audioBlast
Search recordings alongside their annotations, analyses and traits, from species to soundscapes.
Open resources for bioacoustics and ecoacoustics
Search and browse the world’s animal sound recordings, look up the terms used to describe them, and build on open data, vocabularies and software.
Recordings and data
audioBlast
audioBlast aims to make the world’s collections of bioacoustic and ecoacoustic recordings findable, accessible and searchable, with the taxa, traits, references, specimens and locations that describe them.
browse.acousti.cloud
Browse by taxon
A page for each taxon with recordings in audioBlast, arranged by the Catalogue of Life classification, with its recordings, how its sound has been written down, and links to the analysis viewer.
api.audioblast.org
audioBlast API
Query recordings, annotations, taxa and traits, and analysis results such as acoustic indices and BirdNET identifications, as JSON, or let an AI assistant query them through the MCP server.
vocab.audioblast.org
audioBlast Vocabulary Server
Controlled vocabularies for describing animal sounds and how they are recorded, from call types and sound production methods to recording devices.
Resources
Terms and quotations
glossary.acousti.cloud
Bioacoustics & Ecoacoustics Glossary
Definitions of terms used in bioacoustics and ecoacoustics, with references, synonyms and related terms.
quotes.acousti.cloud
Quotes on bioacoustics
An R package, bioacousticsquotes, that generates random quotations from a database of quotes on bioacoustics and ecoacoustics.
Software
R packages
Packages for working with bioacoustic and ecoacoustic recordings in R.
revamp.ebaker.me.uk
ReVAMP
An R interface to the Vamp audio analysis plugins, for running plugins such as acoustic indices and onset detection on recordings and getting the results as data frames.
sonicscrewdriver.ebaker.me.uk
SonicScrewdriveR
A toolset in R for the analysis and visualisation of bioacoustic and ecoacoustic datasets.
Tools
Web-ready bioacoustics
Open-source plugins for wavesurfer.js, and a WebAssembly host for Vamp plugins, that bring bioacoustic recordings, annotations, spectrograms and analysis to the browser. They power the players on audioBlast and BioAcoustica.
wavesurfer-annotations
wavesurfer-annotations
A wavesurfer.js plugin that shows a recording’s annotations: boxes bounded in time and frequency on the spectrogram, linked to regions on the waveform.
wavesurfer-tiled-spectrogram
wavesurfer-tiled-spectrogram
A wavesurfer.js plugin that shows a precomputed spectrogram from image tiles, loading only those in view, so long and ultrasonic recordings appear at once.
vamp-wasm
vamp-wasm
A WebAssembly host for Vamp audio analysis plugins, to run them in a web browser or Node.js and analyse a recording without a server.
Open data
Reuse the data
The glossary is published under a CC BY 4.0 licence, and software can read it as well as people. The audioBlast API and Vocabulary Server offer the same kinds of access.
JSON APIs
Query audioBlast’s recordings, taxa and traits, or search the glossary and vocabularies for a term by name or acronym and fetch its definition and references by its URI.
Linked data
Download the whole glossary as a SKOS concept scheme, or request any term as RDF from its own URI.
MCP servers
Let AI assistants such as Claude search recordings, taxa and traits, and read the definitions of terms and their references, through the Model Context Protocol. Each server is read-only.
- audioBlast API: the recordings, taxa, traits, references, specimens and locations
- Vocabulary Server: the terms for calls, sound production and recording methods
- Glossary: the terms of bioacoustics and ecoacoustics
