[discrete] == Introduction

This repo contains BirdNET models and scripts for processing large amounts of audio data or single audio files. This is the most advanced version of BirdNET for acoustic analyses and we will keep this repository up-to-date with new models and improved interfaces to enable scientists with no CS background to run the analysis.

You can access the map here: https://kahst.github.io/BirdNET-Analyzer/projects.html[Open projects map]

== Model version update

[discrete] ==== V2.4, June 2023

• more than 6,000 species worldwide
• covers frequencies from 0 Hz to 15 kHz with two-channel spectrogram (one for low and one for high frequencies)
• 0.826 GFLOPs, 50.5 MB as FP32
• enhanced and optimized metadata model
• global selection of species (birds and non-birds) with 6,522 classes (incl. 10 non-event classes)

You can find a list of previous versions here: https://github.com/kahst/BirdNET-Analyzer/tree/main/checkpoints[BirdNET-Analyzer Model Version History]

[discrete] ==== Species range model V2.4 - V2, Jan 2024

• updated species range model based on eBird data
• more accurate (spatial) species range prediction
• slightly increased long-tail distribution in the temporal resolution
• see https://github.com/kahst/BirdNET-Analyzer/discussions/234[this discussion post] for more details

== Technical Details

Model V2.4 uses the following settings:

• 48 kHz sampling rate (we up- and downsample automatically and can deal with artifacts from lower sampling rates)
• we compute 2 mel spectrograms as input for the convolutional neural network: ** first one has fmin = 0 Hz and fmax = 3000; nfft = 2048; hop size = 278; 96 mel bins ** second one has fmin = 500 Hz and fmax = 15 kHz; nfft = 1024; hop size = 280; 96 mel bins
• both spectrograms have a final resolution of 96x511 pixels
• raw audio will be normalized between -1 and 1 before spectrogram conversion
• we use non-linear magnitude scaling as mentioned in http://ceur-ws.org/Vol-2125/paper_181.pdf[Schlüter 2018]
• V2.4 uses an EfficienNetB0-like backbone with a final embedding size of 1024
• See https://github.com/kahst/BirdNET-Analyzer/issues/177#issuecomment-1772538736[this comment] for more details

== Setup === Setup (Raven Pro)

If you want to analyze audio files without any additional coding or package install, you can now use https://ravensoundsoftware.com/software/raven-pro/[Raven Pro software] to run BirdNET models. After download, BirdNET is available through the new "Learning detector" feature in Raven Pro.
