The SM4 is our next-generation acoustic recorder. It's smaller, lighter, easier to use, and has higher quality microphones than the SM3.
The SM3 is the right choice if:
Song Meter SM3
A customizable acoustic recorder for any combination of avian, terrestrial and marine research.
The Song Meter SM3 acoustic recorder is a multi-role bioacoustics recording device that can simultaneously record any combination of avian, terrestrial and/or marine life. Completely ruggedized, quick to configure and highly customizable from a configuration and scheduling basis, the SM3 can perform a wide variety of recording roles, and remain in the field for extended periods of time.
The SM3 can record in mono or stereo using a 16-bit .wav or optional .wac lossless compression format.
The SM3's built-in recording programs include daytime, nighttime, and continuous recording schedules with automatic configuration. Just pick your desired schedule and press the Start button to quickly begin making recordings.
You can also create sophisticated schedules and tailor configuration settings to suit your needs. Record birds on one day and automatically switch to capturing frog choruses on another. The SM3 can have scheduling details more finely grained than a minute. Make the SM3 stop recording on a specific date. Dynamically change sample rates. The SM3’s recording and configuration combinations are nearly endless.
Deploy an array of SM3s with the GPS option to determine location and direction of a sound source. The feature is useful when deploying SM3s in areas with thick vegetation. The GPS feature allows you to study all of vocalizing wildlife in a given area.
The SM3 can be outfitted with two sets of SMM-A1 acoustic microphones connected to multiple runs of cables. The SMM-A1 microphone applies gain at the microphone head to increase signal in the cables – a feature that significantly improves resistance to electrical noise interference.
A 20 meter, cabled hydrophone is also available to record activity below the waterline.
If you’re deploying the SM3 in areas prone to vandalism or theft, you can protect the SM3 and its critical data with lockable security housing.
The Song Meter SM3 power circuit was designed for extended deployments. In Sleep Mode, between scheduled recordings, the SM3 uses almost no power (around .05 mW), allowing it to remain idle for months at a time. Using high-quality alkaline batteries, the SM3 can record up to 260 hours of acoustic data with superb detail. That means longer deployments and fewer trips into the field. (Note: the SM3 owner's manual has a detailed listing of battery life per battery type and recording format.)
The Song Meter SM3 was designed for use in extreme weather conditions – from jungles and deserts to parts in between. The recorder has been subjected to environmental shock, drop testing, static discharge and extreme water incursion. We're so confident that the SM3 can endure the most extreme environmental conditions, we back it with a 3 year warranty. That means you can focus on research, not equipment.

One of the fastest and most intuitive spectrogram viewers available.
Song Scope software is fast and flexible – designed to help you quickly review recordings made by Song Meter or other conventional bioacoustics recording equipment. The software features a flexible spectrogram viewer that lets you scroll through large audio files and is typically 10-20 times more time efficient than simply listening. Song Scope’s Song Scape feature lets you visualize sounds on large temporal scales so you can measure sound energy in months and years instead of seconds.
