# Configuration settings for BirdNET as a service #
################################################################################
#___________The four variables below are the only that are required.___________#
## BIRDNET_USER should be the non-root user systemd should use to execute each
## service.
BIRDNET_USER=pi
## RECS_DIR is the location birdnet_analysis.service will look for the data-set
## it needs to analyze. Be sure this directory is readable and writable for
## the BIRDNET_USER. If you are going to be accessing a remote data-set, you
## still need to set this, as this will be where the remote directory gets
## mounted locally. See REMOTE_RECS_DIR below for mounting remote data-sets.
RECS_DIR=${HOME}/BirdSongs
## LATITUDE and LONGITUDE are self-explanatroy. Find them easily at
## maps.google.com. Only go to the thousanths place for these variables
## Example: these coordinates would indicate the Eiffel Tower in Paris, France.
## LATITUDE=48.858
## LONGITUDE=2.294
LATITUDE="${LATITUDE}"
LONGITUDE="${LONGITUDE}"

#___________________systemd.mount for analysis, extraction,____________________#
#______________________________or file-serving_________________________________#
# Leave these settings EMPTY if your data-set is local. #
## REMOTE is simply a setting for enabling the systemd.mount to use a remote

## REMOTE_USER is the user SSH will use to connect to the REMOTE_HOST.
REMOTE_USER=
## REMOTE_RECS_DIR is the directory on the REMOTE_HOST which contains the

## that.

#____________to your data,(e.g., extractions, raw data, live___________________#
#______________audio stream, BirdNET.selection.txt files)______________________#
# Leave these EMPTY if you do not want to enable web access #
## EXTRACTIONS_URL is the URL where the extractions, data-set, and live-stream
## will be web-hosted. If you do not own a domain, or would just prefer to keep
## BirdNET-system on your local network, you can set this to http://localhost.
## Setting this (even to http://localhost) will also allow you to enable the
## GoTTY web logging features below.
EXTRACTIONS_URL=http://raspberrypi.local
## CADDY_PWD is the plaintext password (that will be hashed) and used to access
## the "Processed" directory and live audio stream. This MUST be set if you
## choose to enable this feature.
CADDY_PWD=${CADDY_PWD}

#-------------------------------- Defaults ----------------------------------#
#______The six variables below are default settings that you (probably)________#
#__________________don't need to change at all, but can._______________________#
## REC_CARD is the sound card you would want the birdnet_recording.service to
## use. This setting is irrelevant if you are not planning on doing data
## collection via recording on this machine. The command substitution below
## looks for a USB microphone's dsnoop alsa device. The dsnoop device lets
## birdnet_recording.service and livestream.service share the raw audio stream
## from the microphone. If you would like to use a different microphone than
## what this produces, or if your microphone does not support creating a
## dsnoop device, you can set this explicitly from a list of the available
## devices from the output of running 'aplay -L'
REC_CARD="\$(sudo -u pi aplay -L \
| grep dsnoop \
| cut -d, -f1 \
| grep -ve 'vc4' -e 'Head' -e 'PCH' \
| uniq)"
## PROCESSED is the directory where the formerly 'Analyzed' files are moved
## after extractions have been made from them. This includes both WAVE and
## BirdNET.selection.txt files.
PROCESSED=${RECS_DIR}/Processed
## EXTRACTED is the directory where the extracted audio selections are moved.
EXTRACTED=${RECS_DIR}/Extracted
## IDFILE is the file that keeps a complete list of every spececies that
## BirdNET has identified from your data-set. It is persistent across
## data-sets, so would need to be whiped clean through deleting or renaming
## it. A backup is automatically made from this variable each time it is
## updated (structure: ${IDFILE}.bak), and would also need to be removed
## or renamed to start a new file between data-sets. Alternately, you can
## change this variable between data-sets to preserve records of disparate
## data-sets according to name.
IDFILE=${HOME}/BirdNET-system/IdentifiedSoFar.txt
## OVERLAP is the value in seconds which BirdNET should use when analyzing
## the data. The values must be between 0.0-2.9.
OVERLAP="0.0"
## CONFIDENCE is the minimum confidence level from 0.0-1.0 BirdNET's analysis
## should reach before creating an entry in the BirdNET.selection.txt file.
## Don't set this to 1.0 or you won't have any results.
CONFIDENCE="0.7"
################################################################################
#------------------------------ Auto-Generated ------------------------------#
#_____________________The variables below are auto-generated___________________#
#______________________________during installation_____________________________#
## CHANNELS holds the variabel that corresponds to the number of channels the
## sound card supports.
CHANNELS=$(awk '/CHANN/ { print $2 }' ${SOUND_PARAMS} | sed 's/\r$//')
# Don't the three below
## ANALYZED is where the extraction.service looks for audio and
## BirdNET.selection.txt files after they have been processed by the
## birdnet_analysis.service. This is NOT where the analyzed files are moved --
## analyzed files are always created within the same directory
## birdnet_analysis.service finds them.
ANALYZED=${RECS_DIR}/*/*Analyzed
## SYSTEMD_MOUNT is created from the RECS_DIR variable to comply with systemd
## mount naming requirements.
SYSTEMD_MOUNT=$(echo ${RECS_DIR#/} | tr / -).mount
## VENV is the virtual environment where the the BirdNET python build is found,
