Song Meter SM4 - The smallest and lightest dual-channel weatherproof  acoustic recorder available

The 4th generation Song Meter SM4 is a compact, weatherproof, dual-channel acoustic recorder capable of capturing large amounts of data from wildlife such as birds, frogs and aquatic life.

The SM4 features two built-in microphones, innovative scheduling tools, large data storage, and low power consumption - a unique combination of features that provide the longest deployment times of any acoustic recorder available.

Introducing a new generation of microphones.

The SM4 features entirely new, built-in microphones that create higher quality recordings than those from all previous Song Meter recorders. In addition to the built-in microphones, the SM4 includes two microphone ports - giving you the flexibility to record additional data from a cabled microphone; a new SMM-A2 cabled acoustic microphone, and/or hydrophone. See Microphone Specifications

Two channels give you more recording flexibility.

If you need to record two sources of audio at the same time, take advantage of the SM4's dual channel feature. Record in stereo or mono using the built-in microphones, or connect one or two cabled microphone/hydrophones. Adding additional runs of cable to the external microphone give you the ability to capture audio from far-off wildlife such as birds in the forest canopy, or frogs at a nearby pond.

Capture months of acoustic data.

The SM4 features new power circuitry that significantly increases deployment time over the SM3. In Sleep Mode, between scheduled recordings, the SM4 uses almost no power, allowing it to remain idle for months - meaning longer deployments, and fewer trips into the field.

Choose a schedule or create your own.

The SM4’s new Quick Start menu and Scheduler feature are an industry first. The SM4 comes with out-of-the box recording programs; including daytime, nighttime, and continuous recording schedules. Simply choose schedule and press the Start button. The SM4's new Scheduler features makes it easy to create custom schedules that suit your exact needs.

Capture more than a terabyte of data.

The SM4 has two SD card slots that accept SDHC and SDXC cards. When fitted with two 512GB cards, the SM4 can store over a terabyte of data. In the future, when higher capacity cards come to market, the SM4 will store even more.

Listen to your recordings in the field.

The SM4 features an integrated headphone jack to monitor activity in real-time.

Feel confident knowing you're backed by the longest warranty available.

The Song Meter SM4 was designed for use in extreme weather conditions - from jungles and deserts to parts in between. In fact, we're so confident that the SM4 can endure the most extreme environmental conditions, we back it with a 3 year warranty. That means you can focus on research, not equipment.
