 # Digital Speech Decoder - Florida Man Edition
 
-DSD-FME is an evolution of the original DSD project from 'DSD Author' using the base code of [szechyjs](https://github.com/szechyjs/dsd "szechyjs"), some code and ideas from [LouisErigHerve](https://github.com/LouisErigHerve/dsd "LouisErigHerve"), [Boatbod OP25](https://github.com/boatbod/op25 "Boatbod OP25") and

-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, ilyacodes, 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.

-## 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:
-
-Start up all three of these in sequence.
-
-Terminal #1 (connecting to SDR++):
-`dsd-fme -fi -i tcp:127.0.0.1:7355 -o - | socat stdio tcp-listen:7300,forever,reuseaddr`
-
-Terminal #2:
-`dsd-fme -fZ -8 -M M17:2:NXDN:M17:8000 -i tcp:127.0.0.1:7300 -o - | socat stdio tcp-listen:7301,forever,reuseaddr`
-
-Terminal #3:
-`dsd-fme -fz -i tcp:127.0.0.1:7301`
-
-Note: Transmuting only carries over voice when audio is output, and will not carry any ID values, or any other data payloads.
-This mode is only meant for educational or fun purposes, please do not retransmit stuff that doesn't belong to you.

-### 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.
-
-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:
+### LD_PATH
 
+Some environments may require an LD path to be set to /usr/local/lib, similar to:
 ```
-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
+LD_LIBRARY_PATH=/usr/local/lib
+export LD_LIBRARY_PATH
 ```
 
-Then manually install ITPP and MBElib, see above install notes. Be sure to run `cp libmbe* /usr/lib` after compiling MBElib.
+### macOS Builds (Homebrew)
 
-Then you can build and install using
+Building on macOS (Apple Silicon) using [Homebrew](https://brew.sh "Homebrew") for dependencies has been tested working, but keep in mind this project is primarily focused on Linux, so macOS support should be considered experimental. Unlike the Linux steps above, macOS has no `ldconfig`, so simply skip that step wherever it appears below.
+
+Install dependencies first:
+
+```
+brew install cmake git libsndfile pulseaudio rtl-sdr codec2 ncurses pkg-config
+```
+
+Note: Homebrew's ncurses is keg-only (not symlinked into /opt/homebrew), so we will pass an extra CMake flag when configuring DSD-FME below so it can be found.
+
+MBELib is considered a requirement in this build. You must read this notice prior to continuing. [MBElib Patent Notice](https://github.com/lwvmobile/mbelib#readme "MBElib Patent Notice")

+Pulse Audio is still the default input/output in DSD-FME, so start the Homebrew Pulse Audio daemon before running dsd-fme (it will also restart at login): `brew services start pulseaudio`. To confirm your RTL-SDR dongle is detected, run `rtl_test` (ships with Homebrew's rtl-sdr package); unlike Linux, there is no driver blacklist to deal with on macOS.
+
+### Windows Cygwin Builds
+
+Cygwin builds now have an experimental semi-automatic installer, to run, follow steps below:
+
+Open Windows PowerShell (not Command Prompt) and copy and paste all of this in all at once.
+
+```
+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
+
+```
+
+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.
+
+Then:
+
+```
+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`.

-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.

+Scanning Option Examples:
+
+  Scanning will not perform quickly like a real scanner, but can be used with any
+  supported decoding type and analog as well, and will require a channel_map to scan frequencies
