USV Detection

Before vocalizations can be detected, an audio folder, neural network folder, and output folder must be selected.

To process a single file:

1. Select the desired audio file in the "Audio Files" drop-down menu

2. Select an appropriate neural network in the "Neural Networks" drop-down menu

3. Click "Detect Calls"

4. Enter detection settings as described below, and click "OK"

To process files in a batch, or to process a single file with multiple networks:

1. Click "Multi Detect"

2. A list of the audio files in the current folder will appear. Select the desired audio files. Multiple files may be selected by holding the Ctrl key while clicking. Click "OK" to proceed.

3. After selecting the audio file(s), a box will appear, listing available neural networks. Select a maximum of two, and click "OK".

4. Enter detection settings as described below, and click "OK".

Detection Settings:

• Total Analysis Length

  • Length, in seconds, of the audio file to process.

  • Set to 0 to process the entire file

  • If analysis length is greater than the file duration, a warning will be displayed in the command line, and the entire file will be processed

• Frequency Cut Off High

  • Regions of the spectrogram above this value are ignored

• Frequency Cut Off Low

  • Regions of the spectrogram below this value are ignored

• Score Threshold

  • Detected items with a score (likelihood of being a hit) below this value are automatically set to rejected.
  • Default = 0; All detections will be saved to the detection file

• Append Date to File Name

  • If value is "1", the detection time will be appended to the end of the file name
