Wildlife Acoustics continues to innovate on the Song Meter platform to meet a wide range of active and passive monitoring and recording research requirements for terrestrial, aerial and marine environments. The Song Meter platform provides a powerful and expandable foundation to support a wide range of passive acoustic monitoring applications. Passive unattended recording products include the:
Leveraging our experience with the Song Meter platform, we created the Echo Meter which comprises of new innovation and design:
Wildlife Acoustics offers a software analysis solution to assist with post processing of the recordings called:
The configurable amplifier on the Song Meter Platform can support a variety of audio input sources including acoustic microphones to record birds and frogs, ultrasonic microphones to record bats, hydrophones for recording underwater acoustic signals from fish or cetaceans and a special night flight microphone to capture distant night flight calls from birds while attenuating sounds from below.
Several sample rates are available from one or two channels from 4kHz through 96kHz. The digital expansion connectors on the back of the SM2+ motherboard can host our SM2BAT+ dual-channel 192kHz or single 384kHz ultrasonic interface to record the echo-location calls of bats.
All recording file names are timestamped and include a programmable prefix to uniquely identify recordings made from each Song Meter.
Files can be recorded in standard uncompressed .WAV format. For longer recording capabilities, Wildlife Acoustics offers the Wildlife Acoustics Compression (WAC) capability. The WAC format may be configured in increments from lossy to lossless compression. The WAC format also supports triggers that can be set up independently on each channel to only record when acoustic events occur. Our WAC format can be converted back to a standard WAV format with our free WAC2WAV utility. The WAC2WAV utility is available at no charge from the Downloads section of our website.
The SM2+ can be easily programmed to record on simple time-of-day schedules or to implement the most complex monitoring protocols relative to local sunrise and sunset. The Song Meter can be configured directly from its front panel using an easy-to-use interface. For your convenience, you can also create, view and edit Song Meter configuration files with the Song Meter Configuration
Song Meter Configuration Utility
The software lets you visualize the recording schedule. Day and night are shown based on sunrise and sunset times specific to your geographic location and time of year. The software also estimates how long your recording schedule will run before you run out of flash card capacity or battery power. The software is free and can be found under Downloads.
