A new preprint from Morris Alper and colleagues introduces CallCleaner, a lightweight biodenoising model for cleaning up noisy field recordings of animal vocalizations (whales, lions, frogs, and more). It runs at over 90x realtime on a laptop CPU, with spectrogram comparisons showing clear noise removal before/after.
