 # 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 [Osmocom OP25](https://gitea.osmocom.org/op25/op25 "Osmocom OP25"), along with other snippets of code, information, and inspirations from other projects including [DSDcc](https://github.com/f4exb/dsdcc "DSDcc"), [SDRTRunk](https://github.com/DSheirer/sdrtrunk "SDRTrunk"), [MMDVMHost](https://github.com/g4klx/MMDVMHost "MMDVMHost"), [LFSR](https://github.com/mattames/LFSR "LFSR"), [OK-DMRlib](https://github.com/OK-DMR/ok-dmrlib "OK-DMRlib"), and [EZPWD-Reed-Solomon](https://github.com/pjkundert/ezpwd-reed-solomon "EZPWD"), Eric Cottrell, SP5WWP, ilyacodes, Phillipw1084 and others. Finally, this is all brought together with original code to extend the fuctionality and add new features including NCurses Terminal and Menu system, Pulse Audio, TCP Direct Link Audio, RIGCTL, Trunking Features, LRRP/GPS Mapping, P25 Phase 2, EDACS, YSF, M17, OP25 Capture Bin compatability, etc. DSD-FME is primarily focused with Linux Desktop users in mind, so please understand that this version may not compile, compile easily, or run correctly in other environments.

-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

-
-=======[ Output Device #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. -->

-## Conventional Frequency Scanner
+## New -- Experimental Conventional Frequency "Fast Scanner"
-This feature is used to allow DSD-FME to use RIGCTL or RTL input and cycle through frequencies to attain a frame sync. 
+This feature is used to allow DSD-FME to use RIGCTL or RTL input and cycle through frequencies as fast as possible to attain a frame sync. 
 
-This works almost identically to how the trunkng methods work, but instead of locking onto a control channel and tuning based on its decoding, it tunes through all loaded frequencies in a CSV file and stops when it finds a frame sync. This method is meant for loading a bunch of conventional non-trunking frequencies that signal only when voice or short data bursts are present (DMR T2, Conventional P25 P1, Conventional NXDN, etc) and decode them until the frame sync stops and then resume its scan. This method uses SDR++ RIGCTL, or RTL internal handling to go through signal. -Y is the scan switch. Note: This method will NOT perform at a level similar to a real hardware scanner, SDR tuning is not nearly as fast or reliable at locking onto signal.

-The Channel Map setup will be identical to any of the channel maps found for trunking systems, channel numbers do not matter and can be arbitrarily organized, and frequencies can be duplicated to be 'scanned' more frequently in larger CSV files. Scan speed by default is 1 second, and is most stable at that speed. This can be adjusted by using the `-t 2` option, for example, to specify 2 seconds of hang time per frequency. ~~If activity occurs on a frequency, an additional 2 seconds of 'hangtime' will occur on that frequency for any follow up voice activity.~~ Using `-t 0` will forego the one second wait time, and this can work in some situations, but is not advised as it may skip during the middle of transmissions, or skip over them entirely without a framesync.
+The Channel Map setup will be identical to any of the channel maps found for trunking systems, channel numbers do not matter and can be arbitrarily organized, and frequencies can be duplicated to be 'scanned' more frequently in larger CSV files. Scan speed is purely set by your CPU/GPU, and also by other factors like using SDR++ server to connect to a SDR++ client, or RTL_TCP server to client, etc, so faster computers scan faster, and slower will scan slower, slower scans may require multiple duplicate entries into your scanner csv file if you make a really large one.

-Trunking Note3: DMR Trunking has been coded, and some testing and tweaks have been carried out. Cap+, Con+, and TIII systems seem to do well with trunking now. Placing the frequency for the control channel at channel map 0 in your channel_map.csv file is not required now if using RIGCTL or the RTL Input, both can poll the VFO for the current frequency if it believes its on a control channel, but setting a fake channel number (i.e. 999) first with the CC frequency will result in finding the CC faster on startup if desired. If you need to map out your channels for TIII, you can observe the console output and look for channel numbers. For conveniece I have included the DSDPlus style LSN-esque numbering into the console print so it will make it easier for users from DSDPlus to map frequencies into the channel_map.csv file. Make sure your channel numbers are the lpcn (12-bit logical physical channel number - decimal format) values from the log, and not the LPCN+TS (13-bit DSDPlus LSN) values. Notice: TIII Site ID value needs work to determine proper DMRLA values for system area and sub area.

+Trunking Note4: NXDN Trunking v1 will require a channel map. Please see the example folder for an appropriate channel map.

-## Sending Audio to UDP Target/Port
-
-Audio can be sent to a target address on your local area network with the UDP blaster using the `-o udp:targetaddress:port` option.
-Note: Any analog audio monitoring will not function properly over UDP port (rate difference issues)
-
-Example (Short 8k/2):
-`dsd-fme -fs -o udp:192.168.7.8:23470`
-
-Receiving End (Short 8k/2):
-`socat stdio udp-listen:23470 | play --buffer 640 -q -b 16 -r 8000 -c2 -t s16 -`
-
-Example (Short 8k/1):
-`dsd-fme -f1 -o udp:192.168.7.8:23469`
-
-Receiving End (Short 8k/1):
-`socat stdio udp-listen:23469 | play --buffer 320 -q -b 16 -r 8000 -c1 -t s16 -`
-
-Example (Float 8k/2):
-`dsd-fme -ft -y -o udp:192.168.7.8:23468`
-
-Receiving End (Float 8k/2):
-`socat stdio udp-listen:23468 | play --buffer 1280 -q -b 16 -r 8000 -c2 -t f32 -`
-
-Example (Float 8k/1):
-`dsd-fme -fi -y -o udp:192.168.7.8:23467`
-
-Receiving End (Float 8k/1):
-`socat stdio udp-listen:23467 | play --buffer 640 -q -b 16 -r 8000 -c1 -t f32 -`
-
-Note: --buffer option in play is calculated by (channels * samples * sizeof(samples)), 
-where samples is 160 for mono, 320 for stereo, and short samples are 2 and float samples are 4.
-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.

+Optional 'Virtual Sinks' for routing audio from SDR++ or GQRX, Media Players, etc. into DSD-FME
 
-### LD_PATH
+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.
-
-Some environments may require an LD path to be set to /usr/local/lib, similar to:
-```
-LD_LIBRARY_PATH=/usr/local/lib
-export LD_LIBRARY_PATH
-```
-
-### macOS Builds (Homebrew)
-
-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")
-
-```
-git clone https://github.com/lwvmobile/mbelib
-cd mbelib
-git checkout ambe_tones
-mkdir build
-cd build
-cmake ..
-make -j `sysctl -n hw.ncpu`
-sudo make install
-cd ../..
-```
-
-Finish by cloning and building DSD-FME (note the added -DCMAKE_PREFIX_PATH flag for keg-only ncurses):
-
-```
-git clone https://github.com/lwvmobile/dsd-fme
-cd dsd-fme
-mkdir build
-cd build
-cmake .. -DCMAKE_PREFIX_PATH=$(brew --prefix ncurses)
-make -j `sysctl -n hw.ncpu`
-sudo make install
-```
-
-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`.
-
-### 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. You may need to manually install either of these programs manually, if desired, or find suitable alternatives for pipewire-pulse such as pwvucontrol, or similar.

-### Applying Patches -- Recommended For Advanced Users Only
+If the call alert wav files aren't playing, then make sure to run the following in the dsd-fme folder to copy the wav files to the /usr/share/ folder and give them adequate permission to be accessed.
-
-More experimental or potentially functionality changing or temperamental features may be included as seperate .patch files inside of the patch folder, and are not included in the source code by default. 
-If users wish to try or use these patches, then they can apply patches and build/rebuild with the following procedure. Make sure you have changed to the dsd-fme directory first, either by the top
-command, or by otherwise opening the terminal to the clone folder.
 
 ```
-cd dsd-fme
+sudo cp tone8.wav /usr/share/
-git apply patch/patchname.patch
+sudo cp tone24.wav /usr/share/
-cd build
+sudo cp tone48.wav /usr/share/
-make
+sudo chmod 777 /usr/share/tone8.wav
-sudo make install
+sudo chmod 777 /usr/share/tone24.wav
-```
+sudo chmod 777 /usr/share/tone48.wav
-
+```
-If you later wish to update to the latest version via `git pull`, you may first need to reset any patches, perform the `git pull`, and then reapply patches.
-A procedure for this is similar to, but not limited to:
-
-```
-cd dsd-fme
-git reset --hard
-git pull
-git apply patch/xyz.patch
-cd build
-make
-sudo make install
-```
-
-NOTE: Patches can potential break over time with further changes to code, requiring merge resolution or other manual intervention to re-apply patches.
