Swift autonomous recording units are our main platform for collecting terrestrial passive acoustic data for research and conservation. The vision behind developing Swift units was to build a small, lightweight, and cost-effective acoustic recorder that is low cost and easy to use. In addition to supporting researchers, the Swift platform enables hobbyists and enthusiasts from around the world to collect acoustics data in support of wildlife conservation efforts.<\/p>\n\n\n\n

SwiftOne: An upgraded terrestrial autonomous recording platform<\/strong><\/em><\/p>\n\n\n\n

Amongst many improvements, the updated S<\/em>wiftOne<\/strong><\/a> recording units offer better energy efficiency, a more precise clock, greater customization for frequency settings, voice memos, and greater microphone sensitivity.<\/p>\n<\/div>\n\n\n\n

Swifts have already been deployed on every continent. Based on user feedback, we are constantly improving the design and functionality of the unit. We are proud of the fact that all of the components of the Swift recorder (electronics, microphones, etc.) have been developed in-house at the Cornell Lab of Ornithology.<\/p>\n\n\n\n

In its regular configuration, the unit is powered by three D-cell batteries, which provide power to the unit and enable continuous data collection for 3 or more weeks at a sampling rate of 48 kHz. Currently, the maximum supported sampling rate is 96 kHz (16 bit resolution). Data are stored on a single full-size memory card (SD cards up to 512 GB). Daily recording schedules can be programmed through a configuration tool. We can easily make modifications (e.g., different housing designs) to the Swift according to the needs of the researchers.<\/p>\n\n\n\n

Following are some samples of recordings from Swift units deployed in various locations.<\/p>\n\n\n\n
