Microphone Settings and Schedules
Each microphone connected to a SMART Controller can have its own Setting Profile and Schedule Profile. These profiles determine when the microphone is active; the settings it uses to detect, record, and analyze bat echolocations; and set the scheduling of microphone sensitivity testing and moisture clearing.
SMART MIC-1 Settings
Each SMART MIC-1 microphone connected to a SMART System can have independent settings. These settings govern everything from basic audio parameters to parameters defining how the SMART System detects bat pulses in each microphone's recorded audio.
Heater Settings
The SMART MIC-1 has a built-in heating element for removing condensation, which can reduce the sensitivity of its microphone elements.

Document History
This documentation receives frequent updates, which are described here.
Introduction
Song Meter® with Analysis and Remote Transfer, or SMART™, is a multi-channel, ultrasonic audio recording and analysis platform from Wildlife Acoustics®.
Getting Started
The first time you use a SMART System, we recommend setting it up in an accessible location, such as an office. This will make it easier to configure the SMART and perform any necessary troubleshooting.
Microphone Settings and Schedules
Each microphone connected to a SMART Controller can have its own Setting Profile and Schedule Profile. These profiles determine when the microphone is active; the settings it uses to detect, record, and analyze bat echolocations; and set the scheduling of microphone sensitivity testing and moisture clearing.
- Select a Microphone Setting Profile and Schedule Profile
  Each microphone attached to a single SMART Controller can have a unique Setting Profile and Schedule Profile selected from the ones included by default or that you create yourself.
- Creating and Editing Settings Profiles
  The Setting Profiles tab is where you can create and edit profiles to apply to each of the SMART System's microphones.
- SMART MIC-1 Settings
  Each SMART MIC-1 microphone connected to a SMART System can have independent settings. These settings govern everything from basic audio parameters to parameters defining how the SMART System detects bat pulses in each microphone's recorded audio.
  - Audio Settings
    The Audio Settings set basic parameters for incoming audio, such as recording format, sample rate, and gain.
  - Heater Settings
    The SMART MIC-1 has a built-in heating element for removing condensation, which can reduce the sensitivity of its microphone elements.
    - Cycle the SMART MIC-1 Heater On and Off
      The heater built into the SMART MIC-1 can be set to alternate between active and inactive at regular intervals during each schedule period, starting with active.
    - Enable the SMART MIC-1 Heater Once Per Schedule Period
      The heater can be set to activate once for a specified duration at the start of each schedule period. For example, you can enable the heater once per day, just before sunset.
    - Disable the SMART MIC-1 Heater
      The heater can be disabled for a given Setting Profile to reduce power consumption, but this is not recommended in most circumstances.
  - Calibration Settings
    The SMART MIC-1 can use its built-in ultrasonic speaker to test the sensitivity of its microphone elements at regular intervals during its recording schedule.
  - Settings for Triggered Recording
    Many settings available on the Setting Profiles tab only apply when Triggered Recording with Bat Call Analysis is enabled. These settings affect what kinds of signals will trigger recording and how the SMART will segment and process the resulting audio.
- SMART MIC-1 Schedules
  Each microphone attached to a SMART System can run an independent schedule, which determines when the microphone will monitor for bat activity each day.
- Change Microphone Name (Prefix)
  Each microphone attached to a SMART Controller can be given a unique name, or prefix. This prefix is used as part of the file name of any recording, results table, or log file associated with the microphone.
SMART Controller Configuration
Before you deploy the SMART System, you should configure basic system and network settings. These include login credentials, date, location, and network configuration settings.
Data Management
The SMART System stores recordings and logs on its internal drive initially, and it can periodically transfer new data to a USB or networked storage drive.
Installing SMART
Installing the SMART System on a wind turbine, meteorological tower, or similar structure requires careful planning. Proper connectivity, grounding, and microphone placement will help ensure a successful deployment.
Bat Activity Alarms and Control System Integration
The SMART System can integrate with a windfarm SCADA network or similar control system to perform acoustically triggered curtailment (ATC). You can define custom alarms that detect bat activity based on custom-defined parameters. When these alarms trigger, you can send control signals to other devices on a control system to trigger turbine shutdowns.
Troubleshooting
Specifications
SMART Enclosure
The SMART Enclosure is a preconfigured, weatherproof enclosure that can be purchased with the SMART System.
SMART API and Command Reference
The SMART System software includes utilities, command-line scripts, and APIs that can be used for additional customized programming of the SMART System.

Heater Settings

The SMART MIC-1 has a built-in heating element for removing condensation, which can reduce the sensitivity of its microphone elements.

When enabled, the heater can raise the temperature of the front face of the SMART MIC-1 to approximately 20°C above ambient temperature.

For a given Setting Profile, the heater can follow one of three basic behaviors:

Alternating between active and inactive during each schedule period
Active at the start of each schedule period
Always inactive

You can configure the heater to run simultaneously with triggered recording or set recording to pause while the heater is on using Triggered Recording with Bat Call Analysis > Pause Triggering When Heater Is On.

Choosing Heater Settings

Appropriate heater settings will depend greatly on a variety of factors, including, but not limited to, the following:

Microphone Position: A microphone that is sheltered overhead may experience less moisture collection and need less frequent heating.
Microphone Orientation: A microphone that is angled below horizontal will collect less moisture than one angled above horizontal.
Environmental Factors: Temperature, humidity, and precipitation patterns at the deployment site will affect how often moisture or frost collects on the microphone and how quickly it will evaporate.

In room temperature, low-humidity conditions, with the microphone angled horizontally, it can take up to thirty minutes for the heater to remove enough moisture that a microphone returns to normal sensitivity when tested with an external speaker.
