## 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.

RECS_DIR=$HOME/BirdSongs

## REC_CARD is the sound card you would want the birdnet_recording.service to
## use. Leave this as "default" to use PulseAudio (recommended), or use
## the output from "aplay -L" to specify an ALSA device.

REC_CARD=default

## 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=$HOME/BirdSongs/Processed

## EXTRACTED is the directory where the extracted audio selections are moved.

EXTRACTED=$HOME/BirdSongs/Extracted

## 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

## SENSITIVITY is the detection sensitivity from 0.5-1.5.

SENSITIVITY=1.25

## CHANNELS holds the variable that corresponds to the number of channels the
## sound card supports.

CHANNELS=2

## FULL_DISK can be set to configure how the system reacts to a full disk
## purge = Remove the oldest day's worth of recordings
## keep = Keep all data and 'stop_core_services.sh'

FULL_DISK=purge

## PRIVACY_THRESHOLD can be set to enable sensitivity to Human sounds. This
## setting is an effort to introduce privacy into the data collection.
## The PRIVACY_THRESHOLD value represents a percentage of the entire species
## list used during analysis. If a human sound is predicted anywhere within
## the precentile set below, no data is collected for that audio chunk.
## Valid range: 0-3

PRIVACY_THRESHOLD=0

## RECORDING_LENGTH sets the length of the recording that BirdNET-Lite will
## analyze.

RECORDING_LENGTH=15

## EXTRACTION_LENGTH sets the length of the audio extractions that will be made
## from each BirdNET-Lite detection. An empty value will use the default of 6
## seconds.

EXTRACTION_LENGTH=

## AUDIOFMT set the audio format that sox should use for the extractions.
## The default is mp3. Available formats are: 8svx aif aifc aiff aiffc al amb
## amr-nb amr-wb anb au avr awb caf cdda cdr cvs cvsd cvu dat dvms f32 f4 f64 f8
