
+=======[ Output Device #4 ]=======
+Description: Virtual_Sink1
+Name: virtual_sink1
+Index: 4
+
+=======[ Output Device #5 ]=======
+Description: Virtual_Sink2
+Name: virtual_sink2
+Index: 5
+
+=======[ Input Device #2 ]=======
+Description: Family 17h (Models 00h-0fh) HD Audio Controller Analog Stereo
+Name: alsa_input.pci-0000_0d_00.3.analog-stereo
+Index: 2
+
+=======[ Input Device #5 ]=======
+Description: Monitor of Virtual_Sink1
+Name: virtual_sink1.monitor
+Index: 5
+
+=======[ Input Device #6 ]=======
+Description: Monitor of Virtual_Sink2
+Name: virtual_sink2.monitor
+Index: 6
+```
+
+You might use any of the following for input and output options:
+
+```
+-i pulse
+-i pulse:6
+-i pulse:virtual_sink2.monitor
+
+-o pulse
+-o pulse:1
+-o pulse:alsa_output.pci-0000_0d_00.3.analog-stereo
+```
+
+Something to keep in mind is that often times, you only need to set these values once, as a pulse audio server (or plugin) can often times remember these settings, even across reboots, as long as the same hardware is present for future use (real or null-sink).
+
+<!-- TODO: Add This later -->
+<!-- Cygwin Note: Running the supplied `0p - start-pulse-audio-backend.bat` file will not only start up the pulse audio server for you, but also setup your null-sinks, and enumerate all devices for you to use, making it an easy selection for your start up .bat files. See any notes in the precomplied .zip file for more information. -->

 This is vital to prevent 'lag' or cut-off audio when the UDP audio doesn't fill the default buffer size.
 
 Note2: Be sure to start the receiving end AFTER starting DSD-FME. If DSD-FME is restarted, make sure to restart the receiving end as well, as socat/UDP closes the UDP port listening when DSD-FME closes the UDP socket.
+
+Note3: socat version 1.8 may have a `E xioopen_ipdgram_listen(): unknown address family 0` problem, downgrading to 1.7.4 is recommended if this occurs. `sudo downgrade socat`.
+
+## Record 48k/1 audio with rtl_fm
+
+You can record suitable audio to feed as input to dsd-fme with `-i` using rtl_fm:
+
+`rtl_fm -M nfm -f [FREQ] -s 48k -g 42 -l 20 > input.wav`
+
+You can also combine that with `socat` to send the audio to a remote dsd-fme instance in real time while keeping a local copy on the host where the RTL-SDR dongle is:
+
+`rtl_fm -M fm -f [FREQ] -s 48k -g 42 -l 20 | tee input.wav | socat -u - TCP-LISTEN:1234,forever,reuseaddr`
+
+On the remote side where dsd-fme is, use the TCP input:
+
+`dsd-fme -i tcp:192.168.7.8:1234 -N`
+
+Note: As always, when using rtl_fm, play with `-l` and `-g` to find a good squelch and gain values for your environment - you will know if the squelch is the right value when `input.wav` does not increase in size in the absence of useful signal on the monitored frequency.
+
+## Using the Experimental M17 Encoder (and Decoder)
+
+You can use the experimental M17 Voice Stream and Packet encoder with the following examples.
+
+Encode/Decode Local Feedback Voice Stream (Single Session):
+
+`dsd-fme -fZ -i pulse -o pulse -M M17:3:SP5WWP:BROADCAST:48000`
+
+Using the `-8` option (raw audio monitor) will instead send encoded raw audio to output instead of decoded audio. For example,
+
+To send a voice stream out of stdout into SOCAT TCP to a second/remote DSD-FME session to decode:
+
+Encode (Upper Z):
+
+`dsd-fme -fZ -8 -i pulse -M M17:9:LWVMOBILE:DSD-FME:48000 -o - | socat stdio tcp-listen:7355,forever,reuseaddr`
+
+Decode (Lower z): 
+
+`dsd-fme -fz -i tcp:192.168.7.8:7355`
+
+NOTE: When using tcp input for M17 decoding, DSD-FME will keep the TCP connection alive with constant retries, so no need to restart the decoding session on connection failure.
+
+SMS Packet Encoder (Text Only):
+
+`dsd-fme -fP -8 -S "This is a sample message sent over M17 Packet Data using DSD-FME to encode it."`
+
+SMS Packet Encoder (over SOCAT TCP):
+
+`dsd-fme -fP -8 -S "This is a sample message sent over M17 Packet Data using DSD-FME to encode it and SOCAT to send it over TCP." -o - | socat stdio tcp-listen:7355,forever,reuseaddr`
+
+Many combinations of input and output can be used as well, and using features like raw audio saving with `-6 m17str.wav` will save a wav file of your encoded audio to be replayed later with `-i m17str.wav`
+Also note, features function similarly, like -Z for payload, and input options include pulse, oss, stdin, rtl, tcp, etc, using those as the mic in for voice encoding. With the right setup of input/output/input using SOCAT TCP pipes, it is conceivable to use DSD-FME to convert analog audio from NFM into M17 audio, or even change another digital format supported by DSD-FME into M17 audio, if desired (purely for research and fun purposes). Ncurses terminal will function with internal encoder/decoder and wav file creation, with toggle encode/tx with `\` key, but will not function with stdout properly.
+
+The `-M` switch is used to specify user M17 variables, the string is in the format of M17:CAN:SRC:DST:INPUT_RATE.
+CAN 1-15; SRC and DST have to be no more than 9 UPPER base40 characters.
+BASE40: '  ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789-/.'
+Input Rate Default is 48000; Use Multiples of 8000 up to 48000.
+Values not entered into the M17: string are set to default values. M17:7:DSD-FME:DSD-FME:48000
+
+Fun Example Transmuting OTA Analog Things into M17:
+
+Start up in sequence.
+
+Terminal #1 (RTL Input):
+`dsd-fme -fZ -8 -M M17:1:ANALOG:M17:48000 -i rtl:0:162.425M -o - | socat stdio tcp-listen:7310,forever,reuseaddr`
+
+Terminal #2:
+`dsd-fme -fz -i tcp:127.0.0.1:7310`
+
+Fun Example Transmuting OTA Digital Things into M17:
+

 ### Windows Cygwin Builds
 
-If using RTL input support, you must install libusb-win32 before proceeding with Cygwin installation. You will also need to build and compile a version of librtlsdr, but this can be tricky, and personally, I had to resort to using a much older version of the source code to get it to build at all with the rtl support in the precompiled 'Aero' builds.
+Cygwin builds now have an experimental semi-automatic installer, to run, follow steps below:
 
-Then install all dependencies available in the repo prior to building, either directly selecting them during setup with the setup-x86.exe or setup-x64.exe or by issuing a command similar to this:
+Open Windows PowerShell (not Command Prompt) and copy and paste all of this in all at once.
 
 ```
-setup-x64.exe --packages libpulse-devel,libpulse-mainloop-glib0,libpulse-simple0,libpulse0,pulseaudio,pulseaudio-debuginfo,pulseaudio-equalizer,pulseaudio-module-x11,pulseaudio-module-zeroconf,pulseaudio-utils,sox-fmt-pulseaudio,xfce-pulseaudio-plugin,libusb0,libusb1.0,libusb1.0-debuginfo,libusb1.0-devel,libncurses++w10,libncurses-devel,libncursesw10,ncurses,cmake,gcc-core,gcc-debuginfo,gcc-objc,git,make,socat,sox,sox-fmt-ao,unzip,wget,gcc-g++,libsndfile-devel
+Invoke-WebRequest https://cygwin.com/setup-x86_64.exe -OutFile setup-x86_64.exe

+.\setup-x86_64.exe --packages nano,libpulse-devel,libpulse-mainloop-glib0,libpulse-simple0,libpulse0,pulseaudio,pulseaudio-debuginfo,pulseaudio-equalizer,pulseaudio-module-x11,pulseaudio-module-zeroconf,pulseaudio-utils,sox-fmt-pulseaudio,libusb0,libusb1.0,libusb1.0-debuginfo,libusb1.0-devel,libncurses++w10,libncurses-devel,libncursesw10,ncurses,cmake,gcc-core,gcc-debuginfo,gcc-objc,git,make,socat,sox,sox-fmt-ao,zip,unzip,wget,gcc-g++,libsndfile-devel
-
-Then manually install ITPP and MBElib, see above install notes. Be sure to run `cp libmbe* /usr/lib` after compiling MBElib.
-
-Then you can build and install using
 
 ```
-git clone https://github.com/lwvmobile/dsd-fme
+
-cd dsd-fme
+Pick a Mirror. http://www.gtlib.gatech.edu mirror seems relatively fast. Nurse the Cygwin installer by clicking next and waiting for it to finish. Ignore the warning popup telling you to install libusb from sourceforge. Install the [Zadig](https://zadig.akeo.ie/ "Zadig") driver instead, if you haven't already and have an RTL Dongle. After Cygwin finishes installing, the installer sh script will download and run, be patient, it may also take a little while.
-mkdir build
+
-cd build
+Then:
-# -DAERO=ON is optional, but recommended if you want the older OSS support as well
+
-cmake -DAERO=ON ..
-make
-make install
 ```
+C:\cygwin64\bin\mintty.exe /bin/bash -l -c "wget https://raw.githubusercontent.com/lwvmobile/dsd-fme/refs/heads/audio_work/download-and-install-cygwin.sh; sh download-and-install-cygwin.sh; dsd-fme;"
+
+```
+
+After the sh script finishes, dsd-fme should open. If not, then double click on the Cygwin Terminal desktop shortcut, and try running `dsd-fme`. If you chose to create a portable version, you will find the folder and zip file in the `C:\cygwin64\home\username` directory if using the default cygwin64 folder location.
+
+You can also update your versions by using the cyg_rebuild.sh script `sh cyg_rebuild.sh`.
 
 ### Virtual Sinks
 
-You may wish to direct sound into DSD-FME via Virtual Sinks. You may set up a Virtual Sink or two on your machine for routing audio in and out of applications to other applications using the following command, and opening up pavucontrol "PulseAudio Volume Control" in the menu (or `pulsemixer` in headless mode) to change line out of application to virtual sink, and line in of DSD-FME to monitor of virtual sink. This command will not persist past a reboot, so you will need to invoke them each time you reboot, or search for how to add this to your conf files for persistency if desired. Note: This setup is completely optional if using TCP Network Sink Audio and/or RTL Input.
