Song Meter SM4 Acoustic Recorder

In stock

Setting the standard for bird and wildlife audio recorders.

The Wildlife Acoustics Song Meter SM4 is the proven industry standard wildlife audio recording equipment, specially engineered to deliver quality sound recordings of birds, frogs, and other vocal animals in the wild.

Overview :

High Quality Recordings

MAXIMIZE DETECTION AND FIDELITY.

The SM4 features two second-generation built-in microphones that create higher quality recordings of birds and vocalizing animals than previous generations of Song Meter microphones. The low-noise microphones have a superior signal-to-noise ratio so you capture more wildlife sounds that matter to you.

Dual-Channel Recording Capability

TWO CHANNELS FOR MORE RECORDING FLEXIBILITY. Take advantage of the SM4’s dual-channel feature to ensure that recording continues – even after one microphone is disabled by wildlife-incurred damage. Record in stereo or mono using the built-in microphones, or connect one or two cabled microphones. Adding additional runs of cable to the external microphone gives you the ability to capture audio from far-off wildlife such as birds in the forest canopy or frogs at a nearby pond.

Easy-to-use Scheduling

CHOOSE A SCHEDULE OR CREATE YOUR OWN. To get you started quickly, the SM4 features easy-to-use Quick Start schedules, such as sunrise to sunset. You can also customize your schedules for specific wildlife sound recording needs. The free SM4 Configurator software can be used to configure settings and schedules from a computer. The SM4 Configurator software also provides a Security Lock option to prevent accidental changes to deployment and recording settings.

Large Storage Capacity

CAPTURE TERABYTES OF DATA.

The SM4 has two SD card slots that accept SDHC and SDXC cards. When fitted with two 1TB cards, the SM4 can store up to two terabytes of data. In addition, you can save card space by using W4V Compression. The format doubles the capacity of your SD cards with no noticeable degradation of recording quality. The resulting W4V files can be opened with and/or converted to uncompressed WAV files using the free version of Kaleidoscope software.
