Frank Hamacher provided this sample of the echolocation call of the myotis daubentoni bat. The sound was recorded in a time extension mode which allows playback at 1/10 the original recording speed. This reduces the audio frequency of the sample by a factor of 10, making it audible to the human ear. The Spectrogram Ultrasound Display allows accurate measurement of time and frequency. |
