Audiolog

Audiolog is a low-cost, small and energy-saving acoustic recorder.

It has a wide range of application and is field ready for acoustic surveys of wildlife and biodiversity.

Audiolog is a perfect tool to carry out acoustic monitoring without altering the behaviour of the recorded wild animals.

Additional performances:

Technical

Low distortion digital MEMS microphone with 64dB signal-to-noise ratio and -26dB sensitivity
Programable sampling frequencies from 10kHz up to 48kHz
Embedded 3,3V 1800mAh rechargeable battery providing hundreds of hours of continuous recording (>200 hours @ 48kHz and >800 hours @ 10kHz). Autonomy can be extended with the use of external power bank
Compatible with 512 Gb SD card (Native: 16 Gb)

Ergonomic

Turnkey hardware: the Audiolog comes with a waterproof enclosure and its own embedded battery
The dedicated GUI is intuitive and recording times and sampling rates can be program rapidly, even for several Audiolog in parallel
The lithium battery is rechargeable through a USB-C port, so no need to buy and manage sets of batteries
The Audiolog’s dimensions are 71mm*42mm*28mm.

AVAILABLE FOR PRESALE

User interface

A dedicated software is provided for programming several Audiologs over micro USB ports. It allows to configure the audio sampling frequency and the exact timings of audio recordings over one or more periods. The software can also be used to retrieve and organize output audio files in compressed or uncompressed .wav format.

Developed by researchers

Audiolog has been developped to address the specific needs of academics in the field of wildlife monitoring. To ease life on the field and provides useful material for studies.

Audiolog has been developped within a collaboration between ecologists at the CEFE (Centre for Functional and Evolutionary Ecology) laboratory and engineers at LIRMM (computer, robotics and microelectronics laboraory) in Montpellier.

Audiolog is the first of a complete family of product for wildlife monitoring. Future models are under development and includes ultrasound microphones, hydrophones, GPS and inertial sensors.
