Secure, reliable, automated processing

The Pipeline uses cutting-edge machine learning techniques and cloud computing to automate the processing of audible and ultrasonic audio data, providing a platform that can scale to accommodate acoustic monitoring projects of any size.

Advanced ID algorithms designed by species experts

The species identification algorithms in the BTO Acoustic Pipeline deliver unique and unrivalled performance for birds, bats and other wildlife. They’ve been developed by Dr Stuart Newson and Dr Simon Gillings in collaboration with experts throughout Europe, distilling years of audio recording and first-hand experience.

Trusted by thousands of people in over 20 countries

Since its launch in 2021, the Pipeline has processed over 500 terabytes of audio recordings from more than 2000 users in 25 countries in Europe and beyond. The BTO Acoustic Pipeline has supported county councils, National Parks, rewilding projects and NGOs to audit their biodiversity.

For commercial use, academic research and citizen science

The Pipeline has been used for a wide range of commercial projects, citizen science projects and bioacoustics research. The Pipeline is trusted by over 100 ecological consultancies including some of the biggest players in the UK, enhancing the quality of data used to inform planning decisions.

Free support from experts in the field

Our Acoustic Pipeline Support Hub is available for free before you even begin recording. It provides a range of guides and advice to ensure a smooth and easy end-to-end workflow for acoustic monitoring.

Support from our in-house experts Dr Simon Gillings and Dr Stuart Newson is also available from acoustic.pipeline [at]

Choose from free or paid plans, and bespoke projects

The Pipeline is provided for free, subject to fair usage and data sharing conditions.

A range of scalable, pay-as-you-go plans for greater processing capacity are available. And for commercial and large-scale use, bespoke paid Pipeline Projects provide additional data management options.
