“To identify a sound as belonging to a certain species requires an audio recording of sufficient quality and volume to be analyzed in sound editing software. The sound must then be compared to a sound recording of a known species. A poor quality recording that has been distorted with bad filtering techniques is next to worthless.”
Examples of poor quality sound recordings.
1973 Whoop-Howl from Puyallup, Washington
1978 Whoop-Howl from Snohomish County, Washington
Examples of good quality sound recordings.
