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.
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.
Pulse-Level Trigger Settings
During triggered recording with bat call analysis, several settings define what signals will trigger recording and be analyzed as bat calls. On the level of individual echolocation pulses, the SMART System can filter signals by frequency range and duration range.

Document History

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.
  - 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.
    - Pulse-Level Trigger Settings
      During triggered recording with bat call analysis, several settings define what signals will trigger recording and be analyzed as bat calls. On the level of individual echolocation pulses, the SMART System can filter signals by frequency range and duration range.
      - Minimum and Maximum Frequency
        The Minimum Frequency and Maximum Frequency parameters set the frequency range in which the SMART will look for possible bat calls. If a signal contains components both inside and outside this frequency range, only the portions inside the range will be analyzed.
      - Minimum and Maximum Pulse Duration
        The Minimum Pulse Duration and Maximum Pulse Duration parameters set how long or short a signal must be to trigger recording and be analyzed as a bat call. The typical duration of bat calls depends on the bat species and on the bat's behavior.
    - Pass-Level Trigger Settings
      The Maximum Sequence Duration, Pre-Trigger, and Post-Trigger settings directly determine the maximum duration of your triggered recordings. The Maximum Inter-Pulse Gap also affects how SMART splits audio into separate files depending on the recorded bat activity.
    - Constant-Frequency (CF) Filter
      The SMART System has a built-in filter to avoid triggering on signals within a set of defined parameters. This filter can help avoid false triggers on signals such as electrical interference or mechanical squeaks.
    - Bat Auto-ID Classifier Settings
      The SMART System can automatically identify each saved recording by bat species using the built-in Kaleidoscope® Pro Sound Analysis software.
- 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.

Pulse-Level Trigger Settings

During triggered recording with bat call analysis, several settings define what signals will trigger recording and be analyzed as bat calls. On the level of individual echolocation pulses, the SMART System can filter signals by frequency range and duration range.

You should tailor these settings to ignore sounds other than bat calls as much as possible, while including the vocalizations of your bat species of interest.

In acoustically triggered curtailment (ATC) deployments, these criteria may not be enough to completely separate bat calls from the noise produced by a given wind turbine. SMART's bat acitivity alarms provide a much more flexible logic system, which can be used as a second layer of filtering after the trigger parameters have taken effect.

Important:

The following processes will only occur on bat calls that satisfy the pulse-level trigger parameters:

triggered recording
measurement of bat call characteristics
bat species auto-ID
bat activity alarm logic
