title: A Low-Cost Open-Source Acoustic Recorder for Bioacoustics Research.
abstract: Acoustic recorders are the primary tool used in marine bioacoustics; however, available devices are either expensive or lack self-calibration capabilities that are critical for high-quality measurements. Moreover, the software used in proprietary designs can be inflexible and may involve unknown processing steps. To address this, we have designed a miniature low-cost yet high-performance acoustic recorder that features open-source hardware and software. Circuitry is included for self-calibration, making it possible to evaluate device performance in situ. Our intention is that the design will develop in conjunction with the needs of the bioacoustics community.
