Choosing between the SM3 and SM4?

Choosing between the SM3 and SM4?

You may have noticed that we not only have a new Song Meter recorder, the SM4, but we are also continuing to the offer the SM3. That's because while we recommend the SM4 for most cases, the SM3 has some unique features that you may require for your recordings. Answer the questions below to find out if you should be buying an SM3 or an SM4. 

How should I save, in .wac or in .wav?

How should I save, in .wac or in .wav?

If you have used our ultrasonic Song Meters before, you may be familiar with two different options for saving our recordings, triggered .wav, and our proprietary compressed format, .wac. While we recommend triggered .wav format in almost all cases, there are a few instances where it may benefit you to use .wac format instead.

  • First, we recommend our ultrasonic users record to triggered .wav format for several reasons:
    Triggered .wav format comes with noise scrubbing capability, which allows for more accurate triggers. This means you won’t be wasting card space with recordings that have been falsely triggered by non-animal noises, such as rain. Though .wac files takes up less space than .wav, this could actually offset the amount of space that would have been saved recording in a compressed format if you are in an area prone to ultrasonic noise.
  • Wav is 30% more energy efficient than .wac and can be used directly for ZC analysis
  • If you are using a Song Meter SM3, you will have automatically embedded metadata in your .wav files.

So when is it preferable to use .wac?

If you are interested in GPS tracking, you may find it more valuable to record to the .wac format. .Wac recordings take GPS information every second, allowing for continuous tracking data. While some GPS data is available with .wav, you will have fewer data points than in .wac.

Another advantage of .wac is independent triggering. If you are recording different species on different channels, you may want only one channel to trigger at once. For example, you may want to record birds on one channel, and bats on another. You wouldn’t want bats to trigger recording on both channels if there won’t be another birds to record for several hours. In situations such as these, the .wac format will be much more space saving than .wav.

Dive into possibilities: The new SM3 aquatic models

Dive into possibilities: The new SM3 aquatic models

The SM3 aquatic is a device that's tougher than any we’ve ever made. The all new Song Meter features a rugged, die-cast aluminum body and an unprecedented 3 year warrantee. It’s a machine you can count on in the most extreme of environments.

But no two customers have the same demands out in the field, and that’s why it’s also our most flexible product line. Just about any feature can be tailored to fit your needs.

  • There's an ultrasonic and acoustic model
  • They're the only recorders of their kind to simultaneously monitor above and below the water line
  • Record any combination of marine, terrestrial, and avian life
  • Monitor all kinds of aquatic life, from 20Hz to 48kHz
  • Perform acoustic recording and noise logging simultaneously
  • Use out of the box recording programs, or customize your own.
  • Save time by choosing from a menu of standard options, such as daytime, nighttime, or continuous.
  • Or, create your own custom schedule with our easy-to-use configurator software.

Multiple Hardware Options

Outfit the SM3 to your needs. You can choose to record with the standard acoustic hydrophone, or you can opt to upgrade to an ultrasonic hydrophone. See our accessories page for more details.
