Song Meter SM4TS Acoustic Recorder

The Song Meter SM4TS is specially designed to help scientists triangulate the location of vocalizing animals. Delivering all the features of the industry standard Song Meter SM4, the SM4TS is a modified SM4 recorder that utilizes a sophisticated GPS time-sync receiver to synchronize the clocks on multiple recorders to within one millisecond.

Time Synchronization
Crystal oscillators used in clocks and electronics, including the SM4, are not perfect. One crystal might be faster or slower than another, and oscillations might speed up or slow down as temperatures change. 
The SM4TS GPS receiver can synchronize your recordings across multiple recorders to within one millisecond by syncing with each device’s clock. The start times are synchronized to commence on the second as indicated in the filename, and the sample rate is fine-tuned over the duration of the recording to keep the recordings synchronized — with less than one millisecond of error. 
 
High-Quality Recordings
The SM4TS features a second-generation built-in microphone that creates higher quality recordings than previous generations of Song Meter microphones. The low-noise microphone- has a superior signal-to-noise ratio, so you capture more sounds that matter to you.
 
Easy-to-use Scheduling
To get you started quickly, the SM4TS features easy-to-use Quick Start schedules, such as sunrise to sunset. You can also customize your schedules for specific recording needs. The free SM4TS Configurator software can be used to configure settings and schedules from a computer. The SM4TS Configurator software also provides a Security Lock option to prevent accidental changes to deployment and recording settings.
 
Large Storage Capacity
The SM4TS has two SD card slots that accept SDHC and SDXC cards. When fitted with two 1TB cards, the SM4TS 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.
 
FEATURES
By time-synchronizing multiple recorders, scientists can triangulate the approximate location of vocalizing animals based on the exact time each signal was detected across the array of microphones — providing valuable information about animal locations and behaviors.
Specialized, weatherproof GPS attachment allows you to time-sync multiple recorders, so you can triangulate the locations of vocalizing animals*
