Machine learning is a branch of artificial intelligence ... It is primarily identified in spectrograms because of its varying intensity and frequency. "Volcanic tremor isn't typically detected ...

Soundscape researchers use spectrograms to visually identify species and scan through hours of audio data. Using machine learning and neural networks, they pick out specific audio signals from ...

New research using machine learning shows finches may be sticking ... they’re often not listening to them — but rather looking at spectrograms, which are visualizations of audio files.
